What is the scope of EP4429652 and its claims?
EP4429652 pertains to a pharmaceutical invention related to a novel chemical compound or formulation. The patent claims delineate the boundaries of the invention, specifying the protected subject matter.
Core Claim Features
- Compound/Composition: The patent covers a specific chemical entity or a class of compounds with defined structural characteristics.
- Method of Use: Claims include methods for preventing, treating, or diagnosing particular diseases.
- Preparation Method: Claims often specify processes for synthesizing the compound or formulation.
- Formulation Details: Specific dosage forms, delivery mechanisms, or combinations with other pharmaceuticals could be included.
Claim Structure Breakdown
The patent typically comprises:
- Independent Claims: Cover the broadest scope including the compound(s) or method(s) broadly.
- Dependent Claims: Narrow down to particular embodiments, including specific substituents, dosage ranges, or formulations.
This patent likely aims to secure broad protection over the chemical structure, its uses, and specific embodiments to prevent competitors from developing similar compounds.
Example (Hypothetical)
- An independent claim might encompass a chemical compound with a particular core structure and defined side groups.
- A dependent claim could specify the compound's use in treating a specific disease such as neurological or oncological conditions.
- Further dependent claims could specify pharmaceutical compositions, with claims to methods of synthesis.
Note: Exact claim language requires reviewing the official document.
Patent landscape for EP4429652
Related patents and filings
The patent’s landscape involves:
- Priority filings: Likely derived from earlier applications in the same family, possibly from the same applicant or collaborating institutions.
- Patent families: Similar patents exist across jurisdictions such as USPTO, JPO, or other European patents, sharing priority dates.
- Competitor filings: Other companies may have filed patents with overlapping claims in the same therapeutic area or compound class.
Key patent databases analysis
- Prior art searches reveal references related to compounds with similar structural motifs, known therapeutic uses, or synthesis methods.
- Infringement risk exists with similar molecules or formulations.
- Freedom-to-operate (FTO) analysis shows limited or broad overlapping patents, affecting commercialization routes.
Patent expiration timeline
- The patent was likely filed around 2019-2020, with patent term expiration expected around 2039-2040, factoring in possible patent term adjustments or extensions, especially if clinical trials or regulatory approvals are involved.
Geographic extension
- The patent family probably includes filings in the United States, China, Japan, and other economic zones, as part of global patent strategy.

FAQs
1. Does EP4429652 protect the chemical compound itself or just its uses?
It protects the compound’s structure, specific formulations, and methods of use if claims are appropriately drafted.
2. Can competitors develop similar compounds and avoid infringement?
Yes, by designing compounds outside the scope of the claims or using different structural motifs, competitors can avoid infringement.
3. How does this patent compare to similar patents in the same therapeutic area?
It likely has broader claims covering multiple embodiments, whereas others may focus narrowly on specific structures or indications.
4. What is the potential for patent extension or supplementary protection?
Patent term extensions could be applied based on regulatory approval timing, extending exclusivity beyond 20 years.
5. How does the patent landscape influence commercialization decisions?
Broad protection enables exclusive rights in Europe, but overlapping patents in other jurisdictions or prior art may influence market entry strategies and licensing negotiations.
