Cantor Index LLC – CA2521159A1 Betting System Patent Application Refused by CIPO
Cantor Index LLC sought Canadian patent protection for a system and method for betting on a subset of participants in an event. The Commissioner of Patents, adopting the Patent Appeal Board’s recommendation, refused all 170 claims on June 5, 2024, finding the subject matter fell outside the statutory definition of invention and was expressly prohibited under the Patent Act.
CIPO refuses 170-claim wagering patent on subject matter grounds
Cantor Index LLC, a financial and wagering technology company, applied for Canadian patent protection under application number CA2521159A1 for a ‘System and Method for Betting on a Subset of Participants in an Event.’ The application proceeded through examination and ultimately reached the Patent Appeal Board, which recommended refusal before the Commissioner of Patents issued a formal decision on June 5, 2024.
The Commissioner adopted the Patent Appeal Board’s recommendation in full, refusing to grant a patent on the basis that claims 1 to 170 encompass subject matter outside the statutory definition of ‘invention’ under section 2 of the Patent Act, and that those same claims define subject matter prohibited by subsection 27(8), which bars patents for rules or methods of games. The refusal applies to all claims on file without exception.
The breadth of the refusal — spanning all 170 claims — suggests that the application’s deficiencies were considered structural rather than correctable by amendment at this stage. The Commissioner’s reference to both section 2 and subsection 27(8) reflects a dual-ground finding that is difficult to overcome on appeal. The public record does not indicate whether Cantor Index LLC intends to pursue the six-month Federal Court appeal window made available under section 41 of the Patent Act.

Closed 5 June 2024 — Commissioner’s refusal issued after Patent Appeal Board review
Commissioner refuses all 170 claims: what the decision means for Cantor Index
Dual statutory bar: ss. 2 and 27(8) Patent Act
Section 2 of Canada’s Patent Act defines ‘invention’ and excludes abstract ideas, mental steps, and disembodied methods. Subsection 27(8) separately prohibits patents for rules or methods of games. The Commissioner applied both grounds, meaning even if the applicant addressed one basis, the other independently bars protection. A dual-ground refusal substantially narrows the scope for a successful Federal Court appeal.
Unpatentable subject matterAll 170 claims refused — Federal Court appeal is the remaining path
Cantor Index LLC loses all Canadian patent protection sought under CA2521159A1. No narrowed claim set was accepted. Under section 41 of the Patent Act, the applicant has six months from June 5, 2024 to appeal to the Federal Court of Canada. Absent a successful appeal, the wagering method described in the application enters the Canadian public domain and cannot be enforced against third parties in Canada.
Six-month appeal windowWagering method patents face a high bar at CIPO
This decision is consistent with CIPO’s and Canadian courts’ restrictive approach to business method and game-rule patents. Applicants in the sports-betting, prediction-market, and financial-wagering technology sectors should treat this outcome as a signal that method claims must demonstrate a concrete technical effect beyond the rules of the game itself to survive Canadian prosecution.
Business method riskCompetitors free to implement subset-betting methods in Canada
With no granted Canadian patent, rival operators and platform developers are not subject to infringement risk from CA2521159A1 in Canada. Companies building event-betting or participant-subset wagering features can proceed without a Canadian FTO obstacle from this application, unless Cantor Index succeeds on appeal and obtains a granted patent with enforceable claims.

Official order — verbatim text
The Commissioner’s decision adopts the Patent Appeal Board’s recommendation verbatim and applies both section 2 and subsection 27(8) as independent grounds of refusal. Invoking subsection 27(8) is particularly significant: it is an absolute statutory prohibition on patents for rules or methods of games, leaving minimal room to distinguish the claimed subject matter through claim amendment alone. The dual-ground structure means a Federal Court appeal must successfully challenge both findings to result in a remitted examination.
CA2521159A1 — System and Method for Betting on a Subset of Event Participants
CA2521159A1 is a Canadian patent application filed by Cantor Index LLC covering a system and method that enables wagers to be placed on a selected subset of participants within a broader event — a structure common in financial spread-betting and sports derivatives markets. The application spans 170 claims, suggesting a broad claim hierarchy intended to capture multiple embodiments of the wagering mechanism. The application was examined under Canada’s Patent Act and ultimately referred to the Patent Appeal Board before the Commissioner issued a final refusal on June 5, 2024.
For the wagering technology and prediction-market sector, CA2521159A1 represents an attempt to patent a core mechanic underpinning modern event-derivative and in-play betting platforms. CIPO’s refusal on subject-matter grounds — rather than prior art — means the technology itself is not novel-challenged; it is simply non-patentable in Canada as drafted. Competitors operating Canadian-facing betting platforms face no infringement exposure from this application, but should monitor any Federal Court appeal that could result in remittal and eventual grant of a narrowed claim set.
Should your team run an FTO against CA2521159A1?
Product and platform teams building event-betting, participant-subset wagering, or in-play derivatives features for Canadian markets should note that CA2521159A1 has been refused and currently confers no patent rights in Canada. However, if Cantor Index pursues a Federal Court appeal and succeeds, the application could be remitted for further examination, and a narrowed granted patent could emerge. Teams with Canadian product roadmaps in wagering technology should track the appeal status of this application.

What this decision signals for wagering and fintech IP in Canada
The Commissioner’s dual-ground refusal reinforces Canada’s restrictive posture on business method and game-rule patents — with direct implications for wagering technology applicants.
Canada applies a strict technical-character test to wagering method patents
CIPO and the Patent Appeal Board consistently require that method claims produce a concrete, tangible technical result beyond executing game rules or business logic. Applicants in the betting and prediction-market space must anchor claims to hardware-level or algorithmic innovations with measurable technical effects to avoid section 2 and 27(8) objections.
A 170-claim refusal signals prosecution strategy failure, not just drafting error
When every claim in a large application is refused on subject-matter grounds, it typically indicates that the core inventive concept — not just peripheral claims — was found non-statutory. Applicants should consider filing continuation strategies with narrower, technically grounded claim sets before reaching the appeal board stage.
Cantor v Defendant — key questions answered
The Commissioner of Patents refused CA2521159A1 on June 5, 2024 because all 170 claims were found to encompass subject matter outside the statutory definition of ‘invention’ under section 2 of Canada’s Patent Act, and to define subject matter prohibited by subsection 27(8), which bars patents for rules or methods of games. Both grounds were applied independently.
Subsection 27(8) of Canada’s Patent Act is an absolute prohibition: no patent may be granted for any mere scheme, rule, or method for doing business, or for a mental act or method of playing a game. Where applied, it cannot be overcome by claim drafting alone — the applicant must demonstrate that the claimed subject matter is more than a game rule or method, which is a high bar for wagering system applications.
Yes. Under section 41 of Canada’s Patent Act, the applicant has six months from the Commissioner’s June 5, 2024 decision to appeal to the Federal Court of Canada. The Federal Court would review the Commissioner’s findings on the section 2 and subsection 27(8) grounds. If successful, the application could be remitted for further examination.
No. A CIPO refusal applies only to Canadian patent rights. Cantor Index LLC may hold or continue to prosecute equivalent patent applications in the United States, Europe, or other jurisdictions. Anyone assessing freedom to operate for subset-betting technology globally should conduct a full international family search before concluding there is no infringement risk.
A refusal covering every claim on file — rather than selective claims — typically indicates that the core inventive concept, not peripheral embodiments, was found non-statutory. It suggests the Patent Appeal Board concluded that no claim in the application could be saved by amendment to conform with the Patent Act’s subject-matter requirements, making the refusal structurally difficult to reverse without a Federal Court ruling on the underlying legal standard.
