Paul Nathan Tauger is Senior Counsel at AddyHart LLC, where he has practiced since 2021, focusing on intellectual property and commercial litigation. His patent litigation experience notably involves software and internet technologies, as demonstrated by his representation in cases concerning webpage creation, e-commerce tools, and hyperlinking systems. Beyond patents, his broader litigation practice encompasses trademark, trade dress, copyright, and trade secret disputes, as well as breach of contract and breach of fiduciary duty cases.

Tauger maintains a balanced practice, representing both plaintiffs and defendants in patent matters. His tracked cases show appearances for DiStefano Website Innovations, LLC as a plaintiff and defending Distefano Website Innovations, LLC against Unified Patents. The firm itself represents both patent owners and challengers across various technology sectors, including software, electronics, automotive, and pharmaceuticals.

Among his notable engagements, Mr. Tauger has been involved in DiStefano Website Innovations, LLC v. Bytedance Ltd et al., a five-patent infringement action concerning web infrastructure, where a related case in the Western District of Texas was voluntarily dismissed by the plaintiff, and another in the Eastern District of Texas was transferred to the Northern District of California and remains ongoing. He also has experience with Inter Partes Review (IPR) proceedings before the USPTO's Patent Trial and Appeal Board (PTAB), a listed practice area. An IPR (IPR2025-01061) filed by TikTok Inc. against DiStefano Website Innovations, LLC resulted in an institution decision to grant in December 2025.

Mr. Tauger earned his J.D. from Loyola Law School of Los Angeles in 1992 and has been admitted to the California State Bar since 1992.
