Jury verdicts of no infringement and invalidity of St. Jude’s patents in St. Jude v. Volcano Corp. C.A. No. 10-631-RGA
On October 19th, 2012, the jury returned a verdict in St. Jude Medical v. Volcano Corp., C.A. No. 10-631-RGA (D. Del.). The case involved patents related to technology for diagnosis of heart disease. The jury unanimously found that St. Jude failed to prove that Volcano infringed St. Jude’s patents (U.S. Patent Nos. 6,112,598 and 6,248,083). The jury also found that claims 1, 2 and 10 of St. Jude’s patents were invalid as anticipated and obvious (U.S. Patent Nos. 5,938,624 and 6,196,980).
On October 25, 2012, after a second trial on Volcano’s counterclaims, the jury returned a verdict that Volcano had failed to prove that St. Jude literally infringed one of its patents (U.S. Patent No. 5,178,159) and that St. Jude infringed three of its patents under the doctrine of equivalents (U.S. Patent Nos. 5,178,159, 5,797,856, and 6,976,965).
