One Trademark Isn't Enough: Take Classes 35, 42, and 41 Together
Trademarks split goods and services into 45 classes—you’re protected only in the class you register. Plenty of people register one class and call it done, then discover promotion itself sits in another class. This lesson covers the classes that matter most for internet products, plus the invisible trap of specimen consistency.
Advertising · business management
Covers advertising, promoting goods for others, business management. Whatever you build, if it involves promotion and commercial monetization, you can’t skip this class. It’s the ticket for every later marketing move—must have.
Software services · internet tech
Software design and development, SaaS, platform tech services live here. Software, platforms, online tools—must file. If your product delivers as an online service, this is the main battlefield.
Education · training · entertainment
Courses, content, exhibitions, community events. The turf for knowledge commerce and content monetization. Product people often ship courses on the side—file this class in parallel.
Easy to miss: Class 9. Downloadable software and Apps count as “goods” and sit in Class 9. So full coverage for an App product is usually 9 + 42 + 35, plus 41 if you have courses. Current Trademark Law lets one application tick multiple classes—file them together.
Look back at that three-year non-use cancellation case from Lesson 4: the blocking prior trademark was registered in Class 35. Why everyone piles into 35—because nobody can skip it. That’s also why Class 35 is the favorite hunting ground for trademark squatters.
Check the businesses you’re in or plan to enter; the suggested registration classes update live below. Multi-select is fine.
Check at least one business first.
This list is a starter reference. Before filing, pick line items against the Classification of Similar Goods and Services on the China Trademark Website.
Picking the right classes is only step one. Another invisible trap: the trademark specimen you register and the one you actually use must clearly correspond. Register a black-and-white word mark, then use a redesigned color irregular graphic—they don’t match, and trouble follows.
Match: enforcement holds
Registered and used specimens clearly correspond; when someone copies you, the evidence chain is clean. If someone files three-year non-use cancellation against you, ordinary business records are evidence of use—ready to hand over.
Drift: you hand them the knife
Use differs from registration; they can argue the registered mark has “no actual use,” and you may have no matching evidence for non-use cancellation; in enforcement they can weaponize the drift too. When you rebrand visuals, file the new specimen in parallel.
Lesson 4 covered how the burden of proof in three-year non-use cancellation sits with the registrant. Read that lesson with this one: non-use cancellation is a double-edged sword—you can use it to clear others, and others can use it to clear you. Specimen match plus kept evidence of use is your defense.
We ourselves registered Chinese, English, logo, and related variants for one brand—a row of a dozen-plus marks. Not showing off spend; it’s what you do after Lesson 4’s two near marks taught you a lesson.
- Beyond the main mark, lock common variants: add-a-character, homophones, English spellings.
- Tight budget: protect “main mark × core classes” first; backfill variants when cash allows.
- Set a yearly calendar reminder—check renewal deadlines and whether new businesses need more classes.
Some agents push “register all 45 classes.” Sounds safe; most OPCs don’t need it.
- All-class cost is over ten times three or four core classes—and unused classes can still draw three-year non-use cancellation.
- Test: will this class actually generate business within three years? Yes → file; no → leave the money for the product.
- You can file yourself on the China Trademark Website—the process isn’t mystical. Agents earn their keep on line-item selection and monitoring, not “filling the form for you.”
Everyone needs Class 35. Promotion and commercial monetization can’t skip it—and that’s why squatters love it most.
App products’ standard kit is 9 + 42 + 35. Add 41 for courses. One application can tick multiple classes.
Registered specimen must match used specimen. When you rebrand, register the new specimen; keep the old one.
Defensive registration locks common variants. Add-a-character, homophones, reversals, English spellings—grab what others would think of first.
Basis: Trademark classification follows the International Classification of Goods and Services for the Purposes of the Registration of Marks (Nice Classification), adopted by China since 1988; classes and line items follow the Classification of Similar Goods and Services published on the China Trademark Website; registration and use rules—Trademark Law (2019 Amendment); the Trademark Law revised June 2026 takes effect January 1, 2027.
