Purdue Pharma L.P. v. Collegium Pharm., Inc.

Case Name: Purdue Pharma L.P. v. Collegium Pharm., Inc., 15-260-SLR, 2015 U.S. Dist. LEXIS 102899 (D. Del. Aug. 6, 2015) 

Drug Product and Patent-in-Suit: Oxycontin^® (oxycodone); U.S. Patents Nos. 7,674,799 ("the '799 patent"), 7,674,800 ("the  '800 patent"), and 7,683,072 ("the '072 patent")

Nature of the Case and Issue(s) Presented: Purdue, a Delaware corporation and the manufacturer of Oxycontin, was engaged in litigation in the Southern District of New York, where the ’799 and ’800 patents were found to be invalid. Purdue appealed that decision. Meanwhile, Collegium, a Virginia corporation, filed a new drug application seeking to sell "an abuse-deterrent, extended release formulation of oxycodone." Purdue claimed that it was entitled to data exclusivity for Oxycontin’s abuse-deterrent clinical studies until April 2016, prohibiting FDA approval of Collegium’s drug until then. After receiving Collegium’s PIV Certification notice letter, Purdue filed this suit in the District of Delaware. Purdue also filed a protective suit in Massachusetts, and sought to stay all cases until the final decision on appeal regarding the validity of its patents. Collegium moved to dismiss the case for a lack of personal jurisdiction. The District of Delaware agreed, and transferred the matter to the District of Massachusetts.

Why Collegium Prevailed: First, the court addressed general jurisdiction. Because Collegium was not currently incorporated in Delaware, and because Delaware was not Collegium’s principal place of business, Delaware was not a "clear and certain" forum in which Collegium could expect to be sued. Thus, the court did not have general jurisdiction over Collegium.

The court also determined that it did not have specific jurisdiction over Collegium. Collegium did not send its PIV Certification notice letter to Purdue in Delaware. In addition, Collegium was not registered to do business in Delaware. Although the oxycodone that Collegium used in its drug was manufactured in Delaware, oxycodone is a basic API that is subject to multiple patents and available in multiple dosage forms. The court determined that this was insufficient to establish jurisdiction over Collegium. Further, because Purdue’s complaint did not arise from the sale of the oxycodone to Collegium, Collegium did not have a reasonable expectation of being sued in Delaware. Thus, it would be unconstitutional for the court to exercise jurisdiction over Collegium.

Massachusetts, on the other hand, was the appropriate venue for the litigation. Collegium’s headquarters are located in Massachusetts and it conducted business in that state. Thus, the court dismissed the instant action so that Purdue could pursue its protective lawsuit in Massachusetts.
