`
`
`
`COMPLAINT FOR PATENT
`INFRINGEMENT
`JURY TRIAL DEMANDED
`
`COMPLAINT
`
`Plaintiff Seagen Inc. (“Seagen”) complains and alleges as follows against Defendant
`
`Daiichi Sankyo Co., Ltd. (“DSC”).
`
`THE NATURE OF THE ACTION
`
`1.
`
`Seagen brings this action to protect its proprietary technology enabling the
`
`delivery of chemotherapeutic drugs directly to cancer cells. When Seagen began developing
`
`this technology, most chemotherapeutic drugs for cancer were not targeted, resulting in the
`
`delivery of treatments throughout the patient’s body and causing significant adverse side
`
`effects. Since then, Seagen’s pioneering innovations in the field of antibody-drug
`
`conjugates (ADCs), a type of therapy that directly targets chemotherapeutic drugs to cancer
`
`cells, have helped establish ADCs as an important pillar of cancer therapy. Seagen’s ADC
`
`technology is the result of decades of research and development effort by Seagen’s
`
`scientists and hundreds of millions of dollars of investment. Seagen’s transformative
`
`innovations have maintained Seagen’s leadership status even as other companies have
`
`entered the field, and Seagen’s innovations are embodied in more approved ADC therapies
`
`than those of any other company. DSC is a new entrant in the ADC field, and it infringes
`
`Seagen’s United States Patent No. 10,808,039 (the “’039 patent”). DSC has already booked

`

`
`
`Case 2:20-cv-00337-JRG Document 1 Filed 10/19/20 Page 2 of 13 PageID #: 2Case 1:20-cv-01524-LPS Document 21 Filed 01/26/21 Page 6 of 62 PageID #: 498
`
`tens of millions of dollars in sales of an infringing product, and appears intent upon
`
`expanding its infringing activities.
`
`2.
`
`ADCs are specialized cancer treatments that use a “linker” to attach (or
`
`“conjugate”) chemotherapeutic drugs to an antibody. The antibody in an ADC targets
`
`receptors on the surface of a cancer cell. The targeted cell then internalizes the ADC,
`
`releasing the ADC’s chemotherapeutic drug to kill the cancer cell. This technology is
`
`cutting edge. To date, only nine ADCs have been approved by the FDA.
`
`3.
`
`After its founding in 1998, Seagen pioneered a class of linkers with a
`
`cleavable amino acid unit for use in ADCs. This class is often referred to as “protease
`
`cleavable” because specialized enzymes within the cell called “proteases” cleave the bonds
`
`of the amino acid unit to release the drug. After more than ten years of fundamental
`
`research, Seagen received FDA approval for its first ADC employing this technology,
`
`ADCETRIS®, in 2011. Of the nine, now-approved ADCs, more use Seagen’s linker
`
`technologies than any other.
`
`4.
`
`All of the products in DSC’s ADC pipeline also use a protease cleavable
`
`linker that is covered by the claims of Seagen’s ’039 patent. The currently accused product
`
`is DSC’s DS-8201 ADC (now branded ENHERTU®), the first ADC in DSC’s pipeline to be
`
`FDA approved. On January 6, 2020, DSC announced DS-8201’s availability in the United
`
`States, noting that DSC would be solely responsible for manufacturing and supply. DSC
`
`causes DS-8201 to be imported into, offered for sale, sold, and used in the United States.
`
`DSC also ultimately books the United States sales of DS-8201, and these sales have totaled
`
`more than $70 million to date.
`
`5.
`
`DSC may seek FDA approval for its other pipeline products covered by the
`
`claims of the ’039 patent, including U3-1402, DS-1062, DS-7300, DS-6157, in the near

`
`should Seagen learn during the course of discovery that DSC has engaged in infringing
`
`activities as to these products.
`
`THE PARTIES
`
`6.
`
`Plaintiff Seagen is a biotechnology company formerly known as Seattle
`
`Genetics, Inc. Seagen develops and commercializes transformative therapies targeting
`
`cancer. Seagen is headquartered in Bothell, Washington, and incorporated under the laws of
`
`Delaware.
`
`7.
`
`Defendant DSC is a Japanese pharmaceutical corporation having its principal
`
`place of business at 3-5-1, Nihonbashi Honchō, Chūo-ku, Tokyo 103-8426, Japan.
`
`JURISDICTION AND VENUE
`
`8.
`
`This Court has subject matter jurisdiction under 28 U.S.C. 1331 and under 28
`
`U.S.C. § 1400(b).
`
`9.
`
`This Court has personal jurisdiction over DSC, as DSC conducts business and
`
`has committed acts of patent infringement, induced acts of patent infringement, and
`
`contributed to patent infringement in the United States, the State of Texas, and the Eastern
`
`District of Texas.
`
`10. DSC also has sufficient minimum contacts with the forum as a result of
`
`business it conducts within Texas and this district. DSC—directly or through subsidiaries
`
`or intermediaries including distributors, retailers, and others—offers for sale, and sells (as
`
`well distributes, advertises, and markets) products, including DS-8201, that infringe the
`
`’039 patent throughout Texas and this district. For example, DSC owns the U.S.
`
`registration for the ENHERTU® trademark for DS-8201. DSC acts in concert with others
`
`to purposefully and voluntarily place the infringing products in a distribution chain that

`Case 2:20-cv-00337-JRG Document 1 Filed 10/19/20 Page 4 of 13 PageID #: 4Case 1:20-cv-01524-LPS Document 21 Filed 01/26/21 Page 8 of 62 PageID #: 500
`
`foreseeably leads to the infringing products being offered for sale, sold, and used in Texas
`
`and this district as part of the ordinary stream of commerce. DSC has done so with the
`
`expectation that these infringing products have been, and will continue to be, purchased in
`
`Texas and this district and that such purchases be part of the ordinary stream of commerce.
`
`11.
`
`In addition, DSC’s subsidiaries and contractual business partners have
`
`operated as agents of DSC as parts of a business group in which executives of DSC make
`
`important operational decisions regarding the manufacture, importation, offer for sale, sale,
`
`and intended use of the infringing products, including DS-8201. Through these agents, DSC
`
`has conducted business and committed acts of infringement in the United States, Texas, and
`
`this district.
`
`12. Alternatively, to the extent that DSC is not subject to jurisdiction in any state
`
`court of general jurisdiction, this Court may exercise jurisdiction over DSC pursuant to
`
`Federal Rule of Civil Procedure 4(k)(2) because: (a) Seagen’s claims arise under federal
`
`law; and (b) DSC has sufficient contacts with the United States as a whole, including but
`
`not limited to manufacturing the infringing products and importing them into the United
`
`States and offering for sale, selling, and causing them to be sold in the United States, such
`
`that this Court’s exercise of jurisdiction over DSC satisfies due process.
`
`13. Venue is proper in this judicial district pursuant to 28 U.S.C. § 1400(b) and
`
`28 U.S.C. § 1391(c). DSC is a foreign corporation and may be sued in this district. Venue
`
`is further proper because DSC has committed acts of infringement in this district, and has
`
`purposely transacted business involving the infringing products in this district.
`
`PATENT-IN-SUIT – U.S. PATENT NO. 10,808,039
`
`14.
`
`Seagen is the sole owner of the ’039 patent and holds the sole right to enforce
`
`it. The ’039 patent claims priority to provisional applications filed on November 6, 2003,

`sf-4314096

`
`and March 26, August 4, and October 27, 2004. The inventors were all employees of
`
`Seagen at the time the priority applications were filed. Although the ’039 patent issued
`
`recently, DSC has been aware of one or more parent applications of the ’039 patent since at
`
`least 2008, and it has been aware of the specific application that issued as the ’039 patent
`
`since at least June of this year. DSC also has notice of the ’039 patent from the filing of this
`
`Complaint.
`
`15.
`
`The ’039 patent claims technologies associated with ADCs. At the time of
`
`the invention, most therapeutics administered to patients to treat cancer—such as
`
`chemotherapeutic drugs—were not targeted to cancer cells, resulting in systemic delivery of
`
`the therapeutics to cells and tissues of the body, including to healthy cells where they are
`
`unnecessary, often undesirable, and can cause considerable adverse side effects. In the late
`
`1990s, custom designed antibodies were developed as targeted agents for the treatment of
`
`cancer and certain autoimmune diseases, but they, too, had limitations. Combining these
`
`antibodies with chemotherapy drugs to deliver them in a targeted fashion was under
`
`investigation as a next-generation technology, and chemotherapeutic drugs that bind tubulin
`
`(an important protein for cell division), bind DNA, or inhibit topoisomerases (enzymes
`
`involved in DNA replication and transcription) were known to be leading candidates. But
`
`linkers that would release drugs only in the target cells proved elusive. The first ADC to
`
`reach the market had to be withdrawn due to off-target effects thought to be caused by an
`
`unstable linker that disassociated before the ADC reached the intended target.
`
`16.
`
`Seagen’s path-breaking work led to the development of protease-cleavable
`
`ADC linkers that were more stable (and thus more likely to deliver chemotherapeutic drugs
`
`to target cancer cells) than other linker types, and included research on a range of amino
`
`acid motifs that could be used in such linkers. Seagen also developed more predictable

`
`“cysteine” conjugation technology (technology which differs from the “lysine” conjugation
`
`technology favored by other companies), and technology for arriving at a desired
`
`drug-to-antibody ratio or “DAR” (a term that refers to the number of drug units linked to
`
`each antibody).
`
`DEFENDANT’S INFRINGEMENT
`
`17.
`
`The claims of the ’039 patent are directed to antibody-drug conjugates
`
`comprising a protease cleavable linker of four amino acids in length, wherein each amino
`
`acid is either glycine or phenylalanine. The ’039 patent is enforceable and valid, and DSC’s
`
`ADC products fall within the scope of the patent rights provided by the claims of the ’039
`
`patent.
`
`18.
`
`The claims of the ’039 patent cover ADCs with linkers having the formula –
`
`Aa—Ww—Yy–, wherein Aa is a stretcher unit that bonds to a sulfur atom of the amino acid
`
`cysteine in the antibody, Ww is an amino acid unit, and Yy is a spacer unit between the
`
`amino acid unit and the drug. Independent claim 1 provides that the stretcher unit Aa is the
`
`maleimide maleimidocaproyl, or “mc,” as shown in the diagram below.

`
`19.
`
`Claim 1 further provides that the amino acid unit Ww is a tetrapeptide of four
`
`amino acids in length, with each amino acid having the formula shown below in which R19
`
`is either hydrogen (i.e., the amino acid glycine, or “G”) or benzyl (i.e., the amino acid
`
`phenylalanine, or “F”):
`
`20.
`
`Claim 4, which includes the limitations of claims 1, 2, and 3, and the claims
`
`that depend from claim 4, are exemplary on the issue of infringement. DSC’s ADCs with
`
`this linker infringe Claim 4 because they comprise a maleimidocaproyl stretcher unit that
`
`bonds to a sulfur atom of the amino acid cysteine in the antibody, a tetrapeptide amino acid
`
`unit with the amino acid motif GGFG, and a self-immolative spacer unit. The
`
`drug-to-antibody ratio for these ADCs is about 3 to about 8. The chart below provides more
`
`detail regarding how DS-8201 infringes claim 4. U3-1402, DS-1062, DS-7300, DS-6157 all
`
`use the same linker as DS-8201.

`
`DS-8201
`DS-8201 is an antibody-drug conjugate. In
`DS-8201, the payload drug is conjugated to
`the antibody using a linker that has the
`claimed formula, including a stretcher unit
`mc, an amino acid unit Ww with the
`tetrapeptide motif GGFG, and an
`aminomethylene spacer unit Yy:

`
`
`In DS-8201, the antibody to which drugs
`are conjugated is trastuzumab.
`
`In DS-8201, the linker’s stretcher unit mc
`bonds to sulfur atoms on cysteine residues
`of the antibody.
`
`In DS-8201, the linker has an amino acid
`unit with the tetrapeptide motif GGFG.
`Glycine, or G, corresponds with the
`claimed amino acid formula wherein R19 is
`hydrogen. Phenylalanine, or F, corresponds
`with the claimed amino acid formula
`wherein R19 is benzyl.
`
`In DS-8201, the linker has an
`aminomethylene spacer unit.

`
`COUNT I: ENFORCEMENT OF U.S. PATENT NO. 10,808,039 AS TO ACTS OF
`
`INFRINGEMENT BY DEFENDANT
`
`21.
`
`Seagen hereby restates and re-alleges the allegations set forth in paragraphs 1
`
`through 20 above and incorporates them by reference.
`
`22. DSC has been and is now directly infringing, contributing to infringement,
`
`and inducing others to infringe the ’039 patent in this district and elsewhere in violation of
`
`35 U.S.C. § 271 at least by making, using, selling, offering to sell, and importing into the
`
`United States ADC products, including DS-8201, that meet the limitations of one or more
`
`claims of the ’039 patent.
`
`23. DSC has committed infringing acts without the permission, consent,
`
`authorization, or license of Seagen.
`
`24. DSC’s infringement is literal or under the doctrine of equivalents, or both.
`
`25. DSC, in addition to its own direct infringement, is currently actively inducing
`
`and encouraging infringement of the ’039 patent, and will continue to actively induce and
`
`encourage infringement of the ’039 patent. DSC has known of the ’039 patent at least since
`
`the time of Seagen’s transmittal of this Complaint to DSC, and had prior knowledge of the
`
`application from which it issued. DSC nevertheless actively encourages others to infringe
`
`the ’039 patent such as by promoting and encouraging the use of the infringing products,
`
`including DS-8201. DSC knowingly induces infringement by others, including importers,
`
`manufacturers, sellers, and users of the infringing products, including DS-8201. These facts
`
`give rise to a reasonable inference that DSC knowingly induces others, including importers,
`
`manufacturers, sellers, and users, to directly infringe the ’039 patent, and that DSC
`
`possesses a specific intent to cause such infringement. Importers, manufacturers, sellers,
`
`and users of the infringing products directly infringe the ’039 patent.

`
`26. DSC also contributes to infringement of the ’039 patent by manufacturing,
`
`offering to sell, or selling within the United States or importing into the United States
`
`components of the infringing products, including linkers such as those found in DS-8201,
`
`while having knowledge of the ’039 patent and knowledge that these components are
`
`especially made or especially adapted for use in products that infringe the ’039 patent.
`
`These components are not staple articles or commodities of commerce suitable for
`
`substantial noninfringing uses. Importers, manufacturers, sellers, and users of the infringing
`
`products including these components directly infringe the ’039 patent.
`
`27.
`
` DSC’s infringement has been willful. DSC had knowledge of the parent
`
`applications of the ’039 patent, including the application that issued as the ’039 patent and
`
`its published claims, before the filing of this Complaint. DSC has proceeded to make, use,
`
`offer for sale, sell, and import the infringing products, including DS-8201, despite knowing
`
`that the products would infringe the ’039 patent, and DSC have continued to make, use,
`
`offer for sale, sell, and import the infringing products, including DS-8201, since the filing of
`
`this Complaint. DSC was also generally aware of Seagen’s linker technology, inquired
`
`about it, and directly compared it to the linkers in DSC’s infringing products, including
`
`DS-8201, in articles, analyses, and presentations. For these and other reasons, DSC’s
`
`infringing acts have been egregious.
`
`28. As a direct and proximate result of DSC’s infringement of the ’039 patent,
`
`Seagen has suffered, and will continue to suffer damages, including lost profits.
`
`29.
`
`Seagen has also suffered damages from DSC’s infringement of Seagen’s
`
`provisional rights in the ’039 patent, as DSC was on notice of the published patent
`
`application for the ’039 patent and the issued claims are substantially identical to claims in
`
`the published application.

`
`PRAYER FOR RELIEF

`
`Judgment in Seagen’s favor against DSC that DSC infringed one or more valid
`
`and enforceable claims of the ’039 patent;
`
`b.
`
`c.
`
`A finding that DSC’s infringement was willful;
`
`An award of damages to Seagen in an amount to be proven at trial, including lost
`
`profits but in no event less than a reasonable royalty, as well as pre-judgment and post-judgment
`
`interest at the maximum rate permitted by law;
`
`d.
`
`An award of attorney fees and enhancement of any damages by virtue of the
`
`exceptional nature of this case under 35 U.S.C. § 285;
`
`e.
`
`f.
`
`A running royalty; and
`
`Such other relief as the Court deems just and proper.
`
`DEMAND FOR JURY TRIAL
`
`Seagen hereby demands trial by jury of all claims and issues so triable presented in this
`
`Complaint.
