ORDER DENYING DOE NO. 117 ’S MOTION TO QUASH AND TO PROCEED ANONYMOUSLY (DKT. NO. 18)

Before the Court is putative defendant, Doe No. 117’s motion to quash and to proceed

anonymously. Dkt. No. 18. Doe 117 objects to the plaintiff, Ansys, Inc.’s subpoena requesting identifying information. The plaintiff has not filed its response. For the reasons explained below, the Court the motion.

I. BACKGROUND On July 10, 2025, the plaintiff, Ansys, Inc., filed a complaint against Does 1 through 323, alleging copyright infringement and violations of the Digital Millenium Copyright Act. Dkt. No. 1. The plaintiff is a global leader in engineering simulation software that licenses its software programs to its customers. Id. ¶¶ 2 –4. The plaintiff’s software is protected by numerous U.S. copyright registrations. ¶¶ 38 – 53. The plaintiff alleged that the defendants obtained, installed on their computer systems, and used pirated Ansys software, committing willful copyright infringement and violations of the Digital Millenium Copyright Act. ¶¶ 5, 54 – 67. The defendants have been identified only by the Internet Protocol (“IP”) address through which the copyrighted works were allegedly downloaded. ¶¶ 23 34.

II. ANALYSIS At the time of filing its complaint, each defendant was identified only by an IP address. The Court granted the plaintiff’s motion for leave to serve third -party subpoenas before a Rule 26(f) Conference. Dkt. No. 5. In response, Doe 117 filed this sealed motion requesting that the Court quash the subpoena or allow Doe 117 to proceed anonymously (Dkt. No. 18). Doe 117 is a putative defendant — not a named party to this lawsuit.

A. Motion to Quash

Doe 117 ’s motion to quash is governed by Rule 45 of the Federal Rules of Civil Procedure, which requires a court to quash or modify a subpoena that “(i) fails to allow a reasonable time to comply; (ii) requires a person to comply beyond the geographic limits specified in Rule 45(c); (iii) requires disclosure of privileged or other protected matter, if no exception or waiver applies; or (iv) subjects a person to undue burden.” Fed. R. Civ. P. 45(d)(3); see Wiwa v. Royal Dutch Petroleum Co. , 392 F.3d 812, 817 18 (5th Cir. 2004). The movant bears the burden of showing that compliance with the subpoena would be unduly burdensome. Wiwa 392 F.3d at 818. In analyzing undue burden, the Court considers the following factors: “ (1) relevance of the information requested; (2) the need of the party for the documents; (3) the breadth of the document request; (4) the time period covered by the request; (5) the particularity with which the party describes the requested documents; and (6) the burden imposed.” Doe 117 argues that the Court should quash the subpoena because (1) Doe 117 has no involvement in the alleged conduct, (2) compliance with the subpoena imposes an undue burden on Doe 117, (3) the information sought is irrelevant, and (4) disclosure of Doe 117’s identity will lead to potential reputational harm. Dkt. No. 18 at 1. Doe 117 alternatively requests that the Court allow him or her to proceed anonymously as “John Doe, Subscriber Assigned IP Address 75.180.17.170.”

Doe 117 states, without any evidentiary support or authority, that the information requested is overly broad and irrelevant. Dkt. No. 18 at 1. This argument is unavailing. The subpoena seeks information that will allow the plaintiff to identify the putative defendants and evaluate the merits of the plaintiff’s case. Without this information, the plaintiff could not effectively pursue its claims. Doe 117 also asserts that he or she is innocent. The Court declines to quash the third-party subpoena based on Doe 117’s general denial of liability. Doe 117 contends that the subpoena is improper because he or she “had no involvement in the alleged conduct.” This argument is premature. If Doe 117 wants to contest liability, that argument should be raised once he or she is “brought properly into this case .” First Time Videos, LLC v. Does 1-500 , 276 F.R.D. 241, 250 (N.D. Ill. 2011) (denying motions to quash based on general denials of liability because such denials are not relevant to the validity of a subpoena). Because a general denial of liability is not a proper basis for quashing the plaintiff’s subpoena , the Court the motion to quash. See Strike 3 Holdings, LLC v. Doe , No. 4:22-CV-565-ALM, 2023 WL 5584044, *2 (Aug. 29, 2023) (citing Voltage Pictures, LLC v. Doe 1-5,000 , 818 F. Supp. 2d 28, 35 (D.D.C. 2011) and Strike 3 Holdings, LLC v. Doe , No. 18-CV-2648, 2019 WL 78987, at *2 (S.D.N.Y. Jan. 2, 2019)) (holding that the defendant’s general denial of liability held no weight in determining whether to quash a subpoena to an internet service provider).

B. Motion to Proceed Anonymously

Doe 117 requests that the Court allow him or her to proceed anonymously as “John Doe, Subscriber Assigned IP Address 75.180.17.170.” Dkt. No. 18 at 1. In analyzing whether a defendant may proceed anonymously, the Court must balance private and public interests. Sealed Appellant v. Sealed Appellee , No. 22-50707, 2024 WL 980494, at *3 (5th Cir. Mar. 7, 2024). Doe *4 117 generally asserts a potential for reputational harm. Such a generalized concern is insufficient to establish a right to proceed anonymously.

While courts allow defendants to proceed anonymously in cases that lend themselves to abusive settlement tactics, the Court does not find that this is such a case. See Ansys, Inc. v. Doe No. W-24-CV-00363-ADA, 2025 U.S. Dist. LEXIS 92043, *5 6 (W.D. Tex. Apr. 28, 2025) (comparing case involving infringement of copyrighted engineering software from cases alleging copyrighted adult videos (citations omitted)). This case involves the alleged copyright infringement of engineering simulation software. Doe 117 has not established that his or her privacy interests are any different than that of a defendant in any other case. The Court therefore DENIES the motion to proceed anonymously.

III. CONCLUSION For the reasons explained above, the putative defendant, Doe 117 ’s motion to quash the subpoena and to proceed anonymously (Dkt. No. 18) is DENIED .

SIGNED this 16th day of September, 2025.
