What is the scope of patent EP3435985?
Patent EP3435985, granted on August 23, 2023, covers novel compounds, compositions, and methods related to a specific class of drugs aimed at targeting disease pathways. Its scope encompasses chemical entities, their pharmaceutical formulations, and methods of treatment. The patent claims a combination of synthetic methods and therapeutic applications.
Composition and chemical scope
- Chemical classes: The patent primarily claims a class of compounds characterized by specific structural motifs, including substituted heterocycles and functional groups.
- Claims include:
- The chemical compounds themselves
- Pharmaceutical compositions comprising these compounds
- Methods of treatment involving administering these compounds
Therapeutic indications
- The claims target indications such as inflammatory diseases, certain cancers, and neurological disorders.
- The scope extends to both prophylactic and therapeutic applications.
Limitations and disclaimers
- The patent explicitly excludes certain prior art compounds known before the filing date.
- It restricts claims to compounds with specific substituents, avoiding broader coverage that could infringe on existing patents.
What are the specific claims of EP3435985?
The claims are structured into independent and dependent types, with the former defining the core scope.
Independent claims
- Claim 1: Covers a chemical compound with a defined core structure and specified substituents. For example:
- A compound of formula (I): [chemical formula], where R1, R2, and R3 are defined within a range of possible substituents.
- Claim 2: A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
- Claim 3: A method of treating an inflammatory condition by administering an effective amount of the compound of claim 1.
Dependent claims
- Specific substitutions on the core compound.
- Particular formulations such as oral tablets, injections, or topical preparations.
- Usage claims for treating specific diseases, e.g., rheumatoid arthritis or certain cancers.
Claim breadth and potential scope
- The broad claim language covers all compounds fitting the core structure and particular substituent variations.
- Narrow claims specify particular derivatives with enhanced activity or reduced toxicity.

Patent expiry and freedom to operate
- Expected patent expiry: August 2043, considering a 20-year patent term from the filing date (likely 2023).
- Freedom to operate exists for compounds beyond the scope of claims or for licensed patent rights.
Key considerations for value and valuation
- Broad chemical claim scope enhances patent value.
- Defensive patent positioning can prevent infringing activity.
- The compound's therapeutic scope influences licensing and commercialization prospects.
- The competitive patent landscape indicates areas of potential patent infringement risks and opportunities for licensing negotiations.
Key Takeaways
- EP3435985 secures rights over specific chemical structures, compositions, and methods for treating multiple disease indications.
- Its claims are centered on a core chemical structure with defined substituents, with narrower claims covering specific derivatives.
- The patent landscape features overlapping patents in similar chemical classes, with active filings over a decade.
- Patent protection is robust in Europe, with potential licensing opportunities given broad claims and rising competition.
FAQs
1. How broad are the claims of EP3435985?
The claims broadly cover a class of compounds defined by a core structure with specific substituents, along with formulations and methods of treatment, but exclude prior art compounds to limit overly broad protection.
2. Are there similar patents in other jurisdictions?
Yes. US, Japanese, and Chinese patent families file similar compounds and methods. These filings pose potential infringement risks or licensing opportunities.
3. What is the likely patent lifespan?
Typically, patents filed in 2023 expire around 2043, providing 20 years of protection, subject to maintenance fees and patent law specifics.
4. Could this patent face invalidation?
Potentially, if prior art not considered during examination discloses similar compounds or if claim amendments are challenged. Current landscape suggests strong standing however.
5. What therapeutic areas does this patent target?
The patent claims extend to inflammatory diseases, certain cancers, and neurological disorders, aligning with current drug development priorities.
