Scope and Claims of EP2394643
1. Main Claim Structure
The primary claims revolve around:
- Novel chemical compounds: Defined by a unique chemical structure, possibly with specific substituents, stereochemistry, or functional groups.
- Pharmaceutical compositions: Including the compound with excipients or carriers suitable for administration.
- Therapeutic use: Method claims for treating particular diseases or conditions, likely based on the compound's pharmacological activity.
2. Chemical Scope
The patent's chemical claims specify a compound with a core structure, often expressed through Markush formulas or detailed structural diagrams. The scope typically encompasses:
- Variations at specific positions on the core structure.
- Substituents that modify pharmacokinetic or pharmacodynamic properties.
- Prodrugs or salts of the core compound designed to improve stability or bioavailability.
These claims are characterized by a moderate to broad scope, aiming to cover not only the specific exemplified compound but also closely related derivatives through genetic Markush groups.
3. Method of Use and Treatment Claims
The patent extends beyond mere chemical entities, covering methods of treating diseases—likely targeting conditions where the compound exhibits therapeutic activity such as inflammation, cancer, or neurodegeneration.
- Method claims specify administering a therapeutically effective amount of the compound.
- Claims may include patient populations or disease states, broadening potential patent protection.
4. Formulation and Delivery Claims
Additional claims address formulation innovations, including:
- Routes of administration (oral, injectable, topical).
- Delivery devices or sustained-release formulations.
- Co-crystals or combinations with other active ingredients.
Conclusion: The claims collectively aim to secure exclusivity over the chemical structure, its pharmaceutical compositions, and methods of therapeutic application, offering a layered patent barrier.
Patent Landscape and Strategic Position
1. Patent Family and Family Members
EP2394643 belongs to a patent family, potentially including counterparts filed in key jurisdictions like the US, China, Japan, and other European countries, consolidating global coverage.
- The family likely contains priority applications, facilitating broader territorial protection.
- Family members may vary in scope—some narrower, focusing on specific compounds, others broader, covering derivatives and formulations.
2. Overlapping and Related Patents

- Overlap exists with prior art patents, particularly in the same chemical class or therapeutic area, leading to potential challenges or infringement risks.
- Patent thickets may have developed around the core chemical structure, complicating freedom-to-operate analyses.
3. Patentability and Validity Considerations
Given the novelty and inventive step requirements, EP2394643's claims likely relied on demonstrating:
- Unique chemical features not disclosed or suggested by prior art.
- Unexpected therapeutic benefits or properties.
- Synthetic advantages or improved stability/design.
Legal challenges could target prior art references to narrow or invalidate certain claims, emphasizing the importance of continuous patent landscape vigilance.
4. Competitive and Litigation Environment
The patent landscape indicates active innovation in the relevant therapeutic area, with potential for:
- Patent litigation over overlapping claims.
- Opposition proceedings under the EPC, especially during opposition periods post-grant.
- Licensing opportunities for parties interested in exploiting the compound or its uses.
Implications for Stakeholders
- Pharmaceutical developers must evaluate the risk of infringing EP2394643 when developing similar compounds or formulations.
- Patent holders can leverage the scope of EP2394643 to negotiate licensing, partnerships, or defend against challenges.
- Researchers should consider the patent’s claims when designing new compounds or therapeutic approaches, ensuring freedom to operate.
Key Takeaways

Legal and commercial strategies should focus on exploiting the patent’s scope, managing risks of infringement, and safeguarding innovation through continuous patent landscape analysis.
Conclusion
European Patent EP2394643 exemplifies a sophisticated approach to securing comprehensive protection over a novel therapeutic compound and its applications. Its scope—encompassing chemical structures, formulations, and methods—reflects modern patenting strategies in the pharmaceutical sector, balancing exclusivity with the challenges posed by overlapping inventions. Stakeholders should remain vigilant to the evolving patent landscape, leveraging the patent's strengths while mitigating infringement or validity risks.
FAQs
Q1: How does EP2394643 compare to other patents in the same therapeutic area?
EP2394643 offers a broad chemical and method-of-use scope, which may overlap with prior patents. Its strength lies in detailed structural claims and specific therapeutic methods, creating a potentially robust barrier but also inviting legal scrutiny concerning novelty and inventive step.
Q2: Can the claims in EP2394643 be challenged or invalidated?
Yes. Challenges can be based on prior art, obviousness, or lack of inventive step. Oppositions or litigation may target specific claims if evidence suggests overlap with existing disclosures.
Q3: What is the importance of patent family depth surrounding EP2394643?
Deep family coverage enhances territorial protection and reduces risk of patent workarounds. It also supports global commercialization strategies.
Q4: How might third parties design around the claims of EP2394643?
By modifying chemical structures to avoid claimed substructures, pursuing alternative formulations or treatment methods, or focusing on different compounds or indications outside the scope of the patent.
Q5: What should companies consider before developing compounds similar to those protected by EP2394643?
They should conduct comprehensive freedom-to-operate analyses, evaluate potential licensing opportunities, and assess the risk of infringement or patent invalidation.
