AT&T Corp. et al. v.Soto, Alexander et al.
AT&T and the Soto patent owners have settled their dispute over U.S. Patent 8,238,754 covering passive optical network technology. They jointly filed a motion to terminate the IPR, requesting the Board treat the settlement agreement as confidential.
Apple Inc. v.DH International Ltd
The PTAB determined that all 20 challenged claims of the '294 patent were unpatentable under 35 U.S.C. § 103, finding obviousness over combinations of Suga and Gorsuch. The Board successfully rejected the Patent Owner's attempts to narrow key claim terms, upholding the Petitioner's broad interpretation of functional language.
Uber Technologies, Inc. v.Enovsys, LLC
The PTAB denied institution of an IPR challenging claims related to location tracking and wireless systems. The Board found insufficient evidence that the challenged claims would be obvious over the cited prior art, particularly regarding specific limitations like 'tracking period' or 'tracking request.'
Uber Technologies, Inc. v.Envosys, LLC
Uber Technologies' IPR challenge against Envosys' location tracking patent was denied by the PTAB. The Board found that the petitioner failed to meet the burden of showing a reasonable likelihood of prevailing, particularly regarding the scope of geographic notification limitations.
US Conec Ltd. v.Senko Advanced Components, Inc.
Senko Advanced Components argues that US Conec’s IPR petition fails because the cited prior art does not qualify under §102 or disclose the required “slidably received” groove features of claim 1. The patent owner seeks denial of the petition.
US Conec Ltd. v.Senko Advanced Components, Inc.
US Conec Ltd. challenged 17 claims of Senko Advanced Components, Inc.'s patent using grounds of anticipation (102) and obviousness (103). The petitioner argues that the claimed optical fiber connectors are rendered obvious by various combinations of prior art references like Raven, Kuffel, Wong, and Gniadek. The case was dismissed without a final ruling due to a stipulation not to pursue district court grounds.
Meta Platforms, Inc. v.Sitnet, LLC
Meta Platforms challenges Sitnet's patent via an IPR petition, arguing the claims are obvious over combinations of prior art references. The petitioner asserts that known concepts regarding location tracking and message boards render the claimed invention predictable and trivial to implement.
Meta Platforms, Inc. v.Sitnet, LLC
Meta Platforms, Inc. successfully secured institution of its Inter Partes Review against Sitnet's patent 9877345. The Board found that the petitioner met the likelihood standard for obviousness over multiple prior art references (Gage, Mitchell, Shida).
Meta Platforms, Inc. v.Sitnet, LLC
The PTAB issued a Final Written Decision finding that the patent claims were unpatentable by a preponderance of the evidence. The Board found obviousness over single and combined prior art references (Gage/Mitchell) for original claims, and also determined substitute claims failed both 103 and 101 standards.
Comcast Corporation et al. v.Entropic Communications LLC
Entropic Communications seeks Director review of an IPR where the PTAB declared all 18 claims of its cable‑broadband patent unpatentable. The owner alleges procedural abuse, invented arguments, and inconsistent rulings with a related IPR. It requests reversal and termination of the proceeding.
Cox Communications, Inc. v.Entropic Communications LLC
Cox Communications challenged Entropic's '826 Patent in an IPR based on obviousness (103). The petitioner presented multiple grounds combining prior art references like Renken, Maycock, Kidambi, and Zhang. The Board found a reasonable likelihood of prevailing on the grounds of obviousness.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications successfully petitioned to institute IPR against Entropic Communications, LLC regarding claims in patent 8223775. The Board found sufficient evidence of obviousness over various prior art combinations, including Rabenko and Kim, particularly concerning modular hardware upgrades.
Arista Networks, Inc. v.Orckit Corporation
Arista Networks’ request for Director Review of the PTAB’s earlier denial was rejected. The Patent Owner contended that the cited prior art fails to teach the patent’s core limitation of concurrent network‑path failure.
Arista Networks, Inc. v.Orckit Corporation
Arista Networks lost its IPR challenge against Orckit Corporation's '821 Patent, with the PTAB finding no reasonable likelihood that claims 14, 15, and 16 were unpatentable. The Board rejected Petitioner's arguments that prior art combined references taught or suggested the claimed network protection methods.
Arista Networks, Inc. v.Orckit Corporation
The DRP granted Director Review and vacated the Board's denial of institution for Arista Networks against Orckit Corporation. The decision corrected the claim construction and found a reasonable likelihood that Ashwood Smith teaches key limitations.
Motorola Solutions, Inc. v.STA Group, LLC

JACS Solutions challenges Global Tel*Link's '9030292 Patent, asserting that 29 claims are obvious under 35 U.S.C. § 103. The petitioner argues that the claimed features of secure facility monitoring systems are predictable combinations of existing prior art in telecommunications and security technology.
