1. The USPTO granted over 170,000 patents in one year and registered or renewed over 120,000 trademarks.
2. Abraham Lincoln is the only president to hold a patent. The patent number is 6,469 for “A Device for Buoying Vessels Over Shoals” that was granted on May 22, 1849. However, his invention was never manufactured perhaps because it added too much weight to the vessel that might cause it to get stuck on a sandbar. The model that Lincoln handed in with his patent application was carved with his own hands. The model is now on display at the Smithsonian Institution National Museum Of American History. 3.Silly Putty was invented by General Electric when they were trying to make a material like rubber during World War II.
