DLA Piper defends St Jude Medical in guidewire patent infringement case

DLA Piper has secured the dismissal of patent infringement claims against subsidiaries of St Jude Medical, a global medical device manufacturer, by device maker Volcano Corp.

On 18 March, Judge Richard G Andrews of the US District Court for the District of Delaware dismissed Volcano’s claims, finding St Jude did not infringe two of Volcano’s patents for miniature guide wires that measure pressure within blood vessels. The decision follows a January claim construction ruling in St Jude’s favour.

In the ruling, Judge Andrews determined that the term ‘flexible element’ in Volcano’s patents referred to a coil. Since St Jude’s accused devices do not include a coil, St Jude was found not to infringe.

John Allcock, global co-chair and US chair of the firm’s intellectual property and technology practice (San Diego), and Stuart E Pollack, partner within the patent litigation group (New York), led the DLA Piper team, which also included partner Tamar Duvdevani (New York) and associates Nika Aldrich and Marc E Miller (both New York).
