PERIODICAL ARTICLES. Two Million References Easily Accessible. Some months ago there was noted in these columns the fact that the Edward C. Worden Laboratories at Milburn, N. J., had an elaborate scheme for listing chemical references and patents. In Chemical and Metallurgical Engineering for January 5, Mr. H. J. Payne describes this work in some detail. United States chemical and industrial patents issued since 1900 are indexed under approximately 9,800 headings, arranged alphabetically, comprising some 1,800,000 references, and this index is open for consultation without charge during office hours, by appointment. Arrangements can also be made to obtain typed lists bearing on specified subjects. In addition to patents, some sixty chemical journals, in many languages, are indexed and abstracted, special attention being paid in these abstracts to note mention of foreign patents. The Official Gazette of the United States Patent Office is checked each week and every patent, numbering about 300 per week, that might involve any chemistry whatever, is ordered. These are read by a competent chemist, who makes in duplicate on colored paper a double column of entries. In one column every process, operation or product is listed, in the other entries are made indicating every material employed in obtaining the results claimed. The two original colored paper analyses for each patent are next sent to a stenographic corps, where cross-indexes are made in the following fashion: Process, Operation or Product. A B Materials Employed. 1 C D 2 3 4 Sometimes as many as 3,500 cards have been made for a single patent. In conjunction with these files there is a library of 20,000 volumes. The Proposed French Patent Law-"Propriete Industrielle", Dec. 31, 1924. One of the main innovations of the proposed patent law which the French government presented to the Chamber of Deputies July 29th last, is the introduction in France of the "preliminary examination" with the peculiarity, which is not found in the law of any other country, that the examination is optional. Article 21 of the proposed law reads as follows: "Art. 21.-Anyone filing a patent application can, either at the time of filing or later, require that an examination without guarantee shall be made concerning the novelty and patentability of the invention. The amount of the special tax to be paid for this purpose and the conditions under which this examination shall be carried on will be determined by decree rendered on the report of the Minister of Commerce and Industries, according to the advice of the Technical Committee of Industrial Property. The results of the examination will be communicated to the inventor and, on his authorization, to third parties designated by him. Printed copies of the description thus examined and the original kept in the archives of the National Office of Industrial Property will be marked with the inscription "examined". In the study in question, the author draws a comparison between the advantages to inventors of the preliminary examination method of granting patents and those of the method of granting patents without preliminary examination. He mentions the well-known fact that this examination for novelty is by no means infallible and quotes the remarks made on the subject by Mr. Maurice Maunoury to the Chamber of Deputies in 1913; he says that One system of laws says to the inventor: "You claim to have made a patentable invention. I do not examine the value of your claim. I give you a deed, called a |
