CHICAGO, June 25 /PRNewswire/ -- The U.S. Court of Appeals for the Federal Circuit has issued a ruling affirming summary judgment in favor of defendant Alpine Electronics, Inc., and Alpine Electronics of America, Inc., in a long-running patent dispute with Encyclopaedia Britannica (EB) over a chain of patents dating to 1989.
The Alpine companies are industry leaders in multimedia products that include high-performance mobile and vehicle navigation systems. In Encyclopaedia Britannica, Inc. v. Alpine Elecs. of Am., Inc., plaintiff EB, a provider of learning and knowledge products, sought to reverse a district court's 2008 ruling that the company's asserted U.S. Patent Nos. 7,051,018 (the '018 patent) and 7,082,437 ('437) were invalid.
"Summary judgment in this case hinged entirely on the issue of statutory interpretation," noted Christopher A. Harkins, a Brinks attorney representing Alpine. "The Federal Circuit Court of Appeals concluded that U.S. Code section 120 requires each application in the chain of priority to refer to the prior applications, and that summary judgment had been properly granted."
"We are pleased we could document the broken chain of patent applications and accomplish this result in a cost-effective manner for Alpine," said Gary Ropski, president of Brinks. "This may well be the final chapter in Encyclopaedia Britannica's assertion of these patents."
The patents at issue were filed on June 13, 2005, and, through a chain of patents and patent applications, both claim priority back to U.S. Patent No. 5,241,671 ('671) of October 26, 1989. The decision in the current appeal hinged on whether these patents were entitled to the earlier priority date. In the case of EB, the company's later-filed '018 and '437 patents contained a reference to the earlier '671 patent, but an intermediate application in the chain of priority, No. 8/113,955, filed on Aug. 31, 1993, did not contain such a reference.
