SAN FRANCISCO — Lawyers for Apple are pursuing an aggressive appellate strategy after losing their bid for sweeping permanent injunctions against Samsung devices a federal jury found violated Apple patents.

In an unusual move, Apple Inc.’s lawyers are asking the U.S. Court of Appeals for the Federal Circuit to bypass review by a three-judge panel and instead have the larger en banc court review the district court’s ruling to clarify what they consider an impossible new standard for obtaining permanent sales bans in patent cases.
