A patent infringement analysis Waterloo companies can litigate on has to be built for where Canadian patent cases are decided — the Federal Court of Canada, the only court that hears infringement and validity together and binds the whole country. Waterloo is Canada’s densest deep-tech cluster: the University of Waterloo and its creator-owned IP policy, the Institute for Quantum Computing and the Perimeter Institute at the heart of “Quantum Valley,” the BlackBerry engineering legacy, OpenText and Communitech. The patents fought over here read on software, wireless and messaging systems, cryptography and quantum hardware, and every case turns on whether an accused product actually practises the claim. PerspireIP builds the claim charts and evidence-of-use that prove, or defeat, that link.
Where a patent infringement analysis Waterloo case is decided
Patent law in Canada is federal, and that one constitutional fact shapes every enforcement decision made in Waterloo. The overwhelming majority of Canadian patent litigation is heard by the Federal Court of Canada, which has national jurisdiction over both infringement and validity. Its judges hear patent cases constantly, its orders run across the entire country, and only the Federal Court can declare a patent invalid in rem so the finding binds the world rather than just the parties in the room.
The distinction that matters for a Waterloo matter is what the provincial court can and cannot do. The Ontario Superior Court of Justice has concurrent jurisdiction to hear a patent infringement claim, but it cannot strike a patent from CIPO’s register on an in rem basis. At most it can decline to enforce a patent between the parties before it. So an accused Waterloo company that wants a weak patent cleared for the whole Canadian market, or a patentee who expects a validity counterattack, almost always ends up in the Federal Court, where infringement and any invalidity counterclaim are tried together.
Appeals run to the Federal Court of Appeal and, with leave, to the Supreme Court of Canada in Ottawa. Because both the infringement read and the validity attack are usually resolved in a single Federal Court action, the evidence that the accused product falls within the claim has to be litigation-ready from the very first pleading.
- Federal Court of Canada — the primary national forum; hears both infringement and validity and is the only court that can invalidate a patent in rem
- Ontario Superior Court of Justice — concurrent jurisdiction over infringement only; it cannot declare a patent invalid against the world
- Federal Court of Appeal — the appellate court for Federal Court patent judgments
- Supreme Court of Canada — the final court of appeal, on leave, in Ottawa
The BlackBerry patents now pointed back at the corridor
No city carries a heavier patent history than Waterloo, because this is where BlackBerry — formerly Research In Motion — built one of the largest wireless portfolios in the world. That legacy is now a live assertion risk for the companies that surround it. In 2023 BlackBerry agreed to sell substantially all of its non-core patents — roughly 32,000 patents and applications in mobile devices, messaging, wireless networking and security — to Malikie Innovations, a subsidiary of the patent-monetization firm Key Patent Innovations. The deal, completed on 11 May 2023, was worth up to US$900 million, with US$170 million paid in cash at closing and the rest tied to future royalties.
Those patents did not disappear when they left Waterloo; they moved into the hands of an entity whose business is licensing and enforcement. For local software, communications and connected-device companies, that means the messaging, authentication and wireless-networking art invented down the road can be asserted against a modern product built anywhere. An infringement or non-infringement read of one of these patents starts with the same discipline: construe the claim, then prove element by element whether the accused system actually practises it.
Waterloo already lived through the cost of getting that analysis wrong. In NTP, Inc. v. Research In Motion, RIM paid US$612.5 million in March 2006 to settle a U.S. patent suit that had threatened to shut the BlackBerry email service down entirely — then one of the largest patent settlements ever recorded. The lesson for every Waterloo firm is the same: a rigorous, evidence-backed infringement analysis is far cheaper than discovering, mid-litigation, that a shipped product reads squarely on someone else’s claim.
Policy 73: why Waterloo founders own the patents they assert
Waterloo’s patent landscape is unusually crowded with startups that own hard IP, and the reason is a single university policy. The University of Waterloo runs a creator-owned intellectual-property regime under Policy 73: unlike most North American universities, which assign inventions to the institution, Waterloo lets the inventor keep full ownership of what they create — faculty, staff, graduate and undergraduate students and postdoctoral fellows alike. It is widely described as the most entrepreneurial university IP policy on the continent, and it has been studied and copied abroad.
The practical effect is that founders walk out of the University of Waterloo owning their patents, and those rights travel straight into the spinouts they build. That is a large part of why the Toronto–Waterloo corridor produces so many patent-holding technology companies — and why so many of them end up on one side or the other of an infringement dispute. A founder-owned patent is an asset to assert against a copyist; it is also exposure, because a fast-scaling startup can unknowingly build a feature that reads on a competitor’s claim.
For an infringement analysis, creator ownership also changes the housekeeping. Chain of title matters: who actually owns the asserted patent, whether it was properly assigned into the operating company, and whether a co-inventor or a sponsored-research contract has a claim to it. We confirm standing and ownership as part of scoping the read, because a claim chart is only as strong as the right to sue behind it.
Quantum Valley, cryptography and infringement that hides in an algorithm
Waterloo has something almost no other city can offer a patent docket: a world-leading quantum cluster. The Institute for Quantum Computing (IQC), founded in 2002 with a landmark donation from BlackBerry co-founder Mike Lazaridis, sits alongside the Perimeter Institute for Theoretical Physics to form what is known locally as “Quantum Valley.” Out of that ecosystem come commercial spinouts such as evolutionQ, co-founded by IQC’s Michele Mosca, and ISARA, a Waterloo post-quantum-cryptography company — both building the quantum-safe encryption the rest of the market will eventually depend on.
Infringement analysis in this field looks nothing like a mechanical teardown. When the asserted claim reads on a cryptographic protocol, a key-exchange scheme or a quantum-control method, the “accused product” is an algorithm, a library or a hardware controller whose behaviour is invisible from the outside. The evidence of use has to be assembled from source code, published protocol specifications, standards-conformance documentation, API behaviour and technical white papers rather than from a photograph of a part.
That is why claim construction has to come first in a Waterloo cryptography or quantum matter. The dispute usually narrows to whether the accused implementation performs the specific claimed step — a particular lattice operation, a specific error-correction routine, a defined signalling sequence — and the analysis stands or falls on mapping that step to real, documented behaviour. We chart these claims against the actual implementation, not against the patent’s high-level summary, so the read survives an expert’s cross-examination.
Claim construction and evidence-of-use for software and hardware
Every patent infringement analysis Waterloo litigators rely on begins with purposive claim construction. Under the Supreme Court’s decisions in Free World Trust v. Électro Santé and Whirlpool Corp. v. Camco, a Canadian court identifies the essential and non-essential elements of a claim as a person skilled in the art would understand them at the publication date. An accused product infringes only if it takes every essential element; a defendant that omits or substitutes an essential element does not, which is why fixing the construction correctly is the whole game.
Canada has been a first-to-file system since 1 October 1989, so the priority date that governs each claim — not who invented first — anchors both the infringement window and any validity attack. For software and computer-implemented claims, subject-matter eligibility also stays live: in Canada (Attorney General) v. Benjamin Moore & Co., 2023 FCA 168, the Federal Court of Appeal sent computer-implemented claims back to CIPO to be assessed on their essential elements, so a fintech, AI or software read has to handle construction, infringement and eligibility together.
With the construction fixed, the work is proving the accused product meets it. Where it is not a literal match, Canadian law still reaches a variant that performs substantially the same function in substantially the same way — the equivalents question folded into purposive construction. The deliverable is an element-by-element claim chart backed by dated, verifiable evidence.
- Element-by-element claim charts mapping every limitation of the asserted claim to the accused product, process or software
- Evidence-of-use built from product teardowns, source-code and model review, protocol and standards documentation, datasheets and public technical literature
- Priority-date analysis fixing the correct governing date for each claim under Canada’s first-to-file rule
- Equivalents analysis where the accused product is not a literal match, argued to Canadian purposive-construction standards
- Non-infringement and invalidity positions for an accused Waterloo company, paired for a Federal Court counterclaim
Discovery in the Federal Court: proving the claim is practised
Canadian patent litigation gives both sides real tools to test an infringement theory, and a claim chart is what makes those tools productive. A Federal Court action moves through documentary discovery, in which each party produces the relevant documents in its possession, and oral discovery — examination for discovery — where a representative of the opposing party answers questions under oath and gives undertakings to follow up. For software and connected-hardware patents, this is often where source code, build records and design documents that reveal how the accused product actually works finally come to light.
Discovery is only as sharp as the claim mapping behind it. An element-by-element chart tells you which document requests and which discovery questions matter, so you gather evidence that proves the specific limitations in dispute instead of fishing across an entire codebase or product line. It also frames the expert evidence — on claim construction, infringement and validity — that ultimately decides the case at trial. A Waterloo software defendant, in particular, benefits from targeting source-code production narrowly to the claimed steps rather than exposing an entire repository.
The same chart that drives discovery becomes the backbone of the trial record. Every reference numeral, every mapped element and every dated exhibit has to line up, because inconsistency between the pleading, the discovery answers and the expert report is exactly what opposing counsel is built to exploit.

Frequently Asked Questions
Which court hears a patent infringement case in Waterloo?
Almost always the Federal Court of Canada, which has national jurisdiction over both infringement and validity and whose orders run across the whole country. The Ontario Superior Court of Justice has concurrent jurisdiction over infringement, but it cannot invalidate a patent against the world — only the Federal Court can grant that in rem relief and order CIPO to amend the register. Because most patentees expect a validity attack and most accused parties want a weak patent cleared for the entire Canadian market, patent litigation involving Waterloo companies is overwhelmingly filed in the Federal Court, where infringement and any invalidity counterclaim are decided together. Appeals go to the Federal Court of Appeal and then, with leave, to the Supreme Court of Canada.
Are the old BlackBerry patents still a litigation risk for Waterloo companies?
Yes. In 2023 BlackBerry sold roughly 32,000 non-core patents and applications — covering mobile devices, messaging, wireless networking and security — to Malikie Innovations, a subsidiary of the patent-monetization firm Key Patent Innovations, in a deal worth up to US$900 million. Those patents are now held by an entity whose business is licensing and enforcement, so the messaging, authentication and wireless art invented in Waterloo can be asserted against modern products anywhere. The region has felt this before: in 2006 Research In Motion paid US$612.5 million to settle NTP’s infringement suit rather than see the BlackBerry service shut down. A careful element-by-element read of any asserted legacy patent is the first line of defence.
How does the University of Waterloo’s Policy 73 affect patent infringement exposure?
Policy 73 is Waterloo’s creator-owned IP regime: inventors keep full ownership of what they create, rather than assigning it to the university. It is widely regarded as the most entrepreneurial university IP policy in North America and is a major reason the Toronto–Waterloo corridor produces so many patent-holding startups. For infringement work it cuts both ways. Founder-owned patents are assets to assert, but a fast-scaling startup can also build a feature that reads on a competitor’s claim. It also makes chain of title important: before a claim chart is worth anything, you have to confirm who owns the asserted patent, whether it was properly assigned into the operating company, and whether any co-inventor or sponsored-research contract has a competing claim.
How do you analyze infringement of a quantum or cryptography patent?
Very differently from a mechanical case. When the claim reads on a cryptographic protocol, a key-exchange scheme or a quantum-control method — the kind of work coming out of Waterloo firms like evolutionQ and ISARA and the Institute for Quantum Computing — the accused product is an algorithm, a software library or a hardware controller whose behaviour is invisible from the outside. Evidence of use has to be assembled from source code, published protocol specifications, standards-conformance documentation, API behaviour and technical white papers. The dispute usually narrows to whether the implementation performs one specific claimed step, so the analysis maps that step to documented behaviour rather than to the patent’s high-level summary, and is built to survive expert cross-examination.
Can the Ontario Superior Court invalidate a patent asserted against a Waterloo company?
Not on an in rem basis. The Ontario Superior Court of Justice can hear a patent infringement claim and can, at most, decline to enforce the patent as between the parties before it. Only the Federal Court of Canada can declare a patent invalid against the world and order CIPO to strike or amend it on the register. That is why an accused Waterloo company that wants a weak patent permanently cleared — not just held off in one dispute — pairs its non-infringement position with a Federal Court impeachment action or invalidity counterclaim, and why validity fights end up in the Federal Court regardless of where the company is based.
Does Canada use a first-to-file system for patents?
Yes. Canada has been first-to-file since 1 October 1989, so the priority date that governs each claim — not who can prove they invented first — anchors both the infringement window and any validity attack. In an infringement analysis this matters because the correct priority date has to be fixed for every asserted claim before the read is meaningful: it defines what counts as the relevant state of the art and frames any invalidity counterclaim that runs alongside the non-infringement case.
What evidence proves that a software or hardware product infringes?
An element-by-element claim chart backed by dated, verifiable proof is the core of any patent infringement analysis Waterloo counsel can rely on. For software that means source-code and model review, API behaviour, build records and public technical documentation; for connected hardware it means teardowns, datasheets and design records; for wireless and messaging patents it means the standard, the chipset and the device behaviour. Canadian construction is purposive, so the chart has to show the accused product takes every essential element of the claim, or a variant that does substantially the same thing in substantially the same way. In a Federal Court action that chart also drives documentary and oral discovery, targeting exactly the limitations in dispute so the decisive evidence is produced rather than buried.
