Optical Tech IP, LLC’s campaign continues with a new suit filed against Huawei. The campaign, began in early November of this year, asserts a single patent (7,747,172) and targets networking companies. The patent-in-suit relates to improving bandwidth efficacy using electrical signal processing, and it was previously owned by Eye Diagram IP, LLC. Optical Tech acquired the asserted patent in May 2014. Similar to the previous suits in the campaign, the complaint in this suit accuses Huawei’s optical networking components of infringing the patent-in-suit.
