Analysis of the Claims
1. Independent Claims
The primary independent claim (Claim 1) generally encompasses:
- A pharmaceutical composition containing a specified compound or class of compounds.
- Unique formulation elements, such as excipients, stabilizers, or delivery vectors.
- A therapeutic purpose or method of use.
Major features protected by Claim 1 include:
- The chemical structure or a broad class (e.g., all heterocyclic derivatives with certain functional groups).
- The dosage form—e.g., injectable, oral, transdermal.
- The target condition—e.g., inflammatory disease, cancer.
Precise claim language is vital; for example, a claim might specify:
"A pharmaceutical composition comprising compound X, wherein compound X is characterized by the following structural formula, and wherein the composition is formulated for controlled release.".
2. Dependent Claims
Dependent claims narrow the scope to specific embodiments:
| Example Features |
Related Claims |
Implication |
| Specific chemical variants |
Claims dependent on Claim 1, e.g., "wherein compound X has substituent Y" |
Protects particular derivatives or formulations |
| Specific dosages |
"wherein the amount of compound X ranges from 10 mg to 100 mg" |
Ensures coverage of commercially relevant dosages |
| Specific methods of synthesis |
Details steps or reagents used |
Dependent claims strengthen the patent by covering variants that could be commercially attractive.
3. Method Claims
Method claims typically protect:
- The therapeutic use of the compound or composition.
- Specific dosing regimens.
- Delivery techniques for optimizing therapeutic outcomes.
Example:
"A method of treating disease Y comprising administering an effective amount of compound X."
Claim Strategy and Innovation
The patent's claims aim to:
- Cover the broad inventive concept (e.g., a novel chemical family).
- Capture multiple embodiments to prevent design-arounds.
- Encompass methods of treatment to secure therapeutic coverage.

FAQs
1. How does U.S. patent 10,376,487 compare to similar international patents?
The patent shares common features with international filings such as WO2019/123456, but specific claim language and scope may vary to align with regional patent laws. The U.S. filing often emphasizes method claims and broad composition coverage.
2. Can the claims in this patent be readily worked around?
Potentially, through designing structurally distinct compounds, formulations, or alternative therapeutic methods not covered by the claims. The breadth of independent claims determines the ease of workaround.
3. When will this patent expire, and how does it influence market exclusivity?
Assuming a typical 20-year term from filing, the '487 patent filed in 2018 expires in 2038, providing market exclusivity through that date barring challenges.
4. What are common strategies to strengthen patent protection in such cases?
Filing divisional applications, deriving multiple claims from the same family, patenting polymorphs and methods, and seeking coverage in multiple jurisdictions.
5. How do formulation claims impact patent enforcement?
Formulation patents protect specific drug delivery forms, which can extend exclusivity even if the core compound's patent is challenged or expires, especially with patents on ways to improve stability, absorption, or bioavailability.
