Notices - cont<br />

The range of specification numbers covered by Series C and D File Lists depends upon the<br />

Heading (or Part-Heading) concerned and the extent of backlogging following relevant<br />

revisions of the Classification key; this is because it has not always been necessary or<br />

efficient to backlog a new revision fully. Appropriate details are given in the Documentation<br />

Record of Each Heading (or Part-Heading), including information on how to retrieve relevant<br />

patent documents by series C or D file Lists as far back as the computer records go, using<br />

earlier editions of the Key if appropriate.<br />

In addition, as stated above, Series A File Lists are also available, and may need to be<br />

ordered if all relevant specifications below 1000001 are required to be retrieved, as the<br />

Series C and D File Lists do not necessarily contain all relevant specifications published<br />

before number 1000001. Further information may be obtained from Classification and<br />

Documentation Division or the Search and Advisory Service.<br />

In Headings where recent classification work has been carried out the information given in<br />

the Documentation record of the Heading may not be up to date. In such cases<br />

Classification and Documentation Division should be consulted for the latest situation.<br />

Each file list is produced to fulfil a specific order, however a set of the Series A File Lists is<br />

available for reference in the British Library.<br />

It will be appreciated if any instance of incorrect classification or indexing is brought to the<br />

notice of Classification and Documentation Division.<br />

The practice of classifying and indexing all published EP and PCT applications on the UK<br />

Classification Key ceased from specifications numbered EP 0285000 and WO1989/000001<br />

onwards and therefore, subject to certain exceptions set out below, EP and PCT<br />

applications published from these numbers will not appear on subject-matter file lists based<br />

on the provisions of the UK Key.<br />

Classification Manual<br />

A Manual is available which explains in detail the system used for Heading C2C. It also<br />

contains notes and examples on both indexing and searching and will thus be found helpful<br />

by all those using this heading for Search purposes, especially be way of Series C and D file<br />

lists.<br />

Heading C2C, Organic Compounds:<br />

Manual for the Computer Retrieval System “Organic Compounds” C2C.<br />

The latest edition of the C2C Manual which replaced the 1974 edition and its<br />

supplements was published to coincide with Edition I of the Classification Key. Copies<br />

are available from Sales price £25.00.<br />

This Manual is used in the UK <strong>Patent</strong> <strong>Office</strong> for all searches within the field of organic<br />

chemistry corresponding to Heading “C2C - Organic compounds” of the UK<br />

Classification Key, and was developed by the co-operative effort of some 30<br />

examiners and analysts. It first became operative in April 1974 with the exception of a<br />

few classifying and indexing terms which became operative later.<br />

Since 1974 there have been a number of changes to, or affecting the system. The<br />

major changes are summarized in Appendix F of the latest edition.
