3.11 Royalty Payments and Reports . Royalties due under this Article 3 shall be payable on a country-by-country and Sublicensed Product-by-Sublicensed Product basis until the expiration of the last-to-expire issued Valid Claim covering such Sublicensed Product in such country, or if no such patent has previously issued in a country, until the fifth anniversary of the first commercial sale of Sublicensed Product in any country. For so long as royalties are payable under this Agreement, CDx shall provide a royalty report in writing to NDT on or before April 30 ^th , July 31 ^st , October 31 ^st , and January 31 ^st of each year.

(c) CDx shall have no right to recoup any royalties paid before such action or proceeding or during the period in which such action or proceeding is pending (including on appeal);
