Differences Between Patents And Trade Secrets


Patents and trade secrets have a lot in common: they both refer to new, innovative ideas and designs which sometimes (but don't always) turn into commercial successes. The biggest difference between the two is that patent information enters the public domain while trade secret information does not, but there is more to it than just that.

Time Limit

Every patent will eventually expire, although the exact length of time it applies can vary. Right now, a US utility patent lasts for 20 years from the

application date so long as you keep up with the maintenance fees. After that point, everyone can use the patented invention and the patent holder has no right to stop them.

By contrast, a trade secret has no expiration date: it lasts for as long as the business can maintain the secret. You also don't have to go through the expensive patenting process, although a trade secret still can't infringe on a patent.

The biggest reason to have a patent instead of a trade secret is that it's easier to sue someone for infringing. Even if that person came up with the idea independently, the patent holder has the right to order other people and companies to cease and desist. Trade secrets have protections against theft and misuse, but if someone legitimately discovers the same invention or recipe on his or her own, the trade secret is sunk.

Patents and trade secrets cover the same types of intellectual property, but each is appropriate in different cases. For most inventions, a patent is the best choice, but a trade secret still has legal protections.
