¶1James J. Hill, Emrich, Root, O’Keeffe & Lee, Chicago, 111., for appellant.
¶2Joseph F. Nakamura, Sol., Thomas E. Lynch, Associate Sol., U. S. Patent and Trademark Office, Washington, D. C., for Patent Office.
¶3Before MARKEY, Chief Judge, and RICH, BALDWIN, LANE * and MILLER, Associate Judges.
¶6In this appeal, scheduled for hearing on April 4, 1979, the court, having considered the original opinion and decision of the Patent and Trademark Office Board of Appeals (“board”) and its subsequent opinion and decision upon request for reconsideration and modification, concludes as follows:
¶7The board quotes approvingly from the examiner’s answer, which states that the claims involve a program for use with a digital computer; that the program has no substantial practical application except in connection with such a computer; that the Supreme Court in Gottschalk v. Benson, 409 U.S. 63, 93 S.Ct. 253, 34 L.Ed.2d 273, 175 USPQ 673 (1972), “indicated that a program that has no substantial practical application except in connection with a digital computer is not patentable under 35 USC 101”; and that the Court, by quoting from the Report of the President’s Commission on the Patent System in which policy matters *1022were raised against the patenting of computer programs, “declined to decide such policy matters and refused to extend the patent statutes to embrace computer programming, absent a considered action by the Congress.” On reconsideration, the board says simply that appellants’ process is an “algorithm” (“a procedure for solving a given type of mathematical problem”) within the meaning given that term in Benson and Parker v. Flook, 437 U.S. 584, 98 S.Ct. 2522, 57 L.Ed.2d 451, 198 USPQ 193 (1978), apparently because use of a digital computer is contemplated.
¶8The board recognizes that the claims involved in Benson were method claims, but says that it regards the strictures of Benson as applicable to apparatus claims, for to do otherwise would be to allow a prospective patentee to achieve indirectly what he may not achieve directly. It says it finds nothing in In re Chatfield, 545 F.2d 152, 191 USPQ 730 (CCPA 1976), or In re Noll, 545 F.2d 141, 191 USPQ 721 (CCPA 1976), that would remove the instant application from the principles enunciated in Benson.
¶9Although the board says that each new appeal must be decided on its own facts “in view of interpretations of the patent law as handed down by the Supreme Court” (citing In re Christensen, 478 F.2d 1392, 178 USPQ 35 (CCPA 1973)), the board’s opinion, nevertheless, lacks the specifics of a detailed factual analysis of the subject matter as a whole of appellants’ invention (see this court’s opinions in In re Johnson, 589 F.2d 1070, 200 USPQ 199 (CCPA 1978), and In re Gelnovatch, 595 F.2d 32 (CCPA 1979)), which is required to show wherein this court’s opinions in In re Chatfield, supra, In re Noll, supra, In re Deutsch, 553 F.2d 689, 193 USPQ 645 (CCPA 1977), In re Toma, 575 F.2d 872, 197 USPQ 852 (CCPA 1978), and In re Freeman, 573 F.2d 1237, 197 USPQ 464 (CCPA 1978), do not apply to the instant claims and, particularly, wherein the differences between the instant claims and those involved in Benson are insufficient to bring those claims within the Supreme Court’s disclaimer in Benson (repeated in Dann v. Johnston, 425 U.S. 219, 96 S.Ct. 1393, 47 L.Ed.2d 692, 189 USPQ 257 (1976)) that it was not holding that all computer program inventions are unpatentable.
¶10Accordingly, it is ordered that the case be removed from the calendar and be remanded to the board for preparation of a supplemental opinion that will provide the specifies of a detailed factual analysis, as indicated above, to enable the court to properly consider the appeal; on receipt of the supplemental opinion, this appeal will be restored to the docket.
