Patents are government grants that give inventors exclusive rights to their inventions.
Patents are vital resources for businesses, researchers, inventors, academics, and others who need to keep abreast of developments in their fields.
Patents are also an important means of sharing know-how, because each patent document describes a new aspect of a technology in clear and specific terms and is available for anyone to consult.
Searching for patents on specific devices, processes, or inventions can be complex. If you are looking for a specific patent you can search by patent number or inventor’s name. However, if you are exploring what patents exist in certain areas you can search by keyword or browse the classification indexes:
