Lufthansa Technik AG v. Astronics Advanced Electronic, No. 16-2535 (Fed. Cir. Oct. 19, 2017)

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.

Lufthansa Technik AG appeals from the district court’s grant of summary judgment of invalidity with respect to all claims of U.S. Patent 6,016,016. Because we conclude that the claim term “control means” is indefinite, we affirm on that alternative ground. I Lufthansa asserted the ’016 patent against Astronics Advanced Electronic Systems Corp. and Kid-Systeme Gmbh (collectively, AES) in the District Court for the Western District of Washington. The ’016 patent relates to a voltage supply apparatus for airplane seats.
