Unwired Planet International, Ltd. is an intellectual property licensing company, often characterized as a Non-Practicing Entity (NPE) or Patent Assertion Entity (PAE). While it traces its origins to Libris Inc., founded in 1994 and later known as Openwave Systems Inc., the company transformed in November 2011. At that time, Openwave sold its product businesses and was rebranded Unwired Planet, dedicating itself exclusively to patent licensing and enforcement. This specific entity, Unwired Planet International Limited, is organized under the laws of Ireland, with a principal place of business in Dublin.
The company's operations are solely focused on monetizing its patent portfolio through licensing. This portfolio includes a substantial number of Standard Essential Patents (SEPs) related to major telecommunications standards such as 2G GSM, 3G UMTS, and 4G LTE. A significant portion of these patents, specifically 276 patents and applications across 42 countries, was acquired from Ericsson in 2013. The company's business model involves asserting these patents against implementers in the telecommunications industry.
Unwired Planet International, Ltd. operates as an NPE asserting an acquired patent portfolio, with its litigation posture entirely plaintiff-sided. The company's sole tracked U.S. patent litigation case, Optis Wireless Technology, LLC et al. v. Apple Inc., lists Unwired Planet International, Ltd. as a plaintiff in the U.S. District Court for the Eastern District of Texas, a venue known for its high volume of patent assertion cases.
Beyond the U.S., Unwired Planet has been a prominent litigant in major international patent disputes, particularly in the United Kingdom. Its landmark cases against companies like Huawei, Samsung, and Google in the UK focused on the licensing of Standard Essential Patents (SEPs) on Fair, Reasonable, and Non-Discriminatory (FRAND) terms, resulting in significant legal precedents regarding the jurisdiction of courts to set global FRAND royalty rates. The company's involvement in the Optis Wireless Technology case also suggests a connection or prior acquisition by PanOptis, as noted in previous litigation contexts.
