III. Matters concerning abstracting, classifying, reclassifying and indexing of technical information contained in patent documents

Abstracting, reviewing, translating

All granted patents and registered Utility models are issued with abstract on the first page. All applications for patents are published with abstracts.

Classification1, preclassification2 (if applicable), and reclassification3 activities; Classification system used, e.g., International Patent Classification (IPC), other classification (please indicate whether or not patent documents are classified by your Office and, if so, which classification is used)

The 8-th edition of IPC classification, has been used since January 1, 2006.
In 2009 the current version of advanced level of IPC 8 was used to classify the new applications and published at present documents

Bibliographic data and full-text processing

The abstracts and titles were translated to English and were entered into Common Software-patents database on Bulgarian and English languages.

File building

The Central Patent Library has continued to maintain and update the specialized files on paper and CD-ROM. The collections of paper documents are arranged according to the IPC classification.


Monthly completion of library funds

Storage, including mass storage media

The data is stored mainly in a paper version (dossiers) and electronically (official database, hard discs). In the year under revue The BPO made an inventory of all paper dossiers of patent documents stored in Central Patent Library’s funds.

Documentation from other offices maintained and/or considered part of the available search file

In 2009 the specialized search file (on paper) for the examination including the patent documents/first pages of Bulgaria, Germany, Great Britain and Russia applications has been continuously maintained and updated.

X. Other relevant matters

1.Classification is allotting one or more classification symbols (e.g., IPC symbols) to a patent application, either before or during search and examination, which symbols are then published with the patent application.

2.Preclassification is allotting an initial broad classification symbol (e.g., IPC class or subclass, or administrative unit) to a patent application, using human or automated means for internal administrative purposes (e.g., routing an application to the appropriate examiner).  Usually preclassification is applied by the administration of an office.

3.Reclassification is the reconsideration and usually the replacement of one or more previously allotted classification symbols to a patent document, following a revision and the entry into force of a new version of the Classification system (e.g., the IPC).  The new symbols are available on patent databases.
