Pioneer Magnetics Inc. v. Micro Linear Corp.

Case Number: CLB0014

Date: 02.12.2003

Citation: 65 U.S.P.Q.2d 1826 (Fed. Cir. 2003)

Narrowing amendment to independent claim at issue was not inadvertent, and was made for substantial reason related to patentability, namely, to avoid prior art; prosecuting attorney’s declaration that narrowing limitation was added inadvertently cannot be considered in determining reason for amendment, since it is not part of the prosecution history, and prosecution history does not show that reason for amendment was inadvertent.
