REKEL PATENT / Guide to IP matters

Opposition, invalidity and loss of protection

A conflict can arise during examination of somebody else’s application or after a right has been granted. Opposing a trade mark application, opposing a granted patent, seeking invalidity and seeking a declaration of loss of protection serve different purposes. The appropriate procedure depends on the right, dates and legal ground. A general belief that a competitor should not hold a registration is insufficient.

Competent authority

UPRP under the applicable Polish procedure; EUIPO for EU trade marks and designs; EPO for opposition to a European patent. Each system has separate rules.

Scope and context

Rekel Patent is an information website published by Vadym Rekel. Its materials explain intellectual-property procedures and the work of qualified patent attorneys. Sources verified on 16 October 2026. Current legislation, documents, service dates and applicable procedural instructions matter in an individual case.

Stages of the procedure

  1. 01

    Identify the right and available remedy

    Check the registration or application number, owner, territory, publication date and procedural status. Distinguish objections concerning eligibility for protection, conflicts with earlier rights and later non-use or other grounds for loss of protection. Those distinctions affect standing, time limits and the relief that can be requested.

  2. 02

    Grounds and supporting evidence

    A trade mark dispute may require earlier-right documents, comparisons of signs and goods, and evidence of genuine use. Patent disputes may turn on prior-art documents, reliable publication dates and their relationship to the claims. Design disputes require analysis of earlier disclosures and the overall impression within the relevant legal framework.

  3. 03

    Exchanging submissions and considering settlement

    Submissions must address the specific legal ground rather than merely criticising a competitor’s business. Rules on allegations and evidence must be followed, and procedural directions answered. Limiting a specification, agreeing coexistence or withdrawing a request requires consideration of consequences beyond the immediate proceedings.

  4. 04

    Decision and further steps

    The outcome may affect all or part of the right or specification. Its effect over time and its interaction with parallel infringement proceedings need separate examination. Review mechanisms follow the particular procedure. Polish contentious proceedings should not be confused with trade mark opposition or assumed to operate identically to EUIPO proceedings.

Risks and decision points

  • Choosing the wrong remedy or missing a time limit may close that procedural route.
  • Standing differs between grounds and must be checked; not every applicant can invoke every objection.
  • Late evidence or materials without a reliable date may fail to support the challenge.
