Other than the limited license you grant in the preceding paragraph of this Section, Evernote acknowledges and agrees that it obtains no right, title or interest from you (or your licensors) under these Terms of Service in or to any Content that you submit, post, store, transmit or display on, or through, the Service, including any intellectual property rights which subsist in that Content (whether those rights happen to be registered or not, and wherever in the world those rights may exist)."
