Prosecution History Disclaimer after Top Brand v. Cozy Comfort

Episode 1 of Prosecuting Design Patents for Enforcement, a series on what design patent litigation teaches about prosecution.

This episode discusses how the Federal Circuit applied prosecution history disclaimer to a design patent in Top Brand v. Cozy Comfort, and what that means for how you draft and argue responses to office actions so the patent holds its scope when it is later enforced. It also covers the related doctrine of prosecution history estoppel.
