Protection of a patent is restricted to the country chosen by its holder. When there is an interest in the production or marketing of the patent technology in other countries, it is necessary to deposit translated copies of this application and each country will be sovereign to grant or not the patent. Once the countries of interest for international filing have been chosen, the holder may choose two ways: 1. Paris Convention  for the Protection of Industrial Property (Paris Convention) and 2. PCT (Patent Cooperation Treaty): The decision of the countries where the holder wishes to protect a particular technology is strategic through cost and benefit assessment. The following video summarizes these international filing possibilities. # i9pi
