SAN FRANCISCO — A federal judge recently allowed new claims brought in a 2-year-old patent case against a Bay Area medical company. For the defendant, that means it’s time to hire new lawyers.

AngioScore Inc., which makes surgical devices that help doctors clear patients’ blocked arteries, originally filed a suit alleging one claim of patent infringement against competitor TriReme Medical Inc. Late last month, U.S. District Judge Yvonne Gonzalez Rogers, in Oakland, allowed AngioScore to tack on California and Delaware law claims alleging breach of fiduciary duty, aiding and abetting a breach of fiduciary duty and unfair competition.
