The Index is arranged in numerical order by class numbers, which appear as bold-face entries centered in the columns, and thereunder, in similar order, by subclasses which appear in the numerals in the left hand half of the columns. There are 66,149 patent and reissue patent numbers listed in the Index. A similar fisting appears for design patents, plant patents and defensive pubhcations which are separately shown under then respective classifications. In order to find patent numbers in the Index pertaining to a particular subject, the user must first know the class and subclass in which the Patent Office assigns inventions relating to that subject. In some instances a number of classes and sub- classes may be pertinent. The process of finding this information requires the co- ordinated use of several other Patent Office publications usually found in collections which contain the Index of Patents. Each of them is considered below. Manual of Classification: This publication is the source of the needed informa- tion as it contains the entire classification schedule showing the number and de- scriptive title of every class and subclass. It is, also, the key aid in the finding system as it provides a number of features aimed at assisting the user to identify his search problem and to use its content in locating the specific classification represent- ing the subject matter of concern to him. These features include (1) listings of the class titles in alphabetical order; (2) description of the plan of the Manual; (3) dis- cussion of the basis of classification, the scope of the classes, and the schematic arrangement of subclasses; (4) instructions on reading subclass titles and definitions; and, (5) suggestions on procedure for finding pertinent classification. Index to Classification: This publication contains about 300 pages of subject matter headings showing for each heading the class and subclass to which it per- tains. They are arranged in alphabetical order in main heading and subheading categories, the latter being indented under the main headings and sometimes further subdivided. The headings include key words and significant phrases taken from the class and subclass titles, but they are neither limited to this source nor include all of them. Many technical as well as common terms of reference to objects, arts, processes, compositions of matter, etc., not found in the classification schedule are included in the index headings so as to offer a practical and convenient aid to finding patented subject matter. Classification Definitions : This is a series of numbered publications which supple- ments the Manual of Classification by giving detailed definitions and illustration of the kind of subject matter that can be found in each class and subclass, describing the lines of distinction among them, and containing references to other classes and subclasses having related subject matter. There is a separate Definition for each major classification, which is identified in the heading to each class in the Manual. Use of Reference Publications As a first step, the searcher should look in the Index to Classification for the term which to him best represents the subject matter of interest. If a match is not 3 INDEX OF PATENTS, 1972 found, he should look for terms of approximately the same meaning, for terms of either broader or narrower scope, or for terms which represent a different approach to the subject (e.g., the essential function or the effect of use or appUcation of the art or object of concern) . This requires that the user interact with the content of the Index, exercising judgment and imagination to consider alternatives or to find in the hsted items some aspect of pertinency to his subject. On finding the identifying numbers of possibly pertinent classes and subclasses in the Index, the user should refer to the Manual of Classification and ascertain from among the existing choices, the precise classification identity of his subject interest. Having thus determined the appropriate class and subclass, the searcher is ready to turn to the "Classification of Patents" hstings to look for the correspond- ing numbers in its columns. The patent numbers found listed under the relevant classification provide the information needed to gain access to the patents themselves or to the extracts from them which are printed in the Official Gazette. In the latter connection, the user will find on the last page of this section a table entitled "List of Patent, Design, Plant Patent, Reissue and Defensive Publication Nimibers Appearing in the Official Gazette for 1972" which will guide him to the issue of the Ofiicial Gazette containing any specific patent number. He will find listed elsewhere in this section the 18 hbraries which receive all U.S. patents and maintain them for public use in numerical order and the more than 400 depository libraries which receive the Official Gazette. When the class and subclass which the searcher has determined to represent his interest does not appear in the "Classification of Patents" listing, he may assume that no patents were issued in that classification during the year. The possibiUty of this being the case is indicated by the fact that patents issued in less than one-third of the total number of subclasses in the classification. If, after following the above-described procedure in using the Index to Classifi- cation, the searcher fails to find a pertinent classification, he should turn to the hst- ings which appear at the front of the Manual of Classification. He should consider, particularly, the listing of groups of related subjects and the listing of classes arranged in alphabetical order which, in different ways, lay the entire framework of the classi- fication in broad focus before him. He should scan the titles which appear on these sheets and note those which would appear to contain the subject matter sought. Whichever of these approaches is taken, the searcher is guided to the classifica- tion schedules. He should inspect them carefully, proceeding from one major co- ordinate subclass to another until finding one which seems most nearly pertinent. The minor subclasses therein should then be scanned to find the title which indicates inclusion of the subject matter in question. Where doubt exists as to choice among several subclasses, the user should consult the Classification Definition contain- ing the definitions of the class under study.

a patent issued on July 13, 1836 under the Patent Act adopted July 4, 1836. Up to this time, a total of 9,957 patents had been issued. 2 The number of patents issued during a year may be fewer than the number derived by subtracting the number of the first patent issued in one year from the number of the first patent issued in the next year. Some numbers in the series may not be used. This results when an apphcation scheduled to be patented and to which a patent number is assigned is withdrawn for some reason at a time when it is too late to reassign that number. ^ Not separately numbered until 1838. * A new numbering system for Defensive Publications was adopted in December 1969. A conversion table reflecting this change appears in the Official Gazette of December 16, 1969, vol. 869, pages 687 and 688. 453 PATENT NUMBERS FOR WHICH NO PATENTS EXIST 1972 3,639,205 3,669,091
