Publicly traded InterDigital, Inc. has been hit with an international salvo of complaints over the NPE’s alleged breach of its fair, reasonable, and non-discriminatory (FRAND) licensing obligations as to certain standard essential patents (SEPs) covering cellular technologies. In California, Swiss semiconductor firm u-blox has sued InterDigital for allegedly insisting on unfair and discriminatory licensing terms for certain 2G, 3G, and 4G patents while using abusive tactics to force it to take a license, including inappropriate communications with its customers and downstream manufacturers. The plaintiff has asked the court to determine a FRAND licensing rate, enjoin InterDigital from making further contact with its clients, and to issue a declaration of noninfringement for certain wireless communications products, including cellular modules implementing the LTE standard. Meanwhile, InterDigital disclosed on January 7 that it was just sued in China by Huawei, which has alleged that the NPE has violated its FRAND obligations as to certain patents related to 3G, 4G, and 5G standards. Huawei has purportedly asked the court to determine the proper licensing rate for certain wireless products following the expiration of a license at the end of 2018.
