Patent Prosecution and Maintenance 14.1 REGENTS will diligently prosecute and maintain the United States and foreign patent applications and patents under REGENTS' PATENT RIGHTS, subject to LICENSEE’S reimbursement REGENTS’ out of pocket costs under Paragraph 14.3 below, and all patent applications and patents under REGENTS’ PATENT RIGHTS will be held in the name of REGENTS. REGENTS will have sole responsibility for retaining and instructing patent counsel, but continued use of such counsel at any point in the patent prosecution process subsequent to initial filing of a U.S. patent application covering the INVENTION shall be subject to the approval of LICENSEE. If LICENSEE rejects three of REGENTS’ choice of prosecution counsel, then REGENTS may select new prosecution counsel without LICENSEE’s consent. REGENTS shall promptly provide LICENSEE with copies of all relevant documentation so that LICENSEE may be currently informed and apprised of the continuing prosecution and LICENSEE agrees to keep this documentation confidential in accordance with Article 26. LICENSEE may comment upon such documentation, provided, however, that if LICENSEE has not commented upon such documentation in reasonable time for REGENTS to sufficiently consider LICENSEE’s comments prior to the deadline for filing a response with the relevant government patent office, REGENTS will be free to respond appropriately without consideration of LICENSEE's comments. LICENSEE and LICENSEE's patent counsel will have the right to consult with patent counsel chosen by REGENTS. 14.2 REGENTS will use reasonable efforts to prepare or amend any patent application to include claims reasonably requested by LICENSEE to protect the LICENSED PRODUCTS contemplated to be SOLD or to be practiced under this AGREEMENT. 14.3 Subject to Paragraphs 14.4 all past, present, and future costs for preparing, filing, prosecuting, and maintaining all United States and foreign patent applications, and patents under REGENTS’ PATENT RIGHTS will be borne by LICENSEE, so long as the licenses granted to LICENSEE herein are exclusive. Payments are due within thirty (30) days after receipt of invoice from REGENTS. If, however, REGENTS reduces the exclusive licenses granted herein to non-exclusive licenses pursuant to Paragraphs 7.3, 7.4, or 7.5 and REGENTS grants additional license(s), the costs of preparing, filing, prosecuting and maintaining such patent applications and patents will be divided equally among the licensed parties from the effective date of each subsequently granted license AGREEMENT. 14.4 LICENSEE's obligation to underwrite and to pay all domestic and foreign patent filing, prosecution, and maintenance costs will continue for so long as this AGREEMENT remains in effect, provided, however, that LICENSEE may terminate its obligations with respect to any given patent application or patent in any or all designated countries upon three (3) months’ written notice to REGENTS. REGENTS will use its best efforts to curtail patent costs when such a notice is received from LICENSEE. REGENTS may continue prosecution and/or maintenance of such applications or patents at its sole discretion and expense; provided, however, that LICENSEE will have no further right or licenses thereunder.
