Opinion

EDWARD M. CHEN, United States District Judge

Plaintiff Medical Diagnostics Labs alleges that Defendant Protagonist Therapeutics, Inc.'s development of a drug called PTG-200 infringes on its patent for polypeptides that bind to IL-23 receptors. These polypeptides, including PTG-200, have therapeutic potential to treat inflammatory and autoimmune diseases. Protagonist has entered into a multi-million dollar agreement with third-party pharmaceutical company Janssen, Inc. to develop the drug, perform testing necessary for regulatory approval, seek regulatory approval, and, if regulatory approval is obtained, to manufacture and commercialize the drug.

Defendant moves to dismiss, arguing that the activities alleged in the complaint all fall under the safe harbor provided by 35 U.S.C. § 271(e)(1). For the reasons below, the Court agrees that all activity alleged-with the exception of future commercialization plans-falls within the safe harbor provision. Insofar as future commercialization may infringe on Plaintiff's patent, however, the issue is not sufficiently concrete or immediate to create a case-or-controversy because several contingencies may never materialize. Thus, the Court GRANTS Defendant's motion to dismiss.

I FACTUAL BACKGROUND

Plaintiff Medical Diagnostic Labs ("MDL"), a reference laboratory, alleges patent infringement by Defendant Protagonist Therapeutics ("Protagonist"), a pharmaceutical company that develops peptide-based chemicals for therapeutic purposes.

MDL owns U.S. Patent No. 8,946,150 ("the '150 patent"), which covers "novel polypeptides that bind to IL-23 receptor and inhibit the binding of IL-23 to its corresponding receptor and cell signaling thereof" and their "use" "to treat IL-23 associated human diseases including, for example, inflammatory bowel diseases, psoriasis and Crohn's disease." Compl. ¶¶ 11-12. These peptides have therapeutic potential, id. ¶ 15, which, of course, translates to commercial potential, as "over 10 million people in the United States are affected by IL-23 mediated immune-diseases." Id. ¶ 17.

In 2011, MDL filed provisional application No. 61/520,710 ("the '710 application") "covering its IL-23 receptor inhibitor technology." Id. ¶ 16. In 2012, it filed U.S. Application No. 13/523,286 ("the '286 application"), which claims priority to the '710 application. The '286 application published on January 31, 2013 as US 2013/0029907 ("the '907 publication"), and issued as to the '150 patent on February 3, 2015. Id.

*1246On July 17, 2014, Defendant Protagonist filed provisional application No. 62/025,899 ("the '899 application"), called "Oral Peptide Inhibitors of Interleukin-23 Receptor and Their Use to Treat Inflammatory Bowel Diseases." The '899 application references MDL's '907 publication. Id. ¶ 19.

A few months later, in October 2014, scientists from both companies met, during which time MDL shared information about its IL-23 polypeptide research with Protagonist. Id. ¶ 20. On February 3, 2015, MDL's '286 patent issued. Id. ¶ 21. Two days later, Protagonist sent MDL a nondisclosure agreement so the parties could continue discussing their research. Id. ¶ 21. On February 23, Protagonist filed two new provisional applications relating to IL-23 (the '685 and '688 applications). Id. ¶ 22. The parties signed the non-disclosure agreement on May 5, 2015, and then held a telephonic conference regarding MDL's IL-23 research on May 29, 2015. Id. ¶¶ 25-26. On July 15, 2015, Protagonist filed its '627 application (which later issued as the '268 patent), containing significantly more amino acid sequences than its earlier July 2014 '899 provisional application. Id. ¶ 27.

Between July 15, 2015 and October 13, 2015, the parties attempted but failed to negotiate a licensing agreement for Protagonist under MDL's patent. Id. ¶¶ 28-30.

Then things took off for Protagonist. After an initial public offering in 2016, Protagonist began publicly announcing in early 2017 its research into PTG-200, a polypeptide hoped to have inhibiting effects on IL-23 receptors. Id.
