2.3. Limitations on Grant Scope

The licenses granted in this Section 2 are the only rights granted to You under this License.

5.2. If You initiate litigation against any entity by asserting a patent infringement claim ( excluding declaratory judgment actions, counter-claims, and cross-claims ) alleging that a Contributor Version, distributed in accordance with the terms of this License, directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate.
