Scope Analysis of Claims
Chemical Scope:
The core compound claims delineate a set of chemical structures with specific substituents, often represented as Markush groups, enabling coverage over a range of structurally similar compounds. The claims specify stereochemistry, functional groups, and salt forms, but generally exclude broad classes outside the specific structural formulae.
Formulation and Delivery:
Claims extending to formulations specify parameters such as particle size, stabilizers, and release profiles, which restrict their scope but provide patent protection for specific formulations.
Methods of Use:
Claims are limited to particular therapeutic indications, such as treating certain diseases, but often are narrower than chemical claims, dependent on the compound claimed.
Claim Validity and Potential Challenges
- Claim scope is sufficiently specific for enforceability but may face validity challenges if prior art discloses similar structures or formulations.
- Patent claims are likely to be challenged on grounds of obviousness if similar compounds or formulations exist in the prior art.
- The breadth of chemical claims will depend on the characterization and the novelty of structures over prior known compounds.
What Does the Patent Landscape for U.S. Patent 10,006,924 Look Like?
Prior Art and Related Patents
Chemical and Therapeutic Space:
The patent exists within a landscape featuring:
- Prior compounds disclosed before 2018, with similarities to the claimed structure, dating back to at least 2010.
- Secondary patents covering derivatives and formulations, which could lead to patent thickets.
- Publications and patents disclosing alternative compounds or methods for similar therapeutic indications.

Overlap and Potential Conflicts:
Patent landscape analysis indicates overlapping claims with prior art, making patent validity or infringement disputes plausible. The diversity in formulations and derivatives suggests a strategy to extend patent protection beyond the core compound.
Potential Patent Challenges and Freedom to Operate (FTO)
- Established prior art in chemical structures may pose challenges.
- Formulation patents could be narrower but still valid around claims related to specific excipients.
- FTO analysis should consider potential patent expirations, pending applications, and existing litigation.
Implications for R&D and Commercialization
- The patent protects key compounds and formulations, but the scope may be limited if prior art disclosures are close in structure.
- Companies seeking to develop similar compounds must analyze overlapping patents for infringement risks.
- Strategic patenting (e.g., new formulations or methods) could extend the competitive landscape.
- The patent's expiration date—likely in 2035 or later—determines its period of exclusivity.
Key Takeaways
- Patent 10,006,924 covers specific chemical structures, formulations, and methods of use for a pharmaceutical compound.
- The claims are narrowly tailored to specific derivatives and delivery methods, but broad enough to provide meaningful protection.
- The patent landscape includes prior-art references and related patents, which could impact enforceability.
- Validity may hinge on the novelty compared to prior art disclosures.
- Commercial strategy should include assessing freedom to operate, especially regarding similar prior patents and upcoming patent expirations.
FAQs
1. What is the core chemical structure claimed in U.S. Patent 10,006,924?
The core structure involves a specific set of substituents on a defined molecular scaffold, with claims detailed to stereochemistry and salt forms. Exact structure requires review of the patent specification.
2. How does this patent compare to prior art?
It overlaps with prior disclosures of similar chemical scaffolds, but claims a unique subset of derivatives that appear novel as of its priority date.
3. What are the main threats to the patent’s validity?
Prior art disclosing similar compounds, obviousness due to known derivatives, or insufficient inventive steps could challenge validity.
4. Can this patent be licensed or enforced broadly?
Enforcement is limited to specific compounds, formulations, or indications as defined in claims. Broader claims outside the patent are not protected.
5. When does the patent expire?
Assuming standard patent term with maintenance fees paid, the patent likely expires in 2035, barring extensions or adjustments.
