utility model, or of an industrial design, or of a trademark, in one of the countries of the Union,
or his successor in title, shall enjoy, for the purpose of filing in the other countries, a right of
priority during the periods hereinafter fixed. (2) Any filing that is equivalent to a regular national filing under the domestic legislation of
any country of the Union or under bilateral or multilateral treaties concluded between countries
of the Union shall be recognized as giving rise to the right of priority. (3) By a regular national filing is meant any filing that is adequate to establish the date on
which the application was filed in the country concerned, whatever may be subsequent fate of
the application. B.

is adequate to establish the date on
which the application was filed in the country concerned, whatever may be subsequent fate of
the application. B.

Consequently, any subsequent filing in any of the other countries of the Union before the
expiration of the periods referred to above shall not be invalidated by reason of any acts
accomplished in the interval, the particular, another filing, the publication or exploitation of

the invention, the putting on sale of copies of the design, or the use of the mark, and such acts
cannot give rise to any third-party right or any right of personal possession. Rights acquired by
third parties before the date of the first application that serves as the basis of the right of priority
are reserved in accordance with the domestic legislation of each country of the Union. C. (1) The periods of priority referred to above shall be twelve months for patents and utility
models, and six months for industrial designs and trademarks. (2) These periods shall start from the date of filing of the first application; the day of filing

(4) A subsequent application concerning the same object as a previous first application within
the meaning of paragraph (2), above, filed in the same country of the Union, shall be considered
as the first application, of which the filing date shall be the starting point of the period of
priority, if, at the time of filing the subsequent application, the said previous application has
been withdrawn, abandoned, or refused, without having been laid open to public inspection
and without leaving any rights outstanding, and if it has not yet served as a basis for claiming
a right of priority. The previous application may not thereafter serve as a basis for claiming a
right of priority. D. (1) Any person desiring to take advantage of the priority of a previous filing shall be required
to make a declaration indicating the date of such filing and the country in which it was made. Each country shall determine the latest date on which such declaration must be made. (2) These particulars shall be mentioned in the publications issues by the competent authority,

certified as correct by the authority which received such application, shall not require any
authentication, and may in any case be filed, without fee, at any time within three months of
the filing of the subsequent application. They may require it to be accompanied by a certificate
from the same authority showing the date of filing, and by a translation. (4) No other formalities may be required for the declaration of priority at the time of filing the
application. Each country of the Union shall determine the consequences of failure to comply
with the formalities prescribed by this Article, but such consequences shall in no case go
beyond the loss of the right of priority. (5) Subsequently, further proof may be required. Any person who avails himself of the priority of a previous application shall be required to

(2) Furthermore, it is permissible to file a utility model in a country by virtue of a right of
priority based on the filing of a patent application, and vice versa. F. No country of the Union may refuse a priority or a patent application on the ground that the
applicant claims multiple priorities, even if they originate in different countries, or on the
ground that an application claiming one or more priorities contains one or more elements that
were not included in the application or applications whose priority is claimed, provided that,
in both cases, there is unity of invention within the meaning of the law of the country. With respect to the elements not included in the application or applications whose priority is
claimed, the filing of the subsequent application shall give rise to a right of priority under
ordinary conditions. G. (1) If the examination reveals that an application for a patent contains more than one

right of priority, if any. Each country of the Union shall have the right to determine the
conditions under which such division shall be authorized. H. Priority may not be refused on the ground that certain elements of the invention for which
priority is claimed do not appear among the claims formulated in the application in the country
of origin, provided that the application documents as a whole specifically disclose such
elements. I. (1) Applications for inventors’ certificates filed in a country in which applicants have the
right to apply at their own option either for a patent or for an inventor's certificate shall give
