Class 35: Why Every Brand Should File Defensively in China

28 7 月, 2026 | By ctms

Class 35 in the Nice Classification covers “advertising, business management, business administration, office functions.” It is widely regarded as the most important defensive class for brand owners in China.

Why Class 35 Matters

Trademark squatters in China frequently file in Class 35 for well-known brand names. If your brand is registered in Classes 9, 25, or 42 but not in Class 35, a squatter can register your brand name in Class 35 and offer “retail services” or “advertising” using your brand – actions that can confuse consumers and dilute your brand value.

What’s Covered in Class 35

  • Advertising services of all kinds
  • Business management and administration
  • Retail and wholesale services
  • Online marketplace services
  • Import-export agency services

We recommend including Class 35 in your China trademark strategy, especially if your brand has recognition in international markets.
