"The U.S. Court of Appeals for the Federal Circuit (CAFC) on Tuesday affirmed a district court decision finding that Technology in Ariscale, LLC's patent for a transmission signal decoding method was patent ineligible under 35 U.S.C. § 101. The opinion was authored by Judge Cunningham. Ariscale first argued to the CAFC that the United States District Court for the Central District of California's characterization of claim 1 of its U.S. Patent No. 8,139,652 as being "directed to receiving, manipulating, and decoding data" constituted error."
"But the CAFC said this description "is not meaningfully different from that of the district court and does not suggest that the district court overgeneralized the claim." Ariscale's limitation of the claim to DFP information was not supported by the claim language, said the CAFC, and even if Ariscale was correct, "this would 'not change its character as information' or otherwise make it less abstract," the opinion added."
The CAFC affirmed a district court ruling that Ariscale's patent for a transmission signal decoding method is ineligible under 35 U.S.C. § 101. The court characterized the claims as directed to receiving, manipulating, and decoding data, not a specific technical improvement. Ariscale contended the claims were limited to combining and decoding repeatedly transmitted downlink frame prefix (DFP) information, but the court found that characterization unsupported by the claim language and not meaningfully different. The court concluded the claim language failed to disclose specific means, invoked generic processes, and held the combining step could not supply an inventive concept.
