Ahead of the closures, Apple faces yet more patent litigation in the district. A group of limited liability companies under the Optis Wireless Technology, LLC umbrella filed suit against Apple on Monday in East Texas, accusing the company of infringing on a portfolio of seven patents related to LTE standards.
Optis Wireless and the other plaintiffs named in the complaint appear to be non-practicing entities that aim to generate revenue through patent litigation. These type of companies are commonly referred to as patent trolls.
The complaint, seen by MacRumors, alleges that all LTE-enabled Apple products, including various iPhone, iPad, and Apple Watch models, infringe on the LTE patents. Optis Wireless and the other plaintiffs acquired many of the patents from Ericsson, Samsung, LG, and Panasonic — read the full complaint [PDF] for the exact patents.
The plaintiffs state that, not later than January 6, 2017, they sent Apple correspondence in an effort to license their essential patents to Apple on FRAND terms. The plaintiffs also allege meeting with Apple representatives on numerous occasions, but the parties did not reach a licensing agreement.
The plaintiffs are seeking "recovery of damages at least in the form of reasonable royalties" and have demanded a jury trial.
Last August, in the same court, a jury decided that Huawei willfully infringed many of the same LTE patents being asserted against Apple. The Chinese smartphone maker was ordered to pay $10.6 million in damages.
