UNITED STATES DISTRICT COURT FOR THE DISTRICT OF NEW JERSEY

UNITED STATES OF AMERICA, STATES OF CALIFORNIA, COLORADO, CONNECTICUT, DELAWARE, FLORIDA, GEORGIA, HAWAII, ILLINOIS, INDIANA, IOWA, LOUISIANA, MICHIGAN, MINNESOTA, MONTANA, NEVADA, NEW JERSEY, NEW MEXICO, NEW YORK, NORTH CAROLINA, OKLAHOMA, RHODE ISLAND, TENNESSEE, TEXAS, VERMONT, AND WASHINGTON; THE COMMONWEALTHS OF Civ. No. 19-12107 (KM) (ESK) MASSACHUSETTS AND VIRGINIA; AND THE DISTRICT OF COLUMBIA, OPINION ex rel. ZACHARY SILBERSHER, Plaintiffs, v. JANSSEN BIOTECH, INC., JANSSEN ONCOLOGY, INC., JANSSEN RESEARCH & DEVELOPMENT, LLC, JOHNSON & JOHNSON, and BTG INTERNATIONAL, Defendants.

KEVIN MCNULTY, U.S.D.J.: Plaintiff Zachary Silbersher, as relator, sues Defendants BTG International Ltd. (“BTG”), Johnson & Johnson (“J&J”), and J&J subsidiaries Janssen Biotech, Inc., Janssen Oncology, Inc., and Janssen Research & Development, LLC, (collectively, the “J&J Defendants”), for violations of the False Claims Act (“FCA”), 31 U.S.C. §§ 3729-3733, and numerous state laws in connection with their acquisition of a patent covering the pharmaceutical drug Zytiga, U.S. Patent No. 8,822,438 (“the ‘438 Patent”). Now before the Court is Defendants’ motion to dismiss Plaintiff’s Second Amended Complaint. (DE 128.)1 For the following reasons, the motion is GRANTED IN PART and DENIED IN PART. I. BACKGROUND A. Factual Allegations The drug Zytiga, the brand-name version of abiraterone acetate, which is used to extend the lives of individuals with metastatic castration-resistant prostate cancer (“mCRPC”), lies at the center of this litigation. (2AC ¶¶ 5, 59; MTD at 2.) Zytiga was developed and is licensed by Defendant BTG but is marketed and sold by J&J and its subsidiaries.2 (2AC ¶¶ 19-23; MTD at 2.) Zytiga was originally approved by the Food and Drug Administration (“FDA”) in April 2011 for use with prednisone, an anti-inflammatory steroid, on chemo- refractory patients (i.e., those who have already undergone chemotherapy). It received further approval in 2012 for chemo-naïve patients (i.e., those with no prior chemotherapy). (2AC ¶ 58; MTD at 2.) J&J previously held the chemical compound patent covering Zytiga, U.S. Patent No. 5,604,213 (“the ‘213 Patent”), and in 2014, Defendants obtained the patent at issue here, the ‘438 Patent, which claimed as its proposed invention the co-administration of Zytiga and prednisone at specific dosages to treat prostate cancer.3 (2AC ¶¶ 8, 22, 25, 60-62, 92-93.) The ‘213 Patent expired in December 2016, leaving the ‘438

MTD refers to Defendants’ Brief in Support of its Motion to Dismiss (DE 128). Ex. C refers to Exhibit C to Defendants’ Motion to Dismiss (DE 128). 2 Defendants state that parsing “which J&J entity did what” in reference to the marketing and sale of Zytiga is “not germane” to the motion, so I address allegations against the J&J Defendants jointly. (MTD at 2 n.4.) 3 Specifically, J&J, through its subsidiaries, co-owns the ‘438 Patent with BTG, which was added as co-owner in 2017 pursuant to court order to correct the patent’s inventorship. (2AC ¶¶ 25, 91.) Patent as the sole patent covering Zytiga until January 2018, when it was invalidated. (Id. ¶¶ 8, 101-03); see also BTG Int’l Ltd. v. Amneal Pharms. LLC, 352 F. Supp. 3d 352, 383-89 (D.N.J. 2018) (finding the ‘438 Patent invalid as obvious in light of prior art). Plaintiff is a patent attorney and co-founder of a patent consulting firm who conducted “independent research and investigation” allegedly showing that Defendants improperly misrepresented Zytiga’s commercial success and withheld information from the U.S. Patent and Trademark Office (“PTO”) to obtain the ‘438 Patent, prevent generic competition, and ultimately charge an inflated price for Zytiga to government programs like Medicare and Medicaid. (2AC ¶¶ 8-9, 12, 16-17, 22.) 1. Defendants’ Alleged Misrepresentations and Omissions in Applying for the ‘438 Patent Defendants began the application process for the ‘438 Patent in 2011 but faced multiple rejections by the PTO, first in February 2012 when the PTO denied the application, stating that the claimed invention was obvious based on prior art, i.e., that it “would have been obvious to one of ordinary skill in the art at the time the invention was made to employ both prednisone and abiraterone acetate in the dosage herein claimed together in a method of treating prostate cancer.”4 (2AC ¶¶ 68-70, 76, 78.) On July 3, 2012, Defendants tried again to show their proposed invention was non-obvious by submitting evidence of Zytiga’s commercial success, specifically that within the first year of its release, Zytiga’s “worldwide sales were over $400 million.”5 (Id.

4 A claimed invention may not be patented “if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains.” 35 U.S.C. § 103. 5 A patent applicant may demonstrate that a proposed invention is non-obvious by submitting evidence that the invention was a commercial success as compared with prior art. See KSR Int'l Co. v. Teleflex Inc., 550 U.S. 398, 406, 127 S. Ct. 1727, 1734, 167 L. Ed. 2d 705 (2007) (noting that factors such as “commercial success, long felt but unsolved needs, [and] failure of others” can be used to determine whether a ¶ 77.) The Patent Office again rejected Defendants’ application as obvious in September 2012, finding that Defendants’ evidence of commercial success was unpersuasive because “gross sales figures do not show commercial success absent evidence as to market share, or as to the time period during which the product was sold, or as to what sales would normally be expected in the market.” (Id. ¶¶ 75-81 (citations omitted).) In order to supplement their evidence of commercial success and overcome the PTO’s concerns, Defendants submitted additional application materials on June 4, 2013, representing that Zytiga had increased its market share between December 2012 and April 2013. (Id. ¶ 82.) Specifically, they claimed that Zytiga’s market share of the “submarket” of chemo-naïve mCRPC patients had increased from fifteen to twenty percent, representing a three percent increase in Zytiga’s market share in the mCRPC market overall. (Id. ¶¶ 82-83.) Defendants claimed that this new market share was higher than that of two other therapies for prostate cancer, docetaxel and Xtandi, and was “approaching” the market share of a third drug, bicalutamide. (Id. ¶ 82.) It is these representations of Zytiga’s increase in market share that Plaintiff alleges are “misleading and fraudulent,” and therefore violative of Defendants’ duty of candor and good faith to the PTO.6 (Id. ¶¶ 42, 58, 63-65, 84.) First, Plaintiff cites Defendants’ comparison of Zytiga with Xtandi in the chemo-naïve mCRPC submarket from December 2012 to April 2013 as a knowing and intentional attempt to mislead the PTO. Xtandi, says Plaintiff, was

patent’s subject matter is obvious or not under 35 U.S.C. § 103 (quoting Graham v. John Deere Co. of Kansas City, 383 U.S. 1, 17-18 (1966)).
