In that trade I myself, shortly before my retiring from commerce, paid £3,000 for a year’s right to use a new process, which proved unworkable, and had to pay a _solatium_ of £1,000 for leave to discontinue it. The agricultural interest should not remain indifferent. Mark what was told the Commission by Mr. Reeve, Registrar to the Privy Council. In Mr. Bovill’s Patent there was charged a royalty of 6d. a quarter on all the corn ground in Great Britain by millers who thought it desirable to adopt his plan. Obviously the royalty in that case had the effect of a protective duty leviable for individual benefit, and enabling foreigners to undersell in the British markets. And what title to this power had Mr. Bovill? He was not the inventor. Another case is exhibited in the following extract from a private letter with which I am favoured, from a highly respectable quarter:— “Patents have become so numerous and so various, that it is not safe to use any piece of machinery, or make any variation without first making a careful search to ascertain whether it is not protected by a Patent. The Patent-Law has also been the cause of much litigation, there being very few Patents of any real worth but have had to go through the ordeal of the Law Courts, and there can be little doubt that injustice has frequently been done both to patentees and to the public. A case of considerable hardship connected with our own trade occurred regarding the application of the exhaust to grinding purposes. It was clearly proved at the trial that the machine for which the patentee claimed protection had been in public use in Denmark, where it had been seen by a Glasgow miller, who erected a similar machine on his premises in Glasgow, but hastily threw it aside without putting it to a proper test prior to the date of the Patent, but it was held that no profitable use having been made of the machine by the Glasgow miller, the Patent was good and perfectly protected. In our opinion a Patent obtained in such circumstances should never be allowed to stand, and if some means could be devised for ascertaining the circumstances beforehand, it should never be granted. The trade suffered very considerably in consequence of this Patent being sustained, and the consequence was, that although the patentee was not the original inventor, he pocketed a very large sum of money.
