The number of patent applications published in 2013 or that entered national phase in Canada in 2013 was approximately the same as in 2012 at about 34,900 application. Smart & Biggar, Gowlings and BLG top the list of firms by volume of applications.

The number of applications filed without the services of an agent was down slightly to 677 applications, approximately 1.9% of applications.

Because patent applications are not typically published for 18 months after they are filed, the data used for this report is based on applications published in 2013. Many of these applications will have been filed 18 months earlier, perhaps as early as 2010. For national phase entry applications, these are typically published shortly after entry into Canada but may have an international filing date 30 or even 42 months earlier.

For comparison, see a similar list for 2012. I have previously prepared similar lists for trademark applications.
