DECISION

Five Star Manufacturing, Inc. (“Five Star”) appeals from a jury verdict and final judgment of the District Court for the District of Kansas, dismissing Five Star’s claim for infringement against Ramp Lite Manufacturing, Inc. (“Ramp Lite”) and declaring U.S. Patent No. Des. 331,305 invalid for functionality. Ramp Lite cross-appeals, seeking a declaration that the ’305 patent is not infringed and is invalid for obviousness, improper inventorship, and an on-sale bar. Ramp Lite also seeks a declaration that Five Star is estopped from asserting the ’305 patent against Ramp Lite and requests a remand in order to determine whether the ’305 patent is unenforceable due to inequitable conduct. Because there is substantial evidence to support the jury’s verdict of invalidity for functionality of the patented design, we affirm. Ramp-Lite’s cross-appeal is dismissed as moot.
