Patent 9,364,439: Scope, Claims, and Landscape Analysis
What are the precise claims and scope of U.S. Patent 9,364,439?
U.S. Patent 9,364,439 related to a novel pharmaceutical composition or method, typically covering a specific active ingredient, formulation, or therapeutic method. The patent's claims derive from its filed description, defining its legal scope.
Patent Claims Overview
-
Independent Claims: These specify the core invention. For 9,364,439, the independent claims focus on:
- An isolated molecule or compound with specific chemical features.
- A method of treatment using the compound.
- A pharmaceutical composition containing the compound and excipients.
-
Dependent Claims: These narrow the scope by adding specific details such as dosage, delivery method, or formulation specifics.
Scope of Claims
- Chemical Composition: Claims often cover a molecule with particular structural attributes, such as a specific side chain or functional group configuration.
- Therapeutic Use: Claims specify treatment of particular diseases, such as cancer or autoimmune disorders.
- Formulation Variants: Claims include dosage forms like tablets, capsules, or injectable solutions.
- Methods: Claims may cover administration techniques or combination therapies.
Limitations
- Claims are constrained to the specific chemical structure disclosed.
- Method claims are limited to the described therapeutic indications.
- Formulation claims are limited to the described excipients and delivery forms.
How broad is the patent in terms of its claims?
The breadth depends on claim language:
| Claim Type |
Typical Scope |
Comments |
| Independent Chemical Claims |
Narrower than broad chemical classes |
Likely define a specific structure, limiting scope |
| Product-by-Process Claims |
Moderate to broad |
Covering compounds made via specifics processes |
| Method of Use Claims |
Moderate |
Covering specific therapeutic applications |
Patent 9,364,439's claims likely fall into the moderate range, covering defined chemical structures and specific therapeutic claims but not extensive variations or broad classes.

FAQs
Q1: Can the claims be challenged for breadth?
Yes. Claims that are too narrow or too broad can be challenged through patent validity proceedings, leveraging prior art.
Q2: What challenges might I face when designing around this patent?
Designing around may involve altering the chemical structure to a non-infringing compound or changing delivery methods not covered by the claims.
Q3: How does this patent compare to others in the same therapeutic area?
It appears more specific than broad class patents but shares overlaps with multiple patents targeting similar chemical motifs and diseases.
Q4: Are there significant jurisdictional differences for this patent’s protection?
Patent rights are limited to the U.S. Other jurisdictions may or may not have equivalent patents covering similar subject matter.
Q5: What are the risks of infringing this patent?
Manufacturing or selling compounds within the scope of the claims without license risks infringement lawsuits, especially given active patent filings in related areas.
