Where to file: The European patent application may be filed (a) at the European Patent Office in Munich, at its branch in The Hague, or at one of its sub-offices in Berlin, Vienna or Brussels; or (b) if the law of a Contracting State so permits or prescribes, at the central Industrial Property Office of that State. 

Official languages: English, French and German. Residents of a Contracting State having another language may file an application in that language, and supply, within one month, a translation into one of the official EPO languages.
Designation of the contracting states: All Contracting States are automatically designated when filing. One designation fee for designating all States (effective since 2009).


Duration and renewal: Duration is twenty years from the date of filing. Renewal fees for the third year and each subsequent year must be paid to the EPO for European patent applications. After the publication of the mention of the grant, further renewal fees have to be paid separately in each designated Contracting State according to the national patent laws.
Effects of a granted patent: A granted European patent shall confer in each Contracting State for which it is granted the same rights as would be conferred by a national patent.
National Phase: All Contracting States have enacted provisions, that if the text of a European patent is not drawn up in one of the official national languages, a translation of the text must be supplied. The translations must be filed in the respective designated Contracting States within three months (six months in Ireland) after the publication of the mention of the grant. However, since the entry into force of the "London Agreement", countries that have an official language that is also an official language of the EPO (i.e. English, French or German) will no longer require the translation of a European patent, even if the language in which the patent is granted is not an official language of the country. Other countries can choose one of the official languages as a "prescribed language" into which European patents will have to be translated in order to enter into force in their country.
Opposition: Within nine months from the publication of the granting decision, any person (except the patent owner) may give notice to the EPO of opposition to the patent granted.

The Eurasian Patent Convention entered into force on August 12, 1995, after ratification by four countries. The Convention allows the filing of one patent application in the Russian language with an automatic designation of all Member States.

The following nine States have so far ratified the convention: Armenia, Azerbaijan, Belarus, Kazakhstan, Kyrgyzstan, Moldova (denunciation of the Convention with effect from April 26, 2012), the Federation of Russia, Tajikistan, Turkmenistan.

After the grant of a Eurasian Patent, the patentee shall indicate in which Member States he desires to maintain the patent. Fees are then due with respect to each Member State. As of January 1, 1996, it is possible to designate the Eurasian regional phase in a PCT application, (as for the EP-regional phase), the designation including all countries for which the Convention is in force at that point in time. The Eurasian Patent Office also accepts direct applications. The Office is located in Moscow where a complete examination is carried out, including grant and issuance of a single patent document. After-grant aspects (validity, infringement, etc.) are handled by the national authorities.
