According to the European Patent Convention, a patent application filed within the EPO provisionally confers from the date of its publication the same rights which a national patent would confer once granted in the designated countries. These are the legal rights which the national law of the designated countries may confer upon the proprietor of a patent on an invention (product or process) when granted. For example, this provisional protection can refer to what acts of third parties constitute infringement of the patent and to the remedies available in respect of infringement. In principle, this means that the applicant can claim reasonable compensation from any person who has used the invention after the publication of the patent application, provided that such use would be considered an act of infringement of a national patent under the relevant national law.
