Rights conferred by a European patent application after publication
(1) A European patent application shall, from the date of its publication,
provisionally confer upon the applicant the protection provided for by Arti-
cle 64, in the Contracting States designated in the application.
(2) Any Contracting State may prescribe that a European patent applica-
tion shall not confer such protection as is conferred by Article 64. However,
the protection attached to the publication of the European patent applica-
tion may not be less than that which the laws of the State concerned attach
to the compulsory publication of unexamined national patent applications.
In any event, each State shall ensure at least that, from the date of publica-
tion of a European patent application, the applicant can claim compensa-
tion reasonable in the circumstances from any person who has used the in-
vention in that State in circumstances where that person would be liable
under national law for infringement of a national patent.
(3) Any Contracting State which does not have as an official language
the language of the proceedings may prescribe that provisional protection
in accordance with paragraphs 1 and 2 above shall not be effective until
such time as a translation of the claims in one of its official languages at the
option of the applicant or, where that State has prescribed the use of one
specific official language, in that language:
(a) has been made available to the public in the manner prescribed by
national law, or
(b) has been communicated to the person using the invention in the said
State.
(4) The European patent application shall be deemed never to have had
the effects set out in paragraphs 1 and 2 when it has been withdrawn,
deemed to be withdrawn or finally refused. The same shall apply in respect
of the effects of the European patent application in a Contracting State the
designation of which is withdrawn or deemed to be withdrawn.

protection conferred by the European patent application shall be deter-
mined by the claims contained in the application as published. However,

revocation proceedings shall determine retroactively the protection con-
ferred by the application, in so far as such protection is not thereby extend-

(2) If, however, the European patent application has been filed in a lan-
guage which is not an official language of the European Patent Office, that
text shall be the application as filed within the meaning of this Convention.
(3) Any Contracting State may provide that a translation into one of its of-
ficial languages, as prescribed by it according to this Convention, shall in
that State be regarded as authentic, except for revocation proceedings, in
the event of the European patent application or European patent in the lan-
guage of the translation conferring protection which is narrower than that
conferred by it in the language of the proceedings.
(4) Any Contracting State which adopts a provision under paragraph 3:
(a) shall allow the applicant for or proprietor of the patent to file a cor-
rected translation of the European patent application or European patent.

Priority right
(1) Any person who has duly filed, in or for
(a) any State party to the Paris Convention for the Protection of Industrial
Property or
(b) any Member of the World Trade Organization,
an application for a patent, a utility model or a utility certificate, or his suc-
cessor in title, shall enjoy, for the purpose of filing a European patent appli-
cation in respect of the same invention, a right of priority during a period of
twelve months from the date of filing of the first application.
(2) Every filing that is equivalent to a regular national filing under the na-
tional law of the State where it was made or under bilateral or multilateral
agreements, including this Convention, shall be recognised as giving rise to
a right of priority.
(3) A regular national filing shall mean any filing that is sufficient to estab-
lish the date on which the application was filed, whatever the outcome of
the application may be.
(4) A subsequent application in respect of the same subject-matter as a
previous first application and filed in or for the same State shall be consid-
ered as the first application for the purposes of determining priority, provid-
ed that, at the date of filing the subsequent application, the previous appli-
cation has been withdrawn, abandoned or refused, without being open to
public inspection and without leaving any rights outstanding, and has not
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.

which is not subject to the Paris Convention for the Protection of Industrial
Property or the Agreement Establishing the World Trade Organization, par-
agraphs 1 to 4 shall apply if that authority, according to a communication
issued by the President of the European Patent Office, recognises that a

ority under conditions and with effects equivalent to those laid down in the
Paris Convention.

Claiming priority
(1)
85
An applicant desiring to take advantage of the priority of a previous
application shall file a declaration of priority and any other document re-
quired, in accordance with the Implementing Regulations.
(2) Multiple priorities may be claimed in respect of a European patent
application, notwithstanding the fact that they originated in different coun-
tries. Where appropriate, multiple priorities may be claimed for any one
claim. Where multiple priorities are claimed, time limits which run from the
date of priority shall run from the earliest date of priority.
(3) If one or more priorities are claimed in respect of a European patent
application, the right of priority shall cover only those elements of the Euro-
pean patent application which are included in the application or applications
whose priority is claimed.
(4) If certain elements of the invention for which priority is claimed do not
appear among the claims formulated in the previous application, priority
may nonetheless be granted, provided that the documents of the previous

sions and the Legal Division shall not be public.
(4) Oral proceedings, including delivery of the decision, shall be public,
as regards the Boards of Appeal and the Enlarged Board of Appeal, after
publication of the European patent application, and also before the Opposi-

(1) An applicant for or proprietor of a European patent who, in spite of all
due care required by the circumstances having been taken, was unable to
observe a time limit vis-à-vis the European Patent Office shall have his
rights re-established upon request if the non-observance of this time limit
has the direct consequence of causing the refusal of the European patent
application or of a request, or the deeming of the application to have been
withdrawn, or the revocation of the European patent, or the loss of any oth-
er right or means of redress.
(2) The European Patent Office shall grant the request, provided that the
conditions of paragraph 1 and any other requirements laid down in the Im-
plementing Regulations are met. Otherwise, it shall reject the request.

serve the time limit shall be deemed not to have ensued.
(4) Re-establishment of rights shall be ruled out in respect of the time
limit for requesting re-establishment of rights. The Implementing Regula-
tions may rule out re-establishment for other time limits.
(5) Any person who, in a designated Contracting State, has in good faith
used or made effective and serious preparations for using an invention
which is the subject of a published European patent application or a Euro-
pean patent in the period between the loss of rights referred to in para-
graph 1 and publication in the European Patent Bulletin of the mention of
re-establishment of those rights, may without payment continue such use in
the course of his business or for the needs thereof.
(6) Nothing in this Article shall limit the right of a Contracting State to
grant re-establishment of rights in respect of time limits provided for in this
Convention and to be observed vis-à-vis the authorities of such State.

Revocation and prior rights
Article 138
167
Revocation of European patents

ticles 52 to 57;
(b) the European patent does not disclose the invention in a manner suf-
ficiently clear and complete for it to be carried out by a person skilled in the
art;
(c)
168
the subject-matter of the European patent extends beyond the con-
tent of the application as filed or, if the patent was granted on a divisional
application or on a new application filed under Article 61, beyond the con-
tent of the earlier application as filed;
(d) the protection conferred by the European patent has been extended;
or
(e) the proprietor of the European patent is not entitled under Article 60,
paragraph 1.

validity of the European patent, the proprietor of the patent shall have the
right to limit the patent by amending the claims. The patent as thus limited
