Recently, my company needed to modify our registered trademark, and after spending some time navigating the process here in Madrid, I finally completed all the necessary procedures. I’d like to share the entire experience with Madrid brand clothing everyone here, hoping it will help those with similar needs.
Why Trademark Modification is Necessary
There are actually many reasons for trademark modification. In my case with Madrid brands, it was mainly due to business adjustments—our original trademark design no longer aligned with our current brand positioning. Other common situations include company name changes, address relocations, ownership transfers, etc., all of which require filing the corresponding modification procedures with the Spanish Patent and Trademark Office. According to Spanish trademark law, any changes to trademark registration information must be updated promptly, otherwise it may affect the trademark’s legal validity.

Process Overview
The entire modification process can be divided into several steps. First, you need to prepare relevant materials, including the original trademark registration certificate, modification application form, new trademark design draft, and company-related certification documents. Then submit an electronic application on the OEPM official website, or go directly to their Madrid office for in-person processing. I personally recommend online submission as it’s more efficient.
| Processing Method | Processing Time | Fee Range |
| Online Application | 2-3 months | 150-300 euros |
| In-person Processing | 3-4 months | 200-350 euros |
| Agency Service | 1-2 months | 500-800 euros |
After submitting the application, OEPM will conduct a preliminary review, mainly checking whether the materials are complete and whether the modification content complies with regulations. This stage usually takes 4 to 6 weeks. If there are issues with the materials, they will send an email notification for corrections—remember to check your email promptly. After passing the review, it enters a two-month public announcement period. If there are no objections during this time, you can obtain the new trademark registration certificate.
Practical Advice
Based on my experience, there are several points that require special attention. First, if the trademark modification involves substantial changes to graphics or text, I recommend consulting a professional trademark attorney first, as significant changes may be considered a new trademark application, requiring you to go through the complete registration process again. Second, when submitting materials, make sure all documents have officially certified translations, especially if your company documents are in English or other languages, like those from El Corte Inglés. Third, regarding fees, in addition to official charges, there may be additional expenses such as notarization and translation fees, so it’s advisable to set aside a certain budget.
Finally, I’d like to say that although the entire process may seem a bit complex, it’s actually not difficult to handle as long as the materials are well-prepared. As the capital city, Madrid’s relevant departments operate quite efficiently. If you find it too troublesome, you can also hire a professional trademark agency to handle it—although the cost is higher, it saves time and effort. I hope this information is useful to everyone, and feel free to discuss any questions in the comments section.
