UNITED STATES COURT OF APPEALS FOR THE FEDERAL CIRCUIT
Decided: November 20, 1987.
AQUA-AEROBIC SYSTEMS, INC., PLAINTIFF-APPELLEE,
RICHARDS OF ROCKFORD, INC., DEFENDANT-APPELLANT
Richards of Rockford, Inc., appeals from a final judgment of the United States District Court for the Northern District of Illinois, 1 USPQ2d 1945 (1986), holding Richards liable for willful infringement of claims 1-6 and 8 of U.S. Patent No. 3,606,273 (the '273 patent) issued to John Johnson and owned by Aqua-Aerobic Systems, Inc. On appeal, Richards challenges the court's holding of (1) validity of, inter alia, claims 1 and 2 and enforceability of Aqua's patent, which we affirm, and (2) infringement of claims 3-6 and 8, which we vacate. Thus, we affirm-in-part and vacate-in-part.*fn*
Affirm-in-part and Vacate-in-part.
* Richards' motion for leave to file a Supplemental Appendix in this case has been granted, and the contents of that Appendix have been considered.
