About Rob Cashman

Robert Z. Cashman is a registered Patent Attorney (USPTO Reg. No. 60,246), copyright infringement attorney, and the founder of Cashman Law Firm, PLLC. For more than two decades he has represented clients throughout the United States in copyright litigation, patent matters, software licensing disputes, and other Internet-related legal issues.

Since 2010, Rob has closely followed the development of BitTorrent copyright litigation, ISP subpoena practice, and federal copyright enforcement. Through representing clients in these cases, he recognized that many defendants, journalists, and even attorneys struggled to find reliable explanations of how these lawsuits actually work.

That experience led him to create TorrentLawyer™, an educational resource dedicated to explaining copyright litigation in plain English. Rather than offering generalized legal commentary, the articles draw upon years of practical experience helping clients understand ISP subpoenas, IP address evidence, anonymous John Doe lawsuits, motions to quash, settlement negotiations, and the procedural stages of federal copyright litigation.

Today, TorrentLawyer serves as a growing legal knowledge base containing hundreds of articles designed to help readers understand not only what happens during a copyright case, but why courts, Internet Service Providers, copyright holders, and defendants each play the roles they do throughout the litigation process.
