Handling a dispute or opposition: don’t endure, act fast

   En Chine, le système de marques repose sur le principe du premier dépôt. Cela entraîne des conflits fréquents, parfois malveillants. Dès qu’un tiers dépose une marque similaire ou identique à la vôtre, ou vous bloque volontairement, vous avez un délai limité pour réagir. Passé ce délai, le silence vaut acceptation.

Qu’il s’agisse d’une opposition à une marque déposée par un tiers ou d’une action contre un squatteur, chaque jour compte.

 Lorsqu’une marque est déposée en Chine, elle est publiée dans le bulletin officiel CNIPA pour une période d’opposition de 3 mois. Durant cette période, toute personne justifiant d’un intérêt peut déposer une opposition auprès du CNIPA.

Deadline:

  • 90 calendar days from the publication date.

  • After this period, you lose your right to oppose.

Requirements:

  • You must prove that you own an earlier trademark (registered or well-known).

  • It is also possible to argue the applicant’s bad faith, especially if you had prior commercial relationships or if the trademark targets a related sector.

Possible outcome:

  • Total rejection of the opposing trademark.

  • Favorable decision within 9 to 12 months.

Our commitment: handle your case urgently

   When it comes to trademarks in China, inaction is fatal. The rules are strict, deadlines are short, and mistakes are irreversible. Many companies realize too late that a similar trademark has been approved, or that their silence led to automatic validation.

Without local advice and understanding of the Chinese legal framework, your arguments may be misunderstood, rejected, or simply ignored.
Our team acts quickly, in Chinese, following required formats, with a strategy tailored to your situation.

Deadline:

  • No strict deadline to invalidate, except in particular cases

  • For cancellation for non-use: possible from the 3rd year following registration.

Documents to provide:

  • Evidence of your priority: filing, public use in China, reputation.

  • Certified translations (if applicable).

  • Possibly: evidence of bad faith of the applicant.

Procedure duration:

  • On average 12 to 18 months for a decision.
