IPCom GmbH & Co. v. HTC Corp.

IPCom’s 830 patent describes and claims a method and system for handing over a mobile phone call from one base station to another base station. After IPCom sued HTC for infringement, HTC successfully requested that the U.S. Patent and Trademark Office conduct inter partes reexamination of claims 1, 5–26, and 28–37. In the first round, the Examiner concluded that the claims were patentable, but the Patent Trial and Appeal Board issued a new ground of rejection for claims 1 and 5–30. In the second round, IPCom amended claims 1, 5–26, and 28–37, but the Board found that these amended claims were obvious under 35 U.S.C. 103 in view of various combinations of prior art. The Federal Circuit concluded, under the circumstances of this case, the Board properly had the authority to consider the patentability of claims 31–37. In its first decision, the Board did not address whether claims 31–37 should be regarded as obvious, but those claims were amended after the first round. The court agreed with IPCom that the Board failed to conduct a proper claim construction of the “arrangement for reactivating the link” claim limitation and vacated the obviousness rejections based on that limitation.
