Opinion

OPINION AND ORDER

WILLIAM M. CONLEY, District Judge.

This patent dispute presents a question of first impression with respect to the subject matter eligibility of a urine or other biological sample for drug screening and compliance protocols under 35 U.S.C. § 101, as well as related issues of enablement under § 112. The analysis is made more challenging by the state of flux in the treatment of competing goals inherent in § 101 challenges in recent years, and even in recent months. See Mayo Collaborative Services v. Prometheus Laboratories, Inc., [889]*889— U.S. -, 132 S.Ct. 1289, 182 L.Ed.2d 321 (2012); In re BRCA1- & BRCA2-Based Hereditary Cancer Test Patent Litig., 774 F.3d 755 (Fed.Cir.2014); DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245 (Fed.Cir.2014); Ultramercial, Inc. v. Hulu, LLC, 772 F.3d 709 (Fed.Cir.2014). Of course, this debate reflects a broader tension in patent law between what is legitimate invention in need of the incentives of patent law and what is merely description of the natural world for which no further incentive is required than our desire to understand it better — a tension recognized virtually from the outset of the American patent system. See Le Roy v. Tatham, 55 U.S. 156, 159, 14 How. 156, 14 L.Ed. 367 (1852). Justice Breyer’s relatively recent opinion in Mayo attempts to reconcile the goal of ensuring that patents do not “impede innovation more than it would tend to promote it,” and the axiomatic notion that “all inventions, at some level embody, use, reflect, rest upon, or apply laws of nature, natural phenomena, or abstract ideas.” Id. at 1293. Thus, Justice Breyer cautions that “too broad an interpretation of the exclusionary principle could eviscerate patent law.” Id.

Here, plaintiffs Ameritox, Ltd., and Marshfield Clinic, LLC allege that defendant Millennium Health, LLC infringes two of their patents: U.S. Patents No. 7,585,680 (“the '680 patent”), purporting to describe a method for drug screening and compliance protocols for one sample of urine from a patient on a prescribed medication regimen; and 7,785,895 (“the '895 patent”), purporting to describe a similar method for one biological sample generally. (See Am. Compl., Exs. A, B (dkt. ## 106-1, 106-2).) Defendant Millennium seeks summary judgment of non-infringement and invalidity as to both patents. (Dkt. # 126.) The parties also ask the court to construe various terms common to both patents, including most notably “known normative data” and “quantifying the concentration.” (Def.’s Opening Br. (dkt. # 130); Pl.’s Opp’n (dkt. # 172).) For the reasons that follow, the court will deny Millennium’s motion for summary judgment of non-infringement and invalidity with respect to the '680 patent and grant the motion with respect to the '895 patent, finding the patent invalid for lack of enablement under § 112. For many of the same reasons, the court finds the '895 patent is vulnerable to the application of the exclusionary principle under § 101, while the '680 patent is substantially less so.

UNDISPUTED FACTS

I. The Licensing Agreement

Plaintiff Marshfield Clinic is a health care and research organization. Marsh-field is also the assignee of the patents-in-suit from the inventors, Dr. Michael Larson and Dr. Thomas Richards.

Plaintiff Ameritox Ltd. is in the field of pain medication monitoring, including a provider of urine drug testing (“UDT”) services. Ameritox is the exclusive licensee of the patents-in-suit pursuant to an exclusive license agreement between Am-eritox and Marshfield dated March 15, 2010. In exchange for an exclusive license, Ameritox agreed to make certain royalty payments to Marshfield and to use good faith commercial efforts to develop, market, and sell a drug testing service based on the asserted patents.

II. The Testing Protocols

Ameritox tests urine samples on behalf of doctors, nurses, and other health-care providers who prescribe pain medications to treat chronic pain. (Am. Compl. (dkt. # 106) ¶¶ 7.) Ameritox describes its UDT service as being able to “help clinicians assess whether patients are correctly taking medications and whether the prescrip[890]*890tion .should be adjusted.” (Dr. Paul J. Orsulak Infringement Report (“Orsulak Infringement Rept.”) (dkt. # 117) ¶¶ 27.) Healthcare professionals periodically use Ameritox’s services to monitor drug levels in their patients in order to help assess their patients’ therapeutic response to medications and adherence to the treatment plan, as well as to detect aberrant behaviors (e.g., illegal drug use) that may complicate treatment. ('680 patent at 2:17-20.)1

On May 16, 2011, Ameritox launched its current Rx Guardian CD service, which Ameritox asserts is based on the patents-in-suit.2 The testing protocol for Rx Guardian CD has three phases. (Dr. Paul J. Orsulak Rebuttal Report (“Orsulak Rebuttal Rept.”) (dkt. #118) ¶¶ 246-56.) First, Ameritox performs a series of laboratory tests to detect and measure the amount of drug and drug metabolites in a patient’s urine sample (the “detection” steps, which are reflected in steps (a)-(d) of the '680 patent). Second, Ameritox “normalizes” or “adjusts” urine drug levels for a patient’s hydration status by determining the metabolite/creatinine ratio of the patient (the “normalization” step, as reflected in step (e) of the '680 patent).3 Third, the Rx Guardian CD protocol compares a patient’s normalized test results to a range of “normative data” collected from other clinical patients on the same medication, who Marshfield carefully monitored to insure adherence to their prescribed opioid regimen (the “determining” step, as reflected in step (f) of the '680 patent).

By comparing the patient’s normalized value to a range of values for other clinical patients believed to be prescribed and taking the same medication properly, the health care provider can better assess whether a patient is likely to be taking the prescribed drug in a manner consistent with the. prescribed regimen. The three steps outlined above largely truncate the steps outlined in claim 1 of the '680 patent, which states:

1. A method for quantifying at least one metabolite in a biological sample comprising the steps of:
(a) providing one biological sample obtained -from a patient on a prescribed medication regimen, wherein the sample comprises at least one test metabolite, wherein in the sample is urine;
(b) providing one set of known normative data specific to a reference metabolite, wherein the set of data is collected from a population that is on a prescribed medication regimen; [891]*891(c) contacting the biological sample with an analytical device;
(d) detecting the presence of at least one test metabolite in the biological sample with the device, wherein the device is capable of measuring the concentration of the test metabolite in the sample;
(e) normalizing the biological sample to adjust for changes in the patient’s hydration status by determining the metabolite/creatinine ratio of the patient; and
