United States Federal Circuit

Summary judgment that plaintiffs did not infringe two of defendant's patents on improvements to electronic animal collars is: 1) affirmed in part as to the judgment of non-infringement for GS-011, FieldPro, and SD-1825 collars, where the district court correctly construed the claim terms "electrode base" and "inside surface," and correctly applied its constructions to these accused collars, 2) affirmed in part, where the district court did not abuse its discretion in concluding that equitable estoppel applied to defendant's '014 patent infringement allegations on the UltraSmart collar against both plaintiff Innotek and its successor-in-interest, plaintiff Radio Systems; but 3) reversed in part and remanded, as to the '082 patent, where the district court abused its discretion by granting summary judgment of non-infringement for the UltraSmart collar on the basis of equitable estoppel.
