The PTAB issued a Final Written Decision rejecting the Petitioner's challenge to U.S. Patent No. 11,014,090 B2 on grounds of obviousness (35 U.S.C. § 103). The Board found that the combination of prior art references did not teach or suggest the specific structural limitations claimed by the patent.
CMS CEPCOR LTD et al. v.Sandvik Intellectual Property AB et al.
The PTAB cancelled original claims (1-10) but granted substitute claims (11-19) after a Patent Owner's Motion to Amend. The Board found the Petitioner failed to demonstrate motivation to combine prior art references, thus overcoming obviousness challenges under 35 U.S.C. § 103.

A challenger has filed an Inter Partes Review petition against U.S. Patent No. 10,791,808, owned by The Ridge Wallet LLC.

This challenge targets all 24 claims based on Section 103 (obviousness).
2985 LLC d/b/a Mountain Voyage Company, LLC v.The Ridge Wallet LLC

Shenzhen Waydoo Intelligence Technology Co., Ltd. has filed an IPR petition challenging MHL Custom, Inc.'s hydrofoil watercraft patent (9359044) on grounds of obviousness under 35 U.S.C. §103.

Shenzhen Waydoo Intelligence Technology Co., Ltd. v.MHL Custom, Inc.
The PTAB denied an Inter Partes Review petition against MHL Custom's patent (9586659) filed by Shenzhen Waydoo Intelligence. The denial was based on the petition being time-barred under 35 U.S.C. § 315(b), as Petitioner had already lost related litigation using the same prior art.
Shenzhen Waydoo Intelligence Technology Co., Ltd. v.MHL Custom, Inc.
The PTAB denied institution of IPR for Patent 9,359,044 B2, finding the petition time-barred. The denial followed the rejection of a motion to join because the petitioner had already challenged the patent's validity in district court.

Front Line Medical Technologies Inc. v.Prytime Medical Devices, Inc.
Front Line Medical Technologies has filed a post‑grant review petition seeking cancellation of all ten claims of Prytime’s U.S. Patent 11,857,737 covering low‑profile occlusion balloon catheters. The petition relies on multiple prior‑art references to argue obviousness under 35 U.S.C. § 103 and challenges discretionary denial.
Juniper Networks, Inc. v.Orckit Corporation
Juniper Networks challenges Orckit Corporation's patent via IPR, arguing that the claimed Deep Packet Inspection (DPI) and Software Defined Networking (SDN) methods are obvious. The Petitioner asserts that combining prior art teachings from Lefebvre, Chua, and Rash renders the claims unpatentable under 35 U.S.C. § 103.
Front Line Medical Technologies Inc. v.Prytime Medical Devices, Inc.
The PTAB institution decision found that the petitioner successfully demonstrated a likelihood of prevailing on its obviousness challenges against all ten claims. The Board adopted broad claim constructions for 'proximal hub' and 'flow valve,' finding they could be separate or sub-elements, which supported the grounds of obviousness over various prior art combinations.
Juniper Networks, Inc. v.Orckit Corporation
Juniper Networks' attempt to challenge Orckit's patent was denied by the PTAB. The Board cited General Plastic factors, finding that the claims were materially similar to those previously reviewed and Petitioner had prior knowledge of the asserted prior art.
