Deadline for validating european patent
Thus, the filing costs, and the costs of the subsequent application procedure, should be significantly lower than the equivalent costs of filing individual national patent applications, which in most cases must each be carried out in the national language.
For example, you may wish to file initially a relatively cheap UK patent application at an early stage in the development of your invention, in order to establish a priority date.
Following this first filing, you have a year to develop your invention further, and to work out whether it is commercially viable, before you have to decide whether to invest in a European patent.
It is possible to file an application for a European patent without claiming any priority.
It is also possible to make a European patent application via an international application under the Patent Cooperation Treaty (PCT).
We can provide you with further information about these options if you wish.
European patent applications can be filed at the European Patent Office (EPO) in English.
