Interesting Expired Trademarks and Patents

Great innovators have revolutionized the way society operates. Many brilliant minds have shared their inventions with the general public, instead of keeping them secret. Before the advent of patents and trademarks, these innovators remained susceptible to dishonest individuals who wished to steal their ideas. Patents grant intellectual property rights to an inventor who files one with a governing body, such as the United States Patent and Trademark Office. Patents exclude others from producing, using, or selling a design filed under the name of an inventor. The same concept applies for trademarks, which protect a word, name, symbol, or device used in the trade of goods and services. Trademarks distinguish these goods and services from those produced or offered by others and prevent others from using a similar mark; however, it does not restrict others from selling similar goods or services. Therefore, inventors should register their product and name with the appropriate governing bodies to protect their intellectual property rights.

Many patents and trademarks have literally changed the world for the better. Some inventors have succeeded enough to renew their intellectual property rights while others have failed to renew them. Once a patent or trademark expires, it becomes available to any interested parties who wish to use the design or mark in their entrepreneurial pursuits. Fortunately, this has led to improvements in previous designs. While many patents have changed the world, not every patent has proven itself valuable. In fact, there are weird and wacky designs that never make it into production. These are great for a good chuckle, but the patents that enable us to communicate from further distances, travel to foreign lands, and save lives from diseases deserve to receive attention to create a better future for us all.
