Top five reasons to consider patent litigation in Canada
Canada | 25 June 2018

Canada has historically been a much less active jurisdiction for patent litigation compared to the United States, which can be explained in part by the simple fact that the US market is almost 10 times the size of the Canadian market. However, there are a few notable differences in the procedure and substantive law applied in both jurisdictions that have resulted in Canada becoming an increasingly attractive option for high-stakes patent litigation in recent years.

Federal Court of Appeal upholds interlocutory injunction directed at retailers of set-top boxes
Canada | 03 April 2017

The Federal Court of Appeal recently dismissed an appeal against an interlocutory injunction directed at retailers of set-top boxes that are configured or 'pre-loaded' with various applications that provide their users with unauthorised access to copyrighted television content. In particular, the court held that it was open to the motion judge to infer that purchasers of pre-loaded set-top boxes had an incentive to cancel their subscription with the plaintiffs permanently.

Guidance on entitlement to claim profits in trademark infringement cases
Canada | 05 May 2015

The Federal Court recently confirmed that Imperial Tobacco is entitled to elect an accounting of Philip Morris's profits resulting from the infringement of its rights in the MARLBORO trademark in Canada. This decision will likely become significant precedent for Canadian litigants, as this was the first opportunity in decades for the Federal Court to conduct an in-depth assessment of the issue of entitlement to profits in the trademark context.

Who owns intellectual property generated by employees?
Canada | 07 July 2014

Employees are the source of some of their employer's most valuable intangible assets, including its IP assets. It is paramount for businesses to ensure that they own the IP assets generated by their employees. The rules that apply to employer-employee relationships vary greatly between copyright, patents and industrial designs. Businesses should ensure that contracts include clauses pertaining to the transfer of IP rights.

Product placement as evidence of trademark's fame
Canada | 16 December 2013

The Federal Court recently found the COHIBA trademarks for cigars and cigarillos to be well known and iconic in Canada based on expert evidence establishing use of the brand in media, including film, television, music and print. Trademark owners could now use this evidence to establish a brand's reputation and strengthen its scope of protection.
