In an important case released today, Teva Canada Ltd. v. Pfizer Canada Inc. 2012 SCC 60, the Supreme Court of Canada ruled that Pfizer’s patent for its popular drug Viagra used for treating erectile dysfunction  was void for not meeting the disclosure requirements in s. 27(3) of the Patent Act.

To satisfy the disclosure requirements, the inventor must disclose his/her invention and describe how it works in the specification.
