Google LLC v.DH International Ltd.
DH International Ltd. seeks Director Review of the PTAB’s decision to institute an IPR against its Bluetooth‑related patent, arguing the Board used an improper subjective standard and that the cited prior art does not teach the required activation cue.
Google LLC v.DH International Ltd.
The patent owner seeks Director Review, asserting the PTAB misinterpreted “close proximity” and the activation cue in its Bluetooth‑based data‑exchange patent. It claims the Board’s reliance on Mooney and Lee references is unsupported, urging reversal of the unpatentability finding for claims 1‑20.

Google has filed an IPR petition seeking to invalidate all 20 claims of DH International’s ’294 patent covering multimode cellular phone data switching, arguing that Mooney and Lee disclose the same features and that discretionary denial is unwarranted.
Google LLC v.DH International Ltd.
Google LLC successfully petitioned the PTAB to challenge DH International Ltd.'s patentability, leading the Board to institute IPR proceedings on all 20 claims. The Board adopted a broad construction of 'activation cue' favorable to Google and found that the Petitioner met the standard for institution based on obviousness grounds over prior art references Mooney and Lee.
Google LLC v.DH International Ltd.
The PTAB issued a Final Written Decision finding that all 20 claims of the '294 patent were unpatentable over prior art references Mooney and Lee. The Board successfully construed key terms like 'activation cue' functionally, agreeing that a quality Bluetooth signal satisfies this requirement.

Charter Communications, Inc. et al. v.Adaptive Spectrum and Signal Alignment, Inc.
The PTAB denied Charter Communications' request to institute IPR against Adaptive Spectrum regarding patent 10848398. The denial was based on the proximity of a related district court trial date and the perceived lack of strong merits.
