Sippl, Computer Dictionary and Handbook 23 2d ed. The following description of the vulcanization duehr appears in a text published in Part III, Paragraph 4 Claims are also rejected under Sections and as drawn to non-statutory subject matter. One computer can be used for many such presses — fifty or more. As discussed in U. The patent examiner rejected the respondents’ claims on the sole ground that they were drawn to nonstatutory subject matter under 35 U.

Before the CCPA, Diehr and Lutton vigorously contended for the novelty of each claim as a whole and for the novelty of measuring the temperature in the mold.

The process uses a mold for precisely shaping the uncured material under heat and pressure and dieur curing the synthetic rubber in the mold, so that the product will retain its shape and be functionally operative after the molding is completed. But the shortcoming of this practice is that operating with an uncontrollable variable inevitably led in some instances to overestimating the mold-opening time and overcuring the rubber, and in other instances to underestimating that time and undercuring the product.

Diamond v. Diehr – RESPONDENTS’ BRIEF ON THE MERITS

This assumption was expressly rejected in Flook: Rather, this number is then compared to the elapsed time since the mold was closed to determine if they are the same.

This is the normal and only proper reason for not dirhr a rejection under prior art. None of this money came from the sale or license of a computer program.

The respondents’ claims describe in detail a step-by-step method for accomplishing such, beginning with the loading of a mold with raw, uncured rubber and ending with the eventual opening of the press at the conclusion of the cure.

That is not the question presented to this Court. The Court interpreted Diehr slightly differently in Alice v.

The Board based its conclusions regarding conventionality of the claims on three faulty premises: Any novelty in the dehr, therefore must be based on the particular calculations performed by the computer according to a prescribed program.

Before being molded, the elastomers used in this process are chemical compounds of a type known as polymers. Beginning with two decisions ina dramatic change in the law as understood by the Court of Customs and Patent Appeals took place. How to make a good contribution.

The Commissioner of Patents and Trademarks sought certiorari, arguing that the decision of the Court of Customs and Patent Appeals was inconsistent with prior decisions of this Court. A to Petition, p. Significantly, the Court referred to the patentability of a process for vulcanizing rubber:. In addition to the foregoing reasons distinguishing applicants’ invention from the Smith patent, applicants are filing herewith a Rule affidavit and exhibits by which they establish a conception and reduction to practice of their invention before the effective filing date of the Smith application, being September 1, Flook, with each case discussed and applied at length.

The CCPA also held that the present claims are not directed to a mathematical formula or a method of calculation but to a process or method for molding rubber articles. Excerpt of Joseph D.

Instead, they seek patent protection for a process of curing synthetic rubber. Finally it calls for “opening the press automatically when” the “comparison indicates equivalence.

In Rubber-Tip Pencil Co. The CCPA reversed and held that the subject matter of all eleven claims defined a process within the terms of 35 U. If the synthetic rubber is cured for the right length of time at the right temperature, it becomes a usable product.

But in neither case should that activity have any legal significance, because it does not constitute a part of the inventive concept that the applicants claimed to have discovered. When a patent issues, it is printed, and anyone can get a copy for fifty cents and reproduce any or all pages with impunity.

It distinguished the Diehr process of molding rubber oil seals from inventions like the Walter process in which the claimed physical result was “described in mathematical terms. Respondents characterize their contribution to the art to reside in the process of constantly measuring the actual temperature inside the mold.

The claims involve the employment of a scientific truth to a new and useful end without attempting to control the use of the truth itself.

It is possible, using well-known time, temperature, and cure relationships, to calculate by means of the Arrhenius equation [ Footnote 2 ] when to open the press. PrometheusU. The apparatus for performing the process was not patented, and was not material.

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.

Gould is further distinguished in that Gould relied on an analog computer to calculate cure in terms of “cure units,” each cure unit being defined as the cure obtained at diebr given temperature for one minute Gould, claim 1. Similarly, insignificant post-solution activity will not transform.

In the Examiner’s Answer to the appellants’ brief before the Board of appeals, the examiner stated: In addition, the claimed process has increased productivity by about twenty percent, by eliminating over-curing.

In its more recent decision in In re Walter, F. Significantly, the Court referred to the patentability of a process for vulcanizing rubber: To accept the analysis proffered by the petitioner would, if carried to its extreme, make all inventions unpatentable, because all inventions can be reduced to underlying principles of nature which, once known, make their implementation obvious.
