This is an appeal from a decision of the Patent and Trademark Office (“PTO”) Board of Appeals (“board”) which affirmed the examiner’s rejections of claims 1-17
BACKGROUND
Invention
The invention relates to computer apparatus and process for preparing a complete set of printed architectural specifications, which describe the various materials and techniques used in constructing a building. Because to a considerable extent such specifications are repetitious or contain a combination of often-used phrases, appellants have made a list of standard phrases, stored the phrases in a digital computer’s memory (referred to as the data file), and associated a short, symbolic character with each phrase. To write a specification, a specifier selects the appropriate phrases and marks the corresponding symbolic characters on an order form in the desired sequence. The series of symbolic characters is supplied to the computer, already programmed, which edits the characters for error, selects the
Claim 7 is illustrative of the apparatus claims:
7. A system for preparing a printed architectural specification comprising: Specification Data File means including a quantity of predetermined information stored in a data processor memory and divided into individual phrases with predetermined indentation for print-out, said phrases being recallable by means of a Specification Index File means; and a programmed data processor adapted to receive input coded characters representative of a predetermined sequence and outlining of said phrases in said Specification Data File means for preparing an edited input data file free of fatal errors; said data processor being further programmed to print out a set of specifications according to the input code of the specifier from the Specification Data File and said edited input file.
Claim 15 is illustrative of the process claims:
15. A process for preparing an architectural specification comprising: storing recorded signals representative of instruction data on an instruction data file; storing recorded signals representative of a plurality of phrases with associated code on a specification data file, whereby a specifier by writing code may determine the sequence and relation of said phrases; programming a data processor to receive input code representative of a predetermined sequence of said phrases and to check said input code to determine whether it contains any errors which would prevent further processing of said input code and, if not, to prepare an edited input file of said code; programming said processor to process the code on said edited input file and to prepare a printed specification from said specification data file according to the code sequenced by a specifier and to prepare a set of signals on an instruction input file, said last-named signals being correlated with said phrases through said input code; and programming said data processor to operate on said instruction input file to prepare a set of instructions from said instruction data file; said instructions being associated with corresponding data on said printed specification.
Proceedings Below
The examiner rejected the claims under 35 U.S.C. § 101
There is nothing in the specification to suggest that there is any other substantial practical application [of the invention] except in connection with a digital computer. The Supreme Court of the United States in Gottschalk v. Benson et al.,409 US 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. . . .
The examiner also rejected the claims under 35 U.S.C. § 112, first paragraph,
Board Decisions
The board affirmed the examiner’s rejection under 35 U.S.C. § 101, quoting at length the reasoning of the examiner, including the portion quoted earlier in this opinion.
The board also affirmed the examiner’s rejection under 35 U.S.C. § 112, first paragraph, and stated that the proper test concerning sufficiency of a flow chart is:
Will the programmer find within the four corners of the disclosure at hand enough to allow him to proceed or will it be necessary for him to seek additional instructions from the person who prepared the flow chart?
The board found the following inadequacies in appellants’ specification: (1) The proper criteria for “fatal errors” in Figure 7, block 72, are not explained; (2) The criteria for “validity” in Figure 9, blocks 98 and 99, are not given; and (3) The criteria for “specification error” in Figure 14, block 246, are not given. It said that the general statements in the Hotton affidavit failed to shed any light on these inadequacies.
On reconsideration, the board reviewed its decision in light of Parker v. Flook,
Remand From CCPA
This case was originally scheduled to be heard on April 4, 1979, but was removed from the calendar and remanded to the board. The court’s per curiam opinion included the following statement (In re Phillips,
the board’s opinion . . . lacks the specifies of a detailed factual analysis of the subject matter as a whole of appellants’ invention (see this court’s opinion in In re Johnson,589 F.2d 1070 ,200 USPQ 199 (CCPA 1978), and In re Gelno-vatch,595 F.2d 32 , [201 USPQ 136 ] (CCPA 1979)), which is required to show wherein this court’s opinions in In re Chatfield, [545 F.2d 152 ,191 USPQ 730 (CCPA 1976)], In re Noll, [545 F.2d 141 ,*882 191 USPQ 721 (CCPA 1976)], 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 unpat-entable.
Accordingly, the board was directed to prepare “a supplemental opinion that will provide the specifics of a detailed factual analysis ... to enable the court to properly consider the appeal . . . .”
Board’s Supplemental Opinion
In a long opinion which makes an attempt to provide a “detailed factual analysis,” the board adhered to its original decision. It said that the antecedent features that provide input data to the data processing means are comparable to the “antecedent steps of establishing values in the equation” referred to in In re Christensen,
In its analysis, the board applied the two-step Freeman test, namely: (1) determine whether the claim directly or indirectly recites an “algorithm” in the Benson (and Flook) sense of the term (a procedure for solving a given type of mathematical problem); (2) if such an algorithm is recited, then determine whether the claim in its entirety wholly preempts that algorithm. In re Freeman,
OPINION
Section 101 Issue
The board’s position, in essence, is that because a digital computer “operates mathematically, employing numerical quantities according to at least one radix,” all claims directed to computer-related inventions are directed to an “algorithm” within the meaning of that term in Benson and Flook, supra. Such a position was effectively repudiated by this court in the recent cases of In re Bradley,
Our analysis of the claims on appeal reveals no recitation, directly or indirectly, of an algorithm in the Benson and Flook sense. The board clearly erred in finding that the first step of the Freeman test is satisfied. See In re Toma, supra.
Accordingly, we hold that appellants’ claims meet the requirements of 35 U.S.C. § 101.
Section 112, First Paragraph, Issue
Appellants’ invention includes an error checking feature. They have defined certain errors as “fatal errors” to be those which are so crucial that the process should halt for immediate correction. Other errors, called “specification errors,” will permit the program to run, but are printed out after the program has run so that they may be corrected. Appellants’ specification implies that “fatal” and “specification” errors other than those illustrated may be identified. However, the board and solicitor have interpreted this to mean that other errors must be defined in order to write a program, and have concluded that appellants, therefore, have not satisfied the enablement requirement of section 112. This position is not well taken. Appellants have listed the minimum number of errors that must be corrected before the process can function (“fatal errors”) and the errors that they desire to have the option of correcting (“specification errors”). Additional errors may be identified, but they are not necessary to the invention. Accordingly, we conclude that the appellants have sufficiently described the criteria for “fatal errors” and “specification errors.”
Another feature of appellants’ invention is a validity check on the symbolic characters supplied to the computer. Appellants, by merely stating that a validity check is to be made, have impliedly provided the necessary criteria. They have established a list of possible symbolic characters. A validity check of a symbolic character supplied to the computer is made by checking to see whether it matches a character on the list. If a match is made, the character is valid; otherwise, it is invalid. No further criteria are required. Therefore, we hold that the enablement requirement of 35 U.S.C. § 112, first paragraph, is satisfied.
In view of all the foregoing, the board’s decision affirming the rejections under 35 U.S.C. § 101 and 35 U.S.C. § 112, first paragraph, are reversed.
REVERSED.

. 35 U.S.C. § 101 reads as follows:
§ 101. Inventions patentable
Whoever Invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent therefor, subject to the conditions and requirements of this title.
. 35 U.S.C. § 112, first paragraph, reads as follows:
The specification shall contain a written description of the invention, and of the manner and process of making and using it, in such full, clear, concise, and exact terms as to enable any person skilled in the art to which it pertains, or with which it is most nearly connected, to make and use the same, and shall set forth the best mode contemplated by the inventor of carrying out his invention.
. The radix is “the quantity used to define a system of number representation by means of positional notation. It is the radix that is raised to the successive powers, the result then being multiplied by the given digits of the specified number. The radix number also is equal to the number of symbols, that is, character designs or different digits, required for the particular system of number representation. For example, in a radix 10 number system, there are 10 characters; namely, 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9.” Weik, Standard Dictionary of Computers and Information Processing (rev. 2d ed. 1977).
