the parties shall be under no obligation to enforce any of their Intellectual Property Rights against any actual or threatened Third Party infringements. 15 8.2 Biocept Technology. Without limiting the generality of the foregoing, Biocept owns, and Life Technologies acknowledges Biocept's ownership of, (i) the Assay and the Selector technology, and (ii) all Intellectual Property Rights in the Assay and the Selector technology, and Life Technologies agrees that it shall not do or suffer to be done any act or thing or undertake any action anywhere that in any manner might infringe, or impair the validity, scope, or title of Biocept in the Assay, the Selector technology or Intellectual Property Rights owned by Biocept. Nothing herein shall limit Life Technologies' ability to prosecute fully any and all Intellectual Property Rights owned by Life Technologies with any patent office or related government agency or to respond fully to any government agency inquiry with respect to its Intellectual Property Rights, products, and services. 8.3 New Technology. In the course of the activities conducted by the parties, Biocept and/or Life Technologies may conceive of inventions or discoveries or create works that constitute intellectual property and may be patentable or registerable as a copyright or other intellectual property right (all of the foregoing, including such intellectual property rights therein, collectively, "Developments"). Inventorship of all inventions and discoveries, whether or not patentable, will be determined in accordance with United States patent laws. Authorship of all copyrightable works will be determined in accordance with United States copyright laws. Subject to Section 8.2, as between the parties, Developments will be owned consistent with such determination of inventorship or authorship. To the extent any Development owned by Life Technologies relates directly to the practice of, or constitutes an improvement to, the Assay, Life Technologies hereby grants to Biocept, during the Term of this Agreement, and, except in the case of termination of this Agreement by Life Technologies for Biocept's uncured material breach, after expiration or termination of this Agreement, a non-exclusive, worldwide, royalty-free, fully-paid license, including the right to sublicense, under Life Technologies' Intellectual Property Rights in such Developments, solely to develop, make, have made, use, sell, have sold, offer for sale, import, perform and provide the Assay. To the extent any Development owned by Biocept relates directly to the practice of, or constitutes an improvement to, the Assay, Biocept hereby grants to Life Technologies, during the Term of this Agreement, a non-exclusive license under Biocept's Intellectual Property Rights in such Development, solely to promote the Assay in the Territory and to perform the Professional Component of the Assay sold by the parties in the Territory, in accordance with the terms of this Agreement. 8.4 Technology Licenses. To the extent that any Third Party Intellectual Property Rights related to the capture and detection of CTCs must be licensed to perform the Assay, such royalty shall be paid by Biocept. To the extent that either party owns Intellectual Property Rights to specific biomarkers, targets, kits, dyes or technology utilized in the Assay other than for the capture and detection of CTCs, it will, to the extent it is able, grant during the Term of the Agreement, a non-exclusive license to the other party to practice these Intellectual Property Rights for the Assay. To the extent that either party has licensed or will license Intellectual Property Rights from Third Parties related to specific biomarkers, targets, kits, dyes or technology utilized in the Assay other than for the capture and detection of CTCs, it will, to the extent it is able, grant, during the Term of the Agreement, a non-exclusive license to the other party, or ensure that the 16 other party is covered under its license, to practice these Intellectual Property Rights for the Assay. In the event of the foregoing, then, subject to Section 8.5, the parties agree to negotiate in good faith an allocation of expenses for such Third Party licenses directly associated with the Assay. 8.5 Infringement. If any Third Party claims or brings an action alleging that performance of the Assay or Test by Biocept or Life Technologies or their Affiliates under this Agreement infringe (directly or indirectly) any of such Third Party's patent rights, Biocept shall use commercially reasonable efforts to address such claims. If Biocept determines to seek a license or otherwise obtain the right to use such Third Party intellectual property rights on behalf of Biocept and Life Technologies, then (i) if the Third Party intellectual property rights relate to the capture and
