You win some, you lose some.

An injunction is essentially a court order which prevents a company from doing something, such as using a trade-mark or a patent.  It can be a very useful tool in intellectual property litigation.  However, as we’ve reviewed in other cases, the test in Canada for obtaining – and maintaining – an injunction is not easy to meet.  The test derives from the Supreme Court decision in RJR-Macdonald Inc. v. Canada (A-G), 1994 CanLII 117 (S.C.C.) .  Two recent Canadian cases illustrate this – one win and one loss:

• Trade-Mark Case: In a recent decision out of Manitoba, the Court decided that the Plaintiffs in Marlborough Hotel Corporation et al. v. First Canadian Hotels & Entertainment Ltd. et al. were entitled to an interlocutory injuction in a battle over the use of the “Skyview Ballroom” mark for hotel services.
• Patent Case: In the recent Alberta decision in Core Laboratories Canada Ltd. v. Lonkar Services Ltd., 2008 ABCA 76 (CanLII), the Court of Appeal overturned an injunction granted by the lower court.  At the lower court, the judge had granted an interim injunction prohibiting the appellants from marketing and providing services which include the use of a gamma ray spectral memory tool. On appeal, the court decided the test had not been met.
