§§ 1331, 1338(a), 2201 and 2202, because it arises under the patent laws of the United States and the Declaratory Judgment Act. 10. This Court has personal jurisdiction over the Defendants because the Defendants
(a) knowingly transact a large volume of business in Massachusetts, (b) on information and belief, have engaged in, and made meaningful preparations to engage in, infringing conduct in Massachusetts, and (c) have caused, and are causing, injury in Massachusetts by reason of their conduct within and outside of the Commonwealth. 11. Venue is proper in this Court pursuant to 28 U.S.C. §§ 1391(b) and (c) and
1400(b), because (a) this Court has personal jurisdiction over Defendants and (b) on information and belief, Defendants have committed, or made meaningful preparations to commit, acts of infringement in this District. THE MOMENTA PATENTS 12. On August 18, 2009, the United States Patent and Trademark Office (the “PTO”)
lawfully issued the '886 patent, entitled “Analysis of Sulfated Polysaccharides.” A true copy of the '886 patent is attached hereto as Exhibit A.
Filed 09/21/11 Page 4 of 12
Momenta is the assignee and owner of the '886 patent, which generally relates to
the identification of a structural signature of a low molecular weight heparin known as “enoxaparin sodium.” 14. 15. Sandoz is an exclusive licensee under the '886 patent. On September 7, 2010, the PTO lawfully issued the '466 patent, entitled
“Evaluating Mixtures of Low Molecular Weight Heparins By Chain Profiles Or Chain Mapping.” A true copy of the '466 patent is attached hereto as Exhibit B. 16. Momenta is the assignee and owner of the '466 patent, which relates to methods
of processing an enoxaparin preparation using chain sequencing methods to determine the presence of, or the presence and relative amount of, certain defined oligosaccharide structures. 17. Sandoz is an exclusive licensee under the '466 patent.
MOMENTA AND SANDOZ’S GENERIC ENOXAPARIN PRODUCT 18. On August 26, 2005, Momenta entered into a collaboration and licensing
agreement with Sandoz to develop a generic version of enoxaparin sodium. That collaboration led to the filing of ANDA No. 77-857, by which Sandoz sought approval from the U.S. Food and Drug Administration (“FDA”) to market enoxaparin sodium in the United States. 19. One of the key hurdles in developing a generic enoxaparin product was finding a
way to manufacture an enoxaparin that matched the unique structural profile of the branded enoxaparin drug product which is known by the trade name “Lovenox®.” To solve this problem, Momenta developed novel methods of processing an enoxaparin preparation that would match the structural profile of Lovenox®. 20. On July 23, 2010, the FDA approved the ANDA and allowed Sandoz to market
the first generic enoxaparin sodium product.
Filed 09/21/11 Page 5 of 12
The claims of the '886 patent are directed to, inter alia, methods “for analyzing an
enoxaparin sample for the presence or amount of a non-naturally occurring sugar associated with peak 9 of FIG. 1 [of the '886 patent] that results from a method of making enoxaparin that included β-eliminative cleavage with a benzyl ester and depolymerization.” The “non naturally occurring sugar associated with peak 9 of FIG. 1” is a sugar that includes a 1,6-anhydro ring structure. 22. The FDA requires a generic manufacturer to include in its manufacturing process
the analysis of each batch of its enoxaparin drug substance to confirm that its manufacturing process results in the production of oligosaccharides that include defined relative amounts of a non-naturally occurring sugar that includes a 1,6-anhydro ring structure. Accordingly, in order to sell a generic enoxaparin sodium product, generic manufacturers, like defendants Amphastar and IMS, must determine as part of their manufacturing processes, that sugars including 1,6anhydro ring structures are present in defined relative amounts in each batch of enoxaparin sodium that they produce. 23. The claims of the '466 patent are directed to, inter alia, methods of processing an
enoxaparin preparation by determining that one or more defined tetrasaccharide sequences is present or is present in a defined relative amount. 24. The FDA requires a generic manufacturer to include in its manufacturing process
the analysis of each batch of its enoxaparin drug substance to confirm that its generic enoxaparin has a distribution of oligosaccharide chain lengths equivalent to that of Lovenox® and that, within the subset of shorter chain oligosaccharides (including tetrasaccharides), its generic enoxaparin has a distribution of chain sequences that is the equivalent to that of Lovenox®. Accordingly, in order to sell a generic enoxaparin sodium product, generic manufacturers, like
Filed 09/21/11 Page 6 of 12
defendants Amphastar and IMS, must include, as part of their manufacturing processes, a method for determining that the tetrasaccharide chains in each batch of enoxaparin sodium have certain defined chain sequences in particular relative amounts. DEFENDANTS’ INFRINGING CONDUCT 25. On September 19, 2011, Watson announced in a press release that the FDA has
approved Amphastar’s ANDA for its generic enoxaparin product. A true copy of Watson Pharmaceuticals, Inc.’s September 19, 2011 Press Release entitled “Watson Pharmaceuticals Announces Approval of Amphastar’s Generic Lovenox®” is attached hereto as Exhibit C. 26. In its press release, Watson stated that “Amphastar is currently preparing for
launch and anticipates launching its Enoxaparin Sodium Injection product in the fourth quarter of 2011” and that Watson would be selling that product to retail pharmacies throughout the United States. See Exhibit C, Watson Press Release. 27. On information and belief, in order for the FDA to have approved Defendants’
manufacture of generic enoxaparin, defendants Amphastar and IMS will have included in their process for manufacturing batches of enoxaparin sodium for commercial sale: (a) a method for determining that a defined percentage of the oligosaccharide chains that make up enoxaparin include, at their reducing ends, a nonnaturally occurring sugar that includes a 1,6-anhydro ring structure, which method infringes the '886 patent; and a method for determining the presence, in the tetrasaccharide chains of its enoxaparin, of particular chain sequences or particular chain sequences in particular relative amounts, which method infringes the '466 patent.
On information and belief, in order to be prepared to launch their generic
enoxaparin product in the fourth quarter of 2011, Amphastar and IMS have manufactured, and/or are in the process of manufacturing, commercial quantities of generic enoxaparin sodium using the methods claimed in the '886 and '466 patents.
