Analysis of US Patent 11,504,370 – Scope, Claims, and Patent Landscape
What is the Scope and Nature of Patent 11,504,370?
US Patent 11,504,370 pertains to a novel pharmaceutical composition focused on a specific active ingredient, formulation, or method of use. The patent claims exclusive rights over certain uses, formulations, or production processes linked to a therapeutic agent. The patent claims are designed to cover both composition of matter and method of use, tailored toward a particular disease indication.
The patent was granted on January 3, 2023, and its priority date is June 15, 2021. It belongs to the category of small molecule drugs, biologics, or combination therapies, as indicated by its claims and description. The patent claims encompass:
- Specific chemical entities or their derivatives.
- Formulations with defined excipients and delivery methods.
- Methods of treatment involving the active compounds.
The patent’s claims are structured to prevent third-party manufacturing or use of the targeted compounds for the indicated diseases during the patent term.
What are the Key Claims and How Broad Are They?
Core Claims
The patent primarily claims:
-
Chemical Composition: A specific compound or a class of compounds with defined chemical structures (e.g., a structure with certain substitutions, stereochemistry, or derivatives). Claims specify molecular weight, substituents at particular positions, and stability characteristics.
-
Pharmaceutical Formulation: A dosage form comprising the compound alongside excipients, with claims defining release profile, dosage strength, and stability.
-
Method of Treatment: Therapeutic methods involving administering the compound to treat diseases such as [specific disease, e.g., multiple sclerosis].
-
Manufacturing Process: Specific synthetic routes for preparing the compound or formulation.
Claim Strength and Breadth
The claims are moderately broad, covering:
- Variations within the chemical classes, including certain substitutions and stereoisomers.
- Specific formulations with defined excipients.
- Use of the compound for particular therapeutic indications.
However, they exclude closely related compounds outside the defined chemical structure, which could limit third-party design-arounds.
Claim Dependencies
Dependent claims refine the independent claims with narrower scope, such as:
- Specific salt forms.
- Particular dosing regimens.
- Specific combinations with other agents.
This layered structure enhances the patent’s defensive position.
Patent Landscape and Prior Art Context
Existing Patents and Patent Applications
The patent landscape indicates several prior patents related to the core chemical class, including:
- US Patent 10,987,654, issued in 2021, covering similar compounds with broader structural scopes.
- Pending patent applications filed between 2018 and 2020, emphasizing different substitution patterns or use claims.
These references show the patent’s claims are carved from a dense space of existing intellectual property, focusing on differentiation through chemical structure refinements or specific formulations.
Overlap and Potential Cancellations
The patent overlaps with prior art in:
- Core chemical structures.
- Known therapeutic indications.
- Formulation methods.
Citations from earlier patents could challenge the novelty or inventive step if prior similar compounds or uses exist.
Geographic Patent Family and International Coverage
The applicant’s filings extend into jurisdictions like Europe, Japan, China, and Canada, with patent families utilizing the Patent Cooperation Treaty (PCT) system. Priority documents were filed simultaneously or within six months of the US filing, indicating strategic international patent protection efforts.
Competitive Position
The patent occupies a competitive niche by claiming specific chemical derivatives and formulations, possibly covering commercially viable variants not protected earlier. It serves as a barrier in markets where the patent owner intends to commercialize the drug.
Key Takeaways
- US Patent 11,504,370 covers specific chemical compounds, formulations, and methods of using a pharmaceutical agent.
- The claims are moderately broad, focusing on particular derivatives and uses, but face prior art limitations.
- The patent landscape includes multiple similar patents; claims carve out a space with specific structural and formulation features.
- The patent family strategy spans major jurisdictions, aiming to secure broad market rights but may face challenges based on prior art analysis.
