Ericsson Inc et al. successfully petitioned to institute IPR against Headwater Partners II LLC's patent (9094868), challenging claims 11-15 on obviousness grounds. The PTAB found a reasonable likelihood that the claimed link quality estimation would have been obvious over Jarvinen and Fox.
Axion Biosystems, Inc. v.Agilent Technologies, Inc.

The PTAB denied the institution of an IPR challenge brought by Solus Advanced Materials Co., Ltd. against SK nexilis Co., Ltd.'s patent, finding insufficient evidence to support obviousness claims. The Board rejected the petitioner's reliance on hindsight bias when attempting to combine prior art references.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
The PTAB denied Solus Advanced Materials' request for rehearing, upholding the initial decision to deny institution of IPR against SK nexilis regarding surface roughness claims. The Board found insufficient evidence of motivation to combine prior art references.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.

Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
Solus Advanced Materials Co., Ltd.'s request for rehearing was denied after the PTAB initially denied institution of IPR against SK nexilis Co., Ltd.'s copper foil patent, upholding the finding that obviousness claims lacked sufficient evidence.
Solus Advanced Materials Co., Ltd. et al. v.SK nexilis Co., Ltd.
Solus Advanced Materials Co., Ltd.'s IPR challenge against SK nexilis Co., Ltd. was denied institution by the PTAB, despite a 'close call' on the merits. The denial hinged primarily on procedural factors related to scheduling and parallel litigation.
SAP America, Inc. et al. v.Cyandia, Inc.
The PTAB instituted the IPR, finding a reasonable likelihood of unpatentability for SAP America against Cyandia. The Board specifically found that key limitations regarding 'determining a notification method' lacked written description support in the original application.
SAP America, Inc. et al. v.Cyandia, Inc.
The PTAB denied SAP's request to institute IPR against Cyandia's patent (8751948), citing copending district court litigation in Texas. The Board determined the overlapping issues made IPR redundant.
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
Samsung Electronics successfully secured institution at the PTAB for its IPR against Harbor Island Dynamic's patent 9245826. The Board found a reasonable likelihood of prevailing on multiple claims based on anticipation and obviousness grounds. This decision sets the stage for a full trial regarding semiconductor device technology.
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
Samsung Electronics successfully pushed through the institution phase of its IPR against Harbor Island Dynamic, LLC regarding semiconductor fabrication technology. The Board found a reasonable likelihood of unpatentability based on both anticipation (102) and obviousness (103).
Axion Biosystems, Inc. v.Agilent Technologies, Inc.
The PTAB issued a final decision finding the challenged claims unpatentable over Xu-752 and Jones. The Board concluded that the Petitioner failed to demonstrate non-hindsight motivation for combining the references or making the necessary technical modifications, citing lack of support for millisecond time resolution.
SAP America, Inc. et al. v.Cyandia, Inc.
The PTAB found that the challenged claims were unpatentable over prior art combinations under 35 U.S.C. §§ 102 and 103. The Board adopted a broad claim construction, defining 'current state' to include both online and offline device states, which facilitated the finding of obviousness.
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
The PTAB found all twenty challenged claims unpatentable in this IPR proceeding concerning backside metal adhesion. The Board adopted the Patent Owner's position that the claim language does not require strict direct contact for 'on a bottom surface.'
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
The PTAB found all 17 challenged claims unpatentable due to anticipation (102) and obviousness (103). The Board determined that the prior art reference Norström disclosed key features, leading to findings of anticipation for most claims. For others, combinations of Yin and Koshimizu were deemed obvious over the patent.
Deere & Company v.David’s Dozer V-Loc System, Inc. et al.
Deere & Company has filed a Request for Director Review seeking reversal of the PTAB’s denial to institute its IPR challenge to U.S. Patent 10,533,300, which covers skid‑steer automatic grading technology.
