Rule 33

Form and content of the abstract

Art. 78, 85, 93
R. 36, 47



(1) The abstract shall indicate the title of the invention.


(2) The abstract shall contain a concise summary of the disclosure as contained in the description, the claims and any drawings; the summary shall indicate the technical field to which the invention pertains and shall be drafted in a way which allows the clear understanding of the technical problem, the gist of the solution of that problem through the invention and the principal use or uses of the invention. The abstract shall, where applicable, contain the chemical formula which, among those contained in the application, best characterises the invention. It shall not contain statements on the alleged merits or value of the invention or on its speculative application.


(3) The abstract shall preferably not contain more than one hundred and fifty words.


(4) If the European patent application contains drawings, the applicant shall indicate the figure or, exceptionally, the figures of the drawings which he suggests should accompany the abstract when the abstract is published. The European Patent Office may decide to publish one or more other figures if it considers that they better characterise the invention. Each main feature mentioned in the abstract and illustrated by a drawing shall be followed by a reference sign, placed between parentheses.


(5) The abstract shall be so drafted that it constitutes an efficient instrument for purposes of searching in the particular technical field particularly by making it possible to assess whether there is a need for consulting the European patent application itself.
