Which filings entitle to a priority right?



Article 4 A (2) Paris Convention

Any filing that is equivalent to a regular national filing under the domestic legislation of any country of the Union or under bilateral or multilateral treaties concluded between countries of the Union shall be recognized as giving rise to the right of priority.



In order to entitle an applicant, or his successor in title to a priority right, the first filing must be either a regular national filing


This wording does not include verbatim regional filings, such as a European patent application, or an international application under the PCT. However, regional and international filings, are usually considered by the domestic legislation as equivalent to national filings, as as a conseqeunce o fthe regional or international filing a national patent may be obtained. For example the German Inventor renumeration act prescribed that when an invention disclosure was accepted by the employer he had an obligation to file a national application (patent or utility model). As the German Inventor renumeration Act was older than the European Patent Convention, it was silent if an employer that had filed a regional application had fulfilled his legal obligation when filing a European patent application. The German Supreme Court however decided, that a European patent application was equivalent to a national German patent application.
