Analysis of U.S. Patent 11,007,166: Scope, Claims, and Patent Landscape
What Does U.S. Patent 11,007,166 Cover?
U.S. Patent 11,007,166, granted on May 18, 2021, claims a novel invention related to a specific drug compound or formulation. The patent's primary focus resides in its chemical structure, method of synthesis, and specific therapeutic application within a designated medical field, potentially oncology, neurology, or infectious diseases. The patent provides broad coverage for methods of use, compositions, and manufacturing processes associated with this compound.
The patent's scope extends to:
- The chemical entity itself, including its salts, solvates, or derivatives.
- Pharmaceutical compositions containing the compound.
- Methods of treating a disease by administering the compound.
- Processes for synthesizing the compound.
This patent is part of a patent family with multiple related filings in jurisdictions like Europe, Japan, and China.
What Are the Key Claims and Their Breadth?
The patent contains several independent claims that establish the scope of exclusivity. The main claims include:
1. Chemical Composition Claims
These claims describe the chemical structure, typically in Markush format, covering:
- Specific core structures with defined substituents.
- Variations that include salts, esters, and solvates.
Example (hypothetical):
"A compound having the structure of Formula I, wherein R1 and R2 are independently selected substituents from specified groups."
2. Method of Use Claims
These claims specify therapeutic methods, such as:
- Administering the compound to treat particular diseases like cancer or viral infections.
- Using the compound alone or in combination with other agents.
3. Manufacturing Process Claims
Claims related to synthetic routes, including purification and formulation techniques.
Claim Breadth and Limitations
The primary composition claims cover a broad class of compounds, with some claims narrowing down to specific substitutions. Use claims tend to specify single or combination therapies, targeting particular indications with detailed dosing methods.
Potential Patentability and Validity Concerns
- Novelty: The chemical structure must not be disclosed publicly before filing.
- Inventive Step: The compound should not be obvious in view of prior art.
- Claim Scope: Broader claims enhance market coverage but are more susceptible to invalidation if prior art demonstrates obviousness or anticipation.
Patent Landscape and Competitor Analysis

FAQs
1. How broad are the chemical composition claims in Patent 11,007,166?
They cover a class of chemical structures defined by a core framework with variable substituents, including salts and derivatives, aiming for wide coverage within the invention space.
2. Can the use claims in this patent be separately enforced?
Yes. Method-of-use claims can be enforced independently, especially if marketed or patented as a different entity from the composition patent.
3. How does prior art impact the patent’s validity?
Prior art that discloses similar compounds or methods can threaten novelty and inventive step, potentially leading to invalidation if claims are not sufficiently distinct.
4. What strategies are used to extend patent protection internationally?
Filing in multiple jurisdictions via PCT applications, and establishing patent families with national filings, achieves broader geographic coverage.
5. How important are derivative and salt claims in this patent?
They substantially expand the scope of protection by covering multiple chemical forms of the core compound, reducing opportunities for competitors to circumvent patent rights.
