Escape from Prometheus?


Patent Docs has a post on the July 21 decision in MOMENTA PHARMACEUTICALS v. AMPHASTAR PHARMACEUTICALS, INC., 2017 U.S. Dist. LEXIS 113713 (earlier decision in June 2017 U.S. Dist. LEXIS 101125).

The issue is [patentee] Momenta's motion for judgment as a matter of law

The opinion is short, with the key points:



The two-step framework for patentable subject [*6] matter is described in Mayo Collaborative Servs. v. Prometheus Labs., Inc., 566 U.S. 66, 132 S. Ct. 1289, 1293, 182 L. Ed. 2d 321 (2012). First, the Court must determine whether the patent claims are "directed" to a patent-ineligible concept, such as a natural law, natural phenomenon or abstract idea. Rapid Litig. Mgmt. Ltd. v. CellzDirect, Inc., 827 F.3d 1042, 1047 (Fed. Cir. 2016) (quoting Mayo, 132 S. Ct. at 1296-97). If the claims are not so directed, they are patentable. Id. If the claims are directed to an ineligible concept, then the Court determines whether the elements of the invention "transform" the claims into an application eligible for a patent. Id. Patent eligibility is a question of law. Id.

Because the '886 patent "[is] directed to a new and useful method" of ensuring the quality of enoxaparin and involves a series of laboratory steps rather than a law of nature or abstract idea, this Court concludes that the asserted claims involve patentable subject matter. See CellzDirect, 827 F.3d at 1048. Therefore, with respect to the affirmative defense that the asserted claims do not involve patent eligible subject matter, Momenta's motion will be allowed.

With respect to the indefiniteness defense, a patent's specification must be sufficiently "definite" so as to include at least one claim that "particularly point[s] out and distinctly claim[s] the subject matter which the applicant regards as [the] invention." 35 U.S.C. § 112 (2002). Pursuant to Nautilus, Inc. v. Biosig Instruments, Inc., 134 S. Ct. 2120, 2124, 189 L. Ed. 2d 37 (2014),
[a] patent [*7] is invalid for indefiniteness if its claims, read in light of the specification delineating the patent, and the prosecution history, fail to inform, with reasonable certainty, those skilled in the art about the scope of the invention.

Although "[s]ome modicum of uncertainty" is permissible, the "patent must be precise enough to afford clear notice of what is claimed." Trusted Knight Corp. v. Int'l Bus. Machines Corp., No. 2016-1510, 2017 U.S. App. LEXIS 3979, 2017 WL 899890, at *3 (Fed. Cir. Mar. 7, 2017) (quoting Nautilus, 134 S. Ct. at 2128-29).

When a Court evaluates indefiniteness by examining intrinsic evidence, such as the claims and specifications in the patent, indefiniteness is a question of law. Biosig Instruments, Inc. v. Nautilus, Inc., 783 F.3d 1374, 1378 (Fed. Cir.), cert. denied, 136 S. Ct. 569, 193 L. Ed. 2d 431 (2015).
Amphastar contends that all of the claims are indefinite because they are limited to "the non naturally occurring sugar associated with peak 9 of FIG. 1" and there is no specific "FIG. 1" in the '886 patent. Based on the intrinsic evidence, however, the "Figure 1" in the patent is composed of Fig. 1A and Fig. 1B. The only figure in the patent with peak 9 is FIG. 1A. Moreover, the claims of the patent involve enoxaparin and the Fig. 1A is titled "Lovenox" which is the brand name for enoxaparin. Furthermore, the "Brief Description of the Drawings" in the patent clarifies that FIG. 1A is a "[c]apillary electrophoresis (CE) profile of enoxaparin (Lovenox™)". Therefore, [*8] this Court concludes that the patent "afford[s] clear notice of what is claimed." Trusted Knight Corp., 2017 U.S. App. LEXIS 3979, 2017 WL 899890, at *3 (quoting Nautilus, 134 S. Ct. at 2128-29) and, with respect to the infiniteness defense, the motion for judgment as a matter of law with be allowed
