Technical databases patents

Chemical Abstracts. Chemical Abstracts (CA) [23] is a collection of chemical information, with nearly 16 million abstracts of journal articles, patents, and other documents. In addition, the CAOLD database contains over 3 million abstracts from 1907-1966. Sources for CA include more than 8000 journals, patents, technical reports, books, conference proceedings, and dissertations from around the world. CA patent database covers 29 national patent offices and two international bodies. About 16% of the CA database, approximately 2.5 million records, are from the patent literature. Chemical Abstracts is commercially available from the American Chemical Society in several formats. 

Chemical Abstracts Service/STN International The most comprehensive collection of national and international scientific and technical databases for the chemist. Maintained by the American Chemical Society. Covers literature, patents, CAS registries, and databases. Hundreds of scientific databases, nearly 20 million abstracts, search engines, including SciFinder. http-.jHnfo.cas.orghttp Istneasy.cas.org... 

Patent databases aie databases containing information gathered froin patent documents [46]. These describe both the technical aspects and the scope of a patent (patent protection) and arc specific to a country or a group of countries (Tabic 5-4). 

In order to meet the rising demand for information thousands of databases are available worldwide. Nearly all supply technical literature, economic information, patent references, and manufacturers addresses. Materials databases with numerical values are a relatively small part of these programs. Because the majority of these databases are from individual manufacturers of plastics, there is only limited comprehensive, neutral information on most materials in these software programs. 

Research articles of interest to biochemists may appear in many types of research journals. Research libraries do not have the funds necessary to subscribe to every journal, nor do scientists have the time to survey every current journal copy for articles of interest. Two publications that help scientists to keep up with published articles are Chemical Titles (published every 2 weeks by the American Chemical Society) and the weekly Current Contents available in hard copy and computer disks (published by the Institute of Science Information). The Life Science edition of Current Contents is the most useful for biochemists. The computer revolution has reached into the chemical and biochemical literature, and most college and university libraries now subscribe to computer bibliographic search services. One such service is STN International, the scientific and technical information network. This on-line system allows direct access to some of the world s largest scientific databases. The STN databases of most value to life scientists include BIOSIS Pre-views/RN (produced by Bio Sciences Information Service covers original research reports, reviews, and U.S. patents in biology and biomedicine), CA (produced by Chemical Abstracts service covers research reports in all areas of chemistry), MEDLINE, and MEDLARS (produced by the U.S. National Library of Medicine and Index Medicus, respectively cover all areas of biomedicine). These networks provide on-line service and their databases can be accessed from personal computers in the office, laboratory, or library. Some... 

CAPlus is the most current and most comprehensive chemistry bibliographic database available from the Chemical Abstracts Service (CAS) and covers from 1967 to date. CAplus coverage includes international journals, patents, patent families, technical reports, books, conference proceedings, and dissertations from all areas of chemistry, biochemistry, chemical engineering, and related sciences. 

RAPRA is a bibliographic database about rubber plastics, adhesives, and polymeric composites. It covers the worldwide scientific, technical, and trade literature, as well as patent documents pertinent to the rubber and plastics industries. It is produced by RAPRA Technology Ltd. and covers 1972 to date. 

CAplus. 1907-. Columbus, OH Chemical Abstracts Service. Daily. The bibliographic database from Chemical Abstracts. Provides worldwide references from over 9500 scientific journals and patent references from more than 50 patent-issuing authorities. Scope includes all areas of chemistry, biomedical sciences, engineering, and materials science, as well as other scientific disciplines. In addition to journals, conference proceedings, technical reports, books, dissertations, and meeting abstracts are fully indexed. Approximately 3000 new records are added daily. 

There are three types of patent databases of interest to the pharmaceutical industry those that index all patents from one or more countries and/or technical fields without adding significant value to the database records those that provide added value with abstracts or proprietary indexing applied by the database producer and databases that track information about new or approved drugs. 

Scientific Technical Network (STN) (http //stnweb.cas.org/) is probably the most useful and extensive structure-searchable resource for chemistry worldwide. More than 200 scientific databases are available via STN (this service is not free). Several related databases can be searched simultaneously ( cluster search ). Cluster presearch is free and very useful, as the number of relevant hits per database can be visualized in this way. The most important files on STN are the CA Registry, CA Plus, Beilstein and the INPADOC (patent data) file. 

The future system that will be offered to the chemical searching community represents the high level of investment and effort expended by both Derwent and INPI, in the creation of standards by which chemicals in patents are indexed. However, no database is effective if there is not a system by which it can be searched, and here is where full credit is due to the Telesystemes DARC team. Markush DARC is available today, a testament to the excellence and ingenuity of Jean-Claude Roussel, Technical Manager of the DARC team, his current staff, and the people that created DARC as a flexible piece of software in the past.
