Interlibrary Loan and Purchase
UW-Stout students and staff members can request full copies of most U.S. patents, by patent number, through Interlibrary Loan at no cost. Other persons need to request copies through their local public library's interlibrary loan service. Individual patents, identified by patent number, can also be purchased from the Patent and Trademark Office or from Delphion. Some European and International patents are available in full text or for purchase from Delphion.
