Canada top court rules against Pfizer in Viagra patent case

OTTAWA Thu Nov 8, 2012 9:49am EST

OTTAWA Nov 8 (Reuters) - Canada's Supreme Court on Thursday ruled against global drug giant Pfizer Inc, ruling that a patent on its Viagra erectile dysfunction drug was no longer valid.

The court backed an appeal by Israeli-based Teva Pharmaceutical Industries Ltd - the world's largest generic drug maker - which argued Pfizer had not provided enough details when filing its patent, which runs out in 2014 in Canada.
