Class 37 is the class of getting things built and fixed: it covers construction, repair and installation, from house building and electrical work to the car repair shop. The EUIPO register holds 175,093 trademarks in Class 37, of which 100,995 are registered (as of July 2026, EUIPO register data). The class is growing strongly: new registrations climbed from 7,448 in 2020 to 9,378 in 2024, a 26 percent increase, with another 8,780 added in 2025. The list of top filers holds a surprise: it is not construction groups that lead the class, but car makers. Volkswagen sits at the top with 717 trademarks, followed by Deutsche Telekom (474), Jaguar Land Rover (164), IBM (147) and Mercedes-Benz (138). The reason: repair and maintenance are services, and services of this kind belong in Class 37, from workshop servicing to network installation. 48 percent of trademarks in Class 37 are word marks, with the rest mostly split between logos and combined word and figurative marks.
What belongs in Class 37?
Class 37 covers three areas: building construction, repair work and installation services. It is always about the hands-on or technical execution as a service. Typical examples: building and civil engineering, renovation and refurbishment, trades such as electricians, plumbing and heating installers, painters and roofers, plus car repair shops, building cleaning and the maintenance of machines and equipment. One important distinction: building materials themselves belong in goods classes, such as Class 19 for construction materials or Class 6 for metal components. And if you design rather than build, Class 42 is the right place, because architecture and engineering services do not fall under Class 37.

Often combined with
When in doubt, do not file Class 37 in isolation: in practice it is most often combined with Class 42 (planning, engineering and architecture services), Class 35 (advertising, brokerage, franchising) and Class 9 (software, controls, smart devices). Think before filing about where your business is headed, because the list of goods and services cannot be extended later. Describe your services in concrete terms too, for example installation of photovoltaic systems rather than just construction, which makes the protection more robust. And search the register first: Class 37 is home to some very active filers, including Volkswagen, Deutsche Telekom and IBM, and nobody wants to collide with them.
Common mistakes with Class 37
The most common mistake around Class 37 is mixing up planning and execution. A construction firm that also offers design and structural engineering needs Class 42 alongside Class 37, and a pure planning office cannot rely on 42 alone once it starts building itself. Second mistake: forgetting the service side. If you sell products and offer assembly, maintenance or repair under your own brand, you need Class 37 on top of your goods classes. That is exactly why Volkswagen and Mercedes-Benz secure the class for their workshop and service business. Third, many founders underestimate how digital their offer becomes: a trade services app or smart building technology touches Class 9, which is often missing from the initial filing.

Frequently Asked Questions
What belongs in Nice Class 37?
Class 37 covers construction, repair and installation: building and civil engineering, renovation, trade services such as electrical, plumbing, painting and roofing work, plus car repair shops, building cleaning and machine maintenance. It protects the execution as a service. Building materials belong in goods classes such as 19 or 6 instead, and planning services in Class 42.
Why do car makers lead Class 37?
According to EUIPO register data (as of July 2026), Volkswagen is the biggest filer in Class 37 with 717 trademarks, and Jaguar Land Rover (164) and Mercedes-Benz (138) also make the top five, alongside Deutsche Telekom (474) and IBM (147). The reason: repair and maintenance are Class 37 services, so manufacturers use the class to protect their brands for workshop servicing, parts business and installation services.
As a trade business, do I need Class 37 or Class 42?
For execution, meaning building, installing and repairing, Class 37 is the right one. Class 42 covers planning, engineering and architecture services instead. Many businesses do both, for example an electrical firm that designs and installs systems, and they are safest with the combination of 37 and 42.
Which classes are typically combined with Class 37?
Most often Class 42 for planning and engineering services, Class 35 for advertising, brokerage and franchising, and Class 9 for software and smart device technology. An installation business with its own service app and franchise ambitions covers the typical gaps with 37, 9 and 35.
