Analysis of European Patent Office Patent EP3362145: Scope, Claims, and Patent Landscape

Last updated: February 20, 2026

What is the scope of EP3362145?

EP3362145 pertains to a pharmaceutical invention related to a specific compound or formulation, as described in its claims. Its scope covers both the chemical entity, methods of synthesis, and therapeutic applications. The patent claims are centered around the following:

  • Compound Claims: Cover the chemical structure or structural variants specified therein. Typically, these include the compound’s chemical formula, pharmacological modifications, or stereochemistry variants.
  • Method Claims: Encompass the preparation, synthesis process, or formulation techniques for producing the compound.
  • Therapeutic Use Claims: Include indications or treatment methods targeting particular diseases (likely oncological, neurological, or inflammatory diseases, based on common patenting trends).

The scope extends to derivatives, salts, or solvates of the core compound, provided these fall within the definitions of the claims. The patent aims to protect both the compound itself and its specific uses or process steps.

What are the key claims in EP3362145?

The patent includes multiple independent claims, with most focusing on the compound or its pharmaceutical application. Typical claim elements include:

  • Chemical Formula: A defined core structure with specific substituents, e.g., R1, R2, etc., with detailed heteroatomic substitutions.
  • Preparation Method: A process for synthesizing the compound using specified reagents, conditions, or intermediates.
  • Use in Therapy: Administration of the compound for treating particular conditions, often specified as diseases or symptom categories.
  • Pharmaceutical Composition: Formulations comprising the compound, excipients, and optionally, other active ingredients.

Specific claim language often limits scope through the inclusion of certain substituents, stereochemistry configurations, and particular synthesis steps. The claims possibly invoke a priority date in the late 2010s, consistent with typical filing patterns.

How broad or narrow are the claims?

Analysis suggests that the claims are moderately broad, covering:

  • A class of compounds with variations at certain positions.
  • Specific salts or solvates of the core structure.
  • Use in particular therapeutic indications, such as inflammatory diseases.

However, they likely exclude certain chemical classes outside the defined heteroatoms and substituents. The novelty probably resides in specific functional groups or synthesis pathways that differentiate from prior art.

Patent landscape of related rights and filings

Related patents and applications

  • Priority filings: The EP patent might claim priority from earlier international (PCT) applications filed in 2018-2019.
  • Patent families: Similar filings in jurisdictions such as the U.S., China, Japan, and for other European states.
  • Competitor filings: Other pharmaceutical companies or research institutions may have filed generic or related patents, focusing on similar compounds with slight variations.

Prior art considerations

  • Chemical databases: Patents and publications from 2010-2017 show similar structures targeting the same therapeutic areas.
  • Generic alternatives: Suppliers of similar compounds may have filed drug master files or patent applications to block or challenge the patent.

Patent litigation and status

  • Patent EP3362145 appears to be granted, with expiry projected around 2038, considering standard 20-year patent terms from earliest priority.
  • No publicly available challenge or opposition records are noted. However, the European Patent Office (EPO) allows oppositions within 9 months of grant; current status indicates no oppositions filed.

Critical analysis of patent strength

  • The claims are sufficiently specific to prevent easy workarounds.
  • The chemical claims are aligned with prior art, but the specific substituents give the patent novelty.
  • The scope of therapeutic use claims is narrower, reducing the chance of infringing on broad prior art.

Key considerations for stakeholders

  • Patent infringement risk: Companies developing similar compounds must analyze claim language thoroughly.
  • Freedom-to-operate (FTO): The patent landscape is crowded with related filings, requiring comprehensive clearance searches.
  • Patent defensibility: The legitimacy rests on the novelty of the compound and synthesis route.
