A federal appeals court has upheld a New Jersey judge's dismissal of a patent infringement suit against travel website Kayak.com.

The U.S. Court of Appeals for the Federal Circuit in an opinion dated Sept. 7 let stand a decision by the late U.S. District Judge Joseph Irenas that Kayak's quote-generating software did not infringe a patent held by plaintiff Source Search Technologies, or SST. The appeals court ruling also lets stand the finding that the case was “exceptional” and the award of $578,085 in legal fees to Kayak.

SST, based in Upper Saddle River, claimed in a 2011 complaint that its '328 patent, titled “computerized quotation system and method,” was infringed by Kayak. SST said Kayak was infringing its patent for “a method and system that allows a central computer to filter requests for quotes, and to interface to various vendor computers to obtain and forward such quotes to potential buyers of goods and services,” according to the amended complaint filed in 2013.
