ZTE and Nokia cleared of infringing on InterDigital patents
The Court of Appeals also agreed with the ITC's ruling that the fifth patent was invalid because it was too obvious. Microsoft, which purchased Nokia Devices and Services last year, was happy with the ruling while InterDigital basically shrugged it off. The patent troll said that it was disappointed but had other litigation that it would be focusing on. Huawei was also part of the original litigation, but decided to settle with InterDigital last year.
InterDigital also has separate individual cases against ZTE and Microsoft regarding other patents. Taking place in Delaware District Court, ZTE lost its case in October while the trial involving Microsoft has yet to begin.
