Republic of Cyprus (Ministry of Commerce, Industry & Tourism), 2010 FC 719 — Mr. Guay represented the Republic of Cyprus, which appealed from the decision of the Trade-marks Opposition Board dismissing its application to register the certification mark HALLOUMI for use in association with a particular cheese produced in Cyprus.

The Court found that the defendant was merely attempting to avoid dealing with the issue of credibility surrounding its alleged prior art.
Air Canada v. AIS Infonetics Inc., 2009 FC 668 — Mr. Guay represented Air Canada, the defendant in a patent infringement action.

MacLennan v. Gilbert Tech Inc., 2008 FCA 35 — Mr. Guay represented Mr. MacLennan and Quadco Equipment in this second appeal to the Federal Court of Appeal in a patent infringement action brought against Gilbert Tech.
