What is a Patent?
A patent is granted by a government
agency and gives the inventor the right to exclude others from making,
using or selling the invention from the day the patent is granted to a
maximum of 20 years after the day on which a patent application was
filed. To find out more about patents refer to the Canadian Intellectual Property Office (CIPO) or the United States Patent and Trademark Office (USPTO) web sites.
