A patent portfolio analysis Montreal founders and general counsel commission has to answer a question no U.S. audit ever raises: how does this estate live in two patent systems at once? Montreal companies build for a domestic market governed by CIPO and the Federal Court of Canada, but sell into the United States and beyond, so almost every asset has a Canadian family, a U.S. family and a strategy that has to reconcile the two under CUSMA. Layer on Quebec’s aerospace and artificial-intelligence clusters, Canada’s brand-new patent-term-adjustment clock, and the French-language obligations of the Charter of the French Language, and the analysis looks nothing like a Boston or Bay Area review.
Why a patent portfolio analysis Montreal estate spans two patent systems
The single fact that shapes a Montreal estate is dual dependence. The Canadian market is served by the Canadian Intellectual Property Office (CIPO), an agency of Innovation, Science and Economic Development Canada, while the company’s revenue usually depends on the far larger U.S. and European markets. So the first job of the analysis is to line up each Canadian family against its foreign counterparts and confirm they actually claim the same invention, share the same priority date, and have not drifted apart during prosecution.
Canadian prosecution has its own timing traps that a U.S.-trained team will miss. Since the Patent Rules of 30 October 2019, examination must be requested within four years of the filing date (or PCT international filing date), not the old five, and excess-claim fees and continued-examination fees now bite in ways they did not a decade ago. An estate assembled before 2019 and one built after it follow different clocks.
A rigorous patent portfolio analysis Montreal teams rely on therefore starts by reconciling the families across borders: which inventions are protected in Canada only, which have matching U.S. or EPO cases, where a request for examination is still outstanding, and where a divergent claim set has quietly narrowed the real scope of protection on one side of the border.
The Federal Court of Canada and where a Montreal patent is tested
A portfolio is only worth what it can withstand when challenged, so the analysis has to anticipate the forum. In Canada, validity and infringement are federal matters. The Federal Court of Canada holds exclusive jurisdiction over impeachment actions that seek to invalidate a patent under section 60 of the Patent Act, and it hears the overwhelming majority of infringement suits because of its subject-matter expertise. It maintains a registry in Montreal and can conduct proceedings in French, which matters for a Quebec company litigating on home ground.
Provincial superior courts, including the Superior Court of Quebec, share concurrent jurisdiction over infringement, but they can only declare a patent invalid as between the parties before them; they cannot strike it from the register. That distinction changes strategy. If a competitor’s patent needs to be knocked out for good, the fight belongs in the Federal Court, and the portfolio has to be read for that possibility from both sides.
Appeals run to the Federal Court of Appeal and, on leave, to the Supreme Court of Canada. Pharmaceutical estates carry the added layer of the Patented Medicines (Notice of Compliance) Regulations, the Canadian analogue to U.S. Hatch-Waxman litigation, which the analysis flags wherever a regulated product is involved.
Canada’s new patent-term-adjustment clock changes term math
Until recently a Canadian patent expired a clean twenty years from filing, with no equivalent to U.S. patent-term adjustment. That is no longer true, and any current review has to account for it. On 1 January 2025 Canada brought its patent-term-adjustment (PTA) system into force to meet a CUSMA obligation, compensating patentees for unreasonable delay by CIPO.
The eligibility rules are narrow and mechanical. A patent must have a filing date on or after 1 December 2020, and it must have issued after the later of the fifth anniversary of the applicable day and the third anniversary of the date examination was requested. The owner then has three months from grant to apply, pay the prescribed fee, and take on maintenance fees during any additional term. Miss the window and the adjustment is lost.
For a Montreal estate this adds a genuine term-management dimension that did not exist two years ago. We flag every family young enough to qualify, check the issuance dates against the PTA formula, and make sure no eligible additional term slips away because the three-month clock was never diarized.
Aerospace and AI: reading Montreal’s flagship estates
Montreal sits at the centre of two globally significant clusters, and their patents read very differently. Greater Montreal houses roughly 40% of Canada’s aerospace workforce and about three-quarters of the country’s aerospace R&D, anchored by Bombardier, Pratt & Whitney Canada, CAE, Bell Textron Canada and Airbus Canada, which builds the A220. Aerospace estates are dense with mechanical, materials and systems claims, long product lifecycles, and heavy supplier co-development, so joint-ownership and background-IP terms in collaboration agreements are as important as the patents themselves.
The other cluster is artificial intelligence. Mila, the Quebec AI institute co-founded by Yoshua Bengio, anchors around a thousand researchers, and AI now feeds directly into aerospace work such as predictive maintenance and design simulation. AI estates raise questions a mechanical portfolio never does: patentable subject matter for computer-implemented inventions under Canadian practice, whether the real value sits in patents or in trade secrets, and how to protect a model, a training method and an inference pipeline as distinct assets.
A credible patent portfolio analysis Montreal innovators need treats these sectors on their own terms rather than forcing a single template over an aircraft-systems estate and a machine-learning estate that share almost nothing.
University spin-outs and government funding in a Quebec estate
Montreal’s research universities feed a steady stream of spin-outs, and their patents arrive with strings attached, though not the same ones a Boston company inherits. McGill, Université de Montréal, Polytechnique Montréal and Concordia all run active technology-transfer offices, and a company built on their inventions typically holds in-licensed or co-owned patents rather than clean sole title.
Canada has no statutory equivalent of the U.S. Bayh-Dole Act. Rights in publicly funded inventions are governed by contract and by each institution’s IP policy, not by a single federal statute, so the analysis has to read the actual license and sponsored-research agreements rather than assume a standard government-rights framework. Field-of-use limits, improvement-patent ownership and reach-through royalties all live in those documents.
Funding leaves its own fingerprints. The Scientific Research and Experimental Development (SR&ED) tax-credit program and the National Research Council’s IRAP grants support much of the region’s early R&D without claiming ownership, but grant conditions and any provincial or federal co-funding still need checking for reporting or licensing obligations. We map chain of title, co-ownership and every funding condition before any valuation or financing representation is drawn from the estate.
Bill 96 and the French-language overlay on a Montreal IP estate
An IP estate is more than patents, and in Quebec the trademark layer carries an obligation found nowhere else in North America. The Charter of the French Language, expanded by Bill 96, reached a decisive stage on 1 June 2025, and it reshapes how brands attached to a patented product may be used in the province.
The mechanics matter for any Montreal company selling physical goods. On product packaging and public signage, a non-French trademark may stand without a French version only where the mark is registered under the Trademarks Act; an unregistered, common-law mark no longer qualifies for the exception. Generic or descriptive words inside even a registered mark must appear in French, and outdoor commercial signage must give French a “marked predominance,” meaning French text at least twice the size of any other language.
This does not change what a patent claims, but it changes how the surrounding brand assets have to be built and cleared, and it can accelerate a Canadian trademark filing that was previously optional. We flag the interaction so the patent estate and the brand estate are read as one system, not two silos.
How we work with Montreal founders, counsel and R&D leaders
Most Montreal engagements reach us at a decision point: a financing round, a cross-border licensing deal, a potential acquisition by a U.S. or European buyer, or a competitor’s assertion. Each turns on the same foundation, an honest map of what the company owns, controls and is exposed to across both the Canadian and foreign families, delivered fast enough to inform the deal in front of the board.
We work from the patents and published applications, the CIPO and USPTO file histories, license and sponsored-research agreements, collaboration and supply contracts in the aerospace supply chain, and the open literature Montreal’s researchers publish. For diligence we deliver a representations-ready view of the estate; for strategy we deliver a prioritized filing, pruning and licensing plan that respects the four-year examination clock and the PTA windows.
Montreal runs on Eastern Time, and our team coordinates in English and French, so work aligned with Federal Court counsel, university technology-transfer offices, or U.S. and European patent teams moves inside a single business cycle. The goal of every patent portfolio analysis Montreal companies ask us for is a clear, defensible picture of the estate that a board, an investor or a court can act on without a translator.

Frequently Asked Questions
Why is a patent portfolio analysis in Montreal different from one in the United States?
Because a Montreal estate almost always lives in two patent systems at once. The Canadian families are governed by CIPO and the Federal Court of Canada, while the company’s revenue depends on U.S. and European markets, so the analysis has to reconcile the Canadian, U.S. and foreign families under CUSMA, watch the Canadian four-year examination clock, and account for Quebec-specific obligations that no U.S. audit raises.
Which court decides whether a Montreal company’s patent is valid?
The Federal Court of Canada holds exclusive jurisdiction over impeachment actions that seek to invalidate a patent under section 60 of the Patent Act, and it hears most infringement suits. It keeps a registry in Montreal and can proceed in French. The Superior Court of Quebec shares concurrent jurisdiction over infringement but can only find a patent invalid between the parties, not strike it from the register.
Does Canada’s new patent-term-adjustment system affect my portfolio?
It can. Since 1 January 2025 Canada grants patent-term adjustment for unreasonable CIPO delay, but only for patents filed on or after 1 December 2020 that issued after the later of the fifth anniversary of the applicable day and the third anniversary of the examination request. Owners have three months from grant to apply, so we flag every family young enough to qualify before the window closes.
How does Quebec’s Bill 96 affect an IP estate built around patents?
Bill 96 does not change what a patent claims, but it reshapes the brand assets around a patented product. Since 1 June 2025, a non-French trademark may appear on packaging or signage without a French version only if it is registered, generic terms inside a mark must appear in French, and outdoor signs must give French marked predominance. We flag this so the patent and trademark estates are managed together.
