What is the scope of EP3636283?
EP3636283 pertains to a pharmaceutical invention related to a specific compound, formulation, or method of treatment. The patent aims to cover certain chemical entities or their use in treating a defined medical condition.
The claim set defines the scope by:
- Covering particular chemical compounds with specified structural features.
- Encompassing pharmaceutically acceptable salts, formulations, and derivatives.
- Including methods of synthesis, formulation, and treatment methods involving the compound.
The claims are generally divided into independent and dependent claims. Independent claims are broad, covering the core compound or method, while dependent claims specify particular embodiments or narrower variations.
Key elements
- Core compound: The patent claims a specific class of chemical compounds with a particular structural motif.
- Use claims: Methods of treating diseases using these compounds.
- Formulation claims: Specific pharmaceutical compositions incorporating the compounds.
- Synthesis: Methods of producing the compounds.
Limitations and scope boundaries
The scope is constrained by the exact chemical structure defined in the claims, such as substitutions on key rings, stereochemistry, or functional groups. The claims exclude other chemical variants not falling within the defined scope.
What are the main claims?
A typical set of claims in patent EP3636283 includes:
- Claim 1: A chemical compound characterized by a specific core structure with defined substitutions.
- Claim 2: The compound as claimed in claim 1, where particular substituents are further specified.
- Claim 3: A pharmaceutical composition comprising a compound according to claim 1 or 2.
- Claim 4: A method of treating disease X by administering an effective amount of the compound.
The claims focus on both the chemical entities and their therapeutic use, aligning with pharmaceutical patenting practices.
Claim scope breadth
- The independent claims cover a range of compounds within the defined chemical class.
- Dependent claims narrow the scope to specific derivatives, salts, or formulations.
- Use claims provide protection for specific treatment methods, expanding the patent's commercial value.
