Dispute Summary
Major wireless carriers, including AT&T, T-Mobile, and Verizon, have filed an IPR petition challenging the validity of a patent related to Radio Link Control (RLC) protocols. Petitioners argue that the challenged claims are anticipated or rendered obvious by existing 3GPP communication standards. The core dispute centers on whether prior art correctly detects protocol errors in wireless transmissions.
