Arraya — CA2780249: CIPO Refuses Shofar Aviation Sound Patent Application
The Canadian Patent Appeal Board and Commissioner of Patents refused application CA2780249, filed by Christina Arraya and directed to shofar-derived sounds for aircraft and aviation purposes. The refusal rests on four independent grounds: indefinite claims, impermissible new matter, lack of novelty, and obviousness — a comprehensive rejection leaving no viable path to grant without appeal to the Federal Court.
Four-ground refusal signals fundamental patentability failures
Canadian patent application CA2780249, filed by individual applicant Christina Arraya, claims a shofar — the traditional horn instrument — adapted to produce different noises and sounds for aircraft and aviation purposes. The application proceeded to a formal review by the Patent Appeal Board under paragraph 86(7)(c) of the Patent Rules (SOR/2019-251) following rejection under subsection 199(1). The Board comprised three members: Stephen MacNeil, Zoran Novakovic, and Lewis Robart.
On 17 December 2024, the Commissioner of Patents concurred with the Board’s recommendation and refused the application under section 40 of the Patent Act. The refusal is grounded in five distinct deficiencies: Claims 1–3 are indefinite (s.27(4)); the description, claims and drawings contain impermissible new matter (s.38.2); Claims 1–3 lack novelty (s.28.2(1)(b)); Claims 1–3 are obvious (s.28.3(b)); and the application title is non-compliant (s.56(1)(a) of the Patent Rules). Post-hearing proposed amendments were rejected as insufficient to remedy all outstanding defects.
Notably, the Board concluded that even setting aside the new-matter issue entirely, the remaining claims would still fail on novelty and/or obviousness — a belt-and-suspenders finding that forecloses any amendment strategy targeting only the new-matter defect. The applicant retains a six-month window under section 41 of the Patent Act to appeal the Commissioner’s decision to the Federal Court of Canada. The public record does not disclose the prior art relied upon or the specific content of the proposed post-hearing amendments.

Commissioner refuses CA2780249: what each ground means for the applicant
Indefiniteness: Claims 1–3 fail the clarity standard
Under subsection 27(4) of the Canadian Patent Act, claims must distinctly and explicitly define the subject-matter of the invention. The Board found Claims 1–3 indefinite, meaning a skilled reader cannot determine the scope of protection sought with reasonable certainty. Indefiniteness is a standalone ground for refusal and cannot be cured by prior-art arguments alone — the claim language itself must be redrafted.
Claim drafting failureImpermissible new matter taints the entire application
Section 38.2 of the Patent Act prohibits adding subject-matter not reasonably inferable from the original disclosure. The Board found the description, claims, and drawings all contain impermissible new matter — an unusually broad finding. Critically, the Board separately assessed patentability absent the new matter and still found the claims deficient, removing any incentive to simply delete the offending material.
Disclosure integrity issueClaims lack novelty and are obvious even on the best case
Stripped of impermissible new matter, Claims 1–3 were found to anticipate prior art under paragraph 28.2(1)(b) and to have been obvious to a skilled person under paragraph 28.3(b). The Board’s belt-and-suspenders finding — that both novelty and inventive step fail independently — means no claim amendment addressing only form or new matter could rescue the application at examination stage.
Prior art bars grantSix-month Federal Court appeal right preserved under s.41
The Commissioner’s decision triggers a six-month period under section 41 of the Patent Act within which the applicant may appeal to the Federal Court of Canada. Federal Court review of Commissioner refusals is de novo on questions of law but deferential on factual findings. Given the multiplicity of independent grounds — including the substantive novelty and obviousness findings — a successful appeal would face a high evidentiary burden.

Official order — verbatim text
The Commissioner’s decision is notable for its layered, independent findings. Rather than relying on a single dispositive ground, the Board and Commissioner identified five distinct deficiencies spanning claim clarity, disclosure integrity, novelty, and obviousness. The express statement that claims would fail on substantive patentability grounds ‘even if’ new matter were disregarded is a deliberate prosecutorial foreclosure — it signals that the Board assessed the merits fully and is not leaving open an amendment pathway. Under section 41 of the Patent Act, the applicant’s only remaining avenue is a Federal Court appeal within six months of this decision.
CA2780249A1 — Shofar-derived sounds for aircraft and aviation purposes
Canadian patent application CA2780249A1, filed by Christina Arraya, seeks to protect a shofar — a traditional wind instrument made from an animal horn — modified or adapted to produce different noises and sounds specifically for aircraft and aviation purposes. The technical domain sits at the intersection of acoustic signal generation and aviation alerting systems. The application’s claims, limited to Claims 1–3, were found to be indefinite, meaning they failed to recite the subject-matter with sufficient clarity for a skilled reader to determine the metes and bounds of protection sought.
From a commercial perspective, the aviation and aerospace sector relies on standardised acoustic and electronic alerting systems governed by stringent airworthiness regulations. A patent in this space — even a narrow one — could have value in niche applications such as traditional instrument-inspired alert tones or culturally specific signalling devices. However, the Board’s findings of anticipation and obviousness suggest the claimed subject-matter was not sufficiently differentiated from the existing art. Competitors and R&D teams in aviation acoustics should note the prior art landscape implied by these findings when scoping new filing strategies.
Should you run an FTO analysis against CA2780249A1?
Because CA2780249A1 was refused by the Commissioner of Patents and has not been granted, it does not carry enforceable patent rights in Canada as of the decision date. Product and engineering teams developing aircraft acoustic alert systems, cabin notification tones, or aviation sound-signalling devices are not exposed to this specific application as a granted patent. However, the prior art cited implicitly by the Board’s novelty and obviousness findings may itself represent granted patents or publications that warrant independent FTO assessment.
PatSnap Eureka’s FTO Search Agent can map the acoustic aviation signal patent landscape — identifying granted Canadian and international patents covering aircraft alert sounds, horn-based signalling devices, and related technology. Even where a refused application poses no direct threat, understanding what prior art anchored its rejection helps R&D teams identify valid patents in the same space and structure claims that clear the novelty and inventive step hurdles the Board applied here.

What this decision signals for the Canadian patent prosecution landscape
Multi-ground CIPO refusals with independent patentability findings set a high bar for applicants seeking to salvage prosecution through amendment.
Belt-and-suspenders findings limit amendment rescue strategies
When the Patent Appeal Board concludes that claims fail on novelty and obviousness even absent impermissible new matter, applicants cannot recover the application through targeted amendments alone. Practitioners should treat simultaneous new-matter and prior-art findings as a signal to reassess whether the core inventive concept is protectable at all before investing in further prosecution.
Indefiniteness findings at the appeal stage are difficult to reverse
The Board’s indefiniteness ruling under s.27(4) reflects a conclusion that the claims, as drafted, cannot be salvaged by interpretation alone. R&D teams seeking Canadian patent protection for acoustic or signal-based innovations should conduct early claim-drafting reviews to ensure measurable, bounded technical features are recited — particularly where the technology straddles functional and structural language.
Christina v Defendant — key questions answered
CA2780249 was refused on five grounds: Claims 1–3 are indefinite (s.27(4) Patent Act); the description, claims and drawings contain impermissible new matter (s.38.2 Patent Act); Claims 1–3 lack novelty (s.28.2(1)(b)); Claims 1–3 are obvious (s.28.3(b)); and the application title is non-compliant (s.56(1)(a) Patent Rules). The Commissioner concurred with the Patent Appeal Board’s recommendation on 17 December 2024.
Yes. Under section 41 of the Patent Act, the applicant has six months from the Commissioner’s decision dated 17 December 2024 to appeal to the Federal Court of Canada. Federal Court review of Commissioner refusals is available on questions of law, and the court may show deference to the Board’s factual and technical findings. Given the multiplicity of independent grounds — including substantive novelty and obviousness findings — a successful appeal faces a high evidentiary threshold.
The Board explicitly concluded that even if the claims did not contain impermissible new matter, their subject-matter would still lack novelty and/or would have been obvious. This forecloses the strategy of amending the application to delete new matter and then arguing patentability — the Board has already adjudicated patentability on the merits and found it wanting. Any amendment submitted would need to overcome all outstanding defects simultaneously to meet the ‘necessary amendment’ standard under s.86(11) of the Patent Rules.
Section 38.2 of the Patent Act prohibits amendments that add subject-matter not reasonably inferable from the application as originally filed. The Patent Appeal Board found that the description, claims, and drawings of CA2780249 all contained such impermissible additions — an unusually broad finding covering all three application components. New matter introduced after the filing date cannot be relied upon to support patentability and must be removed, though doing so here would not overcome the independent novelty and obviousness findings.
Because CA2780249 was refused and not granted, it confers no enforceable patent rights and does not directly restrict competitors or product developers. However, the prior art underlying the Board’s novelty and obviousness findings may include granted patents in the acoustic aviation signal space. R&D and product teams should conduct an independent FTO analysis against any granted Canadian or international patents covering aircraft alert tones or horn-based signalling devices, rather than relying solely on the non-grant of this application.
