(“Synopsys”) and against Defendant Sunlune Corporation (“Sunlune”) on Synopsys’ claim that Sunlune violated the anti-circumvention provision of the Digital Millennium Copyright Act (“DMCA”) more than 11,000 times. See Order Granting Pl.’s Mot. for Default Judgment (“Default Judgment Order”), ECF 45. The default judgment includes an award of $27,5000,000 in statutory damages under the DMCA and a permanent injunction prohibiting Sunlune from accessing or using Synopsys’ software without authorization. See Default Judgment and Permanent Injunction, ECF 46. Before the Court is Sunlune’s motion to vacate the default judgment, which has been fully briefed. See Def.’s Mot. to Vacate, ECF 55; Pl.’s Opp., ECF 56; Def.’s Reply, ECF 57. The Court heard oral argument on May 8, 2025. See Minute Entry, ECF 63. Sunlune’s motion to vacate the default judgment is DENIED for the reasons discussed Complaint Filed in January 2024 Synopsys filed this action on January 11, 2024, alleging the following facts: Synopsys, a software company headquartered in Sunnyvale, California, is a leading provider of electronic design automation (“EDA”) software used in the design, testing, and manufacture of microchips and electronic systems. See Compl. ¶ 8, ECF 1. Synopsys does not sell its EDA software, but instead issues licenses granting its customers limited rights to install the software and to access specific software programs subject to control by Synopsys’ License Key System. See id. ¶ 11. The License Key System can detect potential software piracy. See id. ¶ 14. Sunlune is a chip design company headquartered in Santa Clara, California. See Compl. ¶ 15. In 2023, Sunlune entered into a limited license to Synopsys’ Fusion Compiler, HSPICE, and PrimeLib software products. See id. ¶ 17. Sunlune used counterfeit license keys to access more copies of the licensed products than was authorized, and to access a product not covered by the license, IC Compiler II. See id. ¶¶ 18-19. Synopsys’ investigation identified more than 11,000 instances of Sunlune operating counterfeit keys to obtain unauthorized access to Synopsys’ EDA software. See id. ¶ 20. Based on these allegations, Synopsys filed the present lawsuit, asserting claims against Sunlune for violation of the DMCA and breach of contract. See Compl. ¶¶ 22-36. TRO Issued in January 2024 and Preliminary Injunction Issued in February 2024 On January 25, 2024, the Court granted Synopsys’ application for a temporary restraining order (“TRO”) prohibiting Sunlune from accessing, using, transferring, or copying any Synopsys software without authorization from Synopsys. See TRO, ECF 17. On February 21, 2024, the Court issued a preliminary injunction. See Prelim. Inj., ECF 27. Sunlune’s Pro Se Answer Stricken in April 2024 On March 11, 2024, Sunlune filed a pro se answer to the complaint signed by its Director and CEO, Fuquan Wang. See Answer, ECF 29. Synopsys moved to strike the answer on the basis that a corporation may not proceed pro se in federal court. See Pl.’s Mot. to Strike, ECF 31. granting the motion to strike the answer (“Order Striking Answer”) and advising Sunlune that it may appear in this action only through a licensed attorney. See Order Striking Answer, ECF 34. Specifically, the Court stated in the order that:
