**SUPPLEMENTARY INFORMATION:**
Section 156 of Title 35, United States Code, generally provides that the term of a patent may be extended for a period of up to five years if the patent claims a product, or a method of making or using a product, that has been subject to certain defined regulatory review, and that the patent may be extended for interim periods of up to a year if the regulatory review is anticipated to extend beyond the expiration date of the patent.
On March 25, 2005, patent owner Roche Palo Alto LLC, timely filed an application under 35 U.S.C. 156(d)(5) for a third interim extension of the term of U.S. Patent No. 4,567,264. The patent claims the active ingredient ranolazine (Ranexa <sub>TM</sub> ). The application indicates, and the Food and Drug Administration (FDA) has confirmed, that a New Drug Application for the human drug product ranolazine has been filed and is currently undergoing regulatory review before the FDA for permission to market or use the product commercially.
Review of the application indicates that, except for permission to market or use the product commercially, the subject patent would be eligible for an extension of the patent term under 35 U.S.C. 156, and that the patent should be extended for an additional period of one year as required by 35 U.S.C. 156(d)(5)(C). Since it is apparent that the regulatory review period will continue beyond the extended expiration date of the patent (May 18, 2005), the term of the patent will be extended under 35 U.S.C. 156(d)(5) for an additional year.
An interim extension under 35 U.S.C. 156(d)(5) of the term of U.S. Patent No. 4,567,264 is granted for an additional period of one year from the extended expiration date of the patent, *i.e.* , until May 18, 2006.
