Panel Rejects Eli Lilly Claim Over Canadian Patent Law, Orders Company to Pay Millions in Costs - Michael Geist
In the early 1990s, Eli Lilly applied for patent protection in Canada for two chemical compounds, olanzapine and atomoxetine. The company had already obtained patents over the compounds, but asserted that it had evidence to support new uses for the compounds that merited further protection. The Canadian patent office granted the patents based on the content in the applications, but they remained subject to challenge. Both patents ultimately were challenged on the grounds that there was insufficient evidence at the time of the applications to support the company's claims. The Federal Court of Canada agreed, invalidating both patents. Eli Lilly proceeded to appeal the decision to the Federal Court of Appeal and later to the Supreme Court of Canada. The company lost the appeals, as the courts upheld the decision to invalidate the patents. Under most circumstances, that would conclude the legal story as several Canadian courts reviewed Eli Lilly’s patent applications and ruled that they failed to meet the standards for patentability. Yet in June 2013, the company served notice that it planned to use the ISDS provisions in the North American Free Trade Agreement to claim that in light of the decisions, Canada was not compliant with its patent law obligations under the treaty. As compensation, Eli Lilly sought at least $500 million in damages.
