Recent Trend of Summary Adjudication in IP Cases Stalls

In 2014, the Supreme Court of Canada called for a “culture shift” in how cases are adjudicated, including that summary judgment rules must be interpreted broadly so as to favour proportionality, and fair, timely and just access to courts. In the past 5 years or so, there has been an increase in the disposition of intellectual property cases, including patent cases, in the Federal Court by either summary judgment or summary trial. This trend recently hit a speed bump in The NOCO Company v. Guangzhou Unique Electronics, 2023 FC 208 (“NOCO”) where the Court refused to hear the Defendants’ motion for summary trial on the basis, inter alia, that the issues raised were too numerous and complex, and the evidentiary record did not support the request for summary disposition of the action.

Federal Court of Appeal Confirms Improper Licensing Invalidates Trademark Registration

Licensing trademarks can be beneficial to the trademark owner, and when done correctly it can greatly enhance the rights afforded by the trademark. The key to proper licensing is to ensure the trademark owner exercises control over the character and quality of the licensee’s goods and services that use the trademark. However, the absence of such control can lead to the invalidity of a trademark registration and to the loss of all rights to the trademark. Trademark owners must, therefore, ensure that proper control is in place whenever rights to a trademark are granted to another entity.
