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

The term “computer program” — a term ill-defined in the Commissioner’s brief — should not be a shibboleth to decide the outcome of this case or of others like it. It manufactures metal bearings tapered roller bearings, ball bearings, journal bearingsand synthetic rubber shaft seals. Natural rubber had few uses unti Charles Goodyear discovered and patented the process he called “vulcanization”, now usually referred to as “cure”. The case does present eleven claims in a patent application.


Deihr patent application at issue was filed by the respondents on August 6, Three examples are claims 1, 2, and 11, which provide: In In re Johnston, F. Hence, the “Question Presented” by this case should be accurately defined. 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.

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. The legislative history of the Patent Act is in accord with this reasoning. The question, therefore, of whether a particular invention is novel is “wholly apart from whether the invention falls into a category of statutory subject matter.


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 siehr the inventions in Mackay Radio n25 and Eibel Process Co. The first step is dieyr determine whether the claims involve mathematical calculations.

From Wikipedia, the free encyclopedia. In re Noll, F. These elements are not the abstract mathematical formula considered in the cited Gottschalk v. He discovered that an apparent accident had drastically changed — and improved — the rubber latex.

In the Dianond and Lutton claims; “the calculation is intimately entwined with the rubber molding process recited. In the Examiner’s Answer g the appellants’ brief before the Board of appeals, the examiner stated: If that method is regarded as an “algorithm” as that term was used in Glottschalk v.


Rather, this number is then compared to the elapsed time since the mold was closed to determine if they are the same. The remaining steps — installing rubber in the press and the subsequent closing of the Page U. The Commissioner’s brief says that dlehr question is: About It’s a pool of information, not a statement of ESP’s views or policiesso no permission is required.

Although each time the computer solves the Arrhenius equation, a number is obtained; unlike Flook, that number is not the end product of the claim. The court upheld a patent on a way to use rubber-curing machinery, controlled by a computer. Another cause of cure inaccuracy is the way thermostats work. Federal-Mogul applied for a patent in order to be in a position where it might receive reasonable royalties from licensed users.

Gottschalk, Dann, Parker, and Diamond were not ordinary litigants — each was serving as Commissioner of Patents and Trademarks when he opposed the availability of patent protection for a program-related invention. The type of flow chart in the instant application f not detailed enough to place an operative program within the hands of those skilled in the art. It summed up its view of the Diehr and Lutton claims this way:.

See also In re Deutsch, F. The sole practical application of the algorithm was in connection with the programming of a. It did criticize the analytic methodology of Flookhowever, by challenging its use of analytic dissectionwhich the Flook Court based on Neilson v. And another may invent a labor-saving machine by which this operation diamlnd process may be performed, and each may be entitled to his patent.

The Court repeated its earlier holding that mathematical formulas in the abstract are not eligible for patent protection. Opinion Announcement – March 03, However, a careful review of Neugroschl establishes that the computer disclosed therein provides no control of the molding press whatsoever.
