As the European patent landscape continues evolving, understanding the scope, claims, and positioning of EP3390395 is critical for stakeholders—pharmaceutical companies, investors, and legal strategists aiming to navigate patent rights effectively.
This analysis dissects the patent's scope, claims, and its position within the broader clinical and commercial patent landscape.
Scope of EP3390395
The scope of EP3390395 encompasses a specific chemical entity, a pharmaceutical composition, or a therapeutic method—in line with typical drug patents. The scope is primarily delineated by the claims, which define the legal boundaries of the patent rights.
The patent's claims likely cover:
- A novel compound characterized by unique chemical structures or derivatives.
- A pharmaceutical composition comprising the novel compound, possibly combined with excipients or other active ingredients.
- Methods of use, especially therapeutic methods targeting particular diseases or indications.
The patent's scope appears to focus on treating specific medical conditions, potentially including cancer, neurological disorders, or infectious diseases, depending on the disclosed mechanism of action.
The scope can be broadly categorized into:
- Compound claims: Covering the chemical entities with defined structural features.
- Formulation claims: Covering specific pharmaceutical compositions containing the compound.
- Method claims: Covering use in therapy, including dosing regimens or combination therapies.
Analysis of the Claims
1. Claim Structure & Types
European patents typically contain:
- Independent claims: Broad, overarching claims establishing the core inventive concept.
- Dependent claims: Narrower claims adding specific limitations, such as modifications, specific uses, or formulations.
In EP3390395, the primary independent claims likely define the compound's chemical structure or formula. Subsequent dependent claims specify:
- Variations in chemical substituents.
- Specific crystalline forms or salts.
- Particular formulations optimally suited for administration.
- Therapeutic methods applying the compound for treatment of certain diseases.
2. Chemical Scope
The chemical scope likely covers a class of compounds, such as heterocyclic derivatives, with specific substituents or stereochemistry. The claims probably specify core structural elements with permissible modifications, providing a balance between breadth and novelty.
3. Novelty & Inventive Step
The patent claims appear to be drafted to emphasize the novelty over prior art by:
- Introducing unique substitutions or conformations.
- Demonstrating surprising therapeutic effects or improved pharmacokinetics.
- Covering unforeseen uses or combinations.
The inventive step hinges on unexpected efficacy or safety advantages over existing therapies or compounds.
4. Limitations and Prior Art
The scope carefully delineates over prior art by defining the chemical core and substituents, ensuring the claims are neither overly broad nor easily invalidated. Prior arts may include similar heterocyclic compounds or prior art pharmaceutical formulations; thus, the patent emphasizes structural distinctions or specific therapeutic advantages.

- Method patents for specific therapeutic uses.
Understanding overlaps is crucial, to avoid infringing on existing rights or to identify freedom-to-operate (FTO) opportunities.
2. Patent Families and International Coverage
The patent family likely includes:
- Equivalent filings in jurisdictions like the US, Japan, China, and other key markets, ensuring global protection.
- Extension applications or continuations refining or broadening claims.
3. Freedom-to-Operate & Exclusion Zones
Determining potential conflicts involves:
- Analyzing prior art documents cited during prosecution.
- Monitoring overlapping patent families.
- Identifying patent expiration timelines that could open commercial pathways.
4. Market and Competitive Position
The patent's scope, especially its claims' breadth, influences its strategic value in:
- Securing exclusivity.
- Licensing negotiations.
- Development of follow-on compounds or formulations.
It positions the assignee within a competitive therapeutic class, especially if it covers key chemical variants or specific therapeutic uses.
