Artificial intelligence (“AI”) is becoming increasingly sophisticated, and the fact that this human invention can now generate its own inventions opens the door to new ways of conceptualizing the notion of “inventor” in patent law. In a recent ruling, the Supreme Court of the United Kingdom (“UK Supreme Court”) however found that an artificial intelligence system cannot be the author of an invention within the meaning of the applicable regulations under which patents are granted. This position is consistent with that of several courts around the world that have already ruled on the issue. But what of Canada, where the courts have yet to address the matter? In this bulletin, we will take a look at the decisions handed down by the UK Supreme Court and its counterparts in other countries before considering Canada’s position on the issue. In Thaler (Appellant) v Comptroller-General of Patents, Designs and Trade Mark,1 the UK Supreme Court ruled that “an inventor must be a person”. Summary of the decision In 2018, Dr. Stephen Thaler filed patent applications for two inventions described as having been generated by an autonomous AI system. The machine in question, DABUS, was therefore designated as the inventor in the applications. Dr. Thaler claimed that, as the owner of DABUS, he was entitled to file patent applications for inventions generated by his machine. That being so, he alleged that he was not required to name a natural person as the inventor. Both the High Court of Justice and the Court of Appeal dismissed Dr. Thaler’s appeal from the decision of the Intellectual Property Office of the United Kingdom not to proceed with the patent applications, in particular because the designated inventor was not valid under the Patents Act 1977. The UK Supreme Court, the country’s final court of appeal, also dismissed Dr. Thaler’s appeal. In a unanimous decision, it concluded that the law is clear in that “an inventor within the meaning of the 1977 Act must be a natural person, and DABUS is not a person at all, let alone a natural person: it is a machine”.2 Although there was no doubt that DABUS had created the inventions in question, that did not mean that the courts could extend the notion of inventor, as defined by law, to include machines. An ongoing trend The UK Supreme Court is not the first to reject Dr. Thaler’s arguments. The United States,3 the European Union4 and Australia5 have adopted similar positions, concluding that only a natural person can qualify as an inventor within the meaning of the legislation applicable in their respective jurisdictions. The UK ruling is part of the Artificial Inventor Project’s cross-border attempt to ensure that the DABUS machine—and AI in general—is recognized as a generative tool capable of generating patent rights for the benefit of AI system owners. To date, only South Africa has issued a patent to Dr. Thaler, naming DABUS as the inventor.6 This country is the exception that proves the rule. It should however be noted that the Companies and Intellectual Property Commission of South Africa does not review applications on their merits. As such, no reason was given for considering AI as the inventor. More recently, in February of this year, the United States Patent and Trademark Office issued a guidance on AI-assisted inventions. The guidance confirms the judicial position and states in particular that “a natural person must have significantly contributed to each claim in a patent application or patent”.7 What about Canada? In 2020, Dr. Thaler also filed a Canadian patent application for inventions generated by DABUS.8 The Canadian Intellectual Property Office (“CIPO”) issued a notice of non-compliance in 2021, establishing its initial position as follows: Because for this application the inventor is a machine and it does not appear possible for a machine to have rights under Canadian law or to transfer those rights to a human, it does not appear this application is compliant with the Patent Act and Rules.9 However, CIPO specified that it was open to receiving the applicant’s arguments on the issue, as follows: Responsive to the compliance notice, the applicant may attempt to comply by submitting a statement on behalf of the Artificial Intelligence (AI) machine and identify, in said statement, himself as the legal representative of the machine.10 To date, CIPO has issued no notice of abandonment and the application remains active. Its status in Canada is therefore unclear. It will be interesting to see whether Dr. Thaler will try to sway the Canadian courts to rule in his favour after many failed attempts in other jurisdictions around the world, and most recently in the UK Supreme Court. At first glance, the Patent Act11 (the “Act”) does not prevent an AI system from being recognized as the inventor of a patentable invention. In fact, the term “inventor” is not defined in the Act. Furthermore, nowhere is it stated that an applicant must be a “person,” nor is there any indication to that effect in the provisions governing the granting of patents. The Patent Rules12 offer no clarification in that regard either. The requirement implied by the clear use of the term “person” in the wording of the relevant sections of the law is important: It was a key consideration that the UK Supreme Court analyzed in Thaler. Case law on the subject is still ambiguous. According to the Supreme Court of Canada, given that the inventor is the person who took part in conceiving the invention, the question to ask is “[W]ho is responsible for the inventive concept?”13 That said, however, we note that the conclusion reached was that a legal person—as opposed to a natural person—cannot be considered an inventor.14 The fact is that the Canadian courts have never had to rule on the specific issue of recognizing AI as an inventor, and until such time as the courts render a decision or the government takes a stance on the matter, the issue will remain unresolved. Conclusion Given that Canadian law is not clear on whether AI can be recognized as an inventor, now would be a good time for Canadian authorities to clarify the issue. As the UK Supreme Court has suggested, the place of AI in patent law is a current societal issue, one that the legislator will ultimately have to settle.15 As such, it is only a matter of time before the Act is amended or CIPO issues a directive. Moreover, in addition to having to decide whether AI legally qualifies as an inventor, Canadian authorities will have to determine whether a person can be granted rights to an invention that was actually created by AI. The question as to whether an AI system owner can hold a patent on an invention generated by their machine was raised in Thaler. Once again, unlike the UK’s patent act,16 our Patent Act does not close the door to such a possibility. Canadian legislation contains no comprehensive list of the categories of persons to whom a patent may be granted, for instance. If we were to rewrite the laws governing intellectual property, given that the main purpose such laws is to encourage innovation and creativity, perhaps a better approach would be to allow AI system owners to hold patent rights rather than recognizing the AI as an inventor. Patent rights are granted on the basis of an implicit understanding: A high level of protection is provided in exchange for sufficient disclosure to enable a person skilled in the art to reproduce an invention. This ensures that society benefits from such inventions and that inventors are rewarded. Needless to say, arguing that machines need such an incentive is difficult. Designating AI as an inventor and granting it rights in that respect is therefore at odds with the very purpose of patent protection. That said, an AI system owner who has invested time and energy in designing their system could be justified in claiming such protection for the inventions that it generates. In such a case and given the current state of the law, the legislator would likely have to intervene. Would this proposed change spur innovation in the field of generative AI? We are collectively investing a huge amount of “human” resources in developing increasingly powerful AI systems. Will there come a time when we can no longer consider that human resources were involved in making AI-generated technologies? Should it come to that, giving preference to AI system owners could become counterproductive. In any event, for the time being, a sensible approach would be to emphasize the role that humans play in AI-assisted inventions, making persons the inventors rather than AI. As concerns inventions conceived entirely by an AI system, trade secret protection may be a more suitable solution.

Last Wednesday (July 26), the Federal Court of Appeal (FCA) handed down its highly awaited decision on the patentability of computer-implemented inventions (software patents). In Canada (Attorney General) v. Benjamin Moore & Co. (2023 CAF 168), the FCA rejected the test proposed by the Intellectual Property Institute of Canada (IPIC) in the first instance decision, Benjamin Moore & Co. c. Canada. On the one hand, according to the Court of Appeal, Justice Gagné of the Federal Court should not have included IPIC’s proposed framework in the operative provisions of her ruling because it was not requested in the parties’ application. In addition, in the FCA’s opinion, establishing an analytical framework for software patents would be premature, as many issues have yet to be properly considered by any court in Canada. So, back to square one? Not quite… Review of the facts of the Benjamin Moore case (2022) This FCA decision—the most recent in the Canadian software patent saga—establishes a modicum of order against a highly unusual backdrop. For those of you who have just joined the debate, here is a short summary of the facts. As part of a national initiative, Benjamin Moore applied for two software patents in Canada in 2010.1 The software in question was designed to help users navigate a colour bank based on criteria such as “emotion” and “harmony”. In October 2014, both applications were rejected on the grounds that they dealt with non-patentable subject matter. By applying an analytical framework that the Canadian Intellectual Property Office (CIPO) referred to as a “problem-solution” approach, the CIPO examiner concluded that the inventions in question were akin to applying mathematical formulas to a database. Mathematical formulas, however, are not patentable. In May 2020, the Patent Appeal Board confirmed CIPO’s decision. In November 2020, Benjamin Moore appealed the decision before the Federal Court. In an unusual move, during a hearing on March 30, 2022, the Attorney General immediately acknowledged, in light of the Choueifaty2decision handed down in the interim, that the Commissioner of Patents did not apply the right test and agreed to send the patent applications back for review. In another unusual move, IPIC intervened as a third party on the grounds that the case transcended the parties’ interests because CIPO examiners continued to apply the incorrect software patentability criteria despite repeated criticism by the courts. In so doing, IPIC sought to take the matter further with a view to making the process of granting software patents more predictable, i.e., by setting out the analytical framework that CIPO should apply when examining such cases. In a surprising judgment, Justice Gagné agreed with IPIC’s request: the patent applications were sent back for review based on IPIC’s proposed analytical framework. This declaratory judgment recognized the need for IPIC’s proposed analytical framework. Overnight, this framework became the applicable test for software patents. IPIC’s intervention in Benjamin Moore (2022) or the need to clarify the analytical framework for software patents This was not the first time that IPIC intervened as a third party in a patent case. This type of participation is not always looked on favourably by the courts, particularly with regard to administrative reviews. Moreover, last Friday (July 28), in the case of Taillefer v. Canada,3 Madam Justice McDonald rejected IPIC’s intervention after applying the FCA’s three-step test.4 In her decision, she stated that “to the extent IPIC intends to make submissions on the issue of the proper approach to statutory interpretation, as noted by the Federal Court of Appeal above, such an intervention is inappropriate”. However, a number of patent agents and jurists were delighted in 2022 to see that a more predictable analytical framework had emerged. Clearly, IPIC’s intervention was unusual, but we must revisit the long-running Canadian software patent saga to fully grasp the problem that IPIC was attempting to resolve. It should be noted that the Patent Act remains silent on the topic of software. In it, an invention is defined as “any new and useful art, process, machine, manufacture or composition of matter, or any new and useful improvement in any art, process, machine, manufacture or composition of matter”.5 When software is being patented, we must fall back on a creative description of exactly what is involved, e.g., by describing it as a process or a storage device containing instructions that, once carried out by a computer, produce specific effects. The lack of a proper legislative framework for software leaves a void that the courts must fill by interpreting a law that was last overhauled when Windows 95 was released, along with its 13 floppy disks! In the early 1970s, the Patent and Copyright Office, tasked with examining patent applications, issued a notice for patent professionals explaining that, in its view, software was non-patentable subject matter. However, in the wake of United States v. Waldbaum,6 the Patent Office showed more openness, though it backtracked in 1978 in a bid to harmonize its practices with American and British jurisprudence at the time. In 1981, the Schlumberger case7 became the landmark decision in the area of software patents, with the court ruling that software that relied on the simple execution of a mathematical formula by a computer could not be patented. The Patent Office’s narrow interpretation led to the rejection of large numbers of patent applications. When these cases were appealed, however, most of them were deemed to contain patentable subject matter and were sent back to the examiners for further review. In 1984, CIPO’s directive became more permissive after amendments were made. In 2009, however, the Patent Office rejected an application that had been filed by Amazon, on the grounds that it dealt with non-patentable subject matter. In 2011, the FCA took the Patent Office to task for using a simplified test for evaluating software patents.8 The Patent Office appeared to be applying certain jurisprudence principles too generally, without taking the relevant facts and context into account. Amazon’s patent dealt with the use of cookies to facilitate online purchases without authentication (the famous “one-click” patent). CIPO had difficulty understanding that an invention could be entirely intangible. The patent was finally granted. However, instead of following the FCA’s recommendations, CIPO issued new practice notices in 2012 and 2013 without taking recent jurisprudence into account. The contradictions between the practice notices and the jurisprudence led to unpredictability in the patent review process, during which examiners either adhered to the practice notices or to the jurisprudence. In summer 2020, the Federal Court criticized CIPO in the Choueifaty case,9 explaining that the problem-solution approach described in CIPO’s Manual of Patent Office Practice was not in line with Canadian jurisprudence. In the aftermath of this decision, CIPO modified its practice notices by re-establishing certain principles that had actually been prohibited in the Amazon decision, such as applying principles of section 27(8) of the Patent Act to the notion of an “actual invention”, rather than to “the subject-matter defined by the claim”.10 In short, while the complexity of software grows exponentially, patent law is drawn one decision at a time, while inventors bide their time while grappling with various uncertainties. When IPIC intervened as a third party in the Benjamin Moore case and proposed an analytical framework, the hope was to put an end to 50 years of confusion and unpredictability. Unease in the aftermath of Benjamin Moore (2022) Understandably, this declaratory judgment produced a certain sense of unease among CIPO and the Attorney General, who appealed the matter in fall 2022. Following the Federal Court judgment, CIPO argued that it would be difficult for an examiner to adapt the analytical framework to new situations without risking a contempt of court charge. In addition, since the initial Federal Court application filed by Benjamin Moore was not aimed at obtaining a declaratory judgment, the Attorney General argued that the Court should have adhered to the conclusions sought by Benjamin Moore and the Attorney General. The appeal of the judgment thus focused on whether it was appropriate to issue a declaratory judgment that imposed an analytical framework at the request of a third party. Judicial minimalism — Benjamin Moore (2023) In its 41-page decision handed down on July 26, the FCA reiterated the importance of judicial minimalism while granting the Attorney General’s request to do away with CIPO’s analytical framework. The FCA was unequivocal when it came to including the analytical framework in the mechanism provided for in the lower court ruling: Given the lack of a detailed analysis in the FC Decision, the Federal Court’s statement that the current version of MOPOP (as amended by PN2020-04) was irrelevant, and the lack of consideration of all relevant case law, it appears to me that it did little more than “leapfrog” the test to our Court by including it in its judgment instead of its reasons. This exercise, which is quite different from dealing with an issue that was not necessary to determine the appeal before it in obiter, is inappropriate. It does not involve “judicial courage”, as IPIC argued before the Federal Court.11 The FCA also noted that “interveners cannot seek a remedy that was not sought by the parties themselves”.12 Moreover, it stated that “subject to limited exceptions, unless a request to include a particular framework for all computer-implemented inventions in the judgment is a remedy specifically sought in the notice of appeal, it should normally not be considered”.13 Finally, recognizing that the Federal Court does have the power to render declaratory judgments, the FCA noted that even if an application is duly submitted, the court’s “discretion to grant such relief can only be exercised after considering the four-part test set out by the Supreme Court in Ewert v. Canada, 2018 SCC 30 at paragraph 81”.14 Rejection of IPIC’s analytical framework After concluding that she could have rectified the lower court judgment by applying the four-part test, Justice Gauthier held that IPIC’s proposed framework was not adequate and that too many open questions remained that should be analyzed by the courts before any such analytical framework could be imposed. The decision, however, offered some obiter advice by emphasizing the need for patents to add to the body of human knowledge. In this regard, Justice Gauthier wrote “[The] difficulty often lies in determining where the discovery lies, i.e., what new knowledge has been added to human wisdom” and further on, “If the only new knowledge lies in the method itself, it is the method that must be patentable subject matter.” Now that IPIC’s proposed framework was rejected, practitioners will have to fall back on previous decisions to determine whether software is patentable or not. The challenge posed by software patents To understand why CIPO is reluctant to grant software patents at times, we must bear in mind that patents are an exception to the principle of competition. Section 79(5) of Competition Act15 stipulates that exercising a monopoly obtained via a patent or other intellectual property rights is not an anti-competitive act. This privilege, which is granted to the patent-holder for a 20-year period, is designed to provide compensation for the public disclosure of the invention, with potential benefits for society as a whole. The exchange principle is not a recent development: most patent systems in current use were inspired by England’s Statute of Monopolies adopted in 1623. The odds are, however, that the English in the 17th century had no inkling that software applications would ever come into existence. Historically speaking, patented inventions include a tangible component: a machine, a device, the transformation of raw materials, etc. In contrast, unpatented inventions often have an intangible quality, e.g., abstract ideas, mathematical formulas, esthetic considerations, music, etc. When software applications emerged, sophistry became inevitable! Moreover, the notion of “software” itself is hard to define. Software is more than the code used to put together an application (code is copyright-protected, rather than patent-protected). For example, two programmers following the same requirements and specifications will no doubt end up creating different implementations, compiled to different machine instructions. Once these instructions are executed, however, what could be regarded as the same software will emerge. In some ways, patenting a software is akin to patenting certain aspects of its specifications. When we are interested in a mechanical invention and we describe its fundamental components, we realize that it is made up of parts with specific shapes and sizes attached to each other. In contrast, when we break a software application down into its fundamental components, we find various states, thresholds and conditions, which are often described using abstract concepts and mathematical formulas. Unfortunately, these components are dangerously akin to a type of subject matter formally excluded by the Patent Act. Section 27(8) thereof states that “No patent shall be granted for any mere scientific principle or abstract theorem”. This exclusion is designed to ensure that scientific principles remain universally accessible with a view to fostering research and innovation. Therefore, examiners are duty-bound to reject applications that appropriate scientific principles. Depending on whether an examiner focuses on the overall objective of the software or on its individual components, he or she will conclude that it is patentable or not. The difficulty lies in recognizing that, as a general rule, software is more than a set of mathematical formulas. In other words, a much broader view is needed, i.e., one that looks at the forest as a whole, rather than at the individual trees. That is what the Canadian courts have referred to as “purposive construction”. In the Benjamin Moore case, the FCA described purposive construction as a “difficult exercise even for judges”16 and pointed out that if errors do occur, it is because “CIPO and the Commissioner simply did not properly understand all of the subtleties of this difficult exercise”.17 Striking a more positive note in the same paragraph, the judge offered reassurances that the need to apply this method should no longer be problematic because “[as] noted by the AG, the Commissioner did not appeal the decision in Choueifaty, as it did help clear up some misunderstanding in respect of purposive construction […]”. Whether or not we find that reassuring, we have to acknowledge that IPIC’s intervention might not have been the ideal solution to this problem, particularly when we realize that Benjamin Moore was taken hostage by a debate that transcends the private sphere. No doubt, IPIC’s efforts do deserve recognition. But perhaps we should also be asking ourselves whether allowing the courts to draw up an analytical framework one decision at a time is an effective way of establishing software patent law, especially when such a piecemeal manner of progression undoubtedly comes at the expense of the inventors. https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2695130/summary.html and https://www.ic.gc.ca/opic-cipo/cpd/eng/patent/2695146/summary.html Choueifaty v.

Part 1: Four reasons to slow down and four reasons to speed up the process Part 2: Slowing down the process (CA, US, EP, PCT) Part 3: Fast track (CA, US, EP, PCT) Part 1: Why slow down or speed up the process? Slowing down the process Why would anyone want to slow down the process when it already usually takes several years for a patent to be issued? Cash flow Uncertainty for competitors Possibility of changing the scope Possibility of filing a divisional application In some cases, cash flow may justify spreading expenses over a longer period of time. Keeping an application pending longer may also be beneficial from a business perspective. In fact, it could create uncertainty for competitors, who cannot easily determine the scope of the exclusive right that may be granted to you. Moreover, claims are easier to amend while the application is pending. Lastly, filing a divisional application is usually only possible when the parent patent application is still pending. Speeding up the process If slowing down the process is so advantageous, why speed it up? Proof of patentability before expanding the patent application family Monetary valuation or capital raising Proceedings before the courts Strong negotiating position After filing a priority application, the applicant has 12 months to file corresponding applications in other countries. Filing abroad can entail considerable expenses. It may therefore be advantageous to obtain results quickly so you can make the best decision about filing applications in other countries. An issued patent is a far better indication of a technology’s value. This can have a major impact on a company’s valuation and, at the same time, allow for additional capital to be raised. Moreover, filing a patent application will not prevent infringers from marketing your technology; you may only commence proceedings in front of the court with an issued patent. The possibility of instituting legal proceedings could drastically change the tone of negotiations with your competitors—and sometimes your suppliers, too. Strategies and costs Special provisions exist to speed up and slow down the process in many territories. For the purposes of this exercise, we will discuss patent applications in Canada, the United States and Europe. We will also look at international patent applications, namely PCT applications. Part 2: Slowing down the process Canada With regard to slowing down the process, the simplest strategy in Canada is to wait before requesting examination as much as possible. While the provision for this has changed over the years, applicants now have four (4) years from the date of filing a Canadian application to request an examination. For PCT national phase entry, Canada allows an extension of the standard 30-month time limit to up to 42 months under certain conditions. However, examination request dates and maintenance fees remain the same. Therefore, this is beneficial in the short term only. For each examiner’s report (also called office action), it is possible to request an extension of the time limit by two months before the original time limit expires. This request must be accompanied by the late fee and is only accepted under certain conditions. The other option is to not reply to the examiner’s report and to wait until the application is deemed abandoned. The application may then be reinstated by filing a response to the examiner’s report and paying an additional fee. It is important to note that a Canadian application is no longer eligible for accelerated processing if an extension of the time limit was obtained for it or it was reinstated. Furthermore, while an application is abandoned, and even if it is later reinstated, third parties could obtain certain rights to the technology. United States In the United States, an extension of time fee may be paid at the same time as the reply to an examiner’s report is filed. However, the maximum time limit must not exceed six (6) months. It is also possible to file a request (or petition) for the suspension of the time limit for replying to an examiner’s report (by paying the relevant fee, of course). This request is only acceptable under certain conditions and cannot exceed six (6) months. Similarly, a request may be filed to defer the examination of the application, which may delay examination by up to three (3) years after the priority date. Once again, certain conditions must be met and there is a fee to pay. Europe As is the case for Canada, for each examiner’s report, a request can be made to extend the time limit by two (2) months before the original time limit expires. However, unlike in Canada, there are no fees or conditions for this request to be accepted. The other option is to not reply to the examiner’s report and to let the application lapse. The application may then be reinstated by filing a response to the examiner’s report and paying an additional fee. As for the 10-day rule, it will continue to apply until November 2023. This rule, which was established at a time when communications were still sent by mail, provides that a dated communication is deemed to have been delivered ten (10) days after the date of the document—the time limit is therefore automatically extended by ten (10) days. All things considered, the elimination of this rule is a plus in helping prevent various communication problems. PCT When it comes to slowing things down, the PCT application itself may be used to slow down the process. In fact, the international patent application system provides allows a decision on international applications to be made as late as 30 months from the priority date. The PCT system is based more on the reservation of rights than on slowing down the process. Nevertheless, both from cash flow and filing strategy standpoints, the longer time limit for making decisions may be beneficial. Summary–slowing down the process CA: Postpone filing the Canadian application or entering the national phase. Push back the examination request. Apply for an extension of the time limit. Do not respond, then apply for reinstatement. US: Pay time limit extension fees. Submit a request to suspend processing. Submit a request to defer the examination. EP: Apply for an extension of the time limit. Apply the 10-day rule. Do not respond, then pay the fees to have the application reinstated. PCT: Take advantage of the 30-to-42-month extension for each country. Part 3: Fast track Canada Of course, the best way to speed up the process is to request an examination as soon as possible and, above all, not put off replying to the examiner’s reports received. After requesting an examination and before receiving the first examiner’s report, it is possible to request that the application be processed expeditiously. The request requires that the Canadian application be published and it may be subject to a number of conditions. An applicant whose rights may be prejudiced by the examination time limit can pay an additional fee to expedite the process. When a patent application relates to so-called green technology or the COVID-19 pandemic, the notion of prejudice does not apply and no fee is due. Speeding up the process is also possible by taking advantage of the outcome of a corresponding application in another jurisdiction deemed credible by the Canadian Patent Office (e.g., Europe, United States, Japan, etc.). This is referred to as a PPH (patent prosecution highway) request (the French translation by “autoroute de traitement des demandes de brevet”, while quite accurate, is rarely used). United States Those who have the means to do so may pay an acceleration fee when filing the application in the US. The intent is then to complete the entire process within 12 months. The ability of the US Patent Office to meet the expectation is also taken into consideration before accepting the request. Special treatment may also be requested for a patent application where the health or age of one of the inventors warrants this. Such a request may also be made when the technology in the patent application is “green” or relates to “counterterrorism.” The US also takes part in the PPH system, and the decision made regarding a corresponding application in another jurisdiction can also help speed up the process. Evidently, it is important not to delay replying to the examiner’s reports received, no matter how else you may choose to accelerate the process. Europe The European Patent Office accepts PPH requests and also offers the “PACE” programme, which helps speed up processing times (search and/or examination) without any fees or specific conditions other than responding to examiner’s reports in a timely manner. The European Patent Office’s ability to handle the requests is also taken into account. PCT Quickly completing national phase entries (i.e., well before the 30-month time limit) makes it possible to proceed faster with the substantive examination in each jurisdiction. During the international phase of the PCT, attempts can be made to move the process along before entering the national phase. This procedure often dubbed as a “Chapter II request” does not guarantee that time will be saved, but certain questions may be anticipated thus avoid multiple delays in front of different examiners. Summary – speeding up the process CA: File the Canadian application or enter the national phase as soon as possible. Make the examination request as soon as possible.
