Dear Josh,

Thank you for your email.

Yes, we would recommend proceeding with payment of the registration fees, even if the mark is not currently in use in Venezuela, particularly since the client has indicated that there is potential interest in using the mark in the future.

In Venezuela, there is no use requirement to obtain registration, and the Trademark Office does not require registrants to file declarations or evidence of use to maintain a registration. However, once granted, a registration may become vulnerable to cancellation for non-use after two years from the registration date, if a third party with legitimate interest files the corresponding action.

In that case, the owner would need to prove use of the mark in Venezuela to defend the registration.

Accordingly, our recommendation would be to proceed with payment and secure the registration, while keeping the potential non-use vulnerability in mind for future portfolio strategy.

Best regards,
Guillermo

Dear Néstor,

Thank you for your reminder email below. For our reference, can you please advise whether you would recommend the client proceed with paying the registration fee for the below referenced LUDOX mark in the event that the client has not begun using the LUDOX mark in Venezuela? While our client does not yet use the mark in Venezuela, they have indicated that there is a potential for use in the future.

With this information in mind, would it make sense to proceed with paying the registration fee at this time for the LUDOX registration in the event that the client does begin using the mark? Additionally, are there any use-based requirements that we should be aware of in Venezuela that would require our client to demonstrate use of the mark in order to maintain any potential registrations?

If there are any questions, comments, or concerns regarding this request, please let us know.

Best regards,

Josh Evers

Dear Josh,
Thank you for your email. The costs associated with the payment of registration fees and obtaining the certificate are:
Professional Fees
VAT
16%
Official fees
Expenses
Total
$200
$32
$210
$45
$487

This application was opposed by the company LABORATORIO PALENZOLA COMPAÑIA ANÓNIMA INDUSTRIAL, based on its registration for the trademark LUDROX in Class 5. Initially, this opposition was sustained, and the client’s trademark was refused in Official Gazette No. 410, dated April 18, 1997. Against this decision, the client filed a Motion for Reconsideration on May 8, 1997.
After reviewing the case, the Trademark Office has now decided to grant the client’s trademark. Since the opposing party did not appeal this new decision, the grant is now final.
We look forward to hearing from you.
Best regards,

Dear sirs,

We are pleased to inform you that Application No. 1995-000225 for LUDOX in Class 5 filed by W.R. GRACE & CO.-CONN. has been granted.

This application was previously rejected by the VPTO on the basis of the Opposition filed by LABORATORIO PALENZONA COMPAÑÍA ANONIMA INDUSTRIAL.

W.R. GRACE & CO.-CONN filed a Motion for Reconsideration, which was upheld and, consequently, the VPTO reverted the rejection and granted the application.

After the appeal period expired, we confirmed that LABORATORIO PALENZONA COMPAÑÍA ANONIMA INDUSTRIAL did not appeal the decision. Therefore, the registration fees can be paid until 28th April, 2026.

Please confirm if the client maintains interest in this application so we may provide our cost estimate.
