Winneshiek County Patents
1861-1999

This is a listing of patents awarded to Winneshiek County residents between the years 1861 and 1999. The collection comes from the Davenport Public Library Patents & Inventors collection, and was originally created by the Iowa State University University Library. There have been over 350 patents awarded by the United States Patent and Trademark Office to Winneshiek County residents. This list ends at 1999. The complete list, current as of 2024, is available on the Davenport Public Library site.

Within each date range you'll find tables sorted by various criteria. The "Patent Drawing" column contains the original patent diagram. All listed patents will contain a patent diagram by project completion.

Additional information is available on the U.S. Patent Office basic search page. To search using their basic search page:

  • Copy the patent number from the Winneshiek County table.
  • On the U.S. Patent Office basic search page, paste the patent number into the Quick Lookup window.
  • You can also do a Basic Search using the search criteria in the dropdown selector window found below the Quick Lookup window.
  • Note that patent numbers must contain at least seven digits. If a patent number has fewer than seven digits, simply add leading zeros to the patent number.

Note

This is an ongoing project with pages uploaded and edited regularly as time permits. The complete set of records, including the original patent diagram images, is currently scheduled for completion mid-November 2024. Be sure to check back often.
