Northwind IP Law celebrates 35 years


35 years – Northwind IP Law, S.C.

The intellectual property firm now known as Northwind IP Law was founded in 1983 by Tom Wilhelm after his job at American Can was eliminated due to restructuring. By that time, the U.S. Patent Office had conferred on Tom the title of “patent agent,” which enabled him to open a business representing clients with their new inventions before the patent office. His former employer quickly became his first client.

Innovation is all about improving and changing technology for the better, and the firm itself has likewise seen many changes over the years. What began in a small office in Neenah is now a larger office in the heart of Appleton. What began with a single man has grown and fluctuated from many attorneys in good times to just a few attorneys in leaner times, the size currently numbering three patent attorneys and three support staff. What began as Wilhelm Patent Service later, after Tom was licensed as an attorney, became Wilhelm Law Service, and then Wilhelm Law, and finally Northwind IP Law.

The ownership of the firm also changed a few years ago when Tom sold the business to Stephen Jensen. Both are still at the firm, together with a third seasoned patent attorney, Tom Connelly. Jensen was responsible for changing the firm name to Northwind. The new name honors the firm’s location in the New North region of Wisconsin, while contrasting with more traditional firm names based on the last names of the founders or owners.

What hasn’t changed over the years is the firm’s commitment to providing excellent legal services in the area of intellectual property to clients in Northeast Wisconsin, and beyond. It is with tremendous gratitude to the multitude of clients who have trusted their intellectual property needs to us over these many years that we recognize this milestone in our firm’s existence.
