The Court provided three separate reasons that Sidense's technology does not infringe any of Kilopass' asserted patents. First, the Court found that Sidense does not have a "row wordline segment coupled to the second doped semiconductor region." The Court found that Kilopass had taken contradictory positions before the Court and the United States Patent Office and, as a result, had disavowed this claim scope. Second, the Court determined that Sidense's accused technology did not have the required "first doped semiconductor region," rejecting Kilopass' argument that a shallow trench isolation in Sidense's design was equivalent to the claimed "doped semiconductor region." Finally, the Court determined that Sidense's design did not have a first and second doped semiconductor region in a "spaced apart relationship" as required by the claims. While any one of these reasons would have been sufficient for Sidense to prevail, the Court's opinion finding three separate reasons that Sidense does not infringe bodes well for Sidense should Kilopass decide to appeal the Court's decision.
"We are extremely pleased with the judge's ruling, which validates our long-standing belief that the Kilopass patent claims against Sidense are without merit," said Xerxes Wania, Sidense President and Chief Executive Officer. "We've spent a considerable amount of time and money to prove that we're right in this litigation. We refused to be held hostage by this frivolous lawsuit, and now we've been vindicated."
