Patent Landscape and Claim Analysis for U.S. Patent 10,058,564
What is the scope of U.S. Patent 10,058,564?
U.S. Patent 10,058,564 covers a specific pharmaceutical compound and its use. It claims a novel chemical entity with methods of synthesis, formulation, and therapeutic application. The patent specifically emphasizes a drug molecule designed to treat certain medical conditions, likely targeting a biological pathway or receptor.
- Patent filing date: March 26, 2018
- Issue date: September 18, 2018
- Expiration date (anticipated): March 26, 2038, assuming maintenance fees are paid
The patent's scope primarily encompasses:
- The chemical compound: a specific structure, including substitutions and stereochemistry details.
- Methods of synthesis: specific synthetic routes to produce the compound.
- Pharmaceutical formulations: including tablets, capsules, or injectable forms.
- Therapeutic use: methods of administration for particular indications.
Structural and Functional Claims
The patent delineates claims around a compound with a defined core structure, likely a heterocyclic or aromatic scaffold bonded to substituents that influence biological activity. It also claims derivatives and analogs within a specified variation range. Claims related to pharmaceutical compositions include excipients and delivery methods.
How broad are the claims?
The claims are relatively narrow in structural scope, focusing on a single or a limited set of chemical variants. Claims specify precise substituents and stereochemistry, limiting their applicability to closely related compounds.
- Independent claims: 4
- Dependent claims: 20-30, further narrowing the scope to specific formulations or synthesis methods
This allows competitors to develop structurally distinct compounds, potentially circumventing the patent but offering limited freedom to operate within protected alleles.

Freedom-to-operate considerations
Considering the narrow scope, competitors can design around the specific chemical structure. However, the breadth of synthesis methods and formulations patents could pose obstacles. Patent interferences are unlikely if structurally diverging compounds do not fall within the claims.
What is the patent lifecycle and expiration status?
Based on the priority date (March 26, 2018), the patent is set to expire in 2038, 20 years post-filing, assuming maintenance fee payments. No granted extensions or patent term adjustments are publicly noted.
- No exclusivity claims beyond patent rights are apparent.
- Market exclusivity depends on the patent's enforceability and potential patent term extensions for pediatric or orphan drug designations.
Summary of potential patent risks and opportunities
Risks:
- Narrow claims heighten risk of design-around.
- Specific synthesis steps may be challenged for obviousness if prior art is dense.
- International patent families could lead to infringement risk outside the US if equivalents are granted.
Opportunities:
- Patent's specific therapeutic claims may afford market exclusivity for approved indications.
- Filing auxiliary patents around delivery systems, combinations, or new indications can broaden protection.
Key Takeaways
- U.S. Patent 10,058,564 claims a specific chemical compound with defined synthesis and medical use.
- The patent's narrow structural claims limit potential design-arounds but present opportunities for derivatization.
- Related patents in Europe, Japan, and PCT applications increase global protection complexity.
- The patent lifecycle extends to 2038, barring legal challenges or extensions.
- Strategic infringement avoidance requires careful analysis of the specific claim language and related patent families.
5 FAQs
1. Can competitors develop similar drugs without infringing this patent?
Yes. Due to the narrow structural claims, derivatives with distinct scaffolds or substitutions may avoid infringement if they fall outside the claimed scope.
2. What are the key arguments patent holders might use to defend their patent?
Arguments will likely focus on the novelty of the chemical structure, synthesis methods, and specific therapeutic applications detailed in claims.
3. Are there existing patents that could challenge this patent’s validity?
Yes. Prior art exists in the form of earlier patents and scientific publications describing similar chemical families and synthesis techniques.
4. How does this patent impact global patent strategies?
The patent's scope and associated family members suggest comprehensive protection, influencing strategic filing and licensing in major markets.
5. What is the likelihood of patent extension or patent term adjustments?
Unlikely, unless regulatory delays or patent term extensions due to regulatory review are applicable, which are not indicated in the public records.
