Requires that upon issuance of a patent, the Commissioner of Patents shall open the record of such patent for public inspection. Provides for the reexamination of patent validity upon the receipt of information contraverting the validity of such patent. States that if there is a prima facie showing that the invention claimed in such patent was in public use more than one year before the actual filing date, the matter shall be determined by the Board of Examiners-in-Chief in such proceedings as the Commissioner shall provide for by rule.
