Hewlett Packard and Teradata sought inter partes review of certain claims of U.S. Patent No. 6,597,812, relating to systems and methods for providing lossless data compression and decompression that exploit various characteristics of run-length encoding, parametric dictionary encoding, and bit packing. The Board instituted review and, in its final written decision, found that all of the challenged claims would have been obvious over the prior art. Realtime Data, owner of the ’812 patent, appealed arguing: (1) that the Board erred in its determination that a person of ordinary skill in the art would have been motivated to combine the teachings of the prior art; and (2) that the Board erred by failing to construe the “maintaining a dictionary” limitation and in finding that the prior art disclosed the “maintaining a dictionary” limitation. The CAFC finds that the Board did not err in concluding that the claims would have been obvious in view of a single reference and that the prior art disclosed the “maintaining a dictionary” limitation, and therefore affirms.
