The question is, is there a cost benefit to filing a patent application in multiple countries with the same law firm and attorney?
Let's suppose that I file in the USA and Canada. I use the same law firm. Because the application is already prepared in English for the USA, there isn't much work left to be done to draft essentially the same application for Canada. The drawings would be the same.
And thus, would it be right to conclude that there is some cost benefit here? I.e., the total cost should be cheaper than the cost of filing in the USA alone + the cost of filing in Canada alone.
Am I right in this assessment?
