Canadian government patent fees depend on the size of the applicant entity, which may be either a “small entity” or “large entity”. Over the life of a patent, under the current schedule of government fees, a large entity will pay approximately $3000 more in government fees than a small entity.
The consequences for incorrectly claiming small entity status are potentially very severe: if fees are paid on a small entity basis when large entity fees should have been paid, the patent may be invalidated. In cases of doubt, this will likely become an issue in any infringement litigation brought by the patent owner thereby increasing the cost of the litigation far more than the potential savings.
if at the date of filing
Note: Unlike the US, this is a “one and done” test. It is entity size at the time of filing of the application that matters, and entity size does not change thereafter during the life of the application/patent.
To benefit from the lower fees accorded to small entities, the applicant must submit a Small Entity Declaration.
When the facts are clear, the applicant can choose to proceed on a small entity basis. If there is any doubt, we strongly recommend proceeding on a large entity basis.
If you qualify, we will prepare the Small Entity Declaration for you for signature. However, until we have received a signed Small Entity Declaration we will treat the applicant as a large entity. Thus, if you want to claim Small Entity Status when filing the application we must have received the signed Declaration before the filing.
