Every mental effort of inherent merit involving useful addition to the sum total of permanent human knowledge must have a definite aim and rest upon a fundamental basis. : The five volumes constituting this work and representing eleven years’ uninter- rupted labor of a small force is an attempt to cover in detail, by a line-upon-line index approximating seven hundred thousand entries, the chemical subject matter of all of the United States patents granted during the ten-year period January 1, 1915 to December 31, 1924 (U.S. Official Gazetté, volumes 210 to 329 inclusive) ; being the 398,377 patents between the issued numbers 1,123,212 and 1,521,589, of which 22,882 separate patents have been indexed herein together with the re-issues which have been published during this time. It is intended adequately to cover the whole field of chemical technology—organic, inorganic, biological, mineralogical, - pharmaceutical, photographic—thus comprehending from a patentability point of view the entire industrial chemical development in both the warlike and peaceful arts during this decennial period. In the index of patentees comprising the first portion of this volume, 14,526 names are recorded as sole or joint inventors. No attempt has been made to edit, amplify, curtail, expurgate, interlineate, trans- pose or correct any statement appearing in the patents indexed for obvious legal reasons, the subject matter being indexed as is and without comment. In patent adjudication it repeatedly has been held by the Courts that the construction and intent of a specification must be judged by the actual published statements solely, i. e., what the patentee said, and not what one of supposed superior knowledge might infer he intended to mean, and that the specification description must be stated with sufficient lucidity, exactitude and comprehensiveness so that “one skilled in the art to which the invention appertains ” by following the description alone, may be able to obtain the result specified and/or claimed. The involved phraseology, obvious circumlocution, and deficiency in chemical knowledge apparent in the description of some inventions render their indexing in an intelligent and understanding manner a matter somewhat of guesswork. In such instances the context has been indexed as printed, and then again indexed the way we deduced the invention should read. This accounts, in a measure, for the extreme detail with which this Index has been subdivided. The present litigation in respect to the aryl-substituted guanidines as rubber vulcanization accelerators is indicative of how exhaustive an index of this nature should be in order to become of maximum utility in anticipatory searches and searches involving alleged “lack of novelty” in a chemical process, or product, or both. The method of preparation of this Index has been as follows: The description of each patent as printed in the Official Gazette was critically examined, and if it appeared from the statements therein that the patent might contain subject matter of a chemical nature, the patent was purchased. From this original patent, the chemicals and chemical manipulations and mechanical devices were indexed with sufficient completeness and fullness to cover apparently all of the chemical subject matter from any angle which might be sought, each item or line being placed on a separate card. These cards were then reviewed against the original patent. Instead of typing the patent number at the close of each line, the cards resulting from the indexing of each patent were rubber stamped with the patent number by means of 6 PREFATORY STATEMENT a numbering machine, it having been found nearly impossible to write the same number of seven figures several times without transposition or other error in figures. These cards were then thrown strictly alphabetically, the duplicates under one heading combined on a single card, and the cards then re-typed introducing dashes, instead of phrases represented between adjacent commas. By the substitution of dashes instead of words and phrases, the bulk of this work has been reduced by about 1260 pages without contraction of statement. This formed the original manuscript which was then re-read against the individual cards. In preparing the original cards (3” x 8” in size), they were typed by being fed continuously into a typewriter at distances of about 4 inch apart against a carbon sheet and a letter-size sheet under- neath, so that following each patent indexed there appears one or more sheets with a carbon of each line written upon the individual cards—an excellent method of afterwards checking as to'the accuracy and completeness of indexing of the individual patent. The number of cards thus prepared from a single patent ranged from one or two in the relatively unimportant ones, to several thousand cards. For example, from U. 8. Patent 1,505,043, which is a dissertation upon the cellulose ether art, there were prepared 2756 individual cards, the carbon of the same comprising 108 typed letter-size sheets. The total cast to us of indexing this ten-cent patent exceeded one hundred sixty dollars. The patent and the carbon sheet (or sheets) of the cards pertaining thereto were then filed in a series of loose-leaf covers by numerically increasing numbers, the first number of the patent in the volume appearing on the back of the same. A library of 168 volumes was thus formed covering this period. It will be observed that a question mark has been placed in parenthesis in various places in the Index, indicating that while the patent has been indexed as published, we demur as to the completeness, clarity, accuracy or propriety of the statement so indexed. In the indexing of the patents of the decennial period 1905-1914 we are now engaged, as likewise upon the biennial period 1925-1926. It is hoped to keep the Index to date by the issuance of biennial volumes, and if the demand for a work of this character is commeasurable with the labor and expense involved, it is planned to continue working backward in series of volumes embracing the periods 1885-1904 and 1790-1884, thus eventually making the Index complete for the entire United States patent issuance. It appeals to us that such a series of volumes, if accurate and complete, would be a wonderful stimulus to chemical patent inventiveness and ingenuity in the United States; would minimize useless legislation based on faulty or inadequate information as to the extent of basicity of chemical patents already allowed ; indicate almost at a glance in an authoritative manner the precise state of the patent art for any given subject; and would substantially replace the laborious and not always satisfactory methods of search now available, at present based primarily upon systems of classification. We believe a patent index of this nature should be far superior in accuracy and completeness to the methods of patent search now available, provided the index is accurate, exhaustive and of maximum availability, for the reason that such a work indexes the subject matter from a line-upon-line scrutation of the specification and claims—the actual “guts” (a polite word in Shakespeare’s time) of the patent—and depends in no wise upon the heading or claims only, which are often intentionally (?) involved and misleading for a definite purpose in the mind of the patentee, the real essence of the invention being perhaps hidden in an unobtrusive paragraph, and phrased in an inconspicuous manner, presumably with a well-defined purpose in view. There are said to be “ tricks in all trades.” In this connection we classify the preparation and searching of chemical patents as a “ trade,” and for this and other reasons, the preparation of an adequate index of the entire gamut of chemical technology has involved much labor on our part in certain instances, in endeavoring to try to satisfy ourselves as to the breadth, scope, basicity and limitations of a given invention from perusal of the PREFATORY STATEMENT v specification context. In some instances we have obtained and read the File Wrapper from which the application eventuated into a patent, in order to clarify our own mind upon involved points. It would seem that some of the granted specifications must have been prepared by “ specialists,” if a specialist is one “who knows more and more about less and less.” Upon Leo Rutstein, our junior associate, who collaborated in the preparation of the Author’s former volumes, has devolved the responsibility of correlating the various systems of nomenclature and methods of procedure in indexing, in evolving a system applicable in maximum usefulness in an index of this character, which is composed of a non-homogeneous mixture of terms used in pure chemistry, chemical technology and chemical expressions of the trade and the works. The system of nomenclature used in Chemical Abstracts, Beilstein, “ Organische Chemie” and Richter and Stelzner, “ Lexicon der Kohlenstoff Verbindungen ” has been followed by combination.. In general, letters and phrases enclosed in parentheses are not to be considered in alphabetization. Letters and words in italics such as 0, m, p, d, l, leuco, racemic, etc., are not to be considered from an alphabetical standpoint. The numbering used in organic compounds is that followed by Chemical Abstracts, as far as it was possible to do so. The name used is of the largest parent compound it 1s possible to use for maximum clarity and to show the chemical structure. Thus 3-amino-hydroxy-benzene-sulfonic acid is hydroxy-metanilic acid. The name “ phenol-sulfonic acid ” is not used, save in a few exceptions. The only name used which indicates two functions is Naphthol-sulfonic acid, and in numbering these derivatives, the naphthol is always 1-naphthol or 2-naphthol, other groups being numbered to correspond. This is of paramount importance as several systems of numbering are used in the patents, and the same compound may appear under three or four separate headings. This heterogeneity has crept into the Patent Office archives mainly as the result of foreign patents being applied for in verbatim language to the foreign application, or having been translated into English in the country of their origin for filing here. All substituent groups are listed in strictly alphabetical order and not in the order in which they may occur in a homologous or isologous series, and include such poly- compounds as dimethyl and triethyl, which are listed as one group beginning with “d” and “t” respectively. For example, substituent groups herein are written in the following order: Amino-chlor-diamino-dibenzyl-ethyl-methyl-phenyl-ete. This is of importance as otherwise it would be impossible to tell which of the substituent groups came first in the name, and consequently the card or entry could be located only with difficulty. Amyl-butyl-ethyl-methyl-octane would be found as above, and not this combination beginning with (say) butyl, or ethyl, or methyl. The same is true when using the largest parent compound, as in the case of hydroxy-metanilic acid, cited above, the compound if written in one way would be found under “Amino-etc.,” whereas it should be found under “ Hydroxy-metanilic acid.” For this reason a large number (about 3800) “see” and “see also” cards have been used in order to clarify, simplify and knit together the Index into a compendium of maximum usefulness and speed of reference. The use of bis-, bi- and di- is that given in Chemical Abstracts. For instance, nearly all compounds which might approximately be called Di...... -methane, are listed herein as Methylene-bis...... A complete explanation of this matter is found in the Journal of the American Chemical Society 1917, vol. 39, page 1623. There are many articles and processes for which a large variety of words could be used as the index or leading word with equal propriety. We have endeavored to select as the “key” word or expression, that probably most familiar to a chemist or patent attorney, or the word or phrase most expressive of the thought in the least number of letters or words, in order to reduce the bulk of the Index to the minimum compatible with clearness. BUSY PREFATORY STATEMENT Most of the names are self-explanatory to those reasonably familiar with the particular subject involved. Names of minerals are based on Dana’s Mineralogy, those of pharmaceuticals and medicinal chemicals and therapeutic synthetics on the last edition of the U. S. Pharmacopeeia and the two Dispensatories. The name used in the heading of the entry is the preferred English name for the product. To research workers and authors, attention is directed to the wealth of data con- tained under the respective headings of the various topics. As a citation, under “ Benzaldehyde” are to be found on pages 727-729, a total of 258 citations of patented information under 229 separate headings. An inventor, through lack of chemical knowledge, or in an attempt to broaden the scope of his invention, or cover up the real essence of the specification, often indulges in generic rather than specific terms or expressions upon which two or more constructions may be placed, thus rendering the proper indexing of the patent difficult. If one is interested in (say) arsenous oxide (arsenic trioxide) the data may be found partially under “arsenic,” which is supposed to index only the elemental form, but undoubtedly has therein many references to the arsenic oxides, especially the trioxide. He should also consult “ arsenous oxide,” “ arsenic trioxide,” “arsenic oxide,” “arsenious acid,” “arsenic acid,’ and “arsenic pentoxide,” for the reason above stated. Then there are present in this Index a number of general headings such as “ arsenate,” “arsenite,” “article,” which would be superfluous if the patent were sufficiently specific from a chemical viewpoint, or if the inventor were not endeavoring to protect for himself a whole series of compounds, rather than a specific body in a general class. When examining the references under a specific heading, always at the end of the references refer to the heading for leads under “see ” and “see also” referencs in italics. In comprehending the entire U. 8. patent art covering the period of this Index for any given subject, if the Index is complete, it merely becomes necessary to order of the Commissioner of Patents, Washington, D. C., at ten cents each, the patents represented by the numbers appearing under any given subject. That is, this Index _ 1s supposed to be a complete search of the entire field of chemistry as shown by the granted patents and patent re-issues. The abbreviations used in this work are few and simple: “ mfr.” for manufacture, manufactured or manufacturing (whichever is most applicable) ; “ obtg.” for ob- tained by, obtaining; “contg.” for contained, containing; “ pro.” for production, producing. As an example of the use of dashes instead of words, attention is drawn to the seventeenth line from the top of page 250, which says: “—, —, —, mfr. of, process,” and which would read in full, “A process for the manufacture of alcohol by the . oxidation of air in the presence of a catalyst.” We have roughly computed the extent of the four succeeding volumes covering this decennial period Index of chemical patents by weighing the cards and headings comprising the same, and comparing them against the weight of the cards contained in this volume. The approximations are as follows: Vol. I. Preface and Index of Names, 138 pages; Subject Index, A-497; B-269. Total 904 pages. Vol. II. C-6%5; D-110; E-105. Total 890 pages. Vol. III. F-200; G-135; H-125; I-140; JK-35; L-145. Total 780 pages. Vol. IV. M-205; N-120; 0-90; P-355; QR-130. Total 910 pages. Vol. V. S-460; T-160; U-20; V-70; W-110; X-12; Y-10; Z-70. Total 912 pages. This gives an apparent approximation of 4396 pages for the five volumes. PREFATORY STATEMENT 9 It is a pleasure to acknowledge and to record the valuable assistance of the coadjutors who have co-operated in the arduous labor involved in some portions of a work of this character, who have contributed of their time, energy and specialized information so willingly, and without whose assistance the work could not have eventuated. If there is merit herein, the credit primarily to them belongs. Preston R. Smith, expert in the intricacies of organic chemistry; Dr. Carl Marx, Dr. O. W. Wilcox, and Messrs. De Witt Bell, Clarence H. Lehman, John W. Bruce and Clifford Evers are all entitled to special acknowledgment. Mr. George H. Stevens kindly looked over those portions of the index involving rubber and vulcanization acceler- ators, and allowed us to draw from his years of practical experience in the elucidation of this complicated subject. Mr. Frank Alva Worden threw the entire list of cards into the approximately 5780 separate indexing headings constituting the original card classification, a task involving nearly four years of uninterrupted labor and calling for a high degree of sustained perseverance. Tio Misses Jean N. Baker, Lydia Englander, Pauline 8. Newmark and Sophia R. Livingston, A. B. (in order of their seigniory), have devolved the responsibility of spelling and card classification, the retyping of the cards upon sheets with the replacement of words and phrases by the corresponding number of dashes, and the almost endless checking of the references against the original patent specification to ensure the minimum of inaccuracy. Grateful appreciation is acknowledged to the technical staff of the Chemical Cata- log Company, Inc., for valuable assistance during the progress of the planning and printing of the work, and to The Lord Baltimore Press, of Baltimore, Md., for the execution of what must be conceded to be an unusual and difficult piece of typog- raphy. This point becomes especially pertinent when it is remembered that the entire work, from issuance of first galley proof to the completion of. printing, occupied a period of less than nine weeks. The Author would esteem it a courtesy to have his attention directed to such errors as have inadvertently (or otherwise) crept in. Pending the issuance of succeeding volumes, correspondence respecting data not yet published will be welcomed from those interested in topics which happen to begin with letters other than “A” or “B” comprising this volume.
