with the Federal Circuit holding that there was a material factual
issue with respect to infringement under the doctrine of equivalents
(1998 U.S. App. Lexis 10416 (Fed. Cir. 1998))
reversal of summary judgment of patent invalidity, based on the alleged
failure to name an inventor (216 F.3d 1372 (Fed. Cir. 2000)). The
Federal Circuit's decision in this appeal interpreted the second
paragraph of Section 112 of the Patent Act, one of the basic laws
governing the validity of issued patents. Irah Donner, the author of
Patent Prosecution: Practice and Procedure Before the U.S. Patent
Office, has called it a "key" Federal Circuit decision. It has also
been the subject of at least one law review note. See Janet S.

In addition to his litigation
practice, Mr. Weiss prosecutes patent applications for a wide variety
of products, components and technologies, and has particular expertise
in the medical device, mechanical, and business method areas. In 1992,
he appeared before the United States Court of Appeals for the Federal
Circuit, and persuaded the Court to reverse a unanimous decision of the
Board of Patent Appeals and Interferences, denying patent protection to
a football shoe having break-away cleats. (26 U.S.P.Q. 2d 1885 (Fed.
Cir. 1993)). The New York Times profiled that patent, U.S. 5,255,453, as one of its patents of the week. He has also argued before the Board of Patent Appeals and Interferences.
Mr. Weiss also conducts infringement studies, issues patentability opinions, and negotiates licensing agreements.
Mr. Weiss is also the co-inventor of a utility patent directed to a bench press shoulder protection method (U.S. Patent 6,224,518).
