Briefly described, the paper clip of the invention comprises a single resilient wire with its center bent into an unclosed diamond shaped ring. I would also attach the same documentation as you would have in the paper-clip provisional as an appendix.This page provides information on the types of patents and types of patent applications, and the examination process. Over 150 years ago, on April 23, 1867, Samuel B. Fay was awarded, in the United States, the first-ever patent on a paper clip. The Gem paper clip can scratch or tear paper, catches on others of its kind in a box and, if spread too wide, slips off the papers it is intended to hold.
