Alston & Bird represented Amperex Technology Limited in multiple appeals by Maxell at the Federal Circuit. In a series of related wins for Amperex, the court affirmed four Patent Trial and Appeal Board rulings invalidating the claims of four Maxell patents. The patents—U.S. Patent Nos. 8,691,446; 9,077,035; 9,166,251; and 9,350,019—relate to rechargeable lithium-ion batteries and were asserted by Maxell against Amperex in a case pending in the Western District of Texas.
Representing Amperex was an Alston & Bird team led by partners Kirk Bradley, Brady Cox, and Chris Douglas and senior associate Nic Marais (Intellectual Property Litigation).
