LED Patent Invalid for Lack of Enabling Disclosure for All Claimed Permutations

Trustees of Boston University (“BU”) sued Everlight Electronics Co., Ltd., and others (collectively, “Everlight”) for infringement of U.S. Patent No. 5,686,738 (the “738 Patent”). The Federal Circuit reversed the district court ruling that Everlight infringed the ‘738 Patent and failed to prove the patent was invalid, finding that the ‘738 Patent was invalid for lack of enablement… BU argued that the ‘738 Patent did not have to enable growing a monocrystalline layer directly on an amorphous layer so long as the patent enabled the five other permutations in the specification. The Court disagreed, noting that “the specification must enable the full scope of the claimed invention.” While the specification does not have to “expressly spell out every possible iteration of every claim,” it must provide at least a “basic enabling disclosure” for the claimed invention.
