Title: Airespace's Statement about IPR claimed in draft-calhoun-seamoby-lwapp-03.txt Received: July 22, 2003 From: Pat R. Calhoun Airespace, Inc. has advised the IETF that it holds three currently pending U.S. patent applications (one entitled "Light-Weight Access Point Protocol" and two entitled "Method and System for Hierarchical Processing of Protocol Information in a Wireless LAN") that Airespace believes include at least one patent claim essential to implement the LWAPP protocol as specified in draft-calhoun-seamoby-lwapp-03.txt (the "Specification"). Airespace hereby covenants that it will not assert any patent claims contained in any of the above-identified pending patent applications (if and when issued as a Patent) against any party that makes, uses, sells, imports, or offers for sale, an implementation of the LWAPP protocol as specified in the Specification, assuming it is adopted. This covenant extends only to those patent claims contained in one of the above-identified patent applications that are necessary to implement the identified LWAPP protocol, and shall not extend to any other intellectual property rights of Airespace. The covenant applies only to assertion of those specified patent claims against a party based on that party's implementation of the LWAPP protocol, and shall not limit the rights of Airespace to assert any patent claims against infringing activities that are not necessary to implement the LWAPP protocol. The covenant shall not apply to (and Airspace shall be free to assert the above identified claims against) any party that asserts a patent it owns or controls against Airespace, either directly or indirectly, based on implementation or operation of a system utilizing the LWAPP protocol.
