Mr. JENCKES. The Gentfrom Pennsylvania has remarked the ComPatents have made but few reports in favor of the extension ofexpiredpatents. the casesbrought to their attention are necessarily exceptional, and this, as the committee has determined, is one of the most remarkable exceptions. This man invented a mode of manufacturing pipes for the introduction of water into towns and cities. He came into competition with the article already in the market and the public were unwilling to take hold of it unless it was uarantied to do good service for 20 years. the ordinary life of a patent is 14 years, and with an extension, 21 years, as in this case. The partitw who manufactured this pipe were required to give the purcha sers bonds that it would exist in good condition for 20 years. It seemed to us very muchlike a case where a.man invents something by which human life could be prolonged for 100years. His patent for 14 years was of very little service, because no one would purchase an article which required so many years to testit. We have reported in favor of this, that this inventor may go to the ComrPatents, and if he can make out the case that he made out at the termination of his original term of 14 years, that he had not received the compensation to which he was entitled, the Commissioner shall grant him a further extension of his time. One word now to the Gentfrom Massachusetts, [Mr. Dawns] The committee gave notice last Congress to all who wished to come in and contest the ( question, and show why this bill should not be avorably reported. But one person came. I presume the person that the gentleman represents, and upon inter, e A "flu rogation he admitted that he was an infringer on this man’s invention and that he knew he was an infringer, and that if the patent was extended he would have to pay license or royalty. That was the only ground on which he wished the committee to report against the extension. He said that he could contest the validity of the invention, but the references he gave us were so ridiculous that when reviewed in his presence he withdrew it as too frivolous a lea to stand.
