NUMBERAI INC., Case No. 25-cv-09636-PHK

Plaintiff, ORDER GRANTING NUMBERAI, INC.’S EX PARTE APPLICATION FOR v. LEAVE TO SERVE THIRD-PARTY SUBPOENAS Re: Dkt. 9 Defendant.

Now before the Court is Plaintiff NumberAI, Inc.’s (“NumberAI”) Ex Parte Application for Leave to Serve Third-Party Subpoenas Prior to a Rule 26(f) Conference. [Dkt. 9]. Because Defendant John Doe, subscriber assigned IP address number 199.230.10.107, (“Defendant Doe”) has not been identified or served with the Complaint yet, no opposition has been filed. Having reviewed Number AI’s application and all supporting documents, the Court GRANTS the ex parte application. NumberAI alleges that it has developed a “highly effective and specialized” AI agent for use by car dealerships to automate handling customer calls and inquiries, which Plaintiff classifies as a company trade secret. See Dkt. 1 at ¶¶ 2-7. NumberAI indicates it is a Delaware corporation with its headquarters in Oakland, CA. Id. at ¶ 25. Defendant Doe is accused of fraudulently obtaining a “secure, protected, and private” demonstration of Plaintiff’s artificial intelligence (“AI”) agent referred to as “Numa.” Id. at ¶ 1. NumberAI allegedly sells this AI agent to car dealerships throughout the country to “assist in time-consuming, administrative tasks.” Id. at ¶ 3. NumberAI allegedly offers a “secure, private, and live demonstration” of Numa to dealerships interested in testing or purchasing the Numa Service. Id. at ¶ 5. To access this demonstration, a dealership representative must provide NumberAI with verification that they are an employee of a car dealership. Id. NumberAI alleges that Defendant Doe contacted NumberAI using an email address ending in the domain name “@northsideautogreenville.com” that appeared associated with a real car dealership, “Northside Auto Greenville,” in South Carolina. Id. at ¶ 9. Defendant also allegedly provided NumberAI with a phone number, (864) 528-6080, which appeared to be associated with “Northside Auto Greenville.” Id. at ¶ 10. Defendant Doe, allegedly identifying himself to NumberAI as “Kevin Yan,” claimed to be based in South Carolina as an “Operations” employee at the dealership. Id. at ¶ 11. NumberAI alleges that, based on Defendant Doe’s claimed association with the car dealership, it provided Defendant Doe with a secure demonstration of Numa “on or around August 21, 2024,” and gave Defendant Doe “confidential contact information of other Numa Service customers to serve as references.” Id. at ¶¶ 13-15. When NumberAI subsequently attempted to contact Defendant Doe after providing access to Numa, NumberAI found that the email and phone number provided by Defendant Doe had been abandoned. Id. at ¶ 16. Upon contacting “Northside Auto Greenville” directly, the dealership allegedly informed NumberAI that no one by the name “Kevin Yan” had ever worked there and confirmed that the email and phone number that Defendant provided were not associated with that dealership. Id. at ¶ 17. NumberAI alleges that, upon information and belief, Defendant Doe gained unauthorized access to the dealership’s information technology systems to fabricate an email address domain. Id. at ¶ 18. NumberAI further alleges that, upon information and belief, Defendant Doe is an employee or agent of a NumberAI competitor and used the live demonstration to gather “competitive intelligence and trade secrets associated with the Numa Service.” Id. at ¶ 19. Defendant Doe was named in the Complaint solely in connection with a specific Internet Protocol (“IP”) address and the abandoned phone number. Id. at ¶ 1. “An IP address is a ‘unique United States v. Henderson, 906 F.3d 1109, 1111 n.1 (9th Cir. 2018). An IP address is not a physical address but instead is a unique identifier for every computer or server connected to the Internet. United States v. Forrester, 512 F.3d 500, 510 n.5 (9th Cir. 2008). As is well-known, consumers and households connect their home computers and other devices to the Internet by subscribing to a service through a vendor called an internet service provider (“ISP”), often a cable company, telecommunications company, or other similar service provider. Nat’l Cable & Telecommunications Ass’n v. Brand X Internet Servs., 545 U.S. 967, 974 (2005) (“The traditional means by which consumers in the United States access the network of interconnected computers that make up the Internet is through ‘dial-up’ connections provided over local telephone facilities. Using these connections, consumers access the Internet by making calls with computer modems through the telephone wires owned by local phone companies. Internet service providers (ISPs), in turn, link those calls to the Internet network, not only by providing a physical connection, but also by offering consumers the ability to translate raw Internet data into information they may both view on their personal computers and transmit to other computers connected to the Internet.”) (citations omitted). When a subscriber (or consumer) signs up for Internet service, the ISP assigns an IP address to that subscriber – essentially renting out the IP address to the consumer for the duration of their subscription service period. Columbia Ins. Co. v. seescandy.com, 185 F.R.D. 573, 575 (N.D. Cal. 1999) (“On the Internet, computers find each other by reference to Internet Protocol (IP) addresses, which are a series of numbers that are used to specify the address of a particular machine connected to the Internet. Domain names are alphanumeric strings that are associated with particular IP addresses. Thus to find the computer at 129.99.135.66, a user might type in uscourts.gov, and would never need to know the actual IP address.”). The consumer does not own the IP address – it is controlled by the ISP and designated to subscribers as they sign up for service. UMG Recordings, Inc. v. Doe, No. 08-cv-1193-SBA, 2008 WL 4104214, at *2 (N.D. Cal. Sept. 3, 2008) (“[W]hen an ISP is given a defendant’s IP address and the date and time of infringement, it quickly and easily can identify the name and address of a Doe defendant, i.e., the ISP’s subscriber, because that ISP sends monthly or regular bills to the subscriber and has the original service application documents from each subscriber, and because the ISP knows which of its IP addresses were assigned to which customers, it follows that an ISP’s internal records should typically include information sufficient to link a customer with the account corresponding to a particular IP address. Id. Here, NumberAI avers that it traced the IP address used by Defendant Doe’s device to a physical address in the Northern District of California first by identifying the IP address based on “software handling customer inquiries for the Numa demonstration.” [Dkt. 9-1 at ¶ 3; Dkt. 1 at ¶ 22]. NumberAI also avers that Plaintiff’s unidentified “online marketing partner that processed Defendant’s request for the Numa Service demo provided the IP address associated with Defendant which traced to a physical address either in San Francisco or Cupertino, CA, both of which are located in this District.” [Dkt. 1 at ¶ 23; Dkt. 9-2 at 7]. After identifying the IP address, NumberAI avers that internet research identified an ISP, Another Corporate ISP, LLC (allegedly doing business as “Monkey Brains”), as the ISP which provided ISP service to this IP address. [Dkt. 9-1 at ¶ 7]. That ISP is based in San Francisco, and the identified IP address is also allegedly located in San Francisco or Cupertino. [Dkt. 9-1 at ¶ 7; Dkt. 9-2]. Based on this investigation, NumberAI believes that Defendant Doe is the subscriber using assigned IP address 199.230.10.107. [Dkt
