HC Deb 09 November 1928 vol 222 cc373-4W

asked the President of the Board of Trade the time allowed in different countries, including our Dominions, in which a patent has to be worked in the country or the patent forfeited?


In the countries which are parties to the International Conventions for the Protection of Industrial Property the position is governed by Article 5 of that Convention, which forbidsinter alia the revocation of a patent on the ground of failure to work, before the expiration of three years from the date of the grant of the patent.
