Trademark Class 40: Material Treatment

Key service categories include custom manufacturing and assembly to order, metalworking, woodworking, textile treatment (dyeing, finishing, and printing on fabrics), food and beverage processing, water treatment, waste treatment and recycling, and energy generation. Top filing firms include LZ Legal Services, Greenberg Traurig, and Taft Stettinius & Hollister, the latter reflecting the class's concentration in manufacturing-heavy regions. The growing importance of sustainability and circular economy practices has increased filing activity for recycling, upcycling, and waste-to-energy conversion services.

The defining classification principle in Class 40 is the distinction between manufacturing goods for sale (classified in the relevant goods class) and providing custom manufacturing or material treatment as a service to others. A company that produces and sells printed t-shirts files in Class 25 for the goods, but a company that provides custom printing services on customer-supplied garments files in Class 40. Similarly, a brewery selling its own beer files in Class 32, but contract brewing services belong in Class 40. This goods-versus-services distinction is the single most common source of classification errors in this class. 3D printing services, a rapidly growing subcategory, belong in Class 40 when offered as a service.

Strategic multi-class filings commonly pair Class 40 with Class 37 for installation services that follow custom manufacturing, Class 42 for the design and engineering services that precede manufacturing, and the appropriate goods class for any finished products sold under the same brand. Sustainability-focused brands should consider Class 40 for recycling and treatment services alongside Class 35 for environmental consulting and Class 42 for environmental monitoring technology.
