Case Brief Summary & Legal Analysis
tl;dr: A law firm represented a patent holder and an alleged infringer simultaneously. The court held that opinion letters the firm wrote for the infringer, which were adverse to the patent holder, were ethically tainted and could not be used to defend against a willful infringement claim.
Legal Significance: Establishes that an opinion of counsel letter written under an unwaived concurrent conflict of interest is incompetent as a matter of law and cannot be used to rebut a charge of willful patent infringement. The client bears the consequence of its counsel’s ethical breach.
Case Facts & Court Holding
Key Facts & Case Background
Plaintiff Andrew Corp. and Defendant Beverly Manufacturing Co. were both current clients of the law firm Barnes & Thornburg (B&T). B&T represented Andrew in various patent matters. Simultaneously, following a merger with Beverly’s prior firm, B&T began representing Beverly. B&T provided Beverly with three opinion letters concluding that Beverly’s products did not infringe Andrew’s patents. These opinions were directly adverse to B&T’s other client, Andrew. B&T failed to identify this concurrent representation conflict through its internal checks and never sought or obtained conflict waivers from either client. In the subsequent patent infringement lawsuit, Andrew alleged Beverly’s infringement was willful. Beverly sought to introduce the B&T opinion letters as evidence of its good-faith belief of non-infringement, a key defense to willfulness. Andrew moved to disqualify B&T from participating in the case and to exclude the opinion letters, arguing they were the product of a breach of B&T’s fiduciary duty of loyalty to Andrew. Beverly countered that it was an innocent party and should not be penalized for its counsel’s error.
