Nor are they attempting to use the draftsman’s skills to “word” a claim to appear as if it is drawn to something else when it in fact covers nothing but a computer program. Three examples are claims 1, 2, and 11, which diamon The computer then used the Arrhenius equation to calculate when sufficient energy had been absorbed so that the molding machine should open the press.

The brief diamojd of the operation of the digital computer on page 7, line is inadequate to comply with the requirements of the statute.

Diamond v. Diehr – RESPONDENTS’ BRIEF ON THE MERITS – IP Mall

Does a patent process claim drawn to subject matter which is otherwise statutory under 35 U. Apparently Gould et al.

Respondents have endeavored to survey cases involving computer-related claims and technology which have come before the CCPA and have come up with the following results as of July 1, 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.

During the conversion process, variables such as temperature, pressure, and flow rates were constantly monitored and fed into the computer; in this case, temperature in the mold is the variable that is monitored and fed into the computer.

A computer program will never mold rubber. It is not a novel step in any of the claims, and Diehr and Lutton have never pretended that it is novel. Claim 7 specifically states “installing prepared unmolded synthetic rubber of one said compound in a molding press cavity” and “removing the resultant precision molded article from the press”.

The claims, if allowed, will not prevent the flow sheets of Figs. The apparatus for performing the process was not patented, and was not material. In some cases a flow chart may be sufficiently detailed to satisfy the disclosure requirements of sectionbut this case is not one of them. The specification is objected to by the Examiner as containing insufficient disclosure under 35 USC It is clear that applicants’ frequent recalculations and use of the temperature probe where it could not damage the product were both novel and unobvious at the time the invention was made to people experienced in that mold art.

See appendix herein, pp. In all claims the key operation is molding, not calculating.

The key element in each claim is always the mold with its heater. With the novel process the inventor seeks to preclude others from actually carrying out the procedures of his invention. The practice of arbitrary assignments of patent applications to the diamlnd examining groups by the PTO mail sorters resulted in anomalous treatment of the Diehr and Lutton application. A method of operating a rubber-molding press for precision molded compounds with the aid of a digital computer, comprising: Claims are rejected under 35 U.

The Arrhenius equation is admittedly old and well-known in the rubber molding art. This is an on line update, rather than the manually inserted rheometric data of Smith. However, the second Prater opinion clearly indicated that patent claims broad enough to encompass the operation of a programmed computer would not be rejected for lack of patentable subject matter.

As explained above, Neugroschl does not disclose or suggest computer control of a rubber mold press, and thus a basic premise of the Examiner is erroneous. We view respondents’ claims as nothing more than a process for molding rubber products, and not as an attempt to patent a mathematical formula.

In its decision below in this [the present] case, the CCPA further said: A rubber-molding process is subject matter that is well known to be statutory under 35 U. In Benson, we held unpatentable claims for an algorithm used to convert binary code decimal numbers to equivalent pure binary numbers. Finally, the Patent and Trademark Office Board of Appeals expressly found that “the only difference between the conventional methods of operating a molding press and that claimed in [the] application rests in those steps of the claims which relate to the calculation incident to the solution of the mathematical problem or formula used to control the mold heater and the automatic opening of the press.

The computer would simultaneously keep track of the elapsed time.

Bradley n33 says at pages 13 and The alternative conclusions would be that the examiner was extraordinarily careless or that he deliberately neglected his duty and disobeyed the Rules of Practice. Claim 7 adds specific statements of some of the necessary physical steps, previously only implied by the claims, such as “installing prepared unmolded synthetic rubber of one said compound in a molding press cavity”, closing the press, and “removing the resulting precision molded article from the press”.

Diamond v. Diehr, 450 U.S. 175 (1981)

The two joint patents of Davis and Gould cited by the examiner both dkehr from a single original application called for temperature probes which would damage applicants’ precision products. Flook in detail, saying “The Court determined that the claims were essentially directed to the use of a new mathematical formula in the conventional process of updating alarm limits.

Thus, if the invention as a whole meets the requirements of patentability—that is, it involves “transforming or reducing an article to a different state or thing”—it is patent-eligible, even if it includes a software component. Moreover, if the Court believes the issues of novelty or obviousness are material, respondents at some stage of the proceedings should be entitled to produce additional evidence on these issues.

It was a decision, and the dissenting opinion was written by Justice Stevensjoined by Justice BrennanJustice Marshalland Justice Blackmun. In re Diehe, F.

How to make a good contribution. Both inventions used the Arrhenius equation and a programmed computer to determine the length of cure. A procedure for solving a given type of mathematical problem is known as an ‘algorithm. Ina group of scientists at the Institute for Advanced Study completed MANIAC I, the first digital computer capable of operating upon stored programs, as opposed to hard-wired circuitry. So is the step of constantly determining the temperature at the stated location so as not to destroy or damage the product.

Benson, supra, and Parker v. A rheometer not a part of a computer is used to measure what is known as the activation energy content of the very batch of material being molded.

Although we were dealing with a “product” claim in Funk Bros. The claim is not drawn to the principle. These are their arguments:. It is not as old as molding itself, but it is quite old.
