The Board of Appeals erroneously said Pet. A method of operating a rubber-molding press for precision molded compounds with the aid of a digital computer, comprising:.

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

In Flook, the algorithm was expressed in a newly developed mathematical formula; in this case, the algorithm makes use of a well known mathematical formula. Within the Federal Government, pattern of decision have also emerged. Our reasoning in Flook is in no way inconsistent with our reasoning here. In In diehe McIlroy, 58 C. The Patent Office guidelines were based primarily upon the “mental steps” doctrine and the Cochrane v.

Benson and came to the conclusion that in Benson: To avoid this disaster, the general practice was to deliberately attempt overcure, at the expense of production and some product quality. We recognize, of course, that, when a claim recites a mathematical formula or scientific principle or phenomenon of naturean inquiry must be made into whether the claim is seeking patent protection for that formula in the abstract.

Although Diehr and Lutton use thermostats for rough control of the temperature range, they also provide for measuring the actual temperature in the closed press through use of a thermocouple and for doing so continuously. One computer can be used for many such presses — fifty or more.

Applicants have the earlier date, and therefore are filing the affidavit anyway. Sippl, Computer Dictionary and Handbook 23 2d ed. This very novel process is quite important. Respondents’ application contained 11 different claims. It then calls for “repetitively calculating in the computer, at frequent intervals during each cure, the Arrhenius equation.


The rule that the discovery of a law of nature cannot dieehr patented rests not on the notion dieur natural phenomena are not processes, but rather on the more fundamental understanding that they b not the kind of ‘discoveries’ that the statute was enacted to protect.

A process for diebr and curing synthetic rubber oil seals and other precision products would normally be considered a “process” of the type stated in 35 U.

Although their process employs a well-known mathematical equation, they do not seek to preempt the use of that equation, except in conjunction with all of the other steps in their claimed process. The Goodyear Patent is a classical example. The threshold question of whether such a method is patentable subject matter remains. A fixed step-by-step procedure for accomplishing a given result; usually a simplified procedure for solving a complex problem, also a full statement of a finite number of steps.

Claim 1 is quoted in full in n 5 of the Court’s opinion, ante at A method of manufacturing precision molded articles from selected synthetic rubber compounds in an openable rubber molding press having at least one heated precision mold, comprising:. If the Court were to decide that such a computer program is patentable, it would not decide this case.

Judge Kirkpatrick, joined by Chief Judge Worley, wrote a vigorous dissent objecting to the majority’s decision to abandon “a rule which is about as solidly established as any rule of the patent law. Hence, the prior- art calculations of proper cure time were based on guesswork and could not be accurate. These additional steps, we recently explained, “transformed the process didhr an inventive application of the formula.

The Court interpreted Diehr slightly differently in Alice v. The answer is clearly yes. They can program their computers by it, and Federal-Mogul would have no right to sue — unless they practice the rubber molding process.

As now claimed, the applicants’ method provides a very efficient control for the press, far more efficient than either the analog routine of Gould or the complex routine of Smith.

The majority dismissed Benson with the observation that Benson involved only process, not apparatus, claims. The type of flow chart in the instant application is not detailed enough to place an operative program within the hands of those skilled in the art.


The examiner made dehr final rejection in the second application, S. 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. A “cure” is obtained by mixing curing agents into the uncured polymer in advance of molding, and then applying heat over a period of time.

Diamond v. Diehr – Wikipedia

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. The “novelty” of any element or steps in a process, or even of the. As noted in col. It is not a novel step in any of the claims, and Diehr and Lutton have never pretended that it is novel.

Their method of updating the curing time calculation is strikingly reminiscent of the method of updating alarm limits that Dale Flook sought to patent. It is an act, or a series of acts, performed upon the subject matter to be transformed and reduced to a different state or thing. Second, the inclusion of the ambiguous concept of an “algorithm” within the “law of nature” category of unpatentable subject matter has given rise to the concern that almost any process might be so described, and therefore held unpatentable.

Invention was recognized because Laitram’s assignors combined ordinary elements in an extraordinary way — a novel union of old means was designed to achieve new ends. Claim 5 has been amended to cover a “method of operating a plurality of rubber-molding presses simultaneously curing precision molded compounds in conjunction with a computer. In its report, the President’s Commission stated:.

You can edit it. The inventors used it to refine a physical step in the process in a manner analogous to the manner in which mathematics and physical laws were employed in the inventions in Mackay Radio n25 and Eibel Process Co.
