Claim Construction Knocks Out Prior Art

Posted in Claim Construction, Summary Judgment

Carrier Vibrating Equip., Inc. v. General Kinematics Corp., No. 10 C 5110, Slip Op. (N.D. Ill. Sept. 27, 2012) (Dow, J.).

Judge Dow granted plaintiff Carrier Vibrating Equipment’s (“Carrier”) motion for summary judgment of validity and denied defendant General Kinematics’s cross motion for summary judgment of invalidity in this patent case related to controlling retention time of a casting on a vibratory conveyor.  The Court initially construed the claim “modifying” to require automatic modification of the angle of vibratory force.  That construction was critical because the parties agreed that the alleged prior art system did not allow for automatic modification of the angle of vibratory force.  The Court, therefore, granted Carrier summary judgment of validity with respect to the asserted piece of prior art.
