Yes, as RichS said, but also consider Georges comment, at least in the US you cannot offer for sale or use this patented product.

You simply cannot manufacture, import, distribute or sell patented products in countries where the invention is patented. If the patent holder catches you doing any of these 4 actions, they can get a court order to arrest you and sue you for loss of profits. In some countries, the landlord can sue you to triple your income. Simply put, US patent laws do not extend beyond US borders, just like Canadian patent laws; they do not apply outside of Canada. Etc. I suggest you be careful if you plan to sell a patented product even in other countries. Or even sell an imitation product made in other countries.
