Patent filing in Greece is handled by the Hellenic Industrial Property Organisation (OBI). Applicants submit a specification, claims, drawings, and abstract, followed by formal and substantive examination. Greece operates mainly as a registration system with a search report rather than full examination of inventiveness. Protection lasts 20 years from filing, subject to annual renewal fees. Foreign applicants must appoint a local representative. European Patent validation in Greece is also available.
