What class 37 covers
The Nice Classification groups every product and service into 45 classes; class 37 is Construction, repair, installation services. When a rights owner files a mark, they choose the classes they sell in — and that is where the mark protects them. Two identical names can coexist in different classes; the same name in the same class is the pattern behind most takedowns.
How crowded class 37 is
Across the registers we hold, 2 130 790 marks list class 37, and 1 042 621 of them are live (registered or pending). The more crowded the class, the higher the chance that a name you like already belongs to someone selling what you sell — which is exactly why we check the class, not just the spelling.
Before you file or publish
Check your name against class 37 first, then against the neighbouring classes your buyers might also search. If the closest marks are dead or sit in unrelated goods, your risk is lower; if a live mark in class 37 sounds like yours, review it before you print, list or file. TMAtlas Risk Score is a prioritisation signal, not a legal opinion.
Do I need to register in class 37 to sell my product?
No registration is needed to sell. But if someone else holds a live mark in class 37 that looks or sounds like your name, they can ask the marketplace to remove your listing. Checking first is free; a takedown is not.
My name is taken in class 37 but free in another class — can I use it?
Often yes, if the goods are genuinely different and buyers would not confuse them. Marketplaces, however, react to the complaint, not to the nuance. Review the live mark, its goods list and its territory before you decide.
Which registers do you search for class 37?
All 85 registers we hold — 54.2 million records — filtered by the territories you sell in. Every result shows which registers were searched and which are validated record by record.
