HINTS TO INVENTORS. Inventors cannot be too careful to whom they show their inventions before obtaining protection. The patent, when obtained, may be rendered valueless if it be known to more than a verv limited circle before application is made. It is clear that a monopoly cannot be obtained as against the public, when the public are already in possession of the secret. Abov'iS all. if you desire a valid patent, do not sell the article before applying. The best thing, therefore, is to keep the invention secret until the application for patent is made. The law's protection begins the moment the papers are deposited at the Government Patent Office. Further advice may be obtained from Henry Hughes, Patent Agents, of Queen’s Chambers, Wellington, 432
