Trademarks in Portugal


A trademark is a sign that is registered to distinguish a product or service in commerce. There are other types of signs used in trade that can also be registered with the INPI (Portuguese Institute of Industrial Property), such as logos, designations of origin, geographical indications, collective marks and certification or guarantee marks.

Trademark Search in Portugal

Trademark Search in Portugal can be conducted through INPI’s website by name, phonetic, application number, by applicant/owner, by product or service and by unconventional trademarks. Search can also be conducted for images and for integrated trademark and domain name search.

It is advisable to conduct a trademark search prior to filing of a trademark application in order to ascertain the availability of trademarks, existence of prior identical/similar/ deceptively marks on the register etc., so as to avoid any objection and opposition with respect to the mark.

Additionally is advisable to conduct comprehensive trademark clearance search to ascertain availability of the proposed mark and also to overcome any objection and opposition with respect to mark later on.
