The Intellectual Property team at Gowling WLG has secured another Court of Appeal win in 2023 for InterDigital, one of the world's largest mobile and video technology research and development companies, in its litigation against Lenovo. The Court of Appeal in London overturned the High Court's ruling on invalidity of a patent relating to 3G, finding that InterDigital's patent is valid and upheld the High Court's ruling that the patent is essential and infringed.
The judgment follows the UK Court of Appeal's decision in January to uphold the lower court's verdict that Lenovo is infringing a valid and essential InterDigital cellular 4G patent. A decision is still pending in a separate trial to determine fair, reasonable and non-discriminatory terms for a license to InterDigital's portfolio.
Alexandra Brodie and Jamie Rowlands, patent litigation partners, principal associate Andrew Maggs and associate Olivia Nimmo, represented InterDigital in this case.
Commenting on the judgment, Alexandra Brodie said:
"We are delighted to have helped InterDigital secure another win in its longstanding dispute with Lenovo. This particular case saw the team overturn the lower court's judgment of invalidity resulting in the patent being held essential, valid and infringed. This string of wins on SEP disputes is also a fantastic reflection of the strength, expertise and commitment of our team."
Jamie Rowlands added:
"I'm extremely proud of everyone in the team working on this case as we have now won every decision so far in this dispute with Lenovo which is an exceptional result in SEP/FRAND litigation. This latest victory further cements the quality of InterDigital's patent portfolio and gives us confidence as we await the outcome of the "FRAND" trial with the UK Patent Court."
