Type |
Description |
Scope |
| Claim 1 |
Independent |
A pharmaceutical composition comprising a specific active pharmaceutical ingredient (API) formulated for targeted delivery |
Broad, encompasses various formulations of the API for therapeutic use |
| Claim 2 |
Dependent |
The composition of claim 1, wherein the API is a specific chemical compound (e.g., a kinase inhibitor) |
Narrower, specifies the API's chemical class |
| Claim 3 |
Dependent |
The composition includes a specific carrier or excipient |
Adds formulation specificity |
| Claim 4 |
Dependent |
A method of administering the composition to a patient |
Covers administration methods (e.g., oral, injectable) |
| Claim 5 |
Independent |
A method of treating a particular disease by administering the claimed composition |
Focuses on therapeutic application and efficacy |
Scope Analysis
- The claims broadly cover compositions containing the core API with various formulations and methods.
- Narrower dependent claims specify particular chemical structures, excipients, and administration routes.
- The claims aim to secure rights over both composition and method of treatment, common in pharmaceutical patents.
Patent Claims Language and Its Implication
The language within the claims employs standard patent terminology, emphasizing "comprising" (meaning "including but not limited to") to retain broad coverage. The broad claim language allows the patent to cover variations in formulations and related biomedical methods, providing a strong defensive scope against similar inventions.

FAQs
1. What makes U.S. Patent 8,691,185's claims particularly robust?
Their broad language, including "comprising," allows coverage over multiple formulations and methods, making it difficult for competitors to develop similar products without infringement.
2. How does this patent compare to similar patents in the same therapeutic area?
It offers a comparable or broader scope, especially in formulation and method claims, which enhances enforcement potential but faces challenges from patents focusing on structural modifications or combination therapies.
3. Can competitors develop similar drugs that circumvent this patent?
Yes; by designing around the specific chemical structures or formulations claimed, competitors can develop alternative compounds or methods outside the patent's scope.
