Adversarial and non-adversarial proceedings

Opposition, limitation or revocation procedure

At the request of the proprietor, the European patent may be revoked or be limited by an amendment of the claims. The request shall be filed with the European Patent Office in accordance with the Implementing Regulations. It shall not be deemed to have been filed until the limitation or revocation fee has been paid.

The request may not be filed while opposition proceedings in respect of the European patent are pending.

The European Patent Office shall examine whether the requirements laid down in the Implementing Regulations for limiting or revoking the European patent have been met. If the European Patent Office considers that the request for limitation or revocation of the European patent meets these requirements, it shall decide to limit or revoke the European patent in accordance with the Implementing Regulations. Otherwise, it shall reject the request. The decision to limit or revoke the European patent shall apply to the European patent in all the Contracting States in respect of which it has been granted. It shall take effect on the date on which the mention of the decision is published in the European Patent Bulletin. 

If the European patent is limited, the European Patent Office shall publish the amended specification of the European patent as soon as possible after the mention of the limitation has been published in the European Patent Bulletin.

Within nine months of the publication of the mention of the grant of the European patent in the European Patent Bulletin, any person may give notice to the European Patent Office of opposition to that patent, in accordance with the Implementing Regulations. Notice of opposition shall not be deemed to have been filed until the opposition fee has been paid. The opposition shall apply to the European patent in all the Contracting States in which that patent has effect. Opponents shall be parties to the opposition proceedings as well as the proprietor of the patent. Where a person provides evidence that in a Contracting State, following a final decision, he has been entered in the patent register of such State instead of the previous proprietor, such person shall, at his request, replace the previous proprietor in respect of such State.

Opposition may only be filed on the grounds that: 

(a) the subject-matter of the European patent is not patentable;

(b) the European patent does not disclose the invention in a manner sufficiently clear and complete for it to be carried out by a person skilled in the art.

If the opposition is admissible, the Opposition Division shall examine, in accordance with the Implementing Regulations, whether at least one ground for opposition prejudices the maintenance of the European patent. During this examination, the Opposition Division shall invite the parties, as often as necessary, to file observations on communications from another party or issued by itself.

If the Opposition Division is of the opinion that at least one ground for opposition prejudices the maintenance of the European patent, it shall revoke the patent. Otherwise, it shall reject the opposition. 

If the Opposition Division is of the opinion that, taking into consideration the amendments made by the proprietor of the European patent during the opposition proceedings, the patent and the invention to which it relates 

(a) meet the requirements of this Convention, it shall decide to maintain the patent as amended, provided that the conditions laid down in the Implementing Regulations are fulfilled; 

(b) do not meet the requirements of this Convention, it shall revoke the patent. 

If the European patent is maintained as amended, the European Patent Office shall publish a new specification of the European patent as soon as possible after the mention of the opposition decision has been published in the European Patent Bulletin.

Each party to the opposition proceedings shall bear the costs it has incurred, unless the Opposition Division, for reasons of equity, orders, in accordance with the Implementing Regulations, a different apportionment of costs. 

The procedure for fixing costs shall be laid down in the Implementing Regulations. Any final decision of the European Patent Office fixing the amount of costs shall be dealt with, for the purpose of enforcement in the Contracting States, in the same way as a final decision given by a civil court of the State in which enforcement is to take place. Verification of such decision shall be limited to its authenticity. 

Any third party may, in accordance with the Implementing Regulations, intervene in opposition proceedings after the opposition period has expired, if the third party proves that  

(a) proceedings for infringement of the same patent have been instituted against him, or 

(b) following a request of the proprietor of the patent to cease alleged infringement, the third party has instituted proceedings for a ruling that he is not infringing the patent. 

An admissible intervention shall be treated as an opposition. 

European Patent

Term of the European patent

The term of the European patent shall be 20 years from the date of filing of the application.

Nothing in the preceding paragraph shall limit the right of a Contracting State to extend the term of a European patent, or to grant corresponding protection which follows immediately on expiry of the term of the patent, under the same conditions as those applying to national patents: 

(a) in order to take account of a state of war or similar emergency conditions affecting that State; 

(b) if the subject-matter of the European patent is a product or a process for manufacturing a product or a use of a product which has to undergo an administrative authorisation procedure required by law before it can be put on the market in that State. 

It shall apply mutatis mutandis to European patents granted jointly for a group of Contracting States.


Rights conferred by a European patent

A European patent shall confer on its proprietor from the date on which the mention of its grant is published in the European Patent Bulletin, in each Contracting State in respect of which it is granted, the same rights as would be conferred by a national patent granted in that State.

If the subject-matter of the European patent is a process, the protection conferred by the patent shall extend to the products directly obtained by such process.

Any infringement of a European patent shall be dealt with by national law. 

The European patent application and the resulting European patent shall be deemed not to have had, from the outset to the extent that the patent has been revoked or limited in opposition, limitation or revocation proceedings.


Extent of protection

The extent of the protection conferred by a European patent or a European patent application shall be determined by the claims. Nevertheless, the description and drawings shall be used to interpret the claims.

For the period up to grant of the European patent, the extent of the protection conferred by the European patent application shall be determined by the claims contained in the application as published. However, the European patent as granted or as amended in opposition, limitation or revocation proceedings shall determine retroactively the protection conferred by the application, in so far as such protection is not thereby extended.

In any designated Contracting State a European patent application and a European patent shall have with regard to a national patent application and a national patent the same prior right effect as a national patent application and a national patent. A national patent application and a national patent in a Contracting State shall have with regard to a European patent designating that Contracting State the same prior right effect as if the European patent were a national patent. Any Contracting State may prescribe whether and on what terms an invention disclosed in both a European patent application or patent and a national application or patent having the same date of filing or, where priority is claimed, the same date of priority, may be protected simultaneously by both applications or patents. 

Examination of European patent application

In proceedings before it, the European Patent Office shall examine the facts of its own motion; it shall not be restricted in this examination to the facts, evidence and arguments provided by the parties and the relief sought. The European Patent Office may disregard facts or evidence which are not submitted in due time by the parties concerned.

In proceedings before the European Patent Office the means of giving or obtaining evidence shall include the following: 

(a) hearing the parties; 

(b) requests for information; 

(c) production of documents; 

(d) hearing witnesses; 

(e) opinions by experts; 

(f) inspection; 

(g) sworn statements in writing.

The European Patent Office may, in accordance with the Implementing Regulations, invite the applicant to provide information on prior art taken into consideration in national or regional patent proceedings and concerning an invention to which the European patent application relates. If the applicant fails to reply in due time to an invitation, the European patent application shall be deemed to be withdrawn.

The European Patent Office shall examine, in accordance with the Implementing Regulations, whether the application satisfies the requirements for the accordance of a date of filing.

If a date of filing cannot be accorded, the application shall not be dealt with as a European patent application.

If the European patent application has been accorded a date of filing, the European Patent Office shall examine, in accordance with the Implementing Regulations as well as any other requirement laid down in the Implementing Regulations.

Where the European Patent Office in carrying out the examination notes that there are deficiencies which may be corrected, it shall give the applicant an opportunity to correct them.

If any deficiency noted in the examination is not corrected, the European patent application shall be refused unless a different legal consequence is provided for by this Convention. Where the deficiency concerns the right of priority, this right shall be lost for the application.

The European Patent Office shall, in accordance with the Implementing Regulations, draw up and publish a European search report in respect of the European patent application on the basis of the claims, with due regard to the description and any drawings.

The European Patent Office shall, in accordance with the Implementing Regulations, examine on request whether the European patent application and the invention to which it relates meet the requirements of this Convention. The request shall not be deemed to be filed until the examination fee has been paid.

If no request for examination has been made in due time, the application shall be deemed to be withdrawn.

If the examination reveals that the application or the invention to which it relates does not meet the requirements of the Convention, the Examining Division shall invite the applicant, as often as necessary, to file his observations and to amend the application.

If the applicant fails to reply in due time to any communication from the Examining Division, the application shall be deemed to be withdrawn.

An applicant claiming priority shall file a copy of the results of any search carried out by the authority with which the previous application was filed together with the European patent application, in the case of a Euro-PCT application on entry into the European phase, or without delay after such results have been made available to him. The copy shall be deemed to be duly filed if it is available to the European Patent Office and to be included in the file of the European patent application under the conditions determined by the President of the European Patent Office. The European Patent Office may invite the applicant to provide, within a period of two months, information on prior art.

Proceedings before the European Patent Office shall be interrupted: 

(a) in the event of the death or legal incapacity of the applicant for or proprietor of a European patent or of the person authorised by national law to act on his behalf. To the extent that the above events do not affect the authorisation of a representative as appointed, proceedings shall be interrupted only on application by such representative;

(b) in the event of the applicant for or proprietor of a patent, as a result of some action taken against his property, being prevented by legal reasons from continuing the proceedings; 

(c) in the event of the death or legal incapacity of the representative of an applicant for or proprietor of a patent, or of his being prevented for legal reasons resulting from action taken against his property from continuing the proceedings. 

When, in the cases, the European Patent Office has been informed of the identity of the person authorised to continue the proceedings, it shall notify such person and, where applicable, any third party, that the proceedings will be resumed as from a specified date.

Filing of a European patent application

In proceedings before the European Patent Office, documents may be filed by delivery by hand, by postal services or by means of electronic communication. The President of the European Patent Office shall lay down the details and conditions and, where appropriate, any special formal or technical requirements for the filing of documents. In particular, he may specify that confirmation must be supplied. If such confirmation is not supplied in due time, the European patent application shall be refused; documents filed subsequently shall be deemed not to have been received.

Where the Convention provides that a document must be signed, the authenticity of the document may be confirmed by handwritten signature or other appropriate means the use of which has been permitted by the President of the European Patent Office. A document authenticated by such other means shall be deemed to meet the legal requirements of signature in the same way as a document bearing a handwritten signature which has been filed in paper form.

A European patent application may be filed: 

(a) with the European Patent Office, or 

(b) if the law of a Contracting State so permits with the central industrial property office or other competent authority of that State. Any application filed in this way shall have the same effect as if it had been filed on the same date with the European Patent Office.

The central industrial property office of a Contracting State shall forward to the European Patent Office any European patent application filed with it or any other competent authority in that State, in accordance with the Implementing Regulations. A European patent application the subject of which has been made secret shall not be forwarded to the European Patent Office. A European patent application not forwarded to the European Patent Office in due time shall be deemed to be withdrawn. 

A European divisional application shall be filed directly with the European Patent Office in accordance with the Implementing Regulations. It may be filed only in respect of subject-matter which does not extend beyond the content of the earlier application as filed; in so far as this requirement is complied with, the divisional application shall be deemed to have been filed on the date of filing of the earlier application and shall enjoy any right of priority. All the Contracting States designated in the earlier application at the time of filing of a European divisional application shall be deemed to be designated in the divisional application.

European patent applications may be filed in writing with the European Patent Office in Munich, The Hague or Berlin, or the National authorities. The authority with which the European patent application is filed shall mark the documents making up the application with the date of their receipt, and issue without delay a receipt to the applicant including at least the application number and the nature, number and date of receipt of the documents. 

If the European patent application is filed with an authority, such authority shall without delay inform the European Patent Office of the receipt of the application, and, in particular, of the nature and date of receipt of the documents, the application number and any priority date claimed.

Upon receipt of a European patent application forwarded by the central industrial property office of a Contracting State, the European Patent Office shall inform the applicant accordingly, indicating the date of its receipt. 

The applicant may file a divisional application relating to any pending earlier European patent application. 

A divisional application shall be filed in the language of the proceedings for the earlier application. If the latter was not in an official language of the European Patent Office, the divisional application may be filed in the language of the earlier application; a translation into the language of the proceedings for the earlier application shall then be filed within two months of the filing of the divisional application. The divisional application shall be filed with the European Patent Office in Munich, The Hague or Berlin. The filing fee and search fee shall be paid within one month of filing the divisional application. If the filing fee or search fee is not paid in due time, the application shall be deemed to be withdrawn. The designation fee shall be paid within six months of the date on which the European Patent Bulletin mentions the publication of the European search report drawn up in respect of the divisional application.

The filing fee and search fee shall be paid within one month of filing the European patent application. The Rules relating to Fees may provide for an additional fee as part of the filing fee if the application comprises more than 35 pages. The additional fee shall be paid within one month of filing the European patent application or one month of filing the first set of claims or one month of filing the certified copy, whichever period expires last.

The designation fee shall be paid within six months of the date on which the European Patent Bulletin mentions the publication of the European search report. Where the designation fee is not paid in due time or the designations of all the Contracting States are withdrawn, the European patent application shall be deemed to be withdrawn.

The date of filing of a European patent application shall be the date on which the documents filed by the applicant contain: 

(a) an indication that a European patent is sought; 

(b) information identifying the applicant or allowing the applicant to be contacted; and 

(c) a description or reference to a previously filed application. 

A reference to a previously filed application shall state the filing date and number of that application and the Office with which it was filed. Such reference shall indicate that it replaces the description and any drawings.

Where the application contains a reference, a certified copy of the previously filed application shall be filed within two months of filing the application. Where the previously filed application is not in an official language of the European Patent Office, a translation thereof in one of these languages shall be filed within the same period.
