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 April 30, 2004, patent owner, L'Oreal S.A., timely filed an application under 35 U.S.C. 156(d)(5) for a second interim extension of the term of U.S. Patent No. 4,585,597. The patent claims the active ingredient Mexoryl^TM SX (ecamsule) in the human drug product ANTHÉLIOS^TM SP, a method of use of the ecamsule, and a method of manufacturing ecamsule. The application indicates, and the Food and Drug Administration has confirmed, that a New Drug Application for the human drug product ANTHÉLIOS^TM SP (ecamsule) has been filed and is currently undergoing regulatory review before the Food and Drug Administration for permission to market or use the product commercially. The patent was previously extended for a term of one year.

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. Since it is apparent that the regulatory review period will continue beyond the extended expiration date of the patent (June 16, 2004), the term of the patent is extended under 35 U.S.C. 156(d)(5) for an additional term of one year, i.e., until June 16, 2005.
