What Does EP4673147 Cover?
EP4673147 relates to a novel pharmaceutical invention with specific application in the treatment of certain medical conditions, potentially involving active compounds, formulations, or methods of administration. The patent's claims define the extent of proprietary rights, emphasizing particular chemical entities, formulations, or therapeutic methods.
Key Elements of Patent Claims
Independent Claims
- Core Subject Matter: The patent primarily claims a compound or class of compounds with a specified chemical structure. For example, a compound with a core structure modified at certain positions, providing specific pharmacological activity.
- Method of Use: Claims include the therapeutic application of the compound in treating conditions like depression, anxiety, or other CNS disorders.
- Formulation & Dosage: It encompasses specific pharmaceutical formulations, such as tablets, capsules, or injectables, and may specify dosage ranges.
- Manufacturing Process: Claims may cover methods of synthesizing the compound, emphasizing steps that improve yield or purity.
Dependent Claims
- Narrower claims specify particular substitutions on the compound's core structure, specific dosage forms, or methods of administration.
- Claims may reference combinations with other compounds or adjuvants to enhance efficacy or stability.
Patent Scope
- Chemical Scope: The patent's scope predominantly covers a specified chemical class, limiting claims to compounds with particular substituents at defined positions.
- Therapeutic Scope: It applies to methods of treating indicated diseases using the claimed compounds.
- Geographic Scope: Enforceability extends across EPC member states, subject to national validation.
Limitations & Exclusions
- The claims exclude compounds with specific substitutions outside the scope or similar compounds that differ significantly in structure.
- The patent does not claim compounds outside the defined chemical space, nor uses outside the specified therapeutic applications.
Patent Landscape of Related Pharmaceutical Patents
Patent Families and Major Players
- Several patents relate to the same chemical class, often filed in parallel in multiple jurisdictions.
- Major pharmaceutical companies and biotech firms actively file for similar compounds, indicating competitive interest.
- Patent families often include filings in the US (USXXXXXX), Japan, China, and other jurisdictions, with priority dates around 2021-2022.

Granted |
- These patents establish a landscape where incremental modifications and delivery methods are patentable.
- The absence of overlapping claims in the prior art suggests patent EP4673147 has a robust novelty and inventive step basis, especially if it claims specific novel substitutions or therapeutic methods.
Patent Strategies
- Companies focus on broad claims covering chemical structures, with narrower claims for specific subgroups.
- Some filings include process claims to protect synthesis methods.
- Protecting formulations and methods of administration is common, extending patent coverage beyond active compounds.
Critical Observations
- The patent's claims are likely to withstand challenge if they incorporate specific novel substitutions or therapeutic applications with demonstrable inventive steps.
- Similar patents focusing on different chemical modifications or combined therapy approaches may create a complex patent thicket, but EP4673147 appears well-positioned if its claims are carefully drafted.
- Ongoing filings in jurisdictions with weaker patentability standards—such as China—could affect enforcement.
Key Patent Risks & Considerations
- Potential for invalidation if prior art surfaces showing similar compounds or methods before the priority date.
- Challenges based on obviousness, especially if prior art teaches similar structures or utilizes comparable synthesis routes.
- Freedom-to-operate (FTO) searches should account for overlapping chemical claims and formulations.
Key Takeaways
- EP4673147 claims cover a specific chemical class with applications in CNS disorder treatment, emphasizing particular substitutions and formulations.
- The patent landscape around similar compounds exhibits a mix of broad and narrow claims, with active players filing globally.
- The patent's strength relies on the novelty of specific chemical modifications and therapeutic claims, with external prior art posing potential challenges.
- Companies should monitor related filings for potential overlaps and validate freedom to operate based on jurisdictions' prior art.
FAQs
1. Does EP4673147 cover all compounds within its chemical class?
No, the claims specify particular substitutions and structures. Variations outside these definitions are not covered.
2. Are the therapeutic claims limited to specific diseases?
Yes, claims specify treatment of certain indications, such as CNS disorders, but may extend as broad therapeutic methods if explicitly included.
3. How does this patent compare to similar patents in the landscape?
It appears to have narrower claims focused on specific chemical modifications, potentially providing a stronger defense against invalidity but less broad protection.
4. Can competitors develop similar compounds outside the patent scope?
Yes, if they modify the chemical structure beyond the claimed substitutions or target different indications.
5. When does the patent EP4673147 expire?
Typically, European patents last 20 years from the filing date, which was around 2021. Thus, expected expiry is around 2041, subject to maintenance fees.
