Can I change the bibliographic data for my application at any time?

The bibliographic data for an application includes the title of the invention, classification of the invention, the date of filing, and information about the applicants, designated states in which patent protection is requested, priority claims and inventors.

You won’t be allowed to change the classification or date of filing of the application, as this is information that the EPO determines on initial filing and during the search and examination steps.

However, you may request changes for the other data at any time up to publication of the granted patent: title of the invention, classification of the invention, the applicants, designated states, priority claims and inventors.
