Neither Party shall, and each Party shall ensure that its Affiliates and their respective sublicensees do not, use or disclose any Confidential Information of the other Party or any nonpublic information regarding the prosecution or enforcement of any Licensed Patent Rights to which a Party or any of its Affiliates or sublicensees are or become privy as a consequence of the rights granted to such Party pursuant to this Agreement, in initiating, requesting, making, filing or maintaining, or in funding or otherwise assisting any other Person with respect to, any Challenge.

Notwithstanding the foregoing, if any Primary Patent is asserted against Legacy, any Affiliate thereof, or any Legacy Licensees or any subcontractors of any of the foregoing, under the direction of Legacy or any Affiliate thereof (in the case of any such assertion against any Third Party Legacy Licensees), or Primary, any Affiliate thereof, or any Third Party (in the case of Legacy, its Affiliates, and Legacy Licensees), then, as applicable, Legacy, its Affiliates, and Legacy Licensees are entitled to all and any defenses available to them with respect to such matter, including challenging the validity or enforceability of such patent, or undertaking any of the other actions referenced above (and such challenge or other action by Legacy, its Affiliates, or any Legacy Licensees in response to such an assertion shall not be considered a “Patent Challenge” for purposes of this [Section 7.4]).

Termination for Patent Challenge.
