Canadian Federal Court Sets a New Subject-Matter Eligibility Test for Computer-Implemented Inventions


“The new test is predicted to bring clarity to issue-matter perseverance of laptop or computer-implemented innovations in Canada.”

computer-implemented inventions - https://depositphotos.com/55064659/stock-photo-canada-law-concept.htmlClearing the air on labyrinthine topic-issue eligibility standards for laptop or computer-implemented inventions (CIIs), a Canadian Federal Courtroom last month revisited the issue in Benjamin Moore & Co. v. Legal professional Basic of Canada, 2022 FC 923. In its choice, the court, though setting a new exam, rejected, for the second time, a challenge-resolution strategy to declare design followed by the Canadian Intellectual House Business office (CIPO) in analyzing patent applications.

The charm was submitted against selections by the Canadian Commissioner of Patents discovering two Canadian Patent Candidates numbered 2,695,130 and 2,695,146 as patent ineligible underneath sections 2 and 27(8) of the Canadian Patent Act. Intellectual Assets Institute of Canada (“IPIC”), an IP policy advocacy group, intervened in the charm proceedings, affirming that the attraction elevated a fundamental query of Canadian Patent Law.

Assessment Steering for Laptop-Applied Innovations

Section 2 defines “invention” to include things like “any new and useful artwork, process, machine, manufacture or composition of matter.” Subsection 27(8), nevertheless, bars patent grant for a “mere scientific theory or abstract theorem.”

In Totally free Environment Have confidence in v. Electro Sante Inc, 2000 SCC 66, the Supreme Court of Canada clarified that prior to examining topic-subject eligibility, vital components of promises have to be identified by purposively construing claim factors. Aspects pertinent for purposive building include things like noting aspects that have a content result on the invention and the inventor’s intent.

CIPO later on devised a problem-solution approach to assert development, wherein only those people factors in statements that had been required to address the problem determined in the patent software were viewed as crucial. Thereafter, matter-issue evaluation was carried out on vital assert things.

In 2013, CIPO released a Follow Observe, titled “Examination Observe Respecting Laptop or computer-Executed Inventions,” which indicated that if a laptop or computer ingredient is located to be an essential element, the statements would frequently be held as statutory. Nonetheless, if the essential components lack any “physicality”, the promises would be considered non-patentable.

Adhering to a recent Federal Court docket judgment in Choueifaty v. Canada (Legal professional Basic), 2020 FC 837, CIPO released a new Apply Take note in November 2020, titled “Patentable Subject matter-Make a difference under the Patent Act”, which observed that in order to be patent-eligible, the laptop factors should cooperate with other factors of the claimed creation, and that precise invention should really have physical existence or manifest a discernible physical effect.

Patent Purposes

The topic of the current Attraction was two patent purposes, the two titled “Coloration Collection Procedure”, filed by Benjamin Moore & Co., a professional paint production company. The claim factors included color variety strategies involving a mathematical equation that modeled human psychological perceptions to coloration, associating a shade emotion rating to various shades in a databases, and picking shades based mostly on the user’s enter indicating a sought after color emotion level. Both equally apps were filed in July 2007 and posted in January 2009.

Rejection All through Prosecution

Throughout prosecution, both equally patent apps were being turned down by Examiners for encompassing non-statutory topic-make any difference, and not complying with segment 2.

In the Ultimate Business Motion issued in May possibly 2017, the Examiner, on purposively construing the statements, observed that computer factors could not be considered vital. The necessary factors, as noted by the Examiner, provided calculating human psychophysical notion values to coloration factors primarily based on mathematical models, and other elements which are considered as mere mental procedures and patent ineligible. Even so, the Examiner uncovered the patent apps to be novel and non-evident.

Claim Construction by the Patent Appeal Board

The Examiner’s final decision was reviewed by a a few-member Patent Enchantment Board, which incorporated an oral listening to. Through the proceedings, the Applicant relied on Cost-free World Have faith in in emphasizing that computer components brought about materials impact to the claimed invention and have been as a result vital. Further more, the Applicant claimed that the creation solved a technical issue in the field of color science. Having said that, the Applicant conceded that no try was created to clear up a computer issue while retaining the essentiality of laptop aspects.

The Board, on the other hand, concluded that pinpointing a mathematical correlation among shades and human emotive responses to support color selection was not a specialized problem for matter-make a difference concerns, and laptop or computer components had been not essential to the claimed non-technological remedy. The Board cited a Federal Courtroom keeping in Schlumberger Canada Ltd v Commissioner of Patents 1981, FCA 204, that use of computer systems for conducting mathematical investigation of information will not render an creation patentable.

In general, the Board agreed with the Examiner and mentioned that the crucial components of the statements have been directed to mathematical calculations and mental actions. For that reason, the Board rejected both of those programs for becoming patent ineligible.

Existing Appeal Prior to the Federal Court

The Applicant-Appellant moved to the Federal Court towards the Commissioner’s decisions. In this article, the Appellant challenged the Commissioner’s assert building ways of “problem-solution” and finding an “actual invention”. The correct tactic, Appellant argued, would have been figuring out claim features that have a materials result on the creation or components the inventor intended as necessary. By taking away the computer components as non-critical, the Commissioner had incorrectly concluded that the remaining claim elements have been directed to mere mathematical designs and calculations. Appellant contended that use of a computer system was vital to claims for functions these types of as identifying adjacency of colour pairs, storing the colour library, and exhibiting colour choices. This was substantiated by a co-inventor’s declaration, indicating the inventor’s intent on the essentiality of laptop aspects. The Appellant also cited Choueifaty, in which the court held the dilemma-answer strategy to be incorrect at law. On the other hand, the Exercise Observe of November 2020 continued to comply with the challenge-solution solution. Additionally, the Commissioner’s technique of taking into consideration only the novel things in the promises as vital and getting rid of “generic” laptop or computer elements was disputed by the Appellant.

On the Respondent’s aspect, the business of the Lawyer Normal of Canada (AGC) represented the Commissioner. The Respondent at the outset agreed that the Commissioner’s decisions ended up incorrect but sought to remit the applications back to the Commissioner for re-dedication applying a good check for purposive development. Proclaiming it to be a make any difference of administrative legislation, the Respondent argued that judicial intervention would be premature as the Commissioner did not have the option to think about the Appellant’s patent applications less than the new Apply Discover of November 2020. This was due to the fact Commissioner’s choices ended up manufactured just before the Apply Discover was issued. The Respondent emphasized that Commissioner is the appropriate authority obtaining the expertise to complete claim development and assess matter-subject eligibility. Unique judgments were cited wherever the courts showed deference to the Commissioner on technological features of claim building.

On subject-subject eligibility of CIIs, the Respondent contended that an creation should have bodily existence or manifest a discernible outcome. Even further, utilizing a scientific basic principle or mathematical theorem on a generic computer would not render the creation as patentable issue subject.

The Intervenor, IPIC, usually aligned with the Appellant’s place and called CIPO’s tactic to evaluating issue-make a difference patentability incorrect. In addition, CIPO’s tendency of broadly construing the “mere summary theorem” exception was highlighted. It was claimed that even with numerous judicial conclusions to the opposite, CIPO proceeds applying the incorrect issue-answer technique. The Intervenor even further critiqued the problem-remedy approach for becoming detrimental to CIIs, which it said resulted in recurrent rejection of patent applications. Statistics ended up presented that indicated a large quantity of CIIs becoming patented worldwide, when compared to an abysmally low range in Canada. The Intervenor urged a revised framework for subject-make any difference investigation to appropriate this trend. Chorus was added to next Totally free Planet Have faith in in assert development i.e., noting substance impact and inventor’s intent in figuring out regardless of whether a declare ingredient is crucial. The Intervenor disputed CIPO’s observe of excluding personal computer elements as non-important and alleging the remainder of assert as an summary concept and for that reason non-patentable. As a result, the Intervenor asked for the court docket to re-examine the “physicality requirement” in subject-make any difference assessment of CIIs. The Follow See of November 2020 was also disputed for its poor concession to the issue-resolution tactic inspite of the court’s final decision to the contrary in Choueifaty.

Court’s Final decision

Recounting a series of former selections, which include Whirlpool Corp v Camco Inc, 2000 SCC 67, Absolutely free Entire world Believe in, and Canada (Legal professional Common) v Amazon.com, 2011 FCA 328 the courtroom held that none of the decisions counsel a difficulty-alternative solution, and in its place purposive building should be adopted in subject-issue assessment. The court docket re-affirmed the Choueifaty determination, wherever the challenge-alternative solution was discredited, and added that realistic application of scientific concepts and theorems can represent patentable innovations.

The Commissioner’s choices ended up observed in conflict with the Supreme Court’s judgments in Whirlpool and Cost-free Planet Believe in. Particularly, the difficulty-alternative method, taking into consideration only novel facets of claims in subject matter-make any difference investigation, and holding laptop elements as non-essential for not solving a computer system issue, was held as incorrect.

In creating the appropriate legal take a look at for deciding the patentable issue issue, the court docket acknowledged the framework prompt by the Intervenor, finding it compliant with the existing point out of the regulation. The 3-element examination set ahead by the Intervenor and accepted by the courtroom is as follows:

  1. Purposively construe the declare
  2. Request no matter whether the construed claim as a full is composed of only a mere scientific basic principle or summary theorem, or irrespective of whether it contains a sensible application that employs a scientific theory or abstract theorem and
  3. If the construed assert includes a functional software, assess the construed declare for the remaining patentability requirements: statutory groups and judicial exclusions, as well as novelty, obviousness, and utility.

The Appellant’s purposes were being remitted again to CIPO for a new dedication on patentable matter issue based mostly on the lawful examination established by the court docket.


The new examination is envisioned to provide clarity to subject matter-subject willpower of personal computer-executed inventions. In addition to rejecting the use of the challenge-resolution technique in identifying essential assert things, the courtroom has directed that promises should really be assessed as a whole in deciding whether or not any simple software is set ahead. Thus, CIPO’s need that applications involving CIIs will have to present advancements to the functioning of pcs is no lengthier valid. Furthermore, CIPO’s apply of limiting the subject matter-make any difference assessment only to novel elements in statements or its perseverance of “actual invention” has been established aside. Further, a brilliant line to conducting purposive design before novelty evaluation was re-affirmed.

The conclusion is matter to attraction.
