Prometheus Patents Struck Down, 9-0: Mayo Collaborative Services v. Prometheus Laboratories, Inc. Analysis

In a strong rebuke to the Federal Circuit, a unanimous U.S. Supreme Court held (pdf), on March 20, 2012, that Prometheus Laboratories’ claims to methods of administering drugs to treat gastrointestinal autoimmune diseases do not meet the patentable subject matter standard of section 101 of the Patent Act.  The representative claim quoted by the Court recites, “A method of optimizing therapeutic efficacy for treatment of an immune-mediated gastrointestinal disorder” comprising two steps: (a) administering one of a class of drugs (thiopurines) and (b) determining the level of a specified metabolite, “wherein” a level below a given threshold “indicates a need to increase the amount of said drug subsequently administered” [to improve efficacy], and a level above the threshold “indicates a need to decrease the amount of said drug subsequently administered” [to avoid toxicity].

History of the Case. Mayo originally bought and used Prometheus test kits that employed the patented method, but it then decided to sell and market its own test, which was similar, but not identical.  Prometheus sued for patent infringement.  The district court found that Mayo’s test would infringe the Prometheus patents, but it then held the patents invalid as essentially claiming unpatentable laws of nature–in this case, the relationship between the levels of the specified metabolite and the efficacy or toxicity of the relevant drugs.

Classen: Has the Federal Circuit Lost Interest in Patentable Subject Matter?

Allison Williams Dobson is an attorney, scientist and lecturer in the Norfolk, Virginia area and is a regular GLR contributor.

But First: The Federal Circuit Has Denied the Plaintiff’s Motion for Rehearing in Myriad: This week, the Federal Circuit issued a one-word order—“Denied”—turning down both parties’ requests for rehearing by the three-judge panel that decided that case originally. The parties now have 90 days to file a certiorari petition asking for Supreme Court review.

This news is not surprising considering the Federal Circuit’s most recent treatment of patent-eligible subject matter under § 101 of the Patent Act. On August 31, 2011, another 2-1 divided panel issued its opinion (three very strong opinions, really) in Classen Immunotherapies, Inc. v Biogen Idec (pdf).

The majority finds that two of the three method patents in dispute claim subject matter that is patent-eligible under § 101. However, the court also emphasizes repeatedly that the two patents “may not” meet the other requirements for patentability imposed by §§ 102 (novelty), 103 (nonobviousness), and/or 112 (adequate written description). The thrust of the majority’s message is becoming a familiar mantra–the statutory role of § 101 is to act as a “coarse eligibility filter”–a gateway to the real tests–and not the “final arbiter of patentability.”

Prometheus Returns to the Supreme Court, Medical Method Patent Speculation Intensifies

While everyone has been busy speculating about whether the Supreme Court will ultimately take the Myriad case, the justices (at least four of them—see below) sprung a surprise this week by deciding to review the Federal Circuit’s decision in another biomedical patent case, Prometheus v. Mayo.

The patents at issue in Prometheus involve a method of administering a drug (specifically thiopurine drugs used to treat gastrointestinal and other autoimmune diseases), measuring the drug’s level in a patient’s body, and then adjusting the dosage of the drug. The Supreme Court will hear the case this fall and should (see below) issue a ruling by next summer, thus drawing to a close a legal journey that began more than three years ago in a California district court.

Prometheus Unbound—Again

The latest news from the field of biotechnology patents is in: the Federal Circuit has handed down its opinion (again) in Prometheus v. Mayo (pdf), the closely watched diagnostic method case. The verdict is the same as before: Prometheus’s patents satisfy the § 101 test for patentable subject matter.

On Monday, we wrote about the Federal Circuit’s first post-Bilski method patent decision: Research Corporation Technology v. Microsoft. In analyzing RCT we argued that it was “a good bet that the Prometheus and Myriad patents, and others like them, will survive § 101.” That bet paid off today in Prometheus and, based on the signals the Federal Circuit sent in that opinion, we think it is increasingly likely to pay off again in Myriad in the form of at least a partial reversal (more on this below).

Applying Bilski means Business as Usual. Way back in June, when the Supreme Court decided Bilski, it not only failed to provide lower courts (including the Federal Circuit) with meaningful guidance for biotechnology method patents, it arguably failed to provide meaningful guidance about anything at all. Despite predictions that Bilski might fundamentally reshape the patent landscape, the Court’s fractured opinions produced little in the way of binding law. The clearest statement from the Court was that the machine-or-transformation test for method patentability, which the Federal Circuit had previously deemed an exclusive test, was in fact only a “useful and important tool.” (Other useful and important tools were not, however, enumerated.)

A Hint About Where the Federal Circuit Is Going with Method Patents?

GLR readers will recall that just last summer the Supreme Court passed-up a major opportunity to clarify the status of method or process patents. The patentability of business methods, computer-implemented processes, and diagnostic and other medical methods has long been both controversial and uncertain. In Bilski v. Kappos, the Court confronted a method for hedging against fluctuations in commodities prices. All nine justices thought the method was too abstract to comprise patentable subject matter as defined in section 101 of the Patent Act, but they couldn’t agree on why. The five-member majority held that the machine-or-transformation test (which states that the method must be tied to a particular machine or change something into a different state) propounded by the Federal Circuit in its initial Bilski decision could not be the exclusive test for patentability, but it failed to come up with a test of its own.

The day after issuing its decision in Bilski, the Supreme Court dealt, temporarily, with another closely watched case, Prometheus v. Mayo. In Prometheus, the Federal Circuit used Bilski’s machine-or-transformation test to uphold a method for administering a drug, measuring its level in the body, and then adjusting the dosage. The Supreme Court granted certiorari in Prometheus, as well as in a similar biotechnology method case (Classen Immunotherapies v. Biogen IDEC), and then immediately vacated both decisions and remanded the cases to the Federal Circuit for reconsideration in light of Bilski. Neither of those decisions have yet been issued by the Federal Circuit.
