In addition to the above, I find the following names as applicants for extensions, but the inventions covered by the patents sought to be extended is not mentioned: S.S. Turner, Arculous Wyckoff, De Witt C. Cummings, Moses Marshall, J.W. Fowler, and Holloway & Graham. Many of the applicants have apparently given up their cases for this session, but they may be only lying back to its close in hopes that in the final rush their "little bills" may slip through easily. Several bills tinkering at the patent laws are before Congress, and one of these (House Bill, No. 3,370) passed the House on the 30th ult. It has one section that may be made to work great harm to inventors, as it prevents infringers being sued for more than one year's damages previous to notice of infringement being given. By this bill, if it is allowed to become a law, a person will be able to build and use patented machines or processes for years in some out of the way place where the inventor cannot easily find him; and should he be discovered, he can only be sued for one year's damages. There are other sections in this bill which will bear ventilating. Another bill, introduced into the Senate by Mr. Paddock, provides that all appeals from the Board of Appeals shall be direct to the Supreme Court of the District of Columbia, instead of to the Commissioner as heretofore; and that the fees shall be the same as now paid to the latter official. Mr. Sampson has introduced into the House a bill changing section 4886 so that it shall read as follows: "SEC. 4886. Any person who has discovered any new or useful art, machine, manufacture or composition of matter, or any new or useful improvement thereof, not known or used by others in this country, and not patented or described in any printed publication in this or any foreign country, before his invention or discovery thereof, and not in public use or on sale for more than two years prior to his application, unless the same is proved to have been abandoned, may, upon payment of the fees required by law, and other due proceedings had, obtain a patent therefor: _Provided, That the manufacture or composition of drugs as a medicine shall not be patentable_." The change is the addition of the words in italics.
