Firm celebrates 150 years of intellectual property law

This year marks the 150th anniversary of Reising Ethington PC—Michigan’s oldest intellectual property law firm. In 1865, when Col. Thomas S. Sprague opened his patent practice in Detroit, he could not have imagined that what he was establishing would someday grow to a firm representing inventive geniuses like Ransom E. Olds (Oldsmobile), David D. Buick, the Fisher brothers, Elijah J. McCoy (the “real McCoy”), and Michael J. Owens (Owens-Illinois); as well as global clients that include automotive manufacturers and suppliers, medical technology companies, aerospace companies, universities, hospitals, makers of manufacturing equipment, and consumer product companies.

Today, with offices near Detroit and Dallas (both just minutes away from U.S. Patent Office locations) Reising Ethington works with clients in a broad range of technologies including mechanical, electrical, chemical, materials, computer science, and software and business methods.  Its attorneys are casebook authors, adjunct professors, article writers, and speakers—leaders in intellectual property law.

According to Reising Ethington Shareholder Jim Stevens, “We are proud of our history and continue to operate the firm based on the core values that have served us well for a century-and-a-half: client service, expertise across all aspects of intellectual property law, and taking care of our attorneys and staff. Our clients’ technologies are advancing faster than ever and an important part of our job is to know their products, emerging technologies, and business objectives so that we can secure intellectual property rights for clients that consistently meet or exceed their expectations.”

Since its founding in 1865, the firm has specialized solely in the practice of intellectual property law, including the prosecution and litigation of patents, trademarks, and copyrights. Other areas of specialization include managing global patent portfolios, trade secrets, licensing, and unfair competition matters. Visit to learn more about the firm and its attorneys.
