Short Summary
Pantech successfully defended the PTAB Director’s discretionary denial of institution in an IPR concerning its LTE/5G patents, arguing the petitioner’s prior art does not teach key claim limitations and that there is no material examiner error.
Detailed Summary
In response to OnePlus Technology’s request for director review of a denied institution under 35 U.S.C. § 314(a), Pantech Corporation argued that the district court is already familiar with the narrow LTE/5G patent family and that the petitioner’s cited prior‑art references—Chandrasekhar‑I, Chandrasekhar‑II, and TI—fail to disclose the essential limitation of a first data field indicating a cycle and offset of muting subframes. The patent owner contended there was no material examiner error, that the petitioner’s arguments amount only to a reasonable‑minds disagreement, and highlighted settled industry expectations that the patents are valid SEPs, which would be disrupted by overturning the denial. The Director’s discretionary denial was upheld, leaving the patents intact.
