Nobelpharma AB v. Implant Innovations, Inc., 141 F.3d 1059, 1998-1 Trade Cases P 72,100, 46 U.S.P.Q.2d 1097

Facts

Nobelpharma AB and Nobelpharma USA, Inc. (collectively, NP) brought an action against Implant Innovations, Inc. (3I) for infringement of U.S. Patent 4,330,891, which claimed a dental implant. 3I counterclaimed, alleging antitrust violations, arguing that NP was aware the patent was invalid due to failure to disclose the best mode of practicing the invention. The district court ruled the patent invalid and found that 3I did not infringe the patent. NP's motions for judgment as a matter of law (JMOL) and a new trial were denied, leading to NP's appeal.

Issue

Whether the patent was invalid for failure to disclose the best mode of practicing the invention and whether NP was entitled to JMOL or a new trial on the antitrust counterclaim.

Whether the patent was invalid for failure to disclose the best mode of practicing the invention and whether NP was entitled to JMOL or a new trial on the antitrust counterclaim.

Rule

Analysis

The court found that NP's co-inventor, Branemark, had a preferred method of making the claimed dental implant at the time of the patent application but failed to disclose it adequately. This lack of disclosure constituted a violation of the best mode requirement. The court also determined that NP had sufficient opportunity to present evidence against 3I's motion for JMOL but did not do so effectively. Therefore, the court concluded that the patent was invalid as a matter of law.
