Expiring Patents

Every day patents are expiring. Under the current Patent Act, patents last a maximum of 20 years from the date of filing. There are also ‘Old Act’ patents which expiry at the later of 20 years from the date of filing or 17 years from the date of issue.

The first ‘New Act’ patents expired on October 2, 2009. ‘Old Act’ patents are still expiring based on the issued date.

Most patent applications do not become patents, and many patents do not survive to the end of their terms. Every day, patents are becoming dead for failure to pay maintenance fees or other deficiencies.
