No Challenge Clause for Patent License
(Validity and Infringement) (Pro-Licensor)

Summary

This No Challenge Clause for a patent licensing agreement, which is drafted pro-licensor, settles a patent infringement suit. The licensee covenants that it will not challenge the validity or enforceability of the licensed patent in any forum, nor will it assert that the licensed activities infringe the licensed patent. A breach of the no challenge clause is deemed a material breach that entitles the licensor to terminate the license.
