How to register your trademark in class 11 with CheckMarca
Registering a trademark in class 11 with INAPI follows the same process as any other class. What changes between classes is the scope of protection — class 11 covers iluminación y climatización, and if you operate in other areas you should evaluate whether you also need to register in additional classes.
- 1Prior art search. We verify whether an identical or similar trademark is already registered in class 11 or related classes. This search is what makes the difference between the national average approval rate of 53% and our 88%.
- 2File preparation. We draft the description of the specific goods or services within class 11 to maximize protection and minimize the risk of objections.
- 3Application and publication. We file the electronic application with INAPI and manage publication in the Official Gazette.
- 4Defense against oppositions and objections. We respond to any third-party oppositions and examiner objections, at no additional cost.
- 5Final fee payment and certification. Once the trademark is approved, we pay the grant fee and obtain the registration certificate in your name, valid for 10 years.

Registering only one class when you operate in several
If your business mixes products from class 11 with activities in other classes (e.g., retail in class 35 or software in class 42), protecting only one class leaves your trademark exposed in the others. We help you define the optimal portfolio based on your actual business model.
Confusing the Nice class with the SII tax activity code
Nice classes are a trademark classification system, not a tax category system. A company with a single tax activity code may need several Nice classes, or vice versa.
Describing goods or services too broadly or too vaguely
The description within class 11 must be specific to avoid conflicting with existing trademarks or receiving examiner objections. Poor wording can delay the process or lead to avoidable oppositions.
