Really? You Are the Inventor of Post-it Notes? Really?

What was the movie in which the two girls return to their high school reunion and claim they are the inventors of the Post-it® Note? It seems that one Alan Amron filed a trademark infringement lawsuit against 3M, claiming that he is the true inventor of the Post-it note. The case was dismissed because Mr. Amron filed a similar lawsuit that was settled 20 years ago. And, he is not the inventor.

To set things right, U.S. Patent No. 5,194,299 for “Repositionable pressure-sensitive adhesive sheet material” is the patent behind the Post-it Note, and the inventor is long-time 3M scientist Arthur Fry. The Post-It trademark is U.S. Trademark Serial No. 3861083. Both the patent and trademark are assigned to 3M Company. And while the patent has expired, the trademark is still active.

Post-it is a registered trademark of 3M Company.
