Plaintiff-Appellant Howmedica Osteonics Corporation (“Howmedica”) appeals from a final judgment of noninfringement in this patent infringement action against defendant-appellee Wright Medical Technology, Inc. (“Wright”). Under the district court’s claim construction of the term “femoral component including at least one condylar element,” the parties stipulated that the accused product did not infringe the asserted patent claims. Because we conclude that the construction of this claim term was incorrect, we cannot sustain the stipulated judgment. Furthermore, because we agree with the district court that Howmedica did not release its infringement claim as part of an earlier settlement agreement, Wright’s asserted alternative ground for affirmance does not support the judgment. Accordingly, we vacate the judgment of noninfringement, and remand to the district court for further proceedings consistent with this opinion.
