OptoLum, Inc. v. Cree, Inc., No. 22-1511 (Fed. Cir. June 12, 2023)

From the Opinion

The passage below is extracted verbatim from the opening of the document. It has not been editorially summarized — consult the full opinion for the court's complete reasoning.

OptoLum, Inc. (“Op toLum”) asks us to reverse a dis- trict court decision finding prosecution history disclaimer and estoppel, in addition to excluding certain expert testi- mony. Although there is room for debate regarding the statements made during prosecution that sit at the core of this case, prosecution history disclaimer and estoppel are legal questions on which we agree with the district court. We have considered OptoLum’s remaining arguments but find them unpersuasive. For the foregoing reasons, the de- cision of the district court is affirmed.
