Federal Circuit: Disparagement of Prior Art in the Specification Can Limit Claim Language

UltimatePointer argued that the district court improperly construed “handheld device” to require direct pointing, because there was no disavowal or lexicography in the specification to exclude indirect pointing. Nintendo argued that the specification extols direct pointing and repeatedly criticizes indirect pointing. The Court agreed, holding that repeated characterization of the invention as a “direct pointing system,” repeated descriptions of the advantages of direct pointing, and repeated disparagement of indirect pointing all indicate that the term “handheld device” should be limited to direct pointing devices.
