International Patent Classification is meant for classification of the inventions in the field of science, engineering and technology according to a uniform system on the basis of the Strasbourg Agreement Concerning the International Patent Classification (IPC).

The Strasbourg Agreement was concluded in 1971 and it entered into force in 1975. The Classification has periodically been revised. The eighth edition of the IPC entered into force on 1 January 2006.

The Republic of Estonia acceded to the Strasbourg Agreement Concerning the International Patent Classification (IPC) on 27 February 1997 (Strasbourg Notification No. 45 27.02.1996).

Besides, Estonia acceded to the Special Union established on the basis of the Agreement and became the 34th member of the Union. At present 55 States is party to the Agreement.

The publication consists of two parts: a guide how to use the 8th edition of the IPC and a list of sections and classes of the classification. The text of the Strasbourg Agreement Concerning the International Patent Classification (IPC) and the law of accession to the Agreement as well as the list of the countries parties to this Agreement have been provided in the Annex of the publication.

Before filing a patent application the creator of a new technical or technological solution should find out similar solutions and on the basis of them determine its novelty and decide if it exceeds the previous state of art.

Careful and precise use of the Classification enables to decrease the volume of the search as well as expenditure of time.
