A patent gives the inventor the right to exclude others from making, using, or selling their invention for a certain time period. In exchange, the public (society) gets to learn and build upon the information in the patent to improve upon the invention or to create their own invention. The inventor has to provide enough details in their patent for a person with ordinary skill in the subject matter to make the invention. Challenge yourself to recreate the inventions described in these expired patents. Can you think of new uses for these inventions or of ways to improve upon them? (Requires Adobe Reader®)
