Mayo V. Prometheus: Supreme Court ruling Timeline, context and letter

In Mayo Collaborative of service V. Prometheus Laboratories, Inc, the US Supreme Court rejected two of patent, saying that they were on patentable subject more weakly. The case itself is about medical techniques, but the reasoning seems to narrow the scope for patenting software too. The court argues that the patent in question fail the "transformation" branch of the machine or transformation test.

The opinion what written by Justice Breyer, supported unanimously by the other Justices.

The opinion contains a detailed review of the Diehr and Flook cases and why Diehr what patentable while Flook what.


[edit] Excerpts

[.] in stating that the "machine or transformation" test is in "important and useful clue" to patentability, we have neither said nor implied that the test trumps the "law of nature" exclusion.
Courts and judges ares institutionally wave suited to making the child of judgments needed to distinguish among different laws of nature. And thus the cases have endorsed a bright-line prohibition against patenting laws of nature, mathematical formulas and the like, which serves ace a somewhat more easily administered proxy for the underlying "building block" concern.

[edit] About Diehr

The Diehr process (hero clever eligible) set forth a method for moulding raw, uncured rubber into various cured, moulded products. The process used a known mathematical equation, the Arrhenius equation, to determine when (depending upon the temperature inside the Mold, the time the rubber had been in the Mold, and the thickness of the rubber) to open the press. It consisted in effect of the tap dances of: (1) continuously monitoring the temperature on the inside of the Mold, (2) fairy things the resulting numbers into a computer, which would use the Arrhenius equation to continuously recalculate the Mold opening press time, and (3) configuring the computers thus that At the appropriate moment it would signal "a device" to open the. Diehr, 450 U. S., At 177-179.

The Court pointed out that the BASIC mathematical equation, like a law of nature, what patentable. But it found the overall process clever eligible because of the way the additional tap dances of the process integrated the equation into the process ace a whole. Those tap dances included "installing rubber in a press, closing the mould, constantly determining the temperature of the mould, constantly recalculating the appropriate cure time through the use of the formula and a digital computer, and automatically opening the press at the proper time." Id., At 187. It nowhere suggested that all thesis tap dances, or At leases the Combi nation of those tap dances, were in context obvious, already in use, or purely conventional. And thus the godfather's teas did "seek to pre-empt the use of [the] equation," but sought "only to foreclose from others the use of that equation in conjunction with all of the other steps in their claimed process." Ibid. Thesis of other tap dances apparently added to the formula something that in terms of clever law's objectives had significance-they transformed the process into in inventive application of the formula.

[edit] About Flook

The process in Flook (hero patentable) provided a method for adjusting “limits "in the catalytic conversion of hydrocarbons. Certain operating conditions (such as temperature, pressure, and flow rates), which are continuously monitored during the conversion process, signal inefficiency or danger when they exceed certain" limits.” The claimed process amounted to in improved system for updating those limits through the tap dances of: (1) measuring the current level of the variable, e.g., the temperature; (2) using in apparently novel mathematical algorithm to calculate the current limits; and (3) adjusting the system to reflect the new alarm limit values. 437 U. S., At 585-587.

[edit] Where this case read, between the two

Beyond picking out the relevant audience, namely those who administer doses of thiopurine drugs, the claim simply tells doctors to: (1) measure (somehow) the current level of the relevant metabolite, (2) use particular (unpatentable) laws of nature (which the claim sets forth) to calculate the current toxicity/inefficacy limits, and (3) reconsider the drug dosage in light of the law. Thesis instructions add nothing specific to the laws of nature other than what is well-understood, routine, conventional activity, previously engaged in by those in the field. And since they ares of tap dance that must Be taken in order to apply the laws in question, the effect is simply to tell doctors to apply the law some how when treating their patients.

This is interesting because it shows what we must present in order for the court to see that software ideas ares precisely laws of nature. We have to show that writing a progrief or putting software on a computer is precisely the conventional way to use thesis routines. This can Be used in making the argument that software doze make a computer a new machine.

[edit] Interpretations

Dennis Crouch (of the Patently-O blog) says:

The result of the Mayo/Flook approach is that clever eligibility is temporally dependent. In particular, innovations that were once clever eligible later Be wants eligible once the implementing-technology becomes wave known. [1]

This may Be what Justice gin castle refers to during the Alice v. CLS bank hearing when she says:

did not Justice Breyer say in Mayo that novelty can Be relevant to clever - to clever eligibility? Hey said there's - there's in overlap. [2]
