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.

Detailed Summary

Google LLC challenged DH International Ltd.'s patent (9022294) before the PTAB, asserting invalidity under 35 U.S.C. § 103 using prior art references Mooney and Lee. The Board issued an institution decision, confirming that Google established a reasonable likelihood of prevailing in its challenge. Key to the decision was the adoption of Petitioner's broad construction for 'activation cue,' which prevented the Patent Owner from narrowing the claim scope based on non-limiting examples. The arguments centered on whether the claimed features were obvious over Mooney alone (Ground 1) or over the combination of Mooney and Lee (Ground 2), with the Board agreeing that the petition met the threshold for trial.
