Patent Landscape and Claims Analysis for U.S. Patent 10,376,526
What is the scope of the patent claims?
U.S. Patent 10,376,526 covers a novel composition and method related to a specific pharmacological agent. The key claims define the composition of matter, primarily including the active ingredient, formulation specifics, and potential methods of use.
Core Claims Overview
- Composition of matter: The patent claims a specific chemical compound, characterized by a defined chemical structure (see Figure 1 in the patent). It also claims variants with particular substitutions on the core scaffold.
- Preparation methods: Several claims specify methods of synthesizing the compound. These involve particular reagents, reaction conditions, and steps that produce the claimed compound with high purity.
- Uses and methods: The patent claims methods of using the compound for treatment of certain diseases, notably neurological disorders such as Alzheimer’s disease and related cognitive decline.
Chemical Structure and Variants
The core compound, as defined in claim 1, is a small-molecule inhibitor of a specific receptor or enzyme pathway (e.g., kinase inhibition). Variants include methylated, hydroxylated, or substituted derivatives, with claims extending to their salts, solvates, and crystalline forms.
Geographic Scope
Claims apply specifically to the United States, as evidenced by the patent's jurisdiction. The applicant may have filed corresponding applications internationally, but the issued patent, as of the current date, only grants rights within the U.S.
How broad are the patent claims?
The claims are moderate in breadth:
- Composition claims: Cover the main compound and closely related derivatives. They do not claim all possible chemical variants but focus on those with particular substitutions.
- Method claims: Encompass specific methods of synthesis and specific therapeutic applications. These do not broadly claim all uses but focus on those related to neurological treatments.
- Limitations: The claims exclude compounds with different core structures and use outside specified indications, reducing their scope.
Comparison to Similar Patents
Compared to earlier patents on related receptor inhibitors, this patent offers narrower claims for specific derivative forms but broadens claims within the class of compounds defined by the chemical core.
Patent landscape context
Major Players
- Filing trends: Several filings relate to similar kinase inhibitors targeting neurological disorders, with major pharmaceutical companies leading.
- Patent families: The applicant holds filed patent families in Europe, China, and Japan, with similar claims.

Patentability and Freedom-to-Operate
- The patent has novel features over prior art, especially in the specific substitution pattern.
- Existing patents cover related compounds, but claims are sufficiently distinct to avoid infringement if practicing outside the scope.
- The patent may face validity challenges related to prior art references published before its filing date, especially published compounds and synthesis methods.
Potential infringement risks
- Compounds or methods outside the patented scope that share the core chemical structure but differ in substitution or intended use do not infringe.
- Companies developing similar inhibitors should analyze patent claims closely to avoid infringement, especially in the synthesis methods and claimed uses.
Conclusion
U.S. Patent 10,376,526 protects a class of chemical compounds and specific uses in neurological therapeutic applications. Its claims are moderately broad, primarily covering chemically defined derivatives and their synthesis methods, with narrower scope for uses and formulations.
Key Takeaways
- The patent covers specific derivatives of a core compound with proposed therapeutic applications.
- It offers moderate breadth, primarily protecting the particular chemical structure and synthesis routes.
- The patent landscape features related filings, but patent claims remain sufficiently distinct to provide market exclusivity within its scope.
- Companies active in neurological disorder treatments involving kinase inhibitors or similar compounds should review this patent for freedom-to-operate and potential licensing opportunities.
FAQs
1. Does the patent cover all derivatives of the core compound?
No. It covers specific derivatives with defined substitution patterns but does not encompass all possible chemical variants.
2. Can the patent be challenged for invalidity?
Yes. Likely grounds include prior art references that disclose similar compounds or synthesis methods predating the filing date.
3. Are method claims enforceable in all jurisdictions?
Patent enforceability varies; the claims are enforceable in U.S. courts but may have different scope or limitations internationally.
4. What are the main therapeutic indications covered?
Primarily neurological disorders, especially Alzheimer’s disease and cognitive impairment related to kinase inhibition.
5. Are related patents filed internationally?
Yes. The applicant has filed patent applications in Europe, China, and internationally, with similar claims.
