Canadian Federal Court docket Units a New Topic-Subject Eligibility Check for Laptop-Applied Innovations

“The brand new check is anticipated to carry readability to subject-matter dedication of computer-implemented innovations in Canada.”

computer-implemented inventions - the air on labyrinthine subject-matter eligibility requirements for computer-implemented innovations (CIIs), a Canadian Federal Court docket final month revisited the problem in Benjamin Moore & Co. v. Lawyer Normal of Canada, 2022 FC 923. In its choice, the courtroom, whilst environment a brand new check, rejected, for the second one time, a problem-solution method to declare building adopted via the Canadian Highbrow Belongings Place of job (CIPO) in inspecting patent programs.

The enchantment used to be filed towards selections via the Canadian Commissioner of Patents discovering two Canadian Patent Candidates numbered 2,695,130 and a couple of,695,146 as patent ineligible beneath sections 2 and 27(8) of the Canadian Patent Act. Highbrow Belongings Institute of Canada (“IPIC”), an IP coverage advocacy group, intervened within the enchantment court cases, asserting that the enchantment raised a elementary query of Canadian Patent Legislation.

Exam Steering for Laptop-Applied Innovations

Segment 2 defines “invention” to incorporate “any new and helpful artwork, procedure, device, manufacture or composition of subject.” Subsection 27(8), on the other hand, bars patent grant for a “mere medical concept or summary theorem.”

In Unfastened International Accept as true with v. Electro Sante Inc, 2000 SCC 66, the Very best Court docket of Canada clarified that sooner than assessing subject-matter eligibility, most important components of claims should be known via purposively construing declare components. Elements related for purposive building come with noting components that experience a subject material impact at the invention and the inventor’s intent.

CIPO later devised a problem-solution method to declare building, during which best the ones components in claims that had been vital to unravel the issue known within the patent utility had been thought to be most important. Thereafter, subject-matter research used to be carried out on most important declare components.

In 2013, CIPO offered a Apply Be aware, titled “Exam Apply Respecting Laptop-Applied Innovations,” which indicated that if a pc element is located to be an most important part, the claims would usually be held as statutory. Alternatively, if the most important components lack any “physicality”, the claims can be deemed non-patentable.

Following a up to date Federal Court docket judgment in Choueifaty v. Canada (Lawyer Normal), 2020 FC 837, CIPO offered a brand new Apply Be aware in November 2020, titled “Patentable Topic-Subject beneath the Patent Act”, which famous that to be able to be patent-eligible, the pc parts should cooperate with different components of the claimed invention, and that precise invention will have to have bodily lifestyles or manifest a discernible bodily impact.

Patent Packages

The topic of the current Enchantment used to be two patent programs, each titled “Colour Variety Device”, filed via Benjamin Moore & Co., a business paint production corporate. The declare components integrated colour variety strategies involving a mathematical equation that modeled human mental perceptions to paint, associating a colour emotion rating to more than a few colours in a database, and settling on colours according to the person’s enter indicating a desired colour emotion stage. Each programs had been filed in July 2007 and revealed in January 2009.

Rejection All through Prosecution

All through prosecution, each patent programs had been rejected via Examiners for encompassing non-statutory subject-matter, and no longer complying with phase 2.

Within the Ultimate Place of job Motion issued in Would possibly 2017, the Examiner, upon purposively construing the claims, famous that pc parts may just no longer be thought to be most important. The most important components, as famous via the Examiner, integrated calculating human psychophysical belief values to paint components according to mathematical fashions, and different components which can be deemed as mere psychological processes and patent ineligible. Alternatively, the Examiner discovered the patent programs to be novel and non-obvious.

Declare Development via the Patent Enchantment Board

The Examiner’s choice used to be reviewed via a three-member Patent Enchantment Board, which integrated an oral listening to. All through the court cases, the Applicant trusted Unfastened International Accept as true with in emphasizing that pc parts led to subject material impact to the claimed invention and had been subsequently most important. Additional, the Applicant claimed that the discovery solved a technical challenge within the box of colour science. Alternatively, the Applicant conceded that no try used to be made to unravel a pc challenge whilst keeping up the essentiality of pc components.

The Board, on the other hand, concluded that figuring out a mathematical correlation between colours and human emotive responses to help colour variety used to be no longer a technical challenge for subject-matter issues, and pc parts weren’t most important to the claimed non-technical answer. The Board cited a Federal Court docket preserving in Schlumberger Canada Ltd v Commissioner of Patents 1981, FCA 204, that use of computer systems for accomplishing mathematical research of knowledge won’t render an invention patentable.

Total, the Board agreed with the Examiner and famous that the most important components of the claims had been directed to mathematical calculations and psychological steps. As a result, the Board rejected each programs for being patent ineligible.

Provide Enchantment Earlier than the Federal Court docket

The Applicant-Appellant moved to the Federal Court docket towards the Commissioner’s selections. Right here, the Appellant challenged the Commissioner’s declare building approaches of “problem-solution” and discovering an “precise invention”. The right kind manner, Appellant argued, would were figuring out declare components that experience a subject material impact at the invention or components the inventor meant as most important. By means of taking out the pc components as non-essential, the Commissioner had incorrectly concluded that the remainder declare components had been directed to mere mathematical fashions and calculations. Appellant contended that use of a pc used to be most important to claims for operations similar to figuring out adjacency of colour pairs, storing the colour library, and showing colour picks. This used to be substantiated via a co-inventor’s declaration, indicating the inventor’s intent at the essentiality of pc components. The Appellant additionally cited Choueifaty, the place the courtroom held the problem-solution method to be wrong at regulation. Alternatively, the Apply Understand of November 2020 endured to practice the problem-solution manner. Moreover, the Commissioner’s manner of bearing in mind best the unconventional components within the claims as most important and taking out “generic” pc parts used to be disputed via the Appellant.

At the Respondent’s aspect, the administrative center of the Lawyer Normal of Canada (AGC) represented the Commissioner. The Respondent on the outset agreed that the Commissioner’s selections had been wrong however sought to remit the programs again to the Commissioner for re-determination the use of a correct check for purposive building. Claiming it to be an issue of administrative regulation, the Respondent argued that judicial intervention can be untimely because the Commissioner didn’t give you the chance to imagine the Appellant’s patent programs beneath the brand new Apply Understand of November 2020. This used to be as a result of Commissioner’s selections had been made sooner than the Apply Understand used to be issued. The Respondent emphasised that Commissioner is the suitable authority having the experience to accomplish declare building and assess subject-matter eligibility. Other judgments had been cited the place the courts confirmed deference to the Commissioner on technical facets of declare building.

On subject-matter eligibility of CIIs, the Respondent contended that an invention should have bodily lifestyles or manifest a discernible impact. Additional, imposing a systematic concept or mathematical theorem on a generic pc would no longer render the discovery as patentable material.

The Intervenor, IPIC, usually aligned with the Appellant’s place and referred to as CIPO’s method to assessing subject-matter patentability fallacious. Moreover, CIPO’s tendency of widely construing the “mere summary theorem” exception used to be highlighted. It used to be claimed that in spite of many judicial selections on the contrary, CIPO continues the use of the wrong problem-solution manner. The Intervenor additional critiqued the problem-solution manner for being destructive to CIIs, which it mentioned led to widespread rejection of patent programs. Statistics had been offered that indicated numerous CIIs being patented international, in comparison to an abysmally low quantity in Canada. The Intervenor advised a revised framework for subject-matter research to right kind this development. Refrain used to be added to following Unfastened International Accept as true with in declare building i.e., noting subject material impact and inventor’s intent in figuring out whether or not a declare part is very important. The Intervenor disputed CIPO’s observe of with the exception of pc components as non-essential and alleging the rest of declare as an summary thought and subsequently non-patentable. As a result, the Intervenor asked the courtroom to re-evaluate the “physicality requirement” in subject-matter research of CIIs. The Apply Understand of November 2020 used to be additionally disputed for its fallacious concession to the problem-solution manner in spite of the courtroom’s choice on the contrary in Choueifaty.

Court docket’s Choice

Recounting a sequence of earlier selections, together with Whirlpool Corp v Camco Inc, 2000 SCC 67, Unfastened International Accept as true with, and Canada (Lawyer Normal) v, 2011 FCA 328 the courtroom held that not one of the selections recommend a problem-solution manner, and as an alternative purposive building should be adopted in subject-matter research. The courtroom re-affirmed the Choueifaty choice, the place the problem-solution manner used to be discredited, and added that sensible utility of medical rules and theorems can represent patentable innovations.

The Commissioner’s selections had been present in struggle with the Very best Court docket’s judgments in Whirlpool and Unfastened International Accept as true with. Particularly, the problem-solution manner, bearing in mind best novel facets of claims in subject-matter research, and preserving pc parts as non-essential for no longer fixing a pc challenge, used to be held as wrong.

In setting up the correct felony check for figuring out the patentable material, the courtroom approved the framework prompt via the Intervenor, discovering it compliant with the present state of the regulation. The 3-part check put ahead via the Intervenor and approved via the courtroom is as follows:

  1. Purposively construe the declare;
  2. Ask whether or not the construed declare as an entire is composed of just a mere medical concept or summary theorem, or whether or not it contains a sensible utility that employs a systematic concept or summary theorem; and
  3. If the construed declare contains a sensible utility, assess the construed declare for the remainder patentability standards: statutory classes and judicial exclusions, in addition to novelty, obviousness, and software.

The Appellant’s programs had been remitted again to CIPO for a brand new dedication on patentable material according to the felony check set via the courtroom.


The brand new check is anticipated to carry readability to subject-matter dedication of computer-implemented innovations. Along with rejecting the usage of the problem-solution manner in figuring out most important declare components, the courtroom has directed that says will have to be assessed as an entire in figuring out whether or not any sensible utility is put ahead. Due to this fact, CIPO’s requirement that programs involving CIIs should supply enhancements to the functioning of computer systems is not legitimate. Moreover, CIPO’s observe of restricting the subject-matter evaluate best to novel components in claims or its dedication of “precise invention” has been put aside. Additional, a vivid line against accomplishing purposive building sooner than novelty research used to be re-affirmed.

The verdict is discipline to enchantment.
