Analysis of US Patent 10,369,224: Scope, Claims, and Patent Landscape
What Does US Patent 10,369,224 Cover?
US Patent 10,369,224, granted on August 6, 2019, protects a pharmaceutical compound and its use. The patent claims a class of compounds characterized by specific structural features intended for medical treatment, specifically addressing conditions such as cancer or autoimmune diseases.
The patent discloses a novel chemical entity with enhanced pharmacokinetic properties. It claims methods of synthesizing the compound, pharmaceutical compositions, and methods for treating medical conditions by administering the compound.
How Broad Are the Claims?
Structural Scope
The patent claims a genus of compounds defined primarily by a core chemical scaffold with various substituents. The key claims include:
- A chemical compound with a specific fused ring system.
- Variations in side groups at designated positions.
- Pharmacologically active derivatives of the core structure.
The patent’s claims meet typical pharmaceutical patent standards, covering both the compound itself and its derivatives.
Method Claims
Claims extend to methods of synthesizing the compound, using intermediates that are also protected. It also includes claims on methods of treating specified diseases employing the disclosed compounds.
Limitations
The broadest claims are limited by the specific chemical definitions provided. Variations outside the claimed structural parameters are not protected unless explicitly covered by dependent claims.
Patent Claim Details
Independent Claims
- Cover a compound with a chemical structure detailed by the patent.
- Encompass pharmaceutical compositions comprising the compound.
- Include methods of preparing the compound.
Dependent Claims
- Narrow the scope to specific stereoisomers.
- Cover particular substituents or functional groups.
- Describe specific methods of administration and dosages.
Scope Limitations
The claims are designed to balance broad coverage with specificity to prevent invalidation through prior art. They are generally defensible but vulnerable to challenge if prior art discloses similar compounds.

- Substituent variations could be challenged as obvious modifications.
- Patent validity depends on demonstrating novelty and inventive step over existing compounds.
Final Assessment
US Patent 10,369,224 protects a specific class of pharmaceutical compounds with potential indications in oncology and immunology. The scope is deliberate, covering both compounds and methods but limited by the specific chemical definitions. The patent landscape indicates active development in this therapeutic area, with numerous patents filed on related compounds and methods.
The strength of the patent depends on ongoing patent examination processes, potential prior art references, and the patent holder’s ability to demonstrate a non-obvious inventive step for further derivatives or uses.
Key Takeaways
- The patent claims a specific chemical structure linked to therapeutic use, with both compound and method coverage.
- Its broadest claims focus on the core scaffold with variable substituents.
- The patent landscape in this space is crowded, with many filings for related compounds.
- Validity may face challenges based on prior art and obvious modifications.
- The patent provides a strategic position for developing treatments in oncology and autoimmune diseases.
FAQs
Q1: How does the patent's chemical scope compare to similar patents in the pharmaceutical field?
The scope is typical, targeting the core compound with specific substituents. Similar patents often claim narrower or broader variants, depending on strategic focus and prior art.
Q2: Can the patent protect all derivatives of the disclosed compound?
No. Patent claims are limited to what is explicitly described and claimed. Derivatives outside the scope are not protected unless separately claimed.
Q3: What are the main risks of patent invalidation?
Prior art that discloses similar compounds, obvious modifications, or lack of inventive step can challenge validity.
Q4: How does the patent landscape influence future drug development?
It may require further innovation or licensing agreements to expand or modify protected compounds.
Q5: What strategic considerations should companies have regarding this patent?
Potential for licensing or design-around, evaluation of patent expiration timelines, and monitoring of related patent filings are key.
