In February 2013, WilmerHale obtained a significant victory for Becton, Dickinson and Company (BD) in a patent reexamination when the US Patent and Trademark Office (PTO) denied a request for rehearing of an appeal decision in an Inter Partes Reexamination, which had been decided in a manner favorable to BD.

In July 2013, WilmerHale obtained a zero-dollar walk away settlement on behalf of our client Intel in a patent infringement suit brought by Microlinc, a patent troll, in the Eastern District of Texas. After eight years of litigation, four patent reexaminations, four judges, two lawsuits, and one decisive Markman order, we obtained a statement in the stipulation of dismissal that Microlinc was unable to assert any infringement based on the Court’s claim construction.

In July 2013, we obtained a significant victory for Research In Motion (now known as BlackBerry) against non-practicing entity St. Clair Intellectual Property Consultants, Inc. when the Federal Circuit summarily affirmed the district court's summary judgment of non-infringement in RIM's favor. The decision from the Court of Appeals brought to an end a decade-long litigation campaign by St. Clair in which it had won over $100 million in jury verdicts and settlements.

WilmerHale recently achieved a significant victory for client Permobil, Inc. in defense of claims of patent infringement asserted by Pride Mobility Products Corp. in the US District Court for the Eastern District of Pennsylvania.

One of the key assets of the bankrupt company was a series of patents directed to the high-speed delivery of media content over existing cable TV systems... Read More

On April 2012, W.L. Gore & Associates, Inc. filed suit against our client Atrium Medical Corporation in the US District Court for the District of Arizona, asserting three patents related to stents covered with expanded polytetrafluoroethylene (ePTFE).
