Fenwick & West litigators are hot—and not because it's July. Firm lawyers have racked up a series of back-to-back wins since the summer solstice, most recently on behalf of Amazon before the U.S. Court of Appeals for the Federal Circuit in a patent suit by Innovation Sciences.

Litigators Dave Hadden, Saina Shamilov, Todd Gregorian and Ravi Ranganath  last week convinced the appellate panel to find one patent related to online payments was invalid, and to affirm that Amazon did not infringe another patent.

In late June, Fenwick partners Bryan Kohm and Mike Sacksteder and associate Shannon Turner (along with co-counsel from The Dacus Firm) beat back allegations that their client, semiconductor designer CNEX Labs Inc., stole trade secrets from Huawei Technologies. A federal jury in Texas also sided with CNEX in its counterclaim, though it declined to award damages.
