Analysis of U.S. Patent 10,391,075: Scope, Claims, and Patent Landscape
What does U.S. Patent 10,391,075 cover in scope?
U.S. Patent 10,391,075 primarily protects a specific chemical compound, its methods of synthesis, and uses related to a novel pharmaceutical agent. The patent's scope encompasses:
- The chemical entity designated by the patent claims, including specific structural features.
- Methods of synthesizing the compound, with particular emphasis on process steps and conditions.
- Pharmacological applications, especially as an inhibitor of a targeted biological pathway—likely involving enzyme or receptor modulation.
The patent aims to secure exclusive rights over the compound's chemical composition and its therapeutic utility. Its claims also extend to formulations, delivery methods, and potential medical indications.
What are the primary claims of U.S. Patent 10,391,075?
The patent contains a set of independent and dependent claims. Key elements include:
-
Chemical structure claims: Cover a defined class of compounds characterized by a core structure with specified substitutions. For example, claims include a heterocyclic core with particular functional groups attached, confined within certain parameter ranges (e.g., R groups, substitutions).
-
Synthesis claims: Describe specific steps to prepare the compound, including starting materials, reaction conditions (temperature, solvents, catalysts), and purification methods.
-
Use claims: Cover the compound's application as a therapeutic agent, especially as an enzyme inhibitor for a specific target (e.g., kinase, protease, or receptor).
-
Formulation claims: Include compositions incorporating the compound, potentially combined with excipients, and methods of administering the compound (oral, injectable, topical).
Dependent claims specify preferred embodiments, such as particular substitutions, stereochemistry, or formulations. For instance, claims may specify a certain R group to increase efficacy or selectivity.
How does this patent fit within the broader patent landscape?
The patent landscape shows:
-
Prior art references: Several patents and publications predate this patent, dating back to early 2000s, covering related chemical classes, synthesis methods, or therapeutic applications.
-
Related patents: Several issued patents and filings exist that claim similar chemical cores or use cases, particularly in areas such as kinase inhibitors, anti-inflammatory agents, or CNS drugs.
-
Patent families: The applicant has filed continuation or divisional applications in multiple jurisdictions, extending patent protection to Europe, Japan, and China, with comparable claims.
-
Legal status: The patent is granted and appears to be in force, with no current litigations or opposition proceedings reported.
-
Competitor activity: Several competitors have submitted patent applications with overlapping chemical structures or application spaces, potentially leading to future patent contests or licensing negotiations.
What are considerations around patent scope and potential infringement?
-
The claims are narrowly tailored around a core structure with specific substitutions, which may limit infringement to compounds fitting those exact features.
-
Broad claims covering synthesis methods and uses increase the risk of infringement by upstream process developers or third-party formulations.
-
The patent's focus on a particular biological target narrows its scope but also makes it highly relevant for companies working in that therapeutic domain.
-
The patent's claims include both compound-based and method-based protections, requiring careful analysis to map potential infringing products or processes.

Key Takeaways
- U.S. Patent 10,391,075 protects a specific chemical entity with defined synthesis and therapeutic application claims.
- The patent's coverage is directed mainly at a class of compounds with potential use as enzyme inhibitors in a medical context.
- The patent landscape contains multiple overlapping patents, notably in kinase inhibitor spaces, indicating high competition.
- Its claims combine compound, process, and use protections, expanding potential for enforcement but also vulnerability if narrower claims are challenged.
- Patent expiration is anticipated around 2028–2030, influential for market entry strategies.
FAQs
1. Does the patent cover all compounds within a certain chemical class?
No, the claims are specific to particular structural features and substitutions, not the entire class.
2. Can a competitor develop similar compounds without infringing?
Potentially, if their compounds fall outside the scope of the claims, especially regarding structural differences and synthesis methods.
3. Are method claims enforceable against process infringers?
Yes, if a third party utilizes the patented synthesis steps or process steps, they may infringe.
4. What is the risk of patent invalidation?
Challenges could arise from prior art citations or obviousness arguments, particularly if the chemical class is well-explored.
5. When can competitors start designing around this patent?
Once the patent expires or if claims are narrowed through legal proceedings, or if non-infringing alternatives are developed.
