Trademark applications and registrations in Class 37 over the past 15 years.
Class 37 covers building construction, repair, and installation services. With approximately 102,500 live marks, it is a moderately filed service class that serves the construction, maintenance, home improvement, automotive repair, and equipment installation industries. The class captures the full lifecycle of built infrastructure — from new construction through ongoing maintenance to eventual renovation.
Key service categories include general building construction, residential and commercial remodeling, plumbing, electrical installation, HVAC installation and repair, painting, roofing, and cleaning of buildings. Automotive repair and maintenance services are also firmly within Class 37, as are installation services for machinery and equipment. Top filing firms include LZ Legal Services, Greenberg Traurig, and LegalForce RAPC, with filing volume driven by both national service chains and the large number of regional contractors and franchise operations seeking trademark protection.
Classification boundaries in Class 37 frequently cause confusion. The core distinction is between installation or repair (Class 37) and the manufactured goods being installed (classified by product type in the appropriate goods class). A company that manufactures and sells plumbing fixtures files in Class 11, but the plumbing installation service belongs in Class 37. Cleaning of buildings and structures is here, but cleaning of clothing belongs in Class 37 only if it involves dry cleaning or laundering services — personal cleaning products are goods in Class 3. Pest control and fumigation services belong in Class 37, not Class 44. Mining and drilling services, despite their industrial nature, also fall within this class.
Strategic multi-class filings commonly pair Class 37 with Class 42 for architectural and engineering design services that precede construction, Class 40 for custom manufacturing and material treatment services, and Class 36 for real estate development companies that both build and sell properties. Franchise operations in home services should file Class 37 for the underlying repair and maintenance services alongside Class 35 for the franchise business model itself.
Class 37 includes mainly services rendered by contractors or subcontractors in the construction or making of permanent buildings, as well as services rendered by persons or organizations engaged in the restoration of objects to their original condition or in their preservation without altering their physical or chemical properties.
