Overview of Class 7
Trademark Class 7 is the primary international classification for machines, machine tools, power-operated tools, motors and engines (except for land vehicles), machine coupling and transmission components (except for land vehicles), agricultural implements other than hand-operated, and incubators for eggs.
Registering in Class 7 is a cornerstone for the manufacturing, construction, and engineering sectors. This class protects the brand identity of everything from massive industrial lathes and bulldozers to household electric blenders and 3D printers. In India’s "Make in India" era, a Class 7 trademark ensures that your mechanical innovations and hardware brand names are legally shielded from copycats, providing the trust required for B2B contracts and industrial supply chains.
What is included?
- •Industrial Machinery: Lathes, milling machines, cranes, and bulldozers
- •Power Tools: Electric drills, welding machines, and high-pressure washers
- •3D Printing: Industrial 3D printers and additive manufacturing machines
- •Robotics: Industrial robots and automated handling machines
- •Engines & Motors: Motors for boats, aeronautical engines, and generators
- •Cleaning Gear: Vacuum cleaners, floor polishers, and steam cleaners
- •Agriculture: Tractors, combine harvesters, and mechanical sowers
- •Specialty: Automatic vending machines and incubators for eggs
What is excluded?
- •Motors and engines for land vehicles (Class 12)
- •Hand-operated tools and implements (Class 8)
- •Surgical and medical machines (Class 10)
- •Repair and maintenance of machinery (Class 37)
- •Rental of machines and equipment (Class 35, 37, or 40)
- •Electronic and scientific software (Class 9)
- •Safety gear and protection apparatus (Class 9)
Powering the Industrial Brand
Class 7 is the engine room of intellectual property. In the machinery sector, where brand reputation is tied to safety and precision, a trademark is your most valuable asset. It distinguishes your high-performance equipment from generic alternatives.
The Vehicle Rule: A common pitfall is trying to register land vehicle engines in Class 7. While boat and airplane engines are Class 7, anything that powers a car or motorcycle belongs in Class 12. Correct classification is essential for an enforceable trademark.
India’s infrastructure boom makes Class 7 one of the most active classes for trademark litigation. Protecting your brand here prevents competitors from using similar names on construction or industrial gear that could compromise project integrity.

Registration & Objection Handling
- 1. Functional Search: Conduct a thorough search in Class 7 and Class 12 (Vehicles) to ensure no conflict with automotive giants.
- 2. Descriptiveness: Avoid generic names like "FAST MACHINE" or "HEAVY CRANE". The Registrar will reject these under Section 9.
- 3. Multi-Class Strategy: If you manufacture machines (Class 7) and also provide maintenance (Class 37), file in both classes.
- 4. Detailed Goods List: Specify the exact type of machine (e.g., "Rotary drilling machines for mining") rather than just "Industrial machines".
- 5. Evidence of Use: For established manufacturers, providing photos of the trademark permanently embossed on metal machines is powerful "Proof of Use".
