Well, I did touch on it a little bit in my remarks: the fact that there's only a six-month window for correcting errors made by CIPO on registrations; the fact that applicants could be facing a class fee not only at the filing of an application but at renewal, for example, which occurs in the U.S. I will say that, at the moment, Canada has a filing fee of $250 for a trademark application and a registration fee of $200, regardless of how many goods or services are covered in an application. In the U.S., the per-class fee is $325 U.S., and they will charge a class fee if you're requesting an extension of time, etc., or filing a renewal application. It's an opportunity for costs to escalate quite a bit for business.
