First Application of the New Prior Use Defence
On January 7, 2022, the Federal Court released the public reasons in Kobold Corporation v NCS Multistage Inc.

Partial Summary Judgment Narrows Patent Infringement Case
The recent patent infringement case of Kobold Corporation v NCS Multistage Inc is interesting for two reasons: (1) it shows how a summary judgment motion can advance a case even if certain issues require a full trial; and (2) it is the first time a court has interpreted the defence of prior use since the 2018 amendments to section 56 of the Patent Act. This post considers the use of summary adjudication. Click here to read our companion post which considers the substance of the prior use defence.

Patent Injunctions: “Anything but Unusual”
The popular Canadian pastime of snowmobile litigation has turned up yet another interesting decision (Bombardier Recreational Products Inc v Arctic Cat Inc, 2020 FC 946) – this time on the topic of injunctions. This decision of Justice Roy arose from the moving parties’ attempt to vary an Order issued by the Federal Court in Bombardier Recreational Products Inc v Arctic Cat Inc, 2020 FC 691. As Justice Roy noted, the Order itself was “anything but unusual,” and was representative of injunctions issued in patent cases time and time again. Given this and the existing jurisprudence, it was perhaps a predictable result that the parties were denied any relief.
