Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00668

Nintendo’s reply argues that the ’648 patent’s preamble is non‑limiting and that the claims are obvious over multiple prior‑art references. It also attacks the patent owner’s § 315(b) time‑bar defense.

Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00668

American GNC requests Director Review of a PTAB decision that found its foundational MEMS‑based IMU patent obvious. The patent owner alleges claim‑construction errors and ignored non‑obviousness evidence, while Nintendo relied on multiple prior‑art references. The petition seeks reversal of the decision.

patent · Jul 3, 2024

Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00667

Nintendo’s reply argues that claims 1 and 3 of American GNC’s MEMS gyroscope patent are obvious over several prior‑art references, supported by extensive expert testimony, and rejects the Patent Owner’s time‑bar and secondary‑consideration defenses.

patent null · Jul 3, 2024

Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00668

Nintendo challenges American GNC's '648 patent, arguing that its inertial measurement unit (IMU) technology is obvious. The petition cites multiple combinations of prior art references to demonstrate the lack of inventive step in claims 1 and 4.

patent null · Jul 3, 2024

Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00667

Nintendo challenges American GNC's angular rate sensor patent (6508122), arguing the claims are obvious over various prior art combinations. The petitioner asserts that combining references like Fujiyoshi with Townsend or Cox renders the claimed technology predictable in the field of MEMS sensors.

patent instituted · Jul 3, 2024

Nintendo Co., Ltd. et al. v.American GNC Corporation

· IPR2024-00668

Nintendo successfully petitioned for institution against American GNC Corporation's patent claims regarding Inertial Measurement Units (IMUs). The Board found a reasonable likelihood of prevailing on at least one claim, despite procedural challenges raised by the Patent Owner.
