The prosecution history must be reviewed when interpreting a claim to “exclude any interpretation” that was “disclaimed or disavowed during prosecution.” Computer Docking Station Corp. v. Dell, Inc., 519 F.3d 1366, 1374-75 (Fed. Cir. 2008); ZMI Corp. v. Cardiac Resuscitator Corp., 844 F.2d 1576, 1580 (Fed. Cir. 1988). “A patentee may limit the meaning of a claim term by making a clear and unmistakable disavowal of scope during prosecution.” Computer Docking, 519 F.3d at 1374.If the applicant unequivocally disavows claim scope, the doctrine of prosecution disclaimer applies even if the disclaimer results in a negative claim limitation. See N. Am. Container, Inc. v. Plastipak Packaging, Inc., 415 F.3d 1335 (Fed. Cir. 2005) (affirming district court’s construction of claim term “generally convex” to require “a majority of convex points along the inner wall and no concave points,” as the applicant’s statements in the prosecution history disclaimed coverage of an inner wall with any concavity). Prosecution disclaimer may also arise from an applicant’s statements in a parent patent application if the parent application relates to the same subject matter as the claim language at issue. Ormco Corp. v. Align Tech., Inc., 498 F.3d 1307, 1314 (Fed. Cir. 2007).
