In Sonix Technology Co., Ltd. v. Publications International, Ltd., No. 16-1449 (Fed. Cir. Jan. 5, 2017), the Federal Circuit reversed the district court’s decision that the claim term “visually negligible” rendered the claims indefinite.

Sonix brought suit against Publications International, alleging infringement of U.S. Patent No. 7,328,845, which is directed to using a “graphical indicator” to encode information on the surface of an object that can be read using an optical device to output additional information. The asserted claims of the ’845 patent recite that the indicator is “visually negligible.” The district court granted summary judgment, finding the term “visually negligible” indefinite, concluding that it relied on the user’s perception with no objective standard to measure the scope of the term.

UltimatePointer sued Nintendo, alleging infringement of U.S. Patent No. 8,049,729 by Nintendo’s Wii video game system. The district court construed the claim term “handheld device” to require a “direct pointing device” where the cursor shown corresponds to the image on the screen being pointed at. On appeal, the Court affirmed, explaining that “repeated derogatory statements” of indirect pointing devices in the specification indicate that “the criticized technologies were not intended to be within the scope of the claims.” The Court then analyzed the Wii system’s operation and found that, because the pointing correlates to the remote’s position relative to a sensor bar, not the television screen image, the Wii system did not infringe the asserted claims.
