Comcast Corporation et al. v.Entropic Communications LLC
The PTAB found all 82 challenged claims unpatentable by a preponderance of the evidence. The Petitioner successfully argued that Zhang et al. anticipates or renders obvious the claims through various combinations with Reisman, Jackson, and Pandey. Key findings included that Zhang's demultiplexer/selector satisfies the DFE limitation, and 'concurrently' does not require zero delay.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB issued a Final Written Decision finding all 20 claims of U.S. Patent No. 9,210,362 unpatentable. The Petitioner successfully demonstrated that the patent was anticipated or obvious over prior art references, primarily Zhang et al., in combination with other cited references.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast’s rehearing request was partially granted: the PTAB corrected a misstatement in claim 4 but upheld the unpatentability of all 24 challenged claims of Entropic’s broadband OFDMA probe patent.
Microsoft Corporation v.Proxense, LLC
Microsoft filed an IPR petition challenging Proxense's patent 8646042, asserting that the claims are obvious over various prior art references including Giobbi and Broadcom.

Cox Communications, Inc. v.Entropic Communications LLC
Cox Communications' IPR challenge against Entropic Communications regarding cable modem architecture claims 18 and 19 was denied by the PTAB. The Board found that the petitioner failed to meet the legal standard for institution, specifically failing to demonstrate obviousness over various prior art combinations.

Cox Communications' IPR challenge against Entropic Communications regarding network monitoring technology was denied by the PTAB. The Board found insufficient evidence to establish a reasonable likelihood of prevailing on grounds of obviousness over various prior art references.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB denied Comcast Cable Communications' IPR challenge against Entropic Communications' patent covering BCN modulation/bit-loading. The Board found the petitioner failed to demonstrate a reasonable likelihood of prevailing, specifically rejecting the combination of prior art references as obvious.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB denied institution for Comcast's IPR against Entropic, finding insufficient evidence that prior art references (Saey and Gross) disclosed or suggested the claimed composite SNR-related metric. This decision reinforces the burden on petitioners to demonstrate specific support for key limitations in complex technical claims.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications successfully argued that multiple claims in the patent were obvious under 35 U.S.C. § 103, leading to an institution decision by the PTAB. The Board found a reasonable likelihood of prevailing on the assertions of obviousness across various combinations of prior art references.
Comcast Corporation et al. v.Entropic Communications LLC
Comcast Cable Communications successfully secured institution in its IPR challenge against the '690 patent, arguing that various prior art references anticipate or render obvious claims related to channel assessment probes. The Board found a reasonable likelihood of unpatentability for certain claims under 35 U.S.C. § 103, leading to the scheduling of trial.
Microsoft Corporation v.Proxense, LLC
The PTAB found all nine challenged claims unpatentable over the combination of Giobbi ’1573, Giobbi ’1394, and Dua. The Board successfully rejected arguments regarding means-plus-function interpretation, finding key terms like 'PDK' and 'RDC' conveyed sufficient definite structure. This decision represents a significant win for the Petitioner in this IPR proceeding.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB issued a Final Written Decision finding all 20 challenged claims unpatentable under 35 U.S.C. § 103. The Board concluded that the prior art references, particularly Rabenko and Gaspar, rendered the claimed cable modem architecture obvious.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB found that the claims were unpatentable over prior art combinations, specifically rejecting grounds based on Renken's architecture and Aggarwal's limitations. The Board concluded that a Person Having Ordinary Skill in the Art (POSITA) would have been motivated to combine Kamieniecki and Konstantinos for multi-channel functionality.
Comcast Corporation et al. v.Entropic Communications LLC
The PTAB found that several claims of the patent were unpatentable based on anticipation (102) and obviousness (103). Key findings included that Claim 1 was anticipated by IEEE-802.16, and specific combinations of prior art rendered other claims obvious.
Lenovo (United States) Inc. et al. v.Universal Connectivity Technologies Inc.
The PTAB denied institution for a petition challenging Patent No. 7,746,798 B2, citing both procedural factors and significant weaknesses in the merits. The denial was influenced by the proximity of an expected trial date in related litigation to the final decision timeline.
HP Inc. et al. v.Universal Connectivity Technologies Inc.
The PTAB denied the IPR petition filed by HP Inc. and others against Universal Connectivity Technologies Inc., citing that the petitioner's allegations of anticipation and obviousness were not 'particularly strong.' The decision also addressed discretionary denial under § 314(a) based on parallel district court litigation.
HP Inc. et al. v.Universal Connectivity Technologies Inc.
The PTAB denied institution for an IPR petition concerning serial data transmission and symbol encoding (Patent No. 7154905). The Board found that while the petitioner raised obviousness arguments, the merits of the case were not sufficiently strong to overcome procedural hurdles.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC

Samsung Electronics America, Inc. et al. v.Collision Communications, Inc.
Samsung has filed a Request for Director Review challenging the PTAB’s denial of institution of an IPR against Collision Communications’ wireless signaling patent. The petitioner alleges the Board misapplied prior art references and erred in finding a lack of particularity. Samsung seeks reversal of the denial.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC
Lenovo petitions the PTAB Director to overturn a denied institution decision, arguing that the Board misapplied the Hulu "reasonable likelihood" standard and failed to recognize the Dammann paper as prior art. The request seeks institution of an IPR against Intellectual Ventures' OFDM patent.
Samsung Electronics America, Inc. et al. v.Collision Communications, Inc.
The PTAB denied the IPR petition filed by Samsung against Collision Communications' patent covering Multiuser Detection (MUD) technology. The Board found the petitioner failed to demonstrate that the prior art adequately taught the claimed unique signal parameters, leading to a lack of particularity in the arguments.

Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon's IPR petition against Nokia regarding video coding methods was denied by the PTAB, finding that the petitioner failed to demonstrate obviousness over prior art references like Koga and Lin. The Board relied on claim construction distinguishing 'spatial samples' from 'decoded spatial information.'
Cisco Systems, Inc. v.Lionra Technologies Limited
The USPTO Director denied Cisco's request for review of the Final Written Decision in IPR2024‑00734, finding the Board's claim‑construction error harmless. The patent owned by Lionra Technologies remains in force.
