"[12] Namely, for European patents granted in French or German on or after 3 September 2012, the filing of a translation into English is no longer required in Ireland.

The new language regime however already applied for Switzerland, Liechtenstein and the United Kingdom to European patents granted on or after 1 February 2008.

The original implementation bill was flawed due to miscalculations of the date of entry into force of the new translation requirements for European patents designating Germany.

[20] On 14 April 2010, the Court of Appeal of Paris, France, issued 24 similar court decisions, holding that, since France has ratified the London Agreement, no translation in French needed to be filed at the French Patent Office (INPI) with respect of European patents maintained as amended after opposition proceedings, and that this applied also to European patents maintained as amended for which the original mention of grant has been published prior to the entry into force of the London Agreement.

On 18 April 2007, at the European Patent Forum in Munich, Germany, Angela Merkel said that she and German Justice Minister Brigitte Zypries would fight to see the London Agreement realised.

[28] This agreement was signed by 10 countries, namely Denmark, France, Germany, Liechtenstein, Luxembourg, Monaco, Netherlands, Sweden, Switzerland and the United Kingdom.

To enter into force, the deposit of instruments of ratification by at least eight countries, including at least France, Germany and the United Kingdom had to take place.

Up to now, Monaco, Germany, United Kingdom, Switzerland, Netherlands, Liechtenstein, Luxemburg, Denmark, and France have deposited their instrument of ratification to the London Agreement while Slovenia, Iceland, Latvia and Croatia have deposited their instrument of accession (accession is also taken into account for the entry into force of the agreement).
