When facing a trademark invalidation action, what’s your first reaction? Many businesses instinctively respond by gathering and submitting all available evidence of use: contracts, invoices, product photos, marketing materials.
It feels like the right move, but it actually carries significant strategic risks.
In cases of trademark invalidation, "actively providing evidence" does not necessarily mean "providing favorable evidence".
Invalidation is not a fill-in-the-blanks exercise — it’s a targeted offensive.
Trademark invalidation is not a one-size-fits-all process. The grounds for invalidation matter, and your response should be tailored accordingly.
In China, invalidation actions are typically based on:
absolute grounds (e.g. lack of distinctiveness, deceptive, etc), or
relative grounds (most commonly, similarity with prior trademarks)
In practice, many cases rely on similarity arguments. That means the core issue is not whether you used the mark, but whether your mark is confusingly similar to another.
When Evidence Becomes a Liability
Not All Evidence is Helpful
“More evidence is better.” This is a dangerous misconception. In reality, in trademark review practice, examiners prioritize relevance, authenticity, and probative value over quantity.
Certain types of materials are especially problematic:
Evidence that lacks clear linkage to the trademark (for example, invoices without the mark, or product images without supporting documentation)
Internally generated marketing materials that cannot be independently verified
Suspicious or inconsistent sales data, particularly from online stores with scattered or minimal activity
Evidence sets that appear artificially perfect or overly synchronized, raising credibility concerns
Reviewing authorities are experienced in identifying inconsistencies and patterns that do not reflect normal commercial practice.
Strategy first, Evidence second
A Practical Reminder
Trademark disputes are often part of a broader enforcement strategy.
An invalidation action may be a precursor to litigation. What you submit today could shape the evidence landscape tomorrow.
For that reason, responding mechanically or over-disclosing information can carry real legal and commercial risks.
