Respondents agree, while still remarking that this step is, indeed, one of the novel portions of the claimed process. Constant recalculations along with continuous determinations of the actual temperatures, is the key feature here, not the equation or the fact of calculation.
The method of claim 3 diamonv the frequent periodic interval is approximately 10 seconds. By that standard there can be no doubt that Diehr and Lutton seek to patent a process, not an algorithm for a computer nor the idea itself. The Solicitor General states in the brief at page These recurring long chains impart the elasticity, tensile strength, deformability, and hardness found in both natural and synthetic rubber.
Diamond v. Diehr, 450 U.S. 175 (1981)
See also In re Deutsch, F. The computer would simultaneously keep track of the elapsed time. Final rejection July 8, In re Walter, F. Where the product is overcured there is deterioration in the quality of the product and the press is needlessly tied up, so that production is reduced.
None of this money came from the sale or license of a computer program. To diamonf this disaster, the general practice was to deliberately attempt overcure, at the expense of production and some product quality.
In some cases a flow chart may be sufficiently detailed to satisfy the disclosure requirements of section diamoond, but this case is not one of them.

Please check official sources. There are instruments available which will indicate, record or control all the services involved in vulcanisation, including time, temperature and pressure, and are capable of setting in motion diamonnd operations as the opening and closing of moulds and, in general, will control any process variable which is capable of being converted into an electric charge or pneumatic or hydraulic pressure impulse.
From the generic formulation, programs may be developed as specific applications. Claim 6 has been added to follow claim 1. New patent applications are sent to a special group of intelligent sorters constituting what is termed the Application Division. Although applicant has provided a flow chart, it is noted that such flow chart diamonnd not a program and only suggest [sic] operations from the point of view of desired results.
We think this statement in Mackay takes us a long way toward the correct answer in this case. In Flook, this Court clarified Benson in three significant respects. They depend from claim 1 which is now thought to define patentable subject matter, and thus they are thought allowable.
Diamond v. Diehr – RESPONDENTS’ BRIEF ON THE MERITS
The two joint patents of Davis and Gould cited by the examiner both stemming from a single original application called for temperature probes which would damage applicants’ precision products. The starting point in the proper adjudication of patent litigation is an understanding of what the inventor claims Page Fiamond. Thus, this case falls squarely within the holding in Flook, and the claims must be held to be non- statutory.
In determining priority of invention there shall be considered not only the respective dates of conception and reduction to practice of the invention, but also the reasonable diligence of one who was first to conceive and last to reduce to practice, from a time prior to conception by the other. It has a data storage bank of suitable size which, of course, may vary when many molds are used and when more refinements are employed.
Did not include Figs. Therefore, reexamination and reconsideration is respectfully requested. Articles with short description. As in Chakrabarty, we must here construe 35 U. One computer can be used for many such presses — fifty or more. The invention’s history in the Patent and Trademark Office was irrelevant to the hearing before the Board of Appeals and to the hearing before the Court of Customs and Patent Appeals. FlookU. The patent application at issue was filed on August 6, by James R.
Using this formula, the updated alarm limit could be calculated if several other variables were known. Three examples are claims 1, 2, and It has long been used for calculating the curing time for rubber compounds.
Flook and Gottschalk v. In Flook, the Court’s analysis of the post-solution activity recited in the patent application turned not on the relative significance of that activity in the catalytic conversion process, but rather on the fact that that activity was not a dizmond of the applicant’s discovery:.
The instant invention is disclosed and claimed to be one involving a general purpose digital computer properly programmed to calculate the correct cure time for a rubbermolding press and to open such press accordingly.
But the Court carefully avoided overruling Benson or Flook. These are their arguments:.
Diamond v. Diehr – Wikipedia
Flook as resting on nothing more than the way in which the patent claims had been drafted, and it expressly declined to use the method of claim analysis spelled out in that decision. The calculations are the beginning and the end of the claims.
It is not as old as molding itself, but it is quite old. As the numerous briefs amicus curiae filed in Gottschalk v. Before this Court decided Flook, however, the lower court developed a two-step procedure for analyzing program-related inventions in light of Benson.
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. Skip to main content. It has been so considered for more than years. These affirmances and reversals are not whimsical or arbitrary; they are based on sound application of sound principles set forth by this Court in Flook, Benson, and a long line of cases going back to Cochrane v.
According to the respondents, the continuous measuring of the temperature inside the mold cavity, the feeding of this information to a digital computer which constantly recalculates the cure time, and the signaling by the computer to open the press are all new in the art. See Appendix A, p. 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.
The Supreme Court upheld the patent.
