The PCT procedure facilitates the processing of applications for protecting inventions when this protection is required in a number of countries. It establishes a system through which a single application submission produces the same effects as if the application were submitted in each one of the countries that form part of the PCT Treaty.
The SPTO acts as a receiving office for international PCT applications whose holders are Spanish or legal residents of Spain.
The SPTO is also an International Search and Preliminary Examining Authorities.
Two programs can be used for electronic filing: one distributed by the European Patent Office, EPO Online Filing (eOLF), and one provided by the International Bureau of WIPO, PCT-SAFE. Both are free of charge.
