Advice and enquires:

– Technical and legal


1º.-Before proceeding to apply for a trademark, it is advisable to make a Previuos Report to verify that the distinctive mark is not subject to any Absolute Prohibition of registration (generic terms, official emblems, etc…) and that there are no priority similar o equal trademarks that could be an obstacle for its granting.
The deadline to prepare these report is 24 to 48 hours maximum. (48-72 hours in case of graphic searches).
2º.- If the Report is favorable and once we have received all the documentation required (see below: DOCUMENTATION REQUIRED), the trademark will be filed at the OEPM (Spanish Patent and Trademark Office) in the following 24-48 hours.
3º.- Approximately one month since the Application has been filed, it will be published in the BOPI (Industrial Property Official Bulletin). This sets the beginning of the term of two months to initiate an Opposing Procedure by Third Parties who may consider themselves affected by the new application incompatibility.
Once the 60 days period is completed, the OEPM will submit the trademark to an Official Check to warrant that the trademark incurs in any Absolute Prohibition for registration. There is not Official exam for Relative Prohibitions (prior registrations).
4º.- If no oppositions have been received from third parties and the Official Check/exam of the OEPM is favorable, the trademark will be granted and published in the BOPI, therefore a Certificate-Title of Property rights will be issued.
In this case, the registration procedure lasts for an estimated period within four to five months.
The trademark is granted for TEN years, renewable for further periods of ten years from the date of application.

5º.- In case of a suspension due to an opposition or any Absolute Prohibition, the OEPM will publish it in the BOPI which opens a 30 days period from the publication date to file a reply in defense of the trademark. (The normal term for processing could be delayed for another four or five extra months in this case).

Once the reply period has expired, the OEPM will re- examine the file and decide whether the trademark is granted or denied.
6º.- This resolution may be appealed to the OEPM by filling an Appeal to the Resources Unit to reconsider the file.

The resolution of the mentioned Appeal shall end the administrative step. However, in case of disagreement, there is still the possibility to use an administrate-contentious procedure at the Ordinary Courts (through the Court). But this rarely happens due to the high costs and length of the procedures.
