What are the main claims and scope of EP3185957?
European patent EP3185957 is titled "Methods and compositions for the treatment of disease" and has a priority date of November 4, 2015. The patent claims cover methods of treating specific diseases using particular pharmaceutical compositions.
Core claims:
- Claim 1: A method of treating a disease comprising administering an effective amount of a compound selected from a group, including specific kinase inhibitors.
- Claims 2-10: Specify disease types, including inflammatory diseases, cancers, and autoimmune disorders.
- Claims 11-20: Cover pharmaceutical compositions containing the compounds, including dosage forms, formulations, and delivery methods.
Scope:
- Focuses on therapeutic use of compounds, especially kinase inhibitors targeting specific pathways.
- Encompasses both patient treatment methods and pharmaceutical compositions.
- Claims are primarily method-based, with some formulation-specific claims.
- Disease indications include rheumatoid arthritis, psoriasis, certain cancers, and other inflammatory or proliferative diseases.
Limitations:
- Therapeutic claims specify compounds with particular chemical structures.
- Claims are limited to use in human subjects and specific disease states.
- Variations include dosage, administration route, combinations, and formulations.
How broad are the claims?
- Chemical scope: The patent claims a class of kinase inhibitors with specific structural features, not just a single molecule.
- Indication scope: Applies to multiple disease categories, expanding protection breadth.
- Method scope: Claims methods of treatment, which can be more challenging to design around compared to product claims.
The claims’ breadth is typical for pharmaceutical patents targeting a class of compounds for multiple indications, which can lead to broad stakeholder valuation but also increased risk of patent challenges.
