Huawei sued T-Mobile for infringing 13 Huawei patents.
[
On January 15, 2016, Huawei filed four lawsuits against T-Mobile, alleging infringement
of thirteen patents.1 T-Mobile answered with affirmative defenses and counterclaims based on a
number of different legal theories. While the legal theories vary, T-Mobile’s central complaint is
that Huawei did not honor its commitments to ETSI because Huawei (1) failed to comply with the
obligation to reasonably and timely disclose patents (referred to in the ETSI Policy as “IPR,” or
“intellectual property right”) that might be essential to the Long-Term Evolution (LTE) standard,
and (2) failed to offer T-Mobile licenses to the patents-in-suit on fair, reasonable, and
nondiscriminatory (FRAND) terms. See Ans. at 12-50, Dkt. 106. ]
