Mediatube Corp v Bell Canada 2017 FC 495 Locke J
2,339,447 / Internet Protocol Television / Fibe TV, FibreOp
In his substantive decision in Mediatube v Bell 2017 FC 6, Locke J held that costs awarded to Bell should be elevated by 50% for the infringement case (all issues except punitive
damages) and awarded on a solicitor-and-client basis for the punitive damages case, essentially
on the basis that the plaintiffs could not have had a reasonable belief that they had a good
arguable case [234]: see here. This decision clarified the application of this holding. While the
decision turns largely on the facts, there are a couple of general points of interest.
First, Locke J held that in the Federal Court, the term “solicitor-and-client costs” generally means
a full indemnify basis, not only a substantial indemnity basis: [33].
Second, he noted that in allocating costs between the infringement case and punitive damages
case, there was a trade-off between precision and ease of calculation, and he chose to adopt a
relatively simple but less precise approach: [13].
Third, a 50% elevation of costs on the infringement case plus solicitor and client costs on the
punitive damages case, sounds like a serious costs sanction. If I have done the calculations
correctly, Bell’s actual total costs, including legal fees and disbursements, were just over $7.9
million ($7,901,718 - it’s not clear to me whether this figure includes tax) [5]. The grand
total actually awarded on the enhanced basis, including tax, was $2,114,582 [97], or $1,931,876 before tax. This means that the
costs award, even on this significantly elevated basis, in respect of a case in which the plaintiffs
could not have had a reasonable belief that they had a good arguable case, was only about 25% of
Bell’s actual costs. Bell is out of pocket by $5 million for having defended a suit which never
should have been brought.
It is more than two years ago that the Rules Committee released an ambitious discussion paper
on costs. Perhaps I’ve missed it, but I can’t recall having seen any follow-up.

Prior Use by Inventor Anticipates Patent
Packers Plus Energy Services Inc v Essential Energy 2017 FC 1111 O’Reilly J
2,412,072
The technology embodied in Packers Plus’ 072 patent relates to a method for fracking by selective transmission of fluids to different segments of a wellbore by way of a tubing string consisting of a series of packers and ports which can be operated independently [8]. Yesterday’s post discussed O’Reilly J’s holding that the patent was not infringed. Today’s post discusses his holdings that it was invalid as anticipated and for obviousness.
Confidentiality
The anticipation holding presents a classic cautionary tale regarding public disclosure prior to filing. It turned on the fact that the patentee, Packers, had itself used the invention in the field in the fall of 2001, more than one year before the Canadian filing date [65ff]. That use was not really disputed [82]. Rather, Packers argued that the use was not anticipatory, under 28.2(1)(a), either because it was used in circumstances in which all the recipients of the information were required to keep it confidential, or because it came within the experimental use exception [64].
Though there were some indicia of confidentiality, ultimately the confidentiality argument failed on the facts. As I read it, what happened is that in the fall of 2001, Packers, which was already established in the oil-field service industry as a provider of down-hole tools, was asked by a client to do a job in a gas well. Mr Themig, one of the inventors and a principal in Packers, came up with what seemed to be a pretty good solution. The client agreed, and it was implemented. It was only after the fact that Mr Themig began to appreciate just how good a solution it really was, and Packers ultimately set the wheels in motion to apply for a patent. My sense is that in this industry, each hole and every job is a bit different, so it was not out of the ordinary for a high-end firm such as Packers to devise a solution that was strictly novel, in the sense of being tailored to the particular job. That of course does not mean that every solution is patentable, and it is perhaps for that reason that Mr Themig did not take all the steps necessary to make it sufficiently clear that the use of the method was to be considered confidential. It seems to me that the one year grace period afforded under the Canadian Patent Act is intended to address this type of situation. In some industries inventions are products of a patent-oriented lab, but in others they emerge from practical innovators in the field, and in the latter case it is not always reasonable to ask a person to keep patent law requirements in mind while trying to solve a problem for a client. The grace period responds to that problem; but the grace period is necessarily limited and in this case the inventor did not proceed to filing quickly enough.
Experimental Use
The experimental use argument turns on the question of what it means for a use to be “experimental.” In some cases, such as clinical trials of a drug prior to commercialization, the answer is clear, but in the case, the use itself was commercial.

Slice and Dice to Avoid Infringement?
Packers Plus Energy Services Inc v Essential Energy 2017 FC 1111 O’Reilly J
2,412,072
The technology embodied in Packers Plus’ 072 patent relates to a method for fracking by selective transmission of fluids to different segments of a wellbore by way of a tubing string consisting of a series of packers and ports which can be operated independently [8]. My understanding from general news sources is that the patented technology is widely used in the fracking industry. O’Reilly J held the 072 patent to be invalid as anticipated and for obviousness. These issues are dealt with in subsequent posts.
O’Reilly J also held that even if the 072 were valid, it was not infringed, nor had the defendant, Essential, induced infringement [3]. He held that in light of the claim construction, “it is clear that Essential’s equipment. . . infringes the ‘072 patent when used in an open-hole fracturing operation” [38]. However, the claims in issue were method claims, and Essential only supplied and installed the equipment, but did not carry out the complete method [44], [52], [53]. Packers Plus therefore argued inducement and joint infringement.
On inducement, O-Reilly J noted that the first step of the three-part test for inducement set out in Corlac v Weatherford 2011 FCA 228, [162], requires an act of infringement by a direct infringer. He then held:
This holding, that inducement requires direct infringement by a single party, appears to me to be novel. The holding in Corlac itself was this:
This does not hold that there must be a single direct infringer, but rather implicitly assumes that there is. The question of whether all the acts constituting the patented method must be carried out by a single actor was simply not at issue. The Corlac test assumes that there is direct infringer, and asks when it is permissible for the patentee to pursue the inducer instead. The first prong of the test is (my emphasis):
Again, this does not hold that there must be a single direct infringer. Rather it assumes (“the”) that there is, and asks whether that direct infringer had completed the act of infringement. So, in Dableh v Ontario Hydro [1996] 3 FC 751 (FCA), cited in this paragraph of Corlac, the first prong was not satisfied because the use by the putative direct infringer had not proceeded beyond experimental use, and so there was no direct infringement at all (though a quia timet injunction was nonetheless granted). In AB Hassle v. Apotex, 2002 FCA 421, also cited in Corlac as authority for this test, the allegation was the drug would be prescribed off-label for an infringing use, and the first prong was not satisfied because the trial judge was not persuaded that this would actually happen [25]. Again, there was no direct infringement at all, regardless of the number of parties involved (In the third case cited in Corlac, MacLennan 2008 FCA 35, inducement was established.)
While I have not reviewed all the Canadian inducement cases, I am not aware of any which holds that the direct infringement must be carried out by a single party. As a general matter, this question is a controversial one. The evident concern with O’Reilly J’s holding is that in industries in which key operations are routinely carried out by a variety of different parties in conjunction, it might be impossible to effectively enforce patent rights. Perhaps of even greater concern, parties might be able to arrange their operations, for example by subcontracting certain tasks, so as to avoid infringement. The issue has been addressed most recently by the US Federal Circuit in Akamai v Limelight 797 F.3d 1020 (Fed Cir 2015), on remand from 134 S.Ct. 2111, holding that in order to find induced infringement, it is not necessary to prove that all the steps were committed by a single entity. I also note that under s 60(2) of the UK Patents Act a party is liable for infringement if "he supplies . . .any of the means, relating to an essential element of the invention, for putting the invention into effect when he knows. . . that those means are suitable for putting, and are intended to put, the invention into effect." It seems perfectly clear that Essential would be liable under this provision, as there is no requirement for direct infringement, but only that the invention be put into effect, and, as noted above, O'Reilly J clearly held at [38] that the invention would be put into effect by the use of Essential's equipment. That statutory provision is of course not directly applicable in Canada, but it highlights some of the policy considerations related to O'Reilly J's holding.
This is not to say that O’Reilly J was wrong to say that there must be a single direct infringer. Divided infringement raises difficult policy and doctrinal questions, which I won’t explore in this post, as O’Reilly J’s holding on infringement was not crucial in light of his holding that the patents were invalid. Moreover, on the facts of this case, it might well be that even if there was a party who should be held liable for infringement, that party is not Essential. My point here is simply that his holding is novel and controversial, and that it does not follow from Corlac and the cases cited therein.
UPDATE: For an even more recent decision of the US Fed Cir, see Travel Sentry v Tripp, released yesterday, and discussed on Patently-O. Note that, as discussed here, the EWCA in Warner-Lambert [2015] EWCA Civ 556, has a thorough discussion of the European position, which contrasts with the US approach.

[51] Packers has not produced evidence of direct infringement by anyone. It merely
implies that Essential’s main customers, the operating companies who own and operate
the wells, are the infringers. However, the evidence shows that there are often numerous
entities involved in a fracturing job, including the operating company and the various
service entities it hires – drilling companies, pumping companies, cementing companies,
tool companies, and fracturing companies. It is unclear who the direct infringer would be
in that situation.
[55] Perhaps the collectivity of companies involved in a fracturing operation could be
said to work the method claimed in the ‘072 patent. However, each of their respective
contributions to the operation would amount to a partial or, at most, an indirect
infringement, not a direct infringement of the patent. Therefore, Packers cannot meet the
first branch of the test for inducement. It has not proved direct infringement by anyone.
This holding, that inducement requires direct infringement by a single party, appears to me to be novel. The holding in Corlac itself was this:
[162] It is settled law that one who induces or procures another to infringe a patent is
guilty of infringement of the patent.
This does not hold that there must be a single direct infringer, but rather implicitly assumes that there is. The question of whether all the acts constituting the patented method must be carried out by a single actor was simply not at issue. The Corlac test assumes that there is direct infringer, and asks when it is permissible for the patentee to pursue the inducer instead. The first prong of the test is (my emphasis):
[162] First, the act of infringement must have been completed by the direct infringer.
Again, this does not hold that there must be a single direct infringer. Rather it assumes (“the”) that there is, and asks whether that direct infringer had completed the act of infringement. So, in Dableh v Ontario Hydro [1996] 3 FC 751 (FCA), cited in this paragraph of Corlac, the first prong was not satisfied because the use by the putative direct infringer had not proceeded beyond experimental use, and so there was no direct infringement at all (though a quia timet injunction was nonetheless granted).

Dependent Claims and Obviousness
Ciba Specialty Chemicals Water Treatments Ltd v SNF Inc 2017 FCA 225 Pelletier JA: Rennie
JA, concurring reasons by Woods JA aff’g 2015 FC 997 Phelan J
2,515,581
A post on the McCarty Tetrault snIP/ITs blog has pointed out an issue that I had missed in Ciba Specialty Chemicals Water Treatments Ltd v SNF. The authors note that the FCA held (my emphasis):
They remark that
I suggest that the reason for the apparent conflict may be that in Ciba v SNF, according to Phelan J’s trial decision:
So, the FCA statement at [97] may only be saying that in this particular case none of the dependencies added anything potentially non-obvious. However, this is not entirely satisfactory. Phelan J analyzed obviousness in terms of the inventive concept, and since he concluded all the claims shared a single inventive concept, to hold that in this case all the claims rise or fell together (at least so far as obviousness is concerned), is not inconsistent with Zero Spill. But as discussed here, a key point of the FCA decision in Ciba v SNF was that it is preferable to “avoid[] the inventive concept altogether and pursu[e] the alternate course of construing the claim” [77], which is what the FCA did in undertaking its own obviousness analysis de novo. Since the FCA did not rely on the inventive concept at all in assessing obviousness, much less on there being a single inventive concept, it is not clear why the claims should stand or fall together.
I suspect that what happened is simply that on appeal the parties treated all the claims as standing or falling together, in light of Phelan J’s holding at trial, and consequently so did the FCA, even though the rationale had shifted. In any event, this particular point was tangential in Ciba v SNF, whereas in Zero Spill, as the snIP/ITs authors point out, it was the very issue on which the FCA reversed the court below. Moreover, the holding in Zero Spill is clearly correct as a matter of principle. All things considered, I think it may confidently be said that the FCA’s statement in [97] of Ciba v SNF, turned on the particular facts of the case, and the holding in Zero Spill remains the law.
2,515,581
A post on the McCarty Tetrault snIP/ITs blog has pointed out an issue that I had missed in Ciba Specialty Chemicals Water Treatments Ltd v SNF. The authors note that the FCA held (my emphasis):
[97] The result is that Claim 1 is obvious and, since all other claims are directly or
indirectly dependent on Claim 1, the ‘581 Patent is invalid.
They remark that
This holding is difficult to reconcile with prior Federal Court of Appeal jurisprudence not
cited by the court. In Zero Spill Systems (Int’l) Inc. v. Heide [2015 FCA 115], the Federal
Court of Appeal reversed the Federal Court on this very holding:
The Federal Court was obliged to consider the validity of the ’064 Patent
claim-by-claim. Not doing so was a legal error. Notwithstanding that Claim 13 is
actually an independent claim, the nature of dependent cascading claims is to
narrow the claims upon which they depend: Purdue Pharma v. Pharmascience
Inc., 2009 FC 726, 77 C.P.R. (4th) 262 at paragraph 10. The practical effect of
this on anticipation or obviousness is that eventually a claim may be sufficiently
narrow to escape these prior art-based attacks, even though the broader claims
may be invalid. [94]
I suggest that the reason for the apparent conflict may be that in Ciba v SNF, according to Phelan J’s trial decision:
[26] As a result of the nature of the dependencies and the state of the art, if Claim 1 is
invalid, then its dependent claims are likewise invalid. Dr Farrow, Ciba’s principal
expert, was correct in his view that there was only one inventive concept that applied to
all claims in the 581 Patent. This case rises or falls on Claim 1.
So, the FCA statement at [97] may only be saying that in this particular case none of the dependencies added anything potentially non-obvious. However, this is not entirely satisfactory. Phelan J analyzed obviousness in terms of the inventive concept, and since he concluded all the claims shared a single inventive concept, to hold that in this case all the claims rise or fell together (at least so far as obviousness is concerned), is not inconsistent with Zero Spill. But as discussed here, a key point of the FCA decision in Ciba v SNF was that it is preferable to “avoid[] the inventive concept altogether and pursu[e] the alternate course of construing the claim” [77], which is what the FCA did in undertaking its own obviousness analysis de novo.

What is the Jurisdiction of the Federal Court under s 20(2) of the Federal Courts Act?
Alpha Marathon Technologies Inc v Dual Spiral Systems Inc 2017 FC 1119 Kane J
In Alpha Marathon the plaintiff claimed to be the co-inventor of an invention patented by the defendant in the US [4]. The plaintiff sought, in substance, a declaration that it was the entitled to the US patent rights: [4], [20]. Kane J granted the defendant’s motion to strike the statement of claim on the basis that the Federal Court lacks jurisdiction over the dispute [108]. In so doing, Kane J provided an extensive and helpful review of the law related to the jurisdiction of the Federal Court under s 20(2) of the Federal Courts Act. I agree with Kane J's conclusion that the FC lacks jurisdiction in this case, but I must admit that I remain puzzled as to the exact limits of the Court’s jurisdiction in such matters.
As Kane J noted [37], [52], the basic test for the jurisdiction of the Federal Court is set out in ITO-Int'l Terminal Operators v. Miida Electronics [1986] 1 SCR 752, 766:
This has been re-affirmed in Windsor (City) v Canadian Transit Co, 2016 SCC 54, which, at [25ff], emphasized the importance of determining the “essential nature” of the claim.
The main question in Alpha Marathon turned on the first branch of the test. The plaintiff relied entirely on s 20(2) of the Federal Courts Act, as interpreted in Kellogg Company v Kellogg, [1941] SCR 242, as providing the necessary statutory grant of jurisdiction [46], [60].
Subsection s 20(2) gives the FC concurrent jurisdiction in all cases “in which a remedy is sought under the authority of an Act of Parliament or at law or in equity respecting any patent of invention.” The defendants argued that s 20(2) is not applicable “because the words ‘any patent of invention’ in that section mean a patent of invention obtained in Canada, not simply an invention or a patent of invention obtained in another country” [38, my emphasis]. This seems right to me. As a matter of statutory interpretation, it would appear that “patent of invention” in s 20(2) means the same thing as “letters patent for an invention” under the Patent Act, s 2, and the Patent Act clearly refers to Canadian patents. This is not express, but clear nonetheless from eg s 4(2) which provides that “The Commissioner shall . . . do all acts and things requisite for the granting and issuing of patents of invention.” That provision is evidently not empowering the Commissioner to grant US patents.
Kane J accepted this point:
See also [67], emphasizing the need for a Canadian patent.
The defendant argued that s 20(2) was satisfied because the dispute related to “an invention made in Canada and by Canadians.” But s 20(2) does not require merely that the invention is somehow Canadian; it requires that the remedy sought is in respect of a Canadian patent. In this case no remedy was sought relating to any Canadian patent, nor even to a potential Canadian patent application. I should note that the Plaintiff did not actually seek a declaration as to the ownership of the US patent, but rather a declaration that it was the owner of the invention claimed in the corresponding US patent application; an injunction requiring the defendants to convey their interest in the US patent application to the plaintiffs; and injunction prohibiting the defendants from infringing the US patent application [20]. The reference in the pleadings was to the US application, notwithstanding that the US patent had actually been granted: US Patent No. 6,902,385 [18]. Presumably this was because a request for a declaration as to ownership as to the US patent would be self-evidently absurd; but dressing it up as a request for relief related to the US application does not change the substance.
While that point was enough to dispose of the issue, Kane J undertook a more general review of s 20(2), with the key cases being Kellogg, Radio Corporation of America v Philco Corporation (Delaware), [1966] SCR 296, and Cellcor Corp v Canada v Kotacka [1977] 1 FC 227, 27 CPR(2d) 68 (FCA).
I discussed Kellogg in my post on SALT Canada Inc v Baker 2016 FC 830, in which Boswell J refused to make a declaration as to ownership of a granted patent pursuant to s 52 of the Patent Act, on the view that the FC lacks jurisdiction when the essential issue is the ownership based on the interpretation and application of contract law principles. My post suggested that the parties had overlooked Kellogg , which might be read as holding that the statutory grant could be found in s 22(c) of the Exchequer Court Act, which is substantively the same as the current s 20(2) of the Federal Courts Act.
Kane J held that the jurisprudence subsequent to Kellogg reflects a more constrained approach to the interpretation of the Federal Courts Act [69]. Her conclusion is perhaps best summarized by Tremblay-Lamer J in Peak Innovations, 2009 FC 661, [9], quoted with approval at [77]:
And see [78] reiterating the point. As I understand it, the point is that s 20(2) is effectively solely to enable the Federal Court to grant the appropriate remedy, after substantive jurisdiction has been established under some other provision.
I’m not sure I’m entirely persuaded that is the correct interpretation of s 20(2). The text of s 20(2) states that “The Federal Court has concurrent jurisdiction in all cases. . . in which a remedy is sought. . . respecting any patent of invention .” It does not say, “The Federal Court has concurrent jurisdiction in all cases . . . to grant a remedy . . . respecting any patent of invention.” I would say that on its face s 20(2) gives jurisdiction to the Federal Court (subject to the other branches of the ITO test). That is the reasoning on which the SCC in Kellogg based its interpretation of the provision.
The primary authorities for a more restrictive interpretation of this proposition were Radio Corp and Cellcor. I acknowledge that in writing my post on SALT Canada v Baker 2016 FC 830 I had overlooked both of those cases. And it is also true, as pointed out by Kane J [73], that in Cellcor at [11] the FCA perceived a possible conflict between Radio Corp and Kellogg, and chose to follow Radio Corp. But I’m not convinced there really is a conflict between Radio Corp and Kellogg.
Kellogg was a conflict proceeding in which the main question was which of the parties, Kellogg Co or Kellogg, was the true inventor. The Commissioner had made a decision in favour of Kellogg, pursuant to the procedure set out in then s 44, and that decision had been duly appealed by Kellogg Co to the Exchequer Court pursuant to s 44(8) of the Patent Act. It was undisputed that the Exchequer Court had jurisdiction in that respect. Kellogg Co had also pleaded in the alternative that even if Kellogg were the true inventor, Kellogg was an employee of Kellogg Co. In that case, the remedy sought was that Kellogg Co should be adjudged to be “the owner of the invention made by [Kellogg], and that the respondent should be directed to execute an assignment to the appellant of the entire right, title and interest in and to the invention and the application relating to it” (246). The Exchequer Court had ordered the alternative pleading struck on the basis of lack of jurisdiction, and the SCC reversed, in part because s 20(2) (then s 22(c)) gave jurisdiction because “the remedy sought by the appellant. . . is evidently a remedy in Equity respecting a patent of invention” (250).
Radio Corp also involved a conflict proceeding, and one of the parties, dissatisfied with the Commissioner’s decision, had appealed pursuant to the same provision (by then 45(8)). But in addition to attacking the Commissioner’s decision on the claims which had been found to be in conflict, the appellant had also attacked a variety of other claims in relation to which no conflict had been found (301). The SCC reviewed the history of the relevant provisions, pointing out that under the Act of 1906, conflict proceedings were to be decided by a board of arbitration, while in Hutchins Car Roofing Co ( 1916), 16 Ex CR 391, Cassells J had held that what is now s 20(2) gave the Exchequer Court concurrent jurisdiction with that board (303). The result was that there were two distinct procedures for dealing with conflicting applications. This led to the enactment of the s 44(8) (originally 22(7)), providing for an appeal procedure from a decision of the Commissioner, and, by implication, depriving the Exchequer Court of original jurisdiction in such matters. As the SCC stated (my emphasis):
I read this as saying that Cassells J’s interpretation of s 20(2) was not wrong, and indeed was confirmed by s 44(8), which did not grant the Exchequer Court jurisdiction respecting conflicts, but rather limited the jurisdiction that was already conferred by s 20(2). That is, if the Act did not provide any other method for resolving a conflict, the Federal Court would have jurisdiction under s 20(2), but given that an alternative procedure had been established, s 20(2) could not be used to circumvent that alternative procedure.
A purposive analysis arguably also provides some support for a broad reading of s 20(2). It rounds out the statutory scheme in the same way that s 7(b) of the Trade-marks Act rounds out that Act. S 7(b) allows a trade-mark owner to bring an action in Federal Court based on a registered mark, and plead 7(b) in the alternative, rather than being forced to resort to a new proceeding in provincial superior court if its registration should be held invalid. Similarly, as in Kellogg, s 20(2) allows a plaintiff to raise ownership as an alternative to its claim to inventorship, when the factual issues are closely enmeshed, rather than having to resort to a new proceeding in a different court.
It may also be possible to reconcile Cellcor with Kellogg, but not so readily. In Cellcor the plaintiff sought a declaration that it was the party entitled to apply for a Canadian patent on the basis that it was the inventor of the specified invention, which had been stolen by the defendant, who intended to file an application in Canada. However, it appears that the plaintiff had not actually applied for a Canadian patent. Counsel for the defendant did argue that “the Court cannot exercise its jurisdiction under section 20 unless a right to relief exists by virtue of some other statutory provision,” but it is not clear to me that the Court accepted this proposition. The Court held (my emphasis):
This could be read as saying that the Act provided for a process by which a party may apply for a patent, and to decide who is entitled to the grant of a patent in the case of a dispute, and that specific procedure displaces any general jurisdiction granted by s 20(2). This suggests a distinction between Kellogg and Cellcor on the basis that there is a specific procedure for determining a conflict between inventors, but there is no specific procedure for determining ownership, for example as between an employer and employee. So, in Comstock Canada v Electec Ltd., (1991) 38 CPR(3d) 29, 49-50 (FCTD), the Federal Court held it had jurisdiction under s 20(2) to consider a dispute as to inventorship in respect of a granted patent. Section 52, which allows the FC to order an entry in the patent records to be varied, was invoked purely as remedial authority. (Though note that Muldoon J in Comstock relied on McCracken v Watson, [1932] Ex CR 83, 88, which actually adopts a restrictive view of s 20(2)). In any event, if Comstock was rightly decided, it seems to me that on the same basis, s 20(2) gives concurrent jurisdiction to the FC to determine who, as between the employer and employer is entitled to apply for the Canadian patent, subject to the requirement under the second branch of the ITO test that the question of inventorship is essential to the disposition of the issues.
But these distinctions may be too fine. In Kellogg the underlying issue was the employer / employee relationship, while in Cellcor it was misappropriation of confidential information, both leading to dispute over ownership of a potential Canadian patent application. It strikes me that there is a real distinction between disputed inventorship and ownership, because “inventor” is a concept found in the Patent Act, and inventorship must therefore be defined under that Act, whereas ownership disputes based on contracts, confidential information, or the employer / employee relationship, turn on the proper law related to the dispute. But by the same token, I don’t see any principled distinction between a dispute based on confidential information and one turning on the employer / employee relationship,. If the Federal Court has jurisdiction in the one type of case, I would think it should also have it in the other type, and vice versa.
If Kellogg and Cellcor cannot be reconciled, perhaps it was Cellcor which was wrongly decided. On the other hand, rather than straining to reconcile Kellogg with subsequent cases, maybe it is better to acknowledge, with Kane J [69], that the law has moved on. While Kellogg is SCC authority, it is long in the tooth. Old authority is not necessarily bad authority; indeed, the authority of a case may grow with time, as it is regularly cited. But that is not the case here; while Kellogg itself is regularly cited, as Kane J noted [61], it is cited for the proposition that the Federal Court may resolve “incidental” contractual issues, and not for its holding on s 20(2). Moreover, the holding on s 20(2) was in the alternative, though perhaps not strictly obiter.
In any event, regardless of the theoretically correct interpretation of s 20(2), Kane J’s review of the case law indicates that the Federal Court has generally been reluctant to accept concurrent jurisdiction. It not clear to me why this should be. No doubt there are some cases in which the Federal Court would have concurrent jurisdiction under the Kellogg reading of s 20(2), yet where another court would be more suitable, but in such cases the Federal Court could decline to exercise its jurisdiction on the basis of forum non conveniens.
In Alpha Marathon the plaintiff claimed to be the co-inventor of an invention patented by the defendant in the US [4]. The plaintiff sought, in substance, a declaration that it was the entitled to the US patent rights: [4], [20]. Kane J granted the defendant’s motion to strike the statement of claim on the basis that the Federal Court lacks jurisdiction over the dispute [108]. In so doing, Kane J provided an extensive and helpful review of the law related to the jurisdiction of the Federal Court under s 20(2) of the Federal Courts Act. I agree with Kane J's conclusion that the FC lacks jurisdiction in this case, but I must admit that I remain puzzled as to the exact limits of the Court’s jurisdiction in such matters.
As Kane J noted [37], [52], the basic test for the jurisdiction of the Federal Court is set out in ITO-Int'l Terminal Operators v. Miida Electronics [1986] 1 SCR 752, 766:
1. There must be a statutory grant of jurisdiction by the federal Parliament.
2. There must be an existing body of federal law which is essential to the disposition of
the case and which nourishes the statutory grant of jurisdiction.
3. The law on which the case is based must be "a law of Canada" as the phrase is used in
s. 101 of the Constitution Act, 1867 .
This has been re-affirmed in Windsor (City) v Canadian Transit Co, 2016 SCC 54, which, at [25ff], emphasized the importance of determining the “essential nature” of the claim.
The main question in Alpha Marathon turned on the first branch of the test. The plaintiff relied entirely on s 20(2) of the Federal Courts Act, as interpreted in Kellogg Company v Kellogg, [1941] SCR 242, as providing the necessary statutory grant of jurisdiction [46], [60].
Subsection s 20(2) gives the FC concurrent jurisdiction in all cases “in which a remedy is sought under the authority of an Act of Parliament or at law or in equity respecting any patent of invention.” The defendants argued that s 20(2) is not applicable “because the words ‘any patent of invention’ in that section mean a patent of invention obtained in Canada, not simply an invention or a patent of invention obtained in another country” [38, my emphasis]. This seems right to me. As a matter of statutory interpretation, it would appear that “patent of invention” in s 20(2) means the same thing as “letters patent for an invention” under the Patent Act, s 2, and the Patent Act clearly refers to Canadian patents. This is not express, but clear nonetheless from eg s 4(2) which provides that “The Commissioner shall . . . do all acts and things requisite for the granting and issuing of patents of invention.” That provision is evidently not empowering the Commissioner to grant US patents.
Kane J accepted this point:
[59] In order to fall within subsection 20(2), the Plaintiff must be seeking a remedy that
arises from “federal law”. With respect to patents, the only relevant “federal law” is the
Patent Act, which does not create remedies respecting the ownership of unpatented
inventions or foreign patents.
See also [67], emphasizing the need for a Canadian patent.
The defendant argued that s 20(2) was satisfied because the dispute related to “an invention made in Canada and by Canadians.” But s 20(2) does not require merely that the invention is somehow Canadian; it requires that the remedy sought is in respect of a Canadian patent. In this case no remedy was sought relating to any Canadian patent, nor even to a potential Canadian patent application. I should note that the Plaintiff did not actually seek a declaration as to the ownership of the US patent, but rather a declaration that it was the owner of the invention claimed in the corresponding US patent application; an injunction requiring the defendants to convey their interest in the US patent application to the plaintiffs; and injunction prohibiting the defendants from infringing the US patent application [20]. The reference in the pleadings was to the US application, notwithstanding that the US patent had actually been granted: US Patent No. 6,902,385 [18]. Presumably this was because a request for a declaration as to ownership as to the US patent would be self-evidently absurd; but dressing it up as a request for relief related to the US application does not change the substance.
While that point was enough to dispose of the issue, Kane J undertook a more general review of s 20(2), with the key cases being Kellogg, Radio Corporation of America v Philco Corporation (Delaware), [1966] SCR 296, and Cellcor Corp v Canada v Kotacka [1977] 1 FC 227, 27 CPR(2d) 68 (FCA).
I discussed Kellogg in my post on SALT Canada Inc v Baker 2016 FC 830, in which Boswell J refused to make a declaration as to ownership of a granted patent pursuant to s 52 of the Patent Act, on the view that the FC lacks jurisdiction when the essential issue is the ownership based on the interpretation and application of contract law principles. My post suggested that the parties had overlooked Kellogg , which might be read as holding that the statutory grant could be found in s 22(c) of the Exchequer Court Act, which is substantively the same as the current s 20(2) of the Federal Courts Act.
Kane J held that the jurisprudence subsequent to Kellogg reflects a more constrained approach to the interpretation of the Federal Courts Act [69]. Her conclusion is perhaps best summarized by Tremblay-Lamer J in Peak Innovations, 2009 FC 661, [9], quoted with approval at [77]:
Section 20(2) of the Federal Courts Act only establishes jurisdiction for remedies where
jurisdiction for the underlying cause of action is established elsewhere in a statute.
And see [78] reiterating the point. As I understand it, the point is that s 20(2) is effectively solely to enable the Federal Court to grant the appropriate remedy, after substantive jurisdiction has been established under some other provision.
I’m not sure I’m entirely persuaded that is the correct interpretation of s 20(2). The text of s 20(2) states that “The Federal Court has concurrent jurisdiction in all cases. . . in which a remedy is sought. . . respecting any patent of invention .” It does not say, “The Federal Court has concurrent jurisdiction in all cases . . . to grant a remedy . . . respecting any patent of invention.” I would say that on its face s 20(2) gives jurisdiction to the Federal Court (subject to the other branches of the ITO test). That is the reasoning on which the SCC in Kellogg based its interpretation of the provision.
The primary authorities for a more restrictive interpretation of this proposition were Radio Corp and Cellcor. I acknowledge that in writing my post on SALT Canada v Baker 2016 FC 830 I had overlooked both of those cases. And it is also true, as pointed out by Kane J [73], that in Cellcor at [11] the FCA perceived a possible conflict between Radio Corp and Kellogg, and chose to follow Radio Corp. But I’m not convinced there really is a conflict between Radio Corp and Kellogg.
Kellogg was a conflict proceeding in which the main question was which of the parties, Kellogg Co or Kellogg, was the true inventor. The Commissioner had made a decision in favour of Kellogg, pursuant to the procedure set out in then s 44, and that decision had been duly appealed by Kellogg Co to the Exchequer Court pursuant to s 44(8) of the Patent Act. It was undisputed that the Exchequer Court had jurisdiction in that respect. Kellogg Co had also pleaded in the alternative that even if Kellogg were the true inventor, Kellogg was an employee of Kellogg Co. In that case, the remedy sought was that Kellogg Co should be adjudged to be “the owner of the invention made by [Kellogg], and that the respondent should be directed to execute an assignment to the appellant of the entire right, title and interest in and to the invention and the application relating to it” (246). The Exchequer Court had ordered the alternative pleading struck on the basis of lack of jurisdiction, and the SCC reversed, in part because s 20(2) (then s 22(c)) gave jurisdiction because “the remedy sought by the appellant. . . is evidently a remedy in Equity respecting a patent of invention” (250).
Radio Corp also involved a conflict proceeding, and one of the parties, dissatisfied with the Commissioner’s decision, had appealed pursuant to the same provision (by then 45(8)). But in addition to attacking the Commissioner’s decision on the claims which had been found to be in conflict, the appellant had also attacked a variety of other claims in relation to which no conflict had been found (301). The SCC reviewed the history of the relevant provisions, pointing out that under the Act of 1906, conflict proceedings were to be decided by a board of arbitration, while in Hutchins Car Roofing Co ( 1916), 16 Ex CR 391, Cassells J had held that what is now s 20(2) gave the Exchequer Court concurrent jurisdiction with that board (303). The result was that there were two distinct procedures for dealing with conflicting applications. This led to the enactment of the s 44(8) (originally 22(7)), providing for an appeal procedure from a decision of the Commissioner, and, by implication, depriving the Exchequer Court of original jurisdiction in such matters. As the SCC stated (my emphasis):
This subsection [44(8)] recognized the jurisdiction of the Exchequer Court with respect to
conflicting applications for patents, but limited the period during which it might be
exercised.
The important point is, however, that, since 1923, Parliament has made it clear in the
provisions of the various Patent Acts that, notwithstanding the jurisdiction conferred by
the Exchequer Court Act upon the Exchequer Court to deal with conflicting patent
applications, the right to seek redress in that Court by an applicant is governed and
limited by the provisions of the Patent Act respecting conflicting applications. The
conclusion which I draw from the legislative history of the provisions of the Patent Act
respecting conflicting applications is that, although jurisdiction is conferred upon the
Exchequer Court by s. 21 [now 20(2)] of the Exchequer Court Act in cases of conflicting
applications for a patent, the right of a party involved in such a conflict to attack the
patent application of another party is governed by s. 45 and such party is restricted to such
rights as are conferred by that section. As previously stated, it is the opinion of this Court
that proceedings under subs. (8) of that section are limited to the subject matter of the
claims found to be in conflict by the Commissioner.
I read this as saying that Cassells J’s interpretation of s 20(2) was not wrong, and indeed was confirmed by s 44(8), which did not grant the Exchequer Court jurisdiction respecting conflicts, but rather limited the jurisdiction that was already conferred by s 20(2). That is, if the Act did not provide any other method for resolving a conflict, the Federal Court would have jurisdiction under s 20(2), but given that an alternative procedure had been established, s 20(2) could not be used to circumvent that alternative procedure.
A purposive analysis arguably also provides some support for a broad reading of s 20(2). It rounds out the statutory scheme in the same way that s 7(b) of the Trade-marks Act rounds out that Act. S 7(b) allows a trade-mark owner to bring an action in Federal Court based on a registered mark, and plead 7(b) in the alternative, rather than being forced to resort to a new proceeding in provincial superior court if its registration should be held invalid. Similarly, as in Kellogg, s 20(2) allows a plaintiff to raise ownership as an alternative to its claim to inventorship, when the factual issues are closely enmeshed, rather than having to resort to a new proceeding in a different court.
It may also be possible to reconcile Cellcor with Kellogg, but not so readily. In Cellcor the plaintiff sought a declaration that it was the party entitled to apply for a Canadian patent on the basis that it was the inventor of the specified invention, which had been stolen by the defendant, who intended to file an application in Canada. However, it appears that the plaintiff had not actually applied for a Canadian patent. Counsel for the defendant did argue that “the Court cannot exercise its jurisdiction under section 20 unless a right to relief exists by virtue of some other statutory provision,” but it is not clear to me that the Court accepted this proposition. The Court held (my emphasis):
Under the Patent Act, the official who must first decide whether a patent may issue to an
applicant is the Commissioner. The Act does not empower the Courts to give him
directions on the decision he should reach; it is only if he is alleged to have made a wrong
decision that, under the statute, the Courts may be seized of the matter. In my view, it
would be contrary to the scheme of the Patent Act for the Courts to assume the power, in
a case like the present one, to make the declaration sought.
This could be read as saying that the Act provided for a process by which a party may apply for a patent, and to decide who is entitled to the grant of a patent in the case of a dispute, and that specific procedure displaces any general jurisdiction granted by s 20(2). This suggests a distinction between Kellogg and Cellcor on the basis that there is a specific procedure for determining a conflict between inventors, but there is no specific procedure for determining ownership, for example as between an employer and employee.

The Cambridge Handbook of Technical Standardization Law
The Cambridge Handbook of Technical Standardization Law: Competition, Antitrust and
Patents, edited by Professor Jorge Contreras, a leading standards scholar, is now available. Here
is a link to CUP's webpage for the volume, here is a link to the Amazon's page, and here is the
book description:
Tom Cotter and I contributed a chapter titled Judicially Determined FRAND Royalties.
Technical standards are ubiquitous in the modern networked economy. They allow
products made and sold by different vendors to interoperate with little to no consumer
effort and enable new market entrants to innovate on top of established technology
platforms. This groundbreaking volume, edited by Jorge L. Contreras, assesses and
analyzes the legal aspects of technical standards and standardization. Bringing together
more than thirty leading international scholars, advocates, and policymakers, it focuses on
two of the most contentious and critical areas pertaining to standards today in key
jurisdictions around the world: antitrust/competition law and patent law. (A subsequent
volume will focus on international trade, copyright, and administrative law.) This
comprehensive, detailed examination sheds new light on the standards that shape the
global technology marketplace and will serve as an indispensable tool for scholars,
practitioners, judges, and policymakers everywhere.

Uncontested Application to Vary Record of Assignment
Everlight Electronics Co, Ltd v Canada (Attorney General) 2017 FC 1108 Martineau J
2,430,747
Gentex Corp originally obtained the ‘747 patent, which was then assigned to Everlight in a worldwide transaction. Evidence of the transfer of ownership was subsequently filed with the Patent Office. In order to protect confidential information, they had intended to file only a limited appendix to the assignment agreement, but Everlight’s patent agent inadvertently filed the complete agreement.
This application was brought pursuant to s 52 of the Act, which confers a broad jurisdiction on to the Federal Court “to order that any entry in the records of the Patent Office relating to the title to a patent be varied or expunged,” to expunge the complete assignment agreement and replace it with a redacted version. Martineau J granted the application, noting that “[t]he proposed variation will cause no prejudice to third parties, as no outsider is claiming an interest in the Patent, there is no ongoing infringement case, and the rest of the Assignment is immaterial to the public” [5]. This is consistent with a series of cases indicating that the FC will be accommodating in varying records when the interests of third parties are not affected.

No new cases
No new substantive patent / NOC / data protection cases were released last week.
Note that I generally only blog on substantive patent / pharma cases. If you want to keep abreast of all new Canadian decisions, including procedural decisions and copyright and trade-mark cases, I recommend subscribing to the Daily Intellectual Property News service from Alan Macek's IPPractice.
