monetary recovery that is for reasonable royalties or lost profits and *** of any related enhanced, increased or punitive damages. LICENSEE must notify UTMDACC in writing of any potential infringement in the LICENSED FIELD within thirty
(30) calendar days of knowledge thereof. If LICENSEE does not file suit against a substantial infringer in the LICENSED FIELD within nine (9) months of knowledge thereof, then BOARD or UTMDACC may, at its sole discretion, enforce any
patent licensed hereunder on behalf of itself and LICENSEE, with UTMDACC retaining all recoveries from such enforcement, and/or reduce the license granted hereunder to non-exclusive.

parties granting licenses to the PATENT RIGHTS and/or TECHNOLOGY RIGHTS in other fields of use outside of the LICENSED FIELD (Pre-Existing Agreements). These Pre-Existing Agreements contain language regarding the third parties
rights and obligations in the event of infringement of the PATENT RIGHTS. To the extent the provisions of this ARTICLE VII conflict with these Pre-Existing Agreements, LICENSEE understands and agrees that the Pre-Existing Agreements shall control.
