For small businesses looking to avoid agency fees, AI image generators can produce dozens of logo concepts in a single afternoon. What they cannot provide is legal peace of mind. Spanish and EU trademark law do not require a logo to be drawn by a human, so an AI-assisted design can indeed be filed as a trademark. However, registration by the office does not guarantee freedom from conflict with earlier marks, and a logo created solely by a machine may lack copyright protection. This guide outlines what to check before you print business cards.
- AI is great for exploring visual identity ideas but dangerous as the final word. Use it to brainstorm, not to finalize.
- Trademark offices do not proactively check for similarity to earlier marks. Conflicts only surface if the owner of a prior mark files an opposition.
- Copyright protection is doubtful for purely AI-generated logos. Without human creative input, you may have no authorial rights, making trademark registration even more critical.
What AI Tools Allow Today
Modern AI tools let you generate variants, adapt formats, and maintain a consistent aesthetic across all brand assets. A European example is Magnific, the current name of Freepik, the Malaga-based company. The platform bundles image, video, and audio generation models and allows you to upload a brand manual and references so the output respects your colors and style. It also includes a library of more than 250 million photos, vectors, icons, and templates licensed for commercial use.
Pay attention to the fine print: Magnific’s terms of use prohibit using its stock content, in whole or in part, in a trademark, unless you modify it into something new and distinct that cannot be confused with the original, or use it solely as a template or test. In plain terms: a retouched stock icon is not a good foundation for your logo.
Can You Register an AI-Made Logo as a Trademark?
Yes, you can apply, because neither Spanish nor EU law asks who drew the sign. What they require is that it serves to distinguish your goods or services and can be represented clearly.
Spain’s Law 17/2001 on Trademarks, in Article 4, states that “all signs” can be trademarks, including drawings, letters, numerals, or colors, provided those two conditions are met. The EU Regulation 2017/1001, which governs EU trademarks before the EUIPO, uses the same formula in Article 4 and clarifies in Article 5 that the proprietor may be a natural or legal person. Neither mentions authorship or AI.
Grounds for refusal lie elsewhere. Article 5 of the Spanish law prohibits registering signs that lack distinctive character, are descriptive, or are deceptive. Here AI has its own weakness: it tends toward the generic. A steaming cup for a café is exactly the kind of image that is hard to defend as distinctive.
Registration grants, under Article 34, an exclusive right to prevent others from using an identical or similar sign where there is a likelihood of confusion, and lasts ten years, renewable, according to Article 31.
Why the Office Won’t Warn You About Similar Marks
Because neither the OEPM nor the EUIPO examines your logo against earlier marks ex officio. That conflict is resolved only if the owner of the other mark files an opposition.
Article 20 of the Spanish law is clear: the OEPM examines on its own the absolute prohibitions of Article 5 and a specific letter of Article 9.1. Earlier marks under Article 6, or signs reproducing works protected by copyright under Article 9.1.c, are discussed only if someone files an opposition. The same happens at the EUIPO: Article 8 of the EU regulation denies registration for earlier marks “where there is an opposition by the proprietor,” and Article 60 allows subsequent invalidity requests based on an earlier copyright.
The practical consequence is uncomfortable: you can have your logo registered and still receive a claim. In November 2024, the Benelux trademark office rejected, for Class 16 goods (paper, cardboard, and printed matter, among others), a logo featuring a stylized penguin and the word “ARTPENGUIN,” following an opposition by Penguin Books. According to the European Commission’s IP Helpdesk summary, the applicant defended itself with arguments drafted by ChatGPT claiming its modern design was distinct from the publisher’s classic one. The office concluded that sharing the same animal as the central element and the word “PENGUIN” weighed more than that stylistic difference.
The same summary covers another case from that month: the EU General Court annulled an EUIPO decision that had rejected Giorgio Armani‘s opposition against a sign of horizontal lines. It held that no global assessment of the likelihood of confusion with the fashion house’s stylized eagle had been made, which it considered visually similar, because the consumer perceives marks as a whole and not detail by detail. My reading: “I made it different” is not an argument if the overall impression recalls another brand, and an image generator, by definition, resembles what it has seen.
How to Check Your Logo Before Filing
Five steps that do not replace a professional if your business depends on the mark:
- Search official databases. The OEPM has a trademark and trade name search tool. For the EU, the EUIPO launched Early TM Screening in November 2025, an AI-powered tool that detects potential conflicts with earlier marks via TMview and flags distinctiveness issues. The EUIPO itself warns that results are informative and not exhaustive.
- Run a reverse image search. If your logo appears nearly identical on other websites, better to know now.
- Do not ask for “in the style of” a brand. Requesting an AI logo “like” a well-known company is manufacturing the problem from the previous step.
- Retouch and simplify by hand. The more you intervene in the final design, the more it is yours and the less generic it becomes.
- Keep a trail. Prompts, versions, and dates.
What About Copyright in the Logo?
Here AI works against you. Spain’s Intellectual Property Law states in Article 5 that an author is “the natural person who creates” the work. If the logo comes straight out of a machine, without a recognizable creative contribution from you, it is doubtful that you hold copyright over it.
That makes trademark registration even more important: if you cannot rely on copyright to stop someone from copying your logo, registration is what you have left.
My position is pragmatic. Using AI for the logo of a bakery or a consultancy makes perfect sense, and the law does not prevent it. What does not make sense is skipping the search for earlier marks because the design “was made by the machine.” The responsibility for ensuring it does not resemble another brand is not the generator’s—it is yours, and the office will not do that work for you until someone files an opposition.
