Technical Expert’s Indefiniteness Opinions Excluded as Irrelevant for Relying on Claim’s Intended Result

The court granted plaintiff's motion to exclude the testimony of defendants' technical expert regarding defendants' enablement and written description theories as irrelevant. "Defendants conclude the claim limitation doesn’t satisfy the written-description or enablement requirements because the reduction can be achieved in more ways than just reducing the thickness of the insulator. But the proper focus is on structure rather than the intended result. [The claim at issue] is directed to a device, and the specification describes an embodiment of that device . . . . While the limitation recites the result of selecting that range, that result is not a structural limitation of the claim. Because his opinion is based on an incorrect interpretation of the limitation, the Court will grant the motion and exclude as irrelevant [the expert's] opinion that the specification does not provide guidance as to how the parasitic capacitance is reduced."
