First-to-file in China: why you should register before you enter the market

China grants trademark and patent rights to the first applicant. Here is what that means for foreign companies and when to file.

In most countries, using a brand creates rights. In China, filing does. This single difference explains most of the IP disputes that foreign companies face after entering the market.

What first-to-file means

For trademarks, rights generally go to the first applicant, with limited exceptions such as well-known marks and certain prior rights. For patents, the first applicant to file wins, and a public disclosure before filing can destroy novelty. China does have a grace period for some disclosures, but it is narrow, so do not plan around it.

When to file

  • Trademarks: before sample orders, trade fairs or product announcements. Paris priority lasts six months from your first trademark filing.
  • Patents: before any publication, sale or exhibition. Paris priority lasts twelve months from your first patent filing.
  • Copyright: register key artwork and software early, because it gives you evidence of ownership.

Do not forget the Chinese name

Many customers know your brand by a Chinese name, whether you chose one or not. Choosing, clearing and registering it early prevents someone else from defining your brand for local customers.
