Royalty Payments 6.1 During the TERM of this Agreement, as partial consideration for the LICENSE, LICENSEE shall pay to YALE an earned royalty of [***] percent ([***]%) of worldwide cumulative NET SALES of LICENSED PRODUCTS by LICENSEE or its SUBLICENSEES or AFFILIATES (“EARNED ROYALTY”).
6.1.1 The obligation to pay royalties under this Article 6.1 shall be imposed only on the original sale of any individual LICENSED PRODUCT to the end-user thereof, and the royalty shall be imposed only once on such sale regardless of whether such LICENSED PRODUCT is covered by more than one patent claim within the LICENSED PATENTS.
6.1.2 In the event that LICENSEE determines that it is necessary to obtain a license from a third party in order to avoid infringing a third party’s patent(s) by making, having made, using, offering for sale, selling, having sold, importing or exporting LICENSED PRODUCTS, LICENSEE may reduce its applicable royalty obligation to YALE by an amount which is the lesser of (i) [***], or (ii) [***].
6.1.3 The multiplier to be used to reduce the running royalties paid by LICENSEE to YALE on a COMBINATION PRODUCT, defined as a product containing a LICENSED PRODUCT and one or more additional products containing active ingredients sold together as a single product by LICENSEE, AFFILIATES or SUBLICENSEES, will be calculated by [***].
6.1.4 Notwithstanding the foregoing, in no event shall the operation of Articles 6.1.2 or 6.1.3 result in EARNED ROYALTIES payable to YALE being reduced to less than [***] percent ([***]%).
6.1.5 Should a compulsory license be granted by LICENSEE or an AFFILIATE to a third party under the applicable laws, rules, regulations, guidelines, or other directives of any governmental or supranational agency in the LICENSED TERRITORY under the LICENSED PATENTS, LICENSEE shall notify YALE, including any material information concerning such compulsory license, and the running royalty rates payable under Article 6.1 for sales of LICENSED PRODUCTS in such country will be adjusted to equal any lower royalty rate granted to such third party for such country with respect to the sales of LICENSED PRODUCTS therein.
6.2 In the event that (i) LICENSEE or any of its AFFILIATES or SUBLICENSEES brings a PATENT CHALLENGE anywhere in the world, or (ii) LICENSEE or any of its AFFILIATES or SUBLICENSEES assists another party in bringing a PATENT CHALLENGE anywhere in the world, and (iii) YALE does not choose to exercise its rights to terminate this Agreement pursuant to Article 13, then the following provisions shall apply.
(a) All payments due to YALE under this Agreement other than patent costs shall be [***] during the pendency of the PATENT CHALLENGE and shall remain payable to YALE when due.
(b) If the PATENT CHALLENGE is inconclusive or results in a determination that at least one challenged claim is both valid and infringed,
(i) all payments due to YALE under this Agreement other than patent costs shall be [***] for the remainder of the TERM of the Agreement.
(ii) LICENSEE shall promptly reimburse YALE for all legal fees and expenses incurred in YALE’s defense against the PATENT CHALLENGE.
(c) In the event that such a PATENT CHALLENGE is successful, LICENSEE will have no right to recoup any payments made prior to the final, non-appealable determination of a court of competent jurisdiction.
6.3 Neither LICENSEE nor any of its AFFILIATES or SUBLICENSEES shall bring a PATENT CHALLENGE without first providing YALE [***] written notice setting forth (a) precisely which claims and patents are being challenged or claimed not to be infringed, (b) a clear statement of the factual and legal basis for the challenge, and (c) an identification of all prior art and other matter believed to invalidate any claim of the LICENSED PATENT or which supports the claim that the LICENSED PATENT is not infringed.
6.4 LICENSEE shall pay all EARNED ROYALTIES accruing to YALE within [***] from the end of each calendar quarter (March 31, June 30, September 30 and December 31), beginning in the first calendar quarter in which NET SALES occur. Unless YALE requests otherwise, LICENSEE shall report all EARNED ROYALTIES and other payments accruing to YALE on a quarterly basis, but shall defer payments accruing to YALE that do not, in total, exceed [***] Dollars ($[***]) in any given quarter until the earlier of (1) the end of the calendar year, or (2) the quarter upon which the cumulative accrued royalties and other payments exceed [***] Dollars ($[***]).
6.5 All EARNED ROYALTIES and other payments due under this Agreement shall be paid to YALE in United States Dollars. In the event that conversion from foreign currency is required in calculating a payment under this Agreement, the exchange rate used shall be the Interbank rate quoted by Citibank at the time the payment is due. If overdue, the royalties and any other payments due under this Agreement shall bear interest until payment at a per annum rate [***] percent ([***]%) above the prime rate in effect at Citibank on the due date. The payment of such interest shall not foreclose YALE from exercising any other right it may have as a consequence of the failure of LICENSEE to make any payment when due.
