China Trademark Classes for Software & SaaS Companies: Class 9, Class 42 & China Filing Strategy

Why Software Trademark Filing Is Different From Product Brands

Software companies face three structural challenges that hardware, food, and fashion brands do not:

Why CNIPA Subclasses Matter (USPTO vs CNIPA)

Unlike the USPTO or EUIPO, CNIPA further divides each class into multiple subclasses (similar goods groups). For software companies, this means two marks can coexist in different subclasses even within the same class — a concept that surprises most foreign applicants. For a detailed explanation, refer to our guide: What is the China Trademark Subclass System?

For instance, within Class 9:

• 0901 – Computer software (downloadable programs, operating systems)
• 0907 – Communication software (messaging apps, video conferencing)
• 0908 – Audio and video software (media players, streaming apps)

A registration in subclass 0901 for “computer software” does not automatically block a later application in subclass 0907 for “communication software.” In practice, we have seen cases where a US company registered its collaboration app in 0901, only to discover a Chinese competitor later registered the same brand in 0907 for a messaging tool — and the CNIPA examiner found no conflict because the subclasses were different. This is one of the most common and costly surprises for foreign software companies, and it underscores why subclass‑level mapping must be part of any China filing strategy from day one. Learn how to select the right subclasses in our article How to Correctly Select China Trademark Classification Subclasses.

1. Core Classes for Software & SaaS Companies

Class 9 – Downloadable Software, Mobile Apps, AI Applications

Class 9 covers downloadable software: mobile applications, computer programs, operating systems, AI software, and any software that is installed on a device. If your product is distributed through an app store or as a downloadable installer, Class 9 is the primary class. However, as noted above, the subclass mapping within Class 9 is critical. For a complete list of CNIPA‑approved goods and services items across all classes, see the Similar Goods & Services List, and for subclass‑specific PDFs you can explore each class (e.g., Class 09 subclasses).

Class 42 – SaaS, PaaS, Cloud Computing, Software Development

Class 42 is the home for software‑as‑a‑service, platform‑as‑a‑service, cloud computing, data storage, hosting services, and software development. If users access your software through a browser without downloading anything, or if you provide API‑based services, cloud infrastructure, or custom software development, Class 42 is essential. A Class 9 registration does not protect a SaaS platform, and a Class 42 registration does not protect a downloadable app.

Class 35 – Online Marketplaces, Subscription Platform Marketing

Class 35 covers online retail services, subscription platform marketing, and business management. If your software operates a marketplace or if you plan to market a subscription service directly to Chinese consumers, Class 35 provides the commercial service layer that Class 9 and Class 42 do not cover.

Class 38 – Communication Platforms, Messaging, Video Conferencing

Class 38 covers data transmission, streaming, messaging services, and video conferencing. For platforms with communication features — like a project management tool with built‑in chat — Class 38 may be required in addition to Class 9 and Class 42.

CNIPA Standard Items for Software (Typical Selections)

Below are commonly used CNIPA-approved goods and services items. Using these precise descriptions helps avoid rejection and ensures the correct subclass coverage.

Using these standard CNIPA items — rather than free-text descriptions — significantly reduces the risk of office actions and ensures your application maps to the correct subclass on the first examination.

2. The Class 9 vs Class 42 Problem — Core Analysis

CNIPA draws a bright line between software as a product (Class 9) and software as a service (Class 42). The following table illustrates how the same functional product can require different class protection depending on how it is delivered:

CNIPA examiners ask: “Is the software downloaded and installed, or accessed as a service?” The answer determines whether protection falls under Class 9, Class 42, or both — and filing in the wrong class leaves the core business model unprotected. This is a direct consequence of China’s first‑to‑file principle, where the timing and accuracy of your filing determine ownership.

3. Software Ecosystem Coverage Examples

Each column in the table above represents a separate CNIPA examination unit. A trademark registered only in Class 9 for a video conferencing platform does not protect the cloud meeting service (Class 42) or the streaming functionality (Class 38).

5. Common Filing Mistakes Software Companies Make

• Filing only in Class 9 — believing “software” covers both downloadable and cloud‑based products.
• Filing only in Class 42 — protects the SaaS platform but leaves the downloadable app unprotected.
• Filing only the English brand name — Chinese users create a Chinese name; if unregistered, a third party will claim it.
• Not covering AI‑specific services — AI SaaS requires explicit subclass entries in Class 42.
• Overlooking Class 38 for communication features — messaging and streaming need separate protection.
• Assuming a Madrid Protocol registration covers China — specification must satisfy CNIPA subclass requirements.
• Filing after app store launch — public exposure triggers squatting; file first.

6. Filing Strategy by Business Type

7. Chinese Brand Name Strategy for Software

In China’s software market, Chinese brand names are how users search, share, and discuss products. Platforms like Zoom (中：中目), Microsoft Teams (中：微软 Teams), and Feishu (飞书) all operate under distinct Chinese names. If you do not create and register a Chinese trademark, one of three things happens: Chinese users coin a name organically, a local partner registers it, or a competitor registers it to block you. In all scenarios, the foreign software company loses control of its own brand identity in China. Register a Chinese version early — a phonetic transliteration, a meaningful equivalent, or both — and file it in all core classes simultaneously with your English‑language mark.

10. Conclusion & Strategy Review

For software and SaaS companies, China trademark protection is a classification challenge that rewards precision. The line between Class 9 (downloadable software) and Class 42 (cloud‑based services) is the single most important distinction — and CNIPA’s subclass system adds another layer of complexity that does not exist in the USPTO or EUIPO. Multi‑component software platforms must be mapped as an ecosystem, not as a single filing.
