Canada is underestimated as a patent filing country for US applicants
Even with its relatively small population, Canada is the largest export market for the US, with about 200 billion dollars worth of exports each year. Exporting to Canada from the US is a well-known process, and an inventor or company wishing to do so will have no difficulty in finding a company that can handle all the required paperwork and logistics. Even if one does not wish to export to Canada, licensing or sale of a patent is always a possibility. I have many clients whose business model revolves around finding products that sell well in the US and which are likely to sell well in Canada, having these products manufactured in China, and selling them in Canada. I often get asked to confirm that one of these products is not protected by a patent in Canada. If there is no Canadian patent, my clients are able to profit from the US inventor’s ingenuity.
