A weekly summary of the precedential patent-related opinions
issued by the Court of Appeals for the Federal Circuit and the
opinions designated precedential or informative by the Patent Trial
and Appeal Board.
Genuine Enabling Technology LLC v. Nintendo Co., et
al., No. 2020-2167 (Fed. Cir. (W.D. Wash.) Apr. 1,
2022). Opinion by Reyna, joined by Newman and Stoll.
Genuine sued Nintendo for infringement of a patent relating to a
new kind of user input device for computing, such as a "voice
mouse." The district court construed the claim term
"input signal" consistent with Nintendo's proposed
construction, and on that basis entered summary judgment of
noninfringement.
In construing the term, the district court relied on arguments
by the inventor, Mr. Nguyen, during prosecution in distinguishing
the "Yollin" reference. The parties agreed that Mr.
Nguyen had disavowed claim scope during prosecution, but they
disputed whether he disavowed claim scope beyond signals
