A new initiative introduced by Derwent during 1995 is the Patents Citation Index, an on-line database of patent citations that includes both examiners citations and patentees citations to prior art from patent specifications. When given a known invention of interest, as represented by a patent family, the database can identify any patent against which it has been cited, as well as eadier patents cited by any member of that family.

EPIDOS ties together members of extended convention patent families, and in some instances identifies inteUectual families as weU. Legal status subsequent to pubHcation is also coUected for 16 authorities. 

EPIDOS issues printed and microfiche compilations of its data in addition, its database can be searched on its own computer or on several on-line host systems. In general, EPIDOS provides the most complete patent family information of any service, although Derwent tends to include more information on inteUectual (nonconvention) famUies, whereas the Erench Patent Office s EDOC file on the Questel system includes information on... 

EDOC, available on the Questel host from INPI, is unique among non-Japanese language databases in including information on C-stage Japanese patents, ie, those that have successfiiUy weathered the pregrant opposition period and been sealed as patents under pre-1966 patent law. It also contains some information on patent family relationships from the period long before the advent of patent family databases. 

An often forgotten source for some patent family information is the CLAIMS database. Although its direct coverage is limited to U.S. patents, it includes limited patent family information up to 1979, for Belgium, Prance, Germany, the Netherlands, and the United Kingdom. Some of this information from the pre-1970 era is found in no other on-line database. An earHer discussion of patent family databases has recentiy been updated (18). 

EDOG. EDOC, available on just the Questel system, provides in most instances less complete patent family information than either WPI or INPADOC, but it is unique in including Japanese C-level documents and also some AustraUan data not available in the other two databases. It is possible on occasion to find family information from before 1970 in this database, though such data are not provided systematically. The abiUty to search by the EPO-modified version of IPC is unique. Its value is tempered by the fact that output does not even include tides, much less abstracts of patents. That output can, however, be transferred by cross-file search protocols to more detailed files, such as WPI. 

Derwent International Patent Family File and U.S. Patents Full Text. Derwent International Patent Family File (DIPF) [75] provides access to 20 million patents issued by 40 patent-issuing authorities, covering more than 10 million inventions as far back as 1963. The DIPF is linked to U.S. Patents Full-Text (US-PAT) [75]. US-PAT contains the full text of more than 2 million patents issued by the U.S. Patent and Trademark Office since 1976. DIPF and US-PAT are available on the commercial online service Westlaw.

For comparison purposes and as a quick reference guide, Table 1 collects all the inventions in chronological order. Not all the patents are shown in Table 1, since in most cases global coverage was attempted, instead only the representative patents of each patent family are included.

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. 

A patent number index with information about the patent applicants, inventors, priorities and patent-families, an inventor index, a company index, and a subject index can be found at the end of the book. 

It is not unusual that a patent application has been filed in several countries referring to a common first filing i.e. priority. These applications are said to belong to the same patent-family. In this book English-speaking documents of the patent-families have been selected provided it has been possible. The patent numbers or patent application numbers of other documents belonging to the same patent-family as a cited document may be found in the patent number index at the end of the book. 

Each patent number is followed by either a CA abstract number and a complete history of all equivalent documents, or a cross-reference to the patent number of the first abstracted patent in the patent family. This feature of the index, detailing a patent family, is the CA Patent Concordance.
