(6) A COMPLETE IDENTIFICATION OF THE PATENT FOR WHICH AN EXTENSION IS BEING SOUGHT BY THE NAME OF THE INVENTOR, THE PATENT NUMBER, THE DATE OF ISSUE, AND THE DATE OF EXPIRATION: Patent No.: 7,605,238 - 7 - Docket No.: 029420.0155-US02 UNITED STATES PATENT NO.: 7,605,238 INVENTORS: ALAN 1. KORMAN EDWARD L. HALK NILS LONBERG Y ASHW ANT M. DEO TIBOR P. KELER DA TE OF ISSUE: OCTOBER 20, 2009 EXPIRATION DATE: AUGUST 24,2020' The expiration date of U.S. Patent No. 7,605,238 ("the '238 patent") is August 24, 2020, based on the following information. The patent application that issued as the '238 patent, U.S. Patent Application No. 09/948,939 ("the '939 application"), was filed on September 7, 2001 as a continuation-in-part or U.S. Patent Application No. 09/644,668 fied on August 24,2000, now U.S. Patent No. 6,984,720 (the '''720 patent"), and claims the benefit of U.S. Provisional Patent Application No. 60/150,452, fied on August 24, 1999, now expired. The expiration of the '238 patent pursuant to 35 U.S.C. § 154 is August 24,2020. However, the '238 patent is subject to a terminal disclaimer fied to the '720 patent. The expiration date of the '720 patent is August 2, 2022, which includes a patent term adjustment pursuant to 35 U.S.C. § 154 of 708 days. Therefore, the expiration date of the '238 patent need not be shortened in view of the patent term of the '720 patent. i The expiration date identified for U.S. Patent No. 7,605,238 in this Request is based on the assumption that the '238 patent is not entitled to rely on the patent term adjustment that was granted to U.S. Patent No. 6,984,720, despite the language of the terminal disclaimer. However, if the PTO or the courts take the position that, in the circumstance such as the '238 patent, the '238 patent is entitled to rely on the patent term adjustment granted to the '238 patent, then Applicant reserves the right to amend this Request to seek a patent term extension application based on an expiration date of August 2, 2022 for the '238 patent.
