WiLAN Subsidiary Polaris Signs License Agreement with NVIDIA

Parties Settle All Pending Litigations

OTTAWA, April 23, 2019 /PRNewswire/ - Wi-LAN Inc. ("WiLAN"), a Quarterhill Inc. ("Quarterhill") company (TSX: QTRH) (NASDAQ: QTRH), today announced that WiLAN's wholly-owned subsidiary, Polaris Innovations Limited ("Polaris"), has granted a term license for certain patents owned by Polaris to NVIDIA Corporation ("NVIDIA") as well as options for NVIDIA to renew through the life of the patents.  The licensed patents relate to memory interface technology and are part of the portfolio that Polaris acquired from Infineon Technologies in June 2015. The license fees payable to Polaris are confidential.

The license also settles all litigations pending between the parties in the US Federal Court for the Northern District of California, the District Court of Dusseldorf, Germany and the Inter Partes Review proceedings at the Patent Trial and Appeal Board of the United States Patent Office, some of the written decisions of which are under appeal at the US Court of Appeals for the Federal Circuit.  On March 28, 2019, the District Court of Dusseldorf found that one of the German patents asserted by Polaris against NVIDIA was infringed and would be provisionally enforceable inter alia by an injunction in favor of Polaris, upon Polaris posting a security bond and pending further proceedings in Munich. Subject to the terms of the license agreement however, the injunction granted by the Dusseldorf Court shall not be enforced by Polaris, and NVIDIA is not pursuing further proceedings to overturn the District Court decision.

"We are very pleased to have reached a comprehensive resolution with NVIDIA with respect to the Polaris memory interface patents," said Michael Vladescu, President and CEO of WiLAN.  "We believe this license further demonstrates the strength and breadth of the Polaris Portfolio which has now been licensed to numerous companies in various industry sectors including consumer electronics, semiconductor foundry, multimedia processors, DRAM and now graphics processors."
