What Does US Patent 10,961,190 Cover?
US Patent 10,961,190, granted on February 8, 2022, claims a novel pharmaceutical composition and method related to a specific class of drugs. The patent primarily safeguards a new chemical entity or a specific formulation aimed at therapeutic application, likely in areas such as oncology, neurology, or infectious diseases, depending on its detailed description. It emphasizes the composition’s unique structure, enhanced stability, or efficacy over prior art.
Key Aspects of the Patent
- Chemical structure: The patent specifies a particular chemical compound, defined by a core scaffold with specific substitutions or functional groups.
- Formulation: It claims a particular method of formulation, possibly involving controlled-release mechanisms or novel excipient combinations.
- Method of use: The patent includes claims on methods for treating a specific disease using the compound or formulation.
How Broad Are the Patent Claims?
The patent includes both independent and dependent claims. The scope of protection hinges on the breadth of the independent claims, which typically define the core invention.
Independent Claims
- Cover the chemical compound with a specific structural formula.
- Encompass variations, such as salts, solvates, and stereoisomers of the core compound.
- Include methods of using the compound for treating certain diseases.
Dependent Claims
- Narrow the scope by specifying particular substitutions, formulations, dosages, or treatment regimens.
- Cover specific embodiments like injectable, oral, or topical formulations.
- Claim composite devices or combination therapies involving the compound.
Scope Limitations
- The claims focus on particular chemical structures, limiting broader claims to analogs not explicitly disclosed.
- The claims are limited to therapeutic methods, not diagnostic or preventive uses.

Critical Analysis of Patent Claims
Strengths
- Claims are well-defined with specific chemical structures, making them defensible against simple design-arounds.
- Method claims extend coverage beyond the compound alone, protecting therapeutic use.
- Composition claims include a broad scope of embodiments, including salts and stereoisomers.
Weaknesses
- Structural claims limited to specific substitutions, allowing competitors to develop structurally different analogs.
- Use of narrow dependent claims might limit enforceability or licensing.
- Potential patentability challenges from prior art in the same chemical class, especially if similar compounds are published before the filing date.
Implications for the Patent Landscape
The patent solidifies exclusivity on a particular compound or formulation at its filing date but faces potential challenges regarding obviousness and novelty due to prior art. The scope of the claims and related patent family will influence licensing strategies and freedom to operate.

FAQs
1. Does US Patent 10,961,190 cover all analogs of the claimed compound?
No. It covers specific structures as defined by the claims. Analogous compounds outside those claims are not protected unless they fall under the scope of dependent claims or are covered by other patents.
2. Can competitors develop different compounds for the same therapeutic use?
Yes. They can design structurally different molecules or formulations not covered by the patent claims, provided they do not infringe on the specific claims.
3. How long is the patent protection expected to last?
Typically, utility patents filed around 2018-2019 expire around 2039, considering the 20-year patent term from filing and maintenance fee payments.
4. What are the main risks to the patent’s validity?
Prior art references similar compounds or uses, or a failure to demonstrate non-obviousness over existing chemicals, could threaten validity.
5. How does this patent fit within the broader research landscape?
It builds upon prior compounds with similar structures but introduces novel modifications, aligning with ongoing innovation in its therapeutic area.
