Contributions: Inventors/Agriculture Patents -- NAL

The National Agriculture Library (NAL) of the USDA has compiled a list of agricultural patents granted to African-Americans and spanning the years 1834-1989. The four-page list itself can be found on the NAL/USDA site, and most of the patents referenced can be viewed at the Patent & Trademark Office database at http://www.uspto.gov/patft

These patent numbers are included in the NAL list so that they can easily be typed into a query box at the Patent & Trademark Office site. Full instructions are given on the NAL site.
