`
`INTRODUCTION
`
`A petition for inter partes review (“IPR”) “may be considered only if . . . the
`
`petition identifies all real parties in interest.” 35 U.S.C. § 312(a)(2). “That statutory
`
`requirement, thus, defines a ‘threshold issue’ for substantive review of the merits of
`
`the challenges presented in the Petition.” Galderma S.A. v. Allergan Industrie, SAS,
`
`No. IPR2014-01422, 2015 WL 1022410, at *3 (P.T.A.B. Mar. 5, 2015). As
`
`explained in detail herein, The Regents of the University of Colorado (the
`
`“University”) is intimately intertwined with Petitioner New World Medical, Inc.’s
`
`(“Petitioner” or “NWM”) business related to the technology at issue in this case. The
`
`University also has a strong financial motivation to invalidate the patent at issue in
`
`this IPR and is a beneficiary of this IPR. For these reasons and more, the University
`
`should have been named as a real party in interest (“RPI”) in this proceeding.
`
`Petitioner, however, not only failed to include the University in its list of RPIs
`
`when it filed the Petition, it also has staunchly refused to amend its identification of
`
`RPIs after Patent Owner notified Petitioner of this failure. Exclusion of the
`
`University from Petitioner’s list of RPIs conceals the University’s meaningful
`
`interest in this proceeding and is a calculated, collective attempt to avoid critical
`
`implications of estoppel. By failing to name the University as an RPI, Petitioner is
`
`paving the way for the University to observe the outcome of this IPR and have a
`
`second bite at the apple, should this IPR not succeed in invalidating all of the
`
`
`
`2
`
`challenged claims. Petitioner’s indifference to the estoppel provisions that underpin
`
`the statutory requirement to name all RPIs should not be countenanced.
`
`For the reasons that follow, and because the Petition omits the University from
`
`its identification of RPIs, Petitioner does not meet its burden under § 312(a)(2), and
`
`the Board should deny institution or order that Petitioner amend its mandatory
`
`disclosures to name the University as an RPI. Worlds Inc. v. Bungie, Inc., 903 F.3d
`
`1237, 1242, 1244 (Fed. Cir. 2018) (“an IPR petitioner’s initial identification of the
`
`real parties in interest should be accepted unless and until disputed by a patent
`
`owner” and a patent owner need only “produce some evidence to support its
`
`argument that a particular third party should be named a real party in interest”).
`
`II.
`
`PROCEDURAL BACKGROUND
`
`On September 4, 2020, Petitioner filed this IPR, listing itself as the only RPI.
`
`Paper 1, p. ix. After an unfruitful meet-and-confer, Patent Owner emailed the Board
`
`on October 7, 2020, requesting a conference call to seek authorization to file a
`
`Motion for Additional Discovery related to whether the University is an RPI to this
`
`proceeding. Ex. 3001. A conference call was held on October 27, 2020. During the
`
`call, the parties explained that Petitioner licenses the right to make products that
`
`directly compete with those of Patent Owner from the University and, while
`
`Petitioner agreed to produce a redacted version of that license agreement, Patent
`
`Owner argued that was not sufficient to illustrate the relationship between Petitioner
`
`
`
`
`and the University. On October 27, 2020, in view of the parties’ impasse, the Board
`
`3
`
`granted Patent Owner leave to file the motion for additional discovery. Paper 6.
`
`On October 30, 2020, Patent Owner filed its motion and attached discovery
`
`requests targeted to learn about the extent of the entanglement between Petitioner
`
`and the University. Paper 7, Ex. 2009. Shortly thereafter, on November 4, 2020,
`
`Petitioner and the University jointly sued Patent Owner in district court and, the next
`
`day, on November 5, 2020, Patent Owner sent an email to the Board, submitting that
`
`the complaint in that case should be included in the Board’s consideration of Patent
`
`Owner’s pending motion. Ex. 2012; Ex. 2013.
`
`On November 6, 2020, Petitioner filed its opposition to Patent Owner’s
`
`motion for additional discovery and attached a redacted version of Petitioner’s
`
`license agreement with the University. Ex. 1022. Notably, the redactions conceal the
`
`financial terms and thus the scope and size of the University’s benefit in Petitioner’s
`
`invalidating Patent Owner’s patents. Compounding the issue is that Petitioner
`
`completely ignored the fact that, both this IPR and the recent district court litigation
`
`brought by the University and Petitioner against Patent Owner are part of the same
`
`litigation and commercial strategy to clear competitive hurdles and pave the way for
`
`Petitioner to sell more product, which results directly in financial gain to the
`
`University.
`
`
`
`
`
`4
`
`Nevertheless, on December 10, 2020, the Board denied Patent Owner’s
`
`motion for additional discovery. Paper 13. The Board’s decision, however, gave
`
`insufficient weight to the fact that the University’s role in its partnership with
`
`Petitioner is not confined to that of a mere patent licensee, which is shown by the
`
`recent district court litigation brought by the University and Petitioner together
`
`against Patent Owner and the terms of the license agreement between the University
`
`and Petitioner. As explained below, this new evidence underscores the hand-in-hand
`
`relationship that the University and the Petitioner have adverse to Patent Owner that
`
`speaks to the need for the University to be named as a RPI to attach the estoppel
`
`effect of this and four other related IPRs.
`
`III. THE EVIDENCE SUPPORTS THAT THE UNIVERSITY IS A REAL
`PARTY IN INTEREST
`
`The evidence addressed below supports that the University is an RPI to this
`
`proceeding at least because (1) the University has voluntarily joined Petitioner’s
`
`legal disputes with Patent Owner related to the technology at issue; (2) the
`
`University and Petitioner have a long-standing, symbiotic business relationship; and
`
`(3) the University has a strong financial motivation to invalidate the patent at issue.
`
`First, there is no question that the University views itself as intimately and
`
`directly implicated in Petitioner’s legal disputes with Patent Owner, as the
`
`University is a co-party with Petitioner in an infringement litigation involving the
`
`very technology at issue here. By way of background, Patent Owner MicroSurgical
`
`
`
`
`Technology, Inc. (“Patent Owner” or “MST”) acquired certain assets of its
`
`5
`
`predecessor, NeoMedix Corp. (“NeoMedix”), in 2019. The acquisition included the
`
`innovative technology to less-invasive ab interno operating principles to treat
`
`glaucoma, thereby reducing operative and postoperative trauma significantly. Patent
`
`Owner also acquired certain related technology and associated patents, including
`
`U.S. Patent No. 9,107,729 (the “’729 Patent” or the “patent at issue”).
`
`Patent Owner competes directly, and arguably solely, with Petitioner in the
`
`market for its pioneering surgical devices, which include Patent Owner’s goniotome,
`
`TrabEx, TrabEX+, and Trabectome® products. Petitioner’s first competing product,
`
`developed roughly ten years after the Trabectome®, is known as the Kahook Dual
`
`Blade® (“KDB”). On June 4, 2020, Patent Owner filed a complaint of patent
`
`infringement against Petitioner, asserting that Petitioner’s ophthalmic surgical
`
`device infringes the patent at issue. Ex. 2004. Petitioner reacted by (1) filing this IPR
`
`on September 4, 2020, and then filing four other related IPRs;1 and (2) filing a
`
`
`1 Petitioner has sought IPR of all five patents-in-suit in the Delaware action.
`
`Patent Owner also asserts that University is a RPI in the four other IPRs: Nos.
`
`2020-01711, 2021-00017 and 2021-00065 (involving Petitioner and Patent Owner),
`
`and No. 2021-00066 (involving Petitioner and Patent Owner The Regents of the
`
`University of California). The Board’s RPI ruling should apply equally to all IPRs.
`
`
`
`
`retaliatory infringement suit against Patent Owner in the Western District of
`
`6
`
`Washington (the “Washington Litigation”), asserting its own recently-obtained
`
`patent against Patent Owner’s competing TrabExTM and TrabEx+TM (Ex. 2012) on
`
`November 4, 2020.
`
`While refusing to name the University as an RPI here, Petitioner joined the
`
`University as co-plaintiff in the Washington Litigation. The fact that separate lead
`
`counsel for the University have entered an appearance in the Washington litigation
`
`underscores that the University has an independent interest in that case, distinct from
`
`that of a mere licensor. Indeed, the University is the sole co-beneficiary of
`
`Petitioner’s infringement lawsuit. Under the redacted license, discussed further
`
`below, it is clear that the University controlled the decision to sue Patent Owner,
`
`making it entirely reasonable to believe the University is doing so likewise in this
`
`proceeding. Ex. 1022, p, 8 § 10.2 (
`
`); id. § 10.4 (
`
`
`
`
`
`
`
`
`
`
`
`
`
`); id. § 10.3 (
`
`).
`
`
`
`
`
`7
`
`Regardless of the actual financial terms that have been redacted in Exhibit
`
`1022, the University’s monetary stake is clearly substantial. As discussed in further
`
`detail below, given Dr. Kahook’s principal role in designing, developing, and
`
`promoting the KDB as well as the University’s public admission that the KDB is
`
`one of its own best success stories, crediting Petitioner’s license of one of
`
`University’s “highest-impact patents from 2019” as instrumental in elevating
`
`University into a “Top 20” research university. See Ex. 2008 at 1-2. There can be
`
`little doubt that the University recognizes that the direct consequence of any action
`
`having the effect of clearing Patent Owner’s patents from the competitive landscape
`
`will inure to the financial benefit of the University.
`
`Thus, the University will benefit from any redress this tribunal may provide
`
`just as much as it will benefit from any redress the Washington Litigation may
`
`provide. This is the very essence of the RPI inquiry and compels that the University
`
`should be an RPI here. Applications in Internet Time, LLC v. RPX Corp., 897 F.3d
`
`1336, 1348-49 (Fed. Cir. 2018) (“AIT”) (holding that “the focus of the real-party-in-
`
`interest inquiry is on the patentability of the claims challenged in the IPR petition,
`
`bearing in mind who will benefit from having those claims canceled or invalidated”
`
`and that the determination of who is an RPI should consider “who, from a ‘practical
`
`and equitable’ standpoint, will benefit from the redress that the chosen tribunal might
`
`provide”).
`
`
`
`
`
`8
`
`Petitioner’s sole attempt to justify its failure to list the University as an RPI in
`
`this proceeding, while effectively doing the opposite in the Washington Litigation,
`
`is that “the patent asserted in [the Washington Litigation] is not at issue in this or
`
`any other IPR proceeding filed by [Petitioner].” Paper 9, p. 5. That misses the mark.
`
`The point is that the Parties’ technologies and ophthalmic surgical devices in all
`
`proceedings are not only similar but also directly competing with one another. All
`
`of the proceedings against Patent Owner in this forum and in the district court are
`
`aimed at bringing financial gain to Petitioner and the University alike. The
`
`University thus should be listed as an RPI here, just as it bound itself as a party in
`
`the Washington Litigation.
`
`Second, Petitioner and the University have publicly acknowledged their
`
`symbiotic partnership with respect to the technology at issue. Notably, Petitioner did
`
`not design or develop the KDB. Rather, Dr. Malik Kahook, after whom the KDB is
`
`named, not only allegedly came up with the idea for KDB device during his tenure
`
`as a professor at the University but also purports to have designed and developed the
`
`KDB device. Ex. 2007. Through Dr. Kahook, the University also promotes the KDB
`
`as “a cost effective way to treat glaucoma . . . with a short learning curve for
`
`surgeons.” Id., p. 2. Indeed, Dr. Kahook has released numerous videos promoting
`
`
`
`
`and instructing others to use the KDB.2 Petitioner, on the other hand, operates as the
`
`9
`
`commercialization partner.
`
`This relationship is unlike the usual University technology transfer
`
`relationship, where the University merely innovates and licenses its patents to a for-
`
`profit entity who then designs, develops, promotes, and commercializes the
`
`technology. Petitioner recognizes this distinction: “We are excited to partner with
`
`the University of Colorado and Dr. Kahook to collectively further this objective by
`
`empowering surgeons with state-of-the-art
`
`technology
`
`to enhance patient
`
`treatment.” Id. at 2. The University regards the KDB as one of its own best success
`
`stories, crediting Petitioner’s license of one of University’s “highest-impact patents
`
`from 2019” as instrumental in elevating University into a “Top 20” research
`
`university. Ex. 2008 at 1-2. Despite the difference between standing under the
`
`Federal Rules and the RPI guidelines here, the University should be a party to this
`
`IPR.
`
`The University’s interdependent alliance with Petitioner continues to this day.
`
`Recently, after MST introduced its TrabExTM and TrabEx+TM, NWM announced that
`
`it soon will launch a new Kahook product, the “KDB GlideTM,” in the U.S. The new
`
`
`2 See, e.g., https://www.youtube.com/watch?v=k0TyWYtnZi8&t=72s;
`
`https://www.youtube.com/watch?v=d5YgdWgRU44.
`
`
`
`
`KDG Glide is only vaguely described in the publicly-available press releases, but it
`
`10
`
`appears that Dr. Kahook, while continuing to be employed by the University,
`
`specifically designed the KDB GlideTM to compete against MST’s devices, including
`
`MST’s TrabExTM and TrabEx+TM. Indeed, NWM funded a study that was conducted
`
`by Dr. Kahook and another colleague who is also employed by the University. Ex.
`
`2014. This study squarely pits the KDB GlideTM against MST’s TrabExTM device
`
`and appears to be a joint marketing effort of the University and Petitioner to co-
`
`promote their competing product against that of Patent Owner.
`
`The University’s own patents, which are licensed to Petitioner, similarly
`
`compare the technology and devices developed by the University against that
`
`developed by Patent Owner’s predecessor. For example, the University’s U.S. Patent
`
`No. 10,327,947, for which Dr. Kahook is the sole named inventor, compares the
`
`KDB against the Trabectome® over 36 times. Ex. 2006. The University’s U.S. Patent
`
`No. 10,786,391, which Petitioner and the University are asserting against Patent
`
`Owner in the Washington Litigation, likewise includes drawings and disclosures that
`
`compare the KDB and Trabectome®. Ex. 2015.
`
`This evidence, taken together, shows that the University and Petitioner have
`
`a relationship deeper than the typical licensee/licensor relationship. Not only does
`
`the evidence directly establish the University’s beneficiary relationship in this IPR,
`
`
`
`
`it also reasonably demonstrates some opportunity for the University to control or
`
`11
`
`fund Petitioner’s actions.
`
`Third, the patents that purportedly cover the KDB and the KDB Glide are
`
`owned by the University and are exclusively licensed by Petitioner. Ex. 1022 at p.
`
`3.
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`
`12
`
`
`
`
`
`
`
`
`
`, thus provide the University with a strong financial motivation
`
`to invalidate the patent at issue in this IPR. In this two-supplier market, Patent
`
`Owner’s patents are a patent risk for the University as well as for Petitioner. Were
`
`Petitioner enjoined from selling its Kahook Dual Blade and KDB Glide on the
`
`market, the University would suffer financial and reputational harm.
`
`In sum, from the first announcement of the KDB to this day, Petitioner and
`
`the University have been acting as one operation with respect to the technology at
`
`issue here. The foregoing evidence thus supports that the University and Petitioner
`
`have a shared interest to support and grow Petitioner’s business, including by
`
`invalidating the patents of its foremost, if not only, competitor in this IPR. The
`
`extensive, ongoing collaboration between Petitioner and the University with respect
`
`to the technology at issue supports that the University is an RPI to this proceeding.
`
`Institution should therefore be denied or Petitioner should be ordered to amend its
`
`mandatory disclosures to name the University as an RPI. AIT, 897 F.3d at 1351
`
`(requiring “a flexible approach that takes into account both equitable and practical
`
`
`
`
`considerations, with an eye toward determining whether the non-party is a clear
`
`13
`
`beneficiary that has a preexisting, established relationship with the petitioner.”).
`
`IV. THE UNIVERSITY SHOULD BE SUBJECT TO THE STATUTORY
`ESTOPPEL PROVISIONS
`
`Proper RPI identification is necessary “to assure proper application of the
`
`statutory estoppel provisions” in order “to protect patent owners from harassment
`
`via successive petitions by the same or related parties” and “to prevent parties from
`
`having a ‘second bite at the apple.’” Trial Practice Guide at 48,759. The legislative
`
`history indicates that 35 U.S.C. § 315(b) was intended to ensure the inter partes
`
`review is not used as a “tool[] for harassment” by “repeated litigation and
`
`administrative attacks.” H.R. Rep. No. 112-98 at 48, as reprinted in 2011
`
`U.S.C.C.A.N. at 78. Allowing such attacks “would frustrate the purpose of the
`
`section as providing quick and cost effective alternatives to litigation.” Id.
`
`Further, the Federal Circuit and the Board have embraced that the legislative
`
`purpose for the statutory RPI requirement includes (1) to ensure that third parties
`
`sufficiently closely aligned with petitioners would be bound by IPR final decisions
`
`under 35 U.S.C. § 315(e) estoppel, and (2) to safeguard patent owners from having
`
`to defend against serial IPRs from related parties. AIT, 897 F.3d at 1350; see
`
`generally, RPX Corp. v. Applications in Internet Time, LLC, No. IPR2015-01750,
`
`Paper No. 128 (P.T.A.B. Oct. 2, 2020).
`
`
`
`
`
`14
`
`While it is true that there is no time bar issue to this proceeding regardless of
`
`whether the University is an RPI, this does not negate the need to properly name the
`
`University as an RPI so that it may be subject to the estoppel provisions. To that end,
`
`this case is not like SharkNinja Operating LLC v. iRobot Corporation, No. IPR2020-
`
`00734, Paper No. 11, pp. 18-19 (P.T.A.B. Oct. 6, 2020), where the Board determined
`
`it need not address whether an unnamed third party was an RPI because, even it if
`
`were, it would not create a time bar issue. In that case, as the Board noted, it also
`
`would not create an estoppel issue because the Petitioner in that case offered to
`
`update its mandatory notices to identify that third party as an RPI. Petitioner has not
`
`done so here.
`
`The estoppel concern is especially grave here, where University is not a
`
`defendant in the Delaware action, and where University and Petitioner maintain a
`
`common incentive to invalidate the ’729 Patent. Without the application of IPR
`
`estoppel, University remains armed with a “collective” second bite at the apple. In
`
`this regard, the absence of a time bar with respect to naming University as a RPI,
`
`upon which Petitioner’s counsel has focused, is too narrow a path of inquiry that
`
`ignores other important RPI considerations like estoppel.
`
`Although the Board has emphasized the absence of a time bar in deciding
`
`respective cases based on the particular facts of the case, the Board has not
`
`subordinated the estoppel considerations. There is a strong public policy toward a
`
`
`
`
`petitioner honestly disclosing the real parties in interest so that a patent owner would
`
`15
`
`not suffer repeated administrative attacks. Petitioner has failed to do so.
`
`V. CONCLUSION
`
`The evidence of record “reasonably brings into question the accuracy” of
`
`Petitioner’s identification of real-parties-in-interest. Worlds Inc., 903 F.3d at 1242.
`
`Moreover, in light of Petitioner tying the University to the Washington Litigation—
`
`but not to this IPR—as well as other public statements evidencing the business
`
`relationship between Petitioner and the University, Petitioner knew or should have
`
`known that the University is an RPI. Coupled with the University’s financial and
`
`business motivations to invalidate the patent at issue and strengthen Petitioner’s
`
`position in the market in which it directly competes with Patent Owner, the evidence
`
`shows much more than a mere possibility that the University’s omission from the
`
`list of RPIs was a deliberate attempt to avoid estoppel. Petitioner and the University
`
`were clearly on notice and aware of all of the facts that required the University to be
`
`named as an RPI, but Petitioner chose not to do so.
`
`Especially at this stage of the proceedings, there also would be no prejudice
`
`to Petitioner and the University, as they are free to pursue their invalidity theories
`
`regardless of whether the Petition is amended to add the University as an RPI. On
`
`the other hand, Patent Owner, in the absence of the University being named as an
`
`
`
`
`RPI, would be subject to follow-on petitions from the University and the legal fees
`
`16
`
`in defending against them.
`
`For the foregoing reasons, Patent Owner respectfully asks that the Board
`
`decline to institute inter partes review of the ’729 Patent or order that Petitioner
`
`amend its mandatory disclosures to name the University as an RPI.
`
