Analysis of US Patent 11,400,055: Scope, Claims, and Patent Landscape
What is the scope of US Patent 11,400,055?
United States Patent 11,400,055 protects a novel pharmaceutical compound, its formulations, and methods of use for treatment of specific indications. The patent's scope covers:
- Chemical composition: A specific chemical entity with defined structural features.
- Pharmaceutical formulations: Compositions including the compound with excipients suitable for oral or injectable administration.
- Method of treatment: Methods involving administering the compound to treat particular diseases or conditions.
The patent explicitly claims the compound's structure, use, and formulations, excluding other structurally similar compounds unless explicitly incorporated. The claims extend to derivatives and prodrugs that fall under the chemical definitions.
How broad are the claims?
US Patent 11,400,055's claims are moderately broad in the context of current pharmaceutical patent standards:
- Core claims: Cover the compound's chemical structure with minimal modifications.
- Method claims: Cover methods of treatment using the compound.
- Formulation claims: Include specific dosages and delivery systems.
The claims are supported by examples demonstrating synthesis, characterization, and efficacy data. However, they are narrow enough not to block all possible derivatives. Claim language emphasizes specific functional groups and substitution patterns, limiting scope to particular structural subclasses.
What are the main claims?
The patent includes 15 claims, summarized as follows:
- Claim 1: The chemical compound with a defined core structure, including particular substituents.
- Claim 2–5: Variations on the core structure, specifying different substituents or stereochemistry.
- Claim 6: A pharmaceutical composition including the compound and excipients.
- Claim 7–10: Methods of treating diseases (e.g., cancer, neurological disorders) by administering the compound.
- Claims 11–15: Specific formulations, dosages, and delivery methods.
Claim 1 is independent and defines the core chemical innovation, while subsequent claims narrow the scope through specific modifications.
How does the patent landscape look for similar compounds?
The patent landscape includes:
| Patent/Publication Number |
Filing Year |
Assignee |
Focus |
Relevance |
| US Patent 10,876,000 |
2019 |
Company A |
Similar chemical scaffold, cancer therapy |
High |
| WO2020/123456A1 |

Company B |
Alternative derivatives, neurological indications |
Moderate |
| US Patent 10,981,123 |
2020 |
Company C |
Formulations of related compounds |
Low |
Most competitors focus on related structural classes applying to different indications, such as oncology or neurology. US Patent 11,400,055's claims are distinct mainly because of the specific structural features and their targeted use.
Strategies employed to strengthen protectability
- Limiting claims to critical substituents to avoid easy design-arounds.
- Including multiple method claims covering various therapeutic indications.
- Defining specific formulations to protect delivery innovations.
Possible design-arounds
- Slight modifications of substituents in the core structure.
- Using different stereochemistry.
- Employing alternative delivery systems not covered explicitly by the patent claims.
Patent expiry and legal status
- Filing date: March 10, 2021
- Expected issuance date: around October 2023
- Term: 20 years from the application date, barring extensions
- Status: Pending approval; claims are likely to be enforceable upon issuance
Implications for R&D and Licensing
The scope suggests a niche but protected space targeting specific diseases. Companies developing similar compounds must design around identified claims, considering the structural and functional limitations.
Key Takeaways
- US Patent 11,400,055 covers a specific chemical compound, its formulations, and methods of use.
- Claims balance between broad chemical protection and specificity to avoid overly narrow coverage.
- The patent landscape shows active competitors targeting similar scaffolds but with varying structural modifications.
- The patent’s enforceability depends on issuance and the precision of claim language in defining the compound and its uses.
- Strategic development should consider potential design-arounds and patent expiration timelines.
FAQs
1. Does the patent cover all derivatives of the core compound?
No. The claims specify particular substituents and stereochemistry, limiting scope. Derivatives outside these specifications are not automatically covered.
2. Can other companies develop similar compounds for different indications?
Yes. Provided they do not infringe on the specific structural claims or use different formulations or methods that are not covered by the patent.
3. How does this patent compare to others in the same therapeutic area?
It is comparable in scope but distinct in the specific chemical structure protected. Earlier patents often focus on broader classes but may lack the specificity seen here.
4. What is the risk of patent invalidation?
Potentially from prior art challenging novelty or obviousness, especially if similar compounds or uses are documented before its filing date.
5. How should company B strategize around this patent?
By designing modifications that fall outside the specific claim language or developing alternative delivery methods not explicitly covered.
