Lexington Luminance LLC v. Amazon.com Inc., No. 14-1384 (Fed. Cir. Feb. 9, 2015)

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.

Lexington Luminance LLC (“Lexington”) appeals from the decision of the United States District Court for the District of Massachusetts construing c laim 1 of U.S. Patent 6,936,851 B2 (the “’ 851 patent”) and granting judgment on the pleadings that the claim was indefinite. See Lexington Luminance LLC v. Amazon.com Inc. , 6 F. Supp. 3d 179 (D. Mass. 2014) (“ Opinion”). Because we conclude that the district court erred in construing the claim and in holding the claim indefinite , we vacate the judgment of invalidity and remand.
