Spectra-Physics, Inc. v. Coherent, Inc., 827 F. 2d 1524 (Fed. Circ. 1987) US Court of Appeals for the Federal Circuit

Case Description

This case addresses the distinction between the requirements to disclose an invention to the public in general terms (enablement) and the separate requirement to disclose the best mode of carrying out the invention. The district court found the patents at issue invalid due to lack of enablement. The United States Court of Appeals affirmed the judgment of the district court, but on different legal grounds, i.e. due to the failure to disclose the best mode of practicing the invention.
