International Minerals & Chemicals Corp. v. Golding-Keene Co.
District Court, W.D. New York · 1958-02-20 · cited 7×
This case is a declaratory judgment action in which International Minerals & Chemicals Corp. sought a ruling on the validity and alleged infringement of U.S. Patent No. 2,765,074 owned by defendant Grant S. Diamond, following a cease-and-desist letter from the defendant's patent attorney. The court first confirmed jurisdiction based on the existence of an actual controversy under 28 U.S.C. §§ 2201 and 1338. The central dispute involved the plaintiff's motion under Rule 34 for production of documents related to the patent application's prosecution, including correspondence involving the inventor's counsel and a non-bar member; the defendants withheld them on attorney-client privilege grounds. The court denied the motion, holding that the documents qualified as privileged communications between the client/inventor and counsel (or supervised subordinates) acting in a legal capacity, rather than unprotected technical work product, and were not relevant to the issues at hand.
