Digital Global Systems, Inc. v.DeepSig, Inc.
The Board found several claims of Patent No. 11,018,704 B1 unpatentable over prior art (Jüschke and Holt), primarily based on obviousness under 35 U.S.C. § 103. The decision involved extensive claim construction, notably finding that 'associated with' includes models implemented in a base station and that 'representation of' allows for modeled signals.
Comcast Corporation et al. v.Entropic Communications LLC
The IPR concluded that the Petitioner successfully demonstrated claims 1-18 were unpatentable over prior art references based on obviousness (35 U.S.C. § 103). The Board found a clear motivation to combine Kamieniecki and Konstantinos, overcoming the Patent Owner's arguments regarding redesign complexity.
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.
QUALCOMM INCORPORATED et al. v.COBBLESTONE WIRELESS, LLC,
The PTAB found several claims unpatentable based on obviousness (35 U.S.C. § 103) using various prior art combinations in the field of multi-carrier communication systems. The Board adopted a broad construction of 'information' as 'data,' which was critical to its findings against the Patent Owner.
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.
Cisco Systems, Inc. v.Lionra Technologies Limited
The PTAB found the claims unpatentable under 35 U.S.C. § 103 because they were obvious in light of prior art references (Cornett, Paatela, Nelson, Russell). The Board adopted a construction of 'concurrently writing' that aligned with both parties and district court precedent. Petitioner successfully demonstrated that the combination of disclosures taught all limitations of the claims for high-speed packet processing.
Charter Communications, Inc. v.Iarnach Technologies Limited
The PTAB issued a Final Written Decision finding Claim 5 unpatentable over Bernstein and Tsuge based on obviousness (103). Claims 1-3 and 6-11 were found patentable, despite extensive claim construction disputes regarding 'service auto-configuration method.'
Altice USA, Inc. et al. v.Touchstream Technologies, Inc.
The PTAB issued a Final Written Decision finding claims 22-26 unpatentable under § 103(a) based on combinations of prior art (Aldrey and Mahajan). However, the Board upheld the patentability of claims 1-21, concluding that Calvert did not remedy the necessary 'converting' step.
AT&T Services Inc. et al. v.ASUS Technology Licensing Inc.
AT&T Services Inc. et al.'s IPR challenge against ASUS Technology Licensing Inc. was denied by the PTAB, as all six Fintiv factors weighed in favor of discretionary denial. The Board found that procedural issues, including substantial delays and parallel district court litigation, outweighed the merits of the petitioner's claims regarding beam management technology.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
Amazon successfully petitioned the PTAB to challenge Nokia's video compression patents based on obviousness over prior art references TML6 and Fandrianto. The Board granted institution, finding that the Petitioner met the reasonable likelihood standard for unpatentability. This decision sets a significant precedent in challenging complex technical claims using combined software/hardware disclosures.
Amazon.com, Inc. et al. v.Nokia Technologies Oy
