Appeal No. 95-4878 Application No. 08/225,087 371. When a U.S. national application filed under § 111(a) becomes a U.S. patent, its effective date as a prior art reference against a pending application is its effective filing date.

See 35 U.S.C. §§ 120, 365(c), and MPEP, §§ 1896 and 2136.03 (II)(7th ed., July 1998). See also Hoover, Journal of the Patent and Trademark Office Society, Vol. 80, No. 4, pp. 289-295, April 1998. Therefore the effective date of the Bluml reference is May 19, 1988, the filing date of PCT/DE88/00304, and Bluml is available as a prior art reference under § 102(e) since it is “by another” and “filed before the invention thereof by the 6Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 NextLast modified: November 3, 2007
