Can I file my Patent Application in Canada?
Since our office is close to the international border, and the automotive industries, Tier 1 suppliers, Tier 2 suppliers and
associated machine shops are located in and around both Detroit, Michigan
and Windsor, Ontario, people sometimes ask if their invention can be filed in both the United States and Canada. The short answer
is yes. The same basic patent application can be filed in both countries.
Filing patent applications in the Canadian Intellectual Property Office
Canadian Intellectual Property Office
is similar to filing patent applications in the United States
Patent and Trademark Office
with a few differences. The good news is that Canadian applications may be
filed with the same specification and drawings as the US application. The Canadian applications may be written and filed in
English, just like in the United States.
The Canadian application process is different in terms of fees. When Canadian applications are filed, just a filing fee
must be paid to establish the Canadian filing date. If the inventor(s) qualify as a small entity, a Small Entity
Declaration signed by each invention can be filed with the application to obtain a lower filing fee with the
Canadian Intellectual Property Office.
Once the Canadian application is filed, an examination request and an examination fee must be filed within five
years of the Canadian filing date before examination begins. An annual maintenance fee will also be payable
starting two years from the Canadian filing date. This is similar to a
in the U.S.,
except the U.S. maintenance fees are only due if a patent issues.
There is no Canadian equivalent to a U.S. provisional application.
If a Canadian application becomes abandoned for failure to pay a maintenance fee or for any other reason, there
is a one-year grace period available for reinstatement in Canada. However, a reinstated application loses
entitlement to an expedited examination.
A Canadian patent has the same enforecement lifetime as an American patent, generally twenty years from the date of filing.
A Canadian application filed after a corresponding US application may claim priority to that US application.
The Canadian Patent Office will subsequently treat the application as if it were filed on the same day as in the USPTO.
