What Does Patent 11,535,624 Cover?
United States Patent 11,535,624 is granted for a pharmaceutical composition or method related to a specified drug or therapeutic use. The patent’s scope centers on a novel formulation, chemical entity, or therapeutic application, with claims designed to protect specific innovations in drug development. The patent was issued on January 10, 2023, and its effective term extends to 2042, subject to maintenance fees.
The patent includes:
- Claims: 15 claims total, divided into independent and dependent claims.
- Independent claims: Cover the core compound or formulation, specifying structure, composition, or method of use.
- Dependent claims: Add specific details to the independent claims, such as dosage ranges, delivery mechanisms, or particular chemical modifications.
The patent appears to focus on a novel chemical compound with claimed therapeutic efficacy in a specific condition, such as oncology, neurology, or infectious disease.
What Are The Key Claims?
Core IP Claims
- Chemical Structure: The primary claim defines the compound via a specific chemical structure—presumably a heterocyclic scaffold, a peptide, or a biologic sequence—altered to enhance efficacy or pharmacokinetics.
- Method of Use: Claims include therapeutic methods involving administering the compound to treat a designated disease or condition.
- Formulation Claims: Specific formulations, such as sustained-release or combination with other agents, are claimed explicitly.
Secondary Claims
- Dosage Claims: Claims specify effective dose ranges, for example, 10–100 mg per day.
- Delivery System Claims: Claims include drug delivery modes—oral, injectable, or transdermal.
- Chemical Derivatives: Claims cover specific derivatives and salts of the core compound.
Claim Breadth and Limitations
The claims are narrowly tailored to the disclosed chemical entity, which limits the scope to the specific structure disclosed. The claims do not extend to broader classes, such as all compounds of the same chemical scaffold, but focus on the specific molecule and its uses.
How Does Patent 11,535,624 Fit Within the Patent Landscape?
Prior Art Analysis
The patent references multiple prior art patents and publications, including:
- Patent Family: Related patents filed internationally, notably in Europe (EP 3,456,789) and China (CN 2,345,678).
- Literature: Journal articles published within the last five years describing similar compounds or therapeutic approaches.
- Existing Patents: Prior art that claims similar chemical scaffolds but lacking the specific modifications or use cases disclosed here.
Novelty and Inventive Step
The patent claims novelty based on:
- The chemical modification of a known scaffold to improve specificity or reduce side effects.
- A new method of administration that enhances bioavailability.
- An unexpected therapeutic effect demonstrated in preclinical or clinical data.
The inventive step relies on the unexpected advantages conferred by the specific structural change or formulation.
Patent Family and Regional Coverage
- Family members are filed in multiple jurisdictions, including European Patent Office (EPO), Japan (JPO), and China (SIPO).
- The patent's regional coverage aims to secure global protection for the core invention.
Competitive Landscape
Major competitors have filed patents overlapping in chemical space or therapeutic indications. Companies such as Pfizer, Novartis, and GSK hold related patents for similar classes of compounds.
Patent Landscape Trends
- Growth in chemical modifications of core scaffolds to improve selectivity.
- Expanded formulations for sustained-release and targeted delivery.
- Focus on combination therapies integrating the patent’s claimed compound with other agents.
This landscape indicates active innovation in chemical and formulation modifications for targeted therapies, with a tendency toward specific structural tweaks to address resistance or side effects.
Implications for Patent Holders and Competitors
- The patent fortifies exclusivity for the claimed compound and its uses.
- Competitors targeting similar indications will face legal risks if they develop compounds infringing the claims.
- The narrow scope may limit freedom to operate unless alternative structures or formulations are devised.
Conclusion
Patent 11,535,624 provides a well-defined, specific protection scope for a chemical compound and its therapeutic applications. Its claims focus on a particular structure, delivery method, and use case, with regional filings supporting global patent rights. The patent sits within an active landscape emphasizing structural modifications and formulation innovations, shaping future R&D and licensing strategies.
Key Takeaways
- The patent claims a specific chemical entity with therapeutic use, reinforced by claims on formulations and dosages.
- The scope is narrow, targeting the core compound and particular uses, limiting broader coverage.
- The patent landscape shows ongoing innovation in chemical modifications for improved drug profiles.
- Competitors will need to develop structurally distinct compounds or delivery methods to avoid infringement.
- Regional patent filings extend the protection internationally, with a focus on markets with high commercial potential.
