Before me is Defendant Highridge Medical’s partial motion to dismiss Plaintiff Roger P. Jackson, M.D.’s second amended complaint. (D.I. 42). Highridge’s partial motion to dismiss seeks to dismiss Dr. Jackson’s infringement claims asserting U.S. Patent Numbers 9,662,143 (the patent”), 9,999,452 (the “’452 patent”), 10,064,660 (the *’660 patent”), 10,898,233 (the *°233 patent”), 11,045,229 (the “’229 patent”), and 11,134,993 (the “’993 patent”). (D.I. 42 at 1). I have reviewed the parties’ briefing (D.I. 43, 49, 55) and I heard oral argument on March 10, 2026. At the oral argument, I denied Highridge’s motion to dismiss the infringement claims related to the °452, °660, and *233 patents. For the reasons set forth below, Highridge’s motion to dismiss is granted for the infringement claims related to the °143, °229, and °993 patents. I. BACKGROUND In the second amended complaint, Dr. Jackson sued Highridge! for infringement of thirteen patents by two of Highridge’s products—the Vitality Spinal Fixation System and the Vital Spinal Fixation System. (D.I. 39). Highridge responded with the pending partial motion to dismiss. (D.I. 42). In its partial motion to dismiss, Highridge argues that Dr. Jackson is not the owner nor exclusive licensee of six of the thirteen asserted patents. (/d. at 1). Highridge argues that the rights to the °143, °452, 660, ’233, °229, and °993 patents were assigned to NuVasive, Inc. (“NuVasive’’) as part of the “Top Notch IP” identified in a 2014 agreement (the “2014 Agreement”) between Dr. Jackson and NuVasive. (/d.). Highridge argues that the 2014 Agreement should be read as an assignment that transferred all ownership rights, and therefore standing, to NuVasive. (/d. at 4).

' Dr. Jackson originally filed this suit against Defendant ZimVie, Inc. (D.I. 1 at 1). Defendant ZimVie was substituted with its wholly owned subsidiary Zimmer Biomet Spine, LLC. (D.I. 23). After Zimmer Biomet Spine changed its name to Highridge Medical, LLC, the parties stipulated to updating the case caption to reflect the new name. (D.I. 47).

According to the 2014 Agreement, the Top Notch IP covers “the horizontal tool attachment feature” claimed in U.S. Patent Numbers 8,377,067 (the “’067 patent”) and 8,162,948 (the □□□□ patent”), and U.S Patent Application Numbers 11/272,508 (the “’508 application”) (now U.S. Patent Number 9,050,148) and 13/815,054 (the “’054 application”) (now U.S. Patent Number 8,900,272). Ud. at 1-2). The patents that Highridge seeks to dismiss were issued after the 2014 Agreement. (/d. at 4). Highridge argues that the ’143, ’229, and ’993 patents descend from and claim priority to the ’054 application. (/d.).” Dr. Jackson responds by arguing that the 2014 Agreement should be interpreted as a license agreement, not as an assignment. (D.I. 49 at 9-12). To make this argument, Dr. Jackson references two prior cases that he brought against other defendants. (/d at 13-15) (citing Jackson v. NuVasive, Inc., case no. 1:21-cv-53 (D. Del.); Jackson v. SeaSpine Holdings Corp., case no. 1:20- cv-1784 (D. Del.)). Dr. Jackson argues that I properly interpreted the 2014 Agreement in the NuVasive case such that the agreement did not include all technologies covered in the listed patents, but rather only covered the specific technologies recited in the agreement. (/d. at 14). Dr. Jackson argues that this interpretation is proper based on Missouri contract law and principles of patent law that prevent the assignment of some but not all of a patent. (/d. at 14-16). In making this argument, Dr. Jackson argues that the 2014 Agreement was not self-executing and was

2 The °452, ’660, and ’233 patents do not claim priority from the patents specified as part of the Top Notch IP. Highridge argued that the 2014 Agreement is an assignment of the horizontal tool feature generally and the stated patents merely serve as examples of the horizontal tool feature. (D.I. 42 at 3). Highridge argued that ’452, °660, and ’233 patents all include the horizontal tool feature, and thus, are included in the 2014 Agreement as part of the Top Notch IP that was transferred to NuVasive. (/d.). As explained in my ruling during oral argument, Highridge’s motion to dismiss these patents requires factual determinations that cannot be made at this stage. Without these factual determinations in favor of Highridge, Dr. Jackson has met his pleading burden under Rules 12(b)(1) and 12(b)(6). Highridge made similar arguments that the ’143, ’229, and °993 patents contain identical figures to those contained in two of the patents identified in the 2014 Agreement. I do not address these arguments for similar reasons.

amended by a later executed Schedule 2.01, and thus, must be interpreted based on the later agreed terms. (/d. at 12-13). These later agreed terms, Dr. Jackson argues, limited the license to the specified patents and removed rights for the 054 application (the ’272 patent). (/d. at 10-11). Dr. Jackson argues that his previous NuVasive case confirmed he is the owner of the patents. (/d. at 17). Ifthe 2014 Agreement is determined to be an assignment of entire patent rights, Dr. Jackson argues that even if the Court agrees with Highridge’s interpretation of the 2014 Agreement, the Agreement would not apply to the °143, °229, and °993 patents. (/d. at 18-20). Il. LEGAL STANDARD Rule 12(b)(1) of the Federal Rules of Civil Procedure permits the dismissal of a claim for “lack of subject matter jurisdiction.” “Article III standing is a jurisdictional requirement, which is incurable if absent at the initiation of suit.” Intell. Tech. LLC v. Zebra Techs. Corp., 101 F.4th 807, 814 (Fed. Cir. 2024). To establish constitutional standing, a plaintiff must show that (1) he has suffered a concrete and particularized injury in fact that is actual or imminent; (2) the injury is fairly traceable to the challenged action of the defendant; and (3) it is likely that the injury will be redressed by a favorable decision. Lujan v. Defenders of Wildlife, 504 U.S. 555, 560 (1992). In patent cases, “the question for the injury-in-fact threshold is whether a party has an exclusionary right.” Intell. Tech., 101 F.4th at 814. “[W]hether a party possesses all substantial rights in a patent does not implicate . . . subject-matter jurisdiction.” Lone Star Silicon Innovations LLC y. Nanya Tech. Corp., 925 F.3d 1225, 1235-36 (Fed. Cir. 2019). A Rule 12(b)(1) motion may be treated as either a facial or factual challenge to the court’s subject matter jurisdiction. Constitution Party v. Aichele, 757 F.3d 347, 357-58 (3d Cir. 2014). “In reviewing a facial attack, ‘the court must only consider the allegations of the complaint and documents referenced therein and attached thereto, in the light most favorable to the plaintiff.’”

Id, at 358 (quoting In re Schering Plough Corp., 678 F.3d 235, 243 (3d Cir. 2012)).
