DUTCH STATUTES RELATING TO LETTERS PATENT. Difference be- Charges. THE patent laws of the Netherlands are exactly the same as those already given with regard to Belgium. The law of 25th January, 1817, and 17th August, 1827, are precisely the same for both countries, but with this remarkable difference in practice,— that the above laws are strictly adhered to, and taken in their plainest and most literal sense, by the Dutch Government. The charges are the same; for five years, 150 florins; for ten, 300; for fifteen, 600; but fifteen years is not frequently demanded for patents of importation; because, as the patent must expire with the foreign one of which it may be an importation, we should sometimes be paying for fifteen years while only enjoying twelve or thirteen. The government requires the petitioner to give a Written obli- written engagement to pay the dues for patents up within three gation to pay months of its date; but it is only in January of the second year dues required. that an imperative demand is made for the payment: so that from thirteen months to two years can always be obtained for the pay Prolongation seldom granted. Secure patent ment. Prolongations of all kinds are rarely granted, and with great difficulty. Care should be taken to secure your patent before it be pubbefore publica- lished in any work. tion. Patentees should be careful as to foreign patents. Tax for pat ents of improvement afterwards returned. A patentee cannot, after obtaining a patent in Holland, solicit one in another country, without endangering his Dutch patent. On demanding patents of additional improvements, it is necessary that the whole of the tax be paid just as with a new patent; but nearly the whole of it is afterwards returned, as the law does not warrant a diminution of the tax, but a reward for rendering the invention' more perfect is legal. An additional patent, however, is never granted until the dues on the first patent have been paid up. DUTCH WEST INDIAN STATUTES RELATING TO LETTERS PATENT.
