A federal judge this week sided with Cordis and fellow plaintiff Wyeth, now part of Pfizer Inc. (NYSE:PFE), transfering a suit seeking to invalidate a patent co-owned by the two companies from the U.S. District Court for Minnesota to New Jersey. The suit was bought by Abbott Laboratories (NYSE:ABT) and Boston Scientific Corp. (NYSE:BSX) as part of their defense against a suit alleging the Xience V and Promus drug-eluting stents infringe on the Cypher stent made by Cordis.
