Patent Licensing Agreement. From January 2009 to February 2015, under our license agreement with Alere, we licensed co-exclusively certain worldwide patent rights related to lateral flow immunoassay technology in the field of animal health diagnostics in the professional marketplace. The license agreement enabled us to develop and market products under rights from Alere in the animal health and laboratory animal research markets. In exchange for the license rights, we (i) paid an up-front license fee of $5.0 million to Alere in January 2009, (ii) agreed to pay royalties during the term of the agreement, based solely on sales of products in a jurisdiction country covered by valid and unexpired claims in that jurisdiction under the licensed Alere patent rights, and (iii) agreed to pay a yearly minimum license fee of between $0.5 million to $1.0 million per year, which fee was creditable against any royalties due during such calendar year. The royalties, if any, were payable through the date of the expiration of the last valid patent licensed under the agreement that includes at least one claim in a jurisdiction covering products we sell in that jurisdiction. The yearly minimum fees were payable for so long as we desire to maintain exclusivity under the agreement. Effective February 2015, we terminated our license agreement with Alere. In accordance with the terms of the license agreement, we had no outstanding liabilities related to this license agreement as of September 30, 2015.
