Scope and Claims Analysis
Overall Claim Structure
The '073 patent includes:
- Independent Claims: Core claims defining the inventive subject matter, typically broad in scope to cover various embodiments.
- Dependent Claims: Narrower claims adding specific features, improving patent defensibility.
- Method Claims: Covering the therapeutic or manufacturing process.
- Product Claims: Covering the compound or formulation itself.
Main Claims Overview
| Claim Type |
Number of Claims |
Scope & Focus |
| Independent |
3-5 |
Core compounds and methods, often broad. |
| Dependent |
20-30 |
Specific embodiments, dosage forms, combinations, or methods. |
Note: Precise counts and content depend on the actual patent text; typical for drug patents.
Key Independent Claims
- Compound Claims: Cover a novel chemical entity with specific structural features (e.g., a pyrrolopyrimidine core with substituents X, Y, Z).
- Method Claims: Use of the compound for treating specific conditions (e.g., "a method of treating cancer by administering a compound of Formula I").
- Formulation Claims: Specific pharmaceutical compositions comprising the compound, excipients, or delivery systems.
Example (hypothetical):
"A compound of Formula I, wherein the substituents X, Y, Z are defined as...,"
"A method of treating a disease characterized by... comprising administering an effective amount of the compound."
Claim Language and Limitations
- Often include Markush structures for chemical variability.
- Use "comprising" language, allowing for additional ingredients.
- May specify dosage ranges, routes of administration, or treatment duration.
Claim Scope and Offences
- The broadness of claims affords strong infringement potential but may invite patent validity challenges on grounds of obviousness or of claiming an unpatentable genus.
- Overly narrow claims risk being circumvented; therefore, claim drafting likely balanced breadth with specific embodiments.
Patent Landscape and Related Patents
Patent Families and Related Assets
- The '073 patent belongs to a family of patents covering variants, methods, or formulations.
- Prior art likely includes earlier compounds, synthesis techniques, or diagnostic methods.
