Legal Notice to all former and current clients of Northwind IP Law, S.C., f/k/a Wilhelm Law, S.C., f/k/a Wilhelm Law Service, f/k/a Wilhelm Patent Service, Appleton, Wisconsin.

Northwind IP Law discontinued its law practice on Tuesday, Sept. 29, 2020. The owner, Stephen C. Jensen, now practices intellectual property law from the firm of Davis & Kuelthau, S.C.

Northwind and its attorneys, including Stephen C. Jensen, Thomas J. Connelly, Thomas D. Wilhelm, and others, served a multitude of clients and created thousands of legal files for those clients over its many years of existence. The legal files may include paper files including physical documents or things, electronic files including electronic documents, or both. Most files relate to patent matters, trademark matters, copyright matters, or other intellectual property matters.

We have expended considerable time and energy contacting clients so that their legal files can be transferred to counsel of their choice, or returned to them, or securely destroyed according to their wishes, and hundreds or thousands of such files have already been successfully processed. But thousands more still exist, and our resources are finite. We cannot contact all of these clients, or determine if they still exist or if they have successors, beneficiaries, heirs, etc.

This announcement serves as legal notice to all affected clients and persons that:

  • Northwind will soon need to destroy or otherwise dispose of all remaining legal files in Northwind’s possession, to the extent permitted by law;
  • if you believe you may have one or more legal files at Northwind, and if you do not want such files to be destroyed, you will need to contact us immediately; and
  • the person to contact on behalf of Northwind is attorney Stephen C. Jensen, who can be reached at or

On behalf of Northwind —  Stephen C. Jensen, 15 Feb. 2021
