There are three main types of patents:
- Utility
- Design
- Plant
Each patent type covers a specific duration of time. For instance, the most common patent type, Utility Patents, last 20 years from the date of application. Learn more about the patent types via the USPTO's General Information Page.
According to the patent statute, any inventor who “invents or discovers any new and useful process, machine, manufacture, or composition of matter, or any new and useful improvement thereof, may obtain a patent". The invention or discovery, in addition to being new and useful, must also be non-obvious. Learn more in the video below:
