Patent Life Cycle

I tracked the 42,000 or so patent applications in Canada with a 2001 filing date which all expired by the end of 2021. Only about 17% were still enforceable at expiry but about 30% were in force at the 10 year mark. Overall, about 43% of the original applications (about 18,000) were granted and 118 were litigated in the Federal Court. Continue reading Patent Life Cycle

Patent Decision

The Federal Court issued public reasons for judgment in Rovi Guides v. Videotron, 2022 FC 874. The Court found the four asserted patents invalid for being obvious and/or anticipated and accepted non-infringement defences advanced by the defendant, Videotron. If there had been liability, the Court concluded that the Plaintiff would not have been entitled to an accounting of profits and a design-around cost would have been a reasonable upper bound for any royalty. Videotron was represented by a team from DLA Piper including Bruce Stratton, Alan Macek, Michal Kasprowicz, Gabriella Levkov and Nicole Nazareth.

Assignor Estoppel

Yesterday, the US Supreme Court upheld but limited the doctrine of assignor estoppel for patents in Minerva Surgical Inc. v. Hologic Inc.: “When an assignor warrants that a patent claim is valid, his later denial of validity breaches norms of equitable dealing. … [But an] example of non-contradiction is when an assignment occurs before an inventor can possibly make a warranty of validity as to specific patent claims.”

Foreign Updates

A couple of non-Canadian developments that may be of interest:

  • a majority of the US Supreme Court allowed the registration for the trademark “Booking.com” in the face of arguments that it was generic: “According to the PTO, adding “.com” to a generic term—like adding “Company”—can convey no source-identifying meaning. That premise is faulty, for only one entity can occupy a particular Internet domain name at a time, so a “generic.com” term could convey to consumers an association with a particular website.”
  • the UK Supreme Court in Regeneron Pharmaceuticals Inc v Kymab Ltd considered patent sufficiency: “The disclosure required of the patentee is such as will, coupled with the common general knowledge existing as at the priority date, be sufficient to enable the skilled person to make substantially all the types or embodiments of products within the scope of the claim.”

Innovation Report

The report, “Intellectual Property in Ontario’s Innovation Ecosystem”, was published today by Ontario’s Expert Panel on IP chaired by Jim Balsillie: “… it was clear that the most significant recurring themes revolved around questions of capacity-building in IP education and access to specialized IP legal services as well as the structure and governance of the various ‘public sector’ entities within the ecosystem.” Continue reading Innovation Report
