Unauthorized alteration of a registered trademark refers to a registrant's act of, in the course of using a registered trademark, changing the approved registered representation without going through statutory procedures, to a degree that affects the trademark's distinctive character. Article 49(1) of the Trademark Law lists it as an illegal act.
Legal Consequences
- The local market regulation authority orders rectification within a time limit;
- If rectification is not made by the deadline, the CNIPA cancels the registered trademark;
- The altered mark is not protected by the exclusive right in the registered trademark (Article 56: the exclusive right is limited to the trademark as approved for registration);
- Placing the registration mark (®) on the altered mark additionally constitutes passing off an unregistered trademark as registered under Article 52.
What Degree of Change Counts as "Unauthorized Alteration"
The test is whether the change affects the trademark's distinctive character and whether the relevant public would regard it as a different trademark:
Usually not deemed an alteration (reasonable variations of the same trademark): equivalent substitution among common typefaces, horizontal/vertical typesetting adjustments, proportional scaling, and color changes of a black-and-white registration. Usually deemed an alteration: adding or deleting textual or graphic elements; a highly artistic font that makes the text hard to read; changing the main structure of a device; changing the relative positional relationship among the elements of a combination trademark; traditional/simplified character switching that creates reading differences.
The Linked Risk in Non-Use Cancellation Proceedings
If only the altered mark is used over a long period, in a non-use cancellation defense the trademark shown on the evidence may differ too much from the registered representation, and the examiner may find that it does not constitute use of the registered trademark — the trademark faces cancellation all the same. In other words, non-compliant use plants two mines at once: "administrative penalty under Article 49" and "non-use cancellation."
The Difference from a Lawful Change Filing
When the registrant's name, address, or similar particulars change, the proper step is a trademark change filing; the trademark representation itself cannot legally be "changed" — a new representation can only be obtained through a fresh registration application. This is a cognitive blind spot for many companies: the correct path for a logo change is a new application, not shielding a new mark with an old certificate.
Compliance Recommendations
- When a brand upgrade introduces a new mark, file a new trademark application in parallel;
- During the transition between old and new marks, keep the old trademark in compliant use to maintain its validity;
- Internally establish the red line that "only the certificate representation may carry the registration mark (®)";
- Establish an approval process for trademark representation use, checking marketing materials against the registration certificate before release.
