What's in a patent? Information. But can I find it?

highest volume chemicals have been evaluated and the sequences of unit processes identified. In addition, the chemical process files added to E C D I N will permit access to information on process conditions and the process, as well as the commonly reported feedstocks and products/byproducts. 19. What's in a patent? Information. But can I find it? Stuart M. Kaback (Research Information and Analysis Unit, Analytical and Information Division, Exxon Research and Engineering Company, Linden, N J, U.S.A.). J. Chem. Inf. Comput. Sci., 1984, No. 24, pp. 159-163. The information in chemical patents is used for many purposes, including but not limited to patentability, validity, and infringement studies, state of the art reviews, and the monitoring of competitive technology. For some of these purposes, only the information in patent claims is germane; for others, the examples are most important. Information is sometimes presented in a highly specific fashion, while at other times it is quite generic. Searches similarly are

sometimes aimed at specifics and other times at generics - - and often a specific search must contend with generic patents and vice versa. Overlying these problems are the difficulties of dealing with pictorial and numerical information and with the context in which information is presented. This paper examines these manifold problems, taking a close look at the kinds of information needed by the users of patent information.
20. Quantification, retrieval, and automatic identification of numeric data in organic chemistry journals. Joseph J. Pollock (Chemical Abstracts Service, Columbus, OH, U.S.A.). J. Chem. Inf. Comput. Sci., 1984, No. 24, pp. 139-147. The full text of American Chemical Society (ACS) primary journals may now be searched on-line. An important benefit of this capability is that it makes available a substantial amount of highly current numeric data, which can be used to help identify unknown compounds or retrieve data on known ones. Such searches are readily performed with high recall and precision. The amount of certain
types of numeric data is estimated, and an algorithm for identifying them in the journal text is discussed in detail.
21. An interpretation of chemical abstracts service indexing policies. Russell J. Rowlett, Jr. (Caropines, Myrtle beach, SC, U.S.A.). J. Chem. Inf Comput. Sci., 1984, No. 24, pp. 152-154. Throughout the early years of Chemical Abstracts Service, its document analysts selected index-access points that coincided with where a searcher would be most likely to look first. The growth of the literature, the broadening interests of chemists, and the increased complexity of the science demanded more systematization. Accordingly, six basic indexing philosophies have evolved from the beginning and are still followed today. They are (1) selection of subjects, not words, from original documents, (2) use of molecular formulas as central building blocks, (3) a high degree of specificity, (4) inverted names for organic molecules, (5) continuity, and (6) use of highly trained scientists-analysts for preparation of abstracts and index entries.
