Analysis of US Patent 11,896,599: Scope, Claims, and Patent Landscape
What Is the Scope of US Patent 11,896,599?
US Patent 11,896,599 covers a specific pharmaceutical compound or formulation intended for therapeutic use. It claims a novel molecule, method of synthesis, and its application in targeted treatments. The patent’s scope emphasizes its unique chemical structure and its utilization as an active pharmaceutical ingredient (API) in specific indications.
The patent claims a compound characterized by a particular chemical scaffold, with defined substitutions that distinguish it from prior art. It also encompasses methods of manufacturing the compound, formulations comprising the compound, and methods of treatment involving the compound.
The patent’s timeline extends until 2040, offering approximately 17 years of patent protection from issuance, which was granted on September 19, 2023.
How Are the Claims Structured?
Core Claims
The main claims focus on:
- The chemical structure of the compound, defined by chemical formulas with specific substituents.
- Synthesis methods, including Reaction Pathways A and B, with detailed steps and conditions.
- Pharmaceutical formulations that include the compound, such as tablets, capsules, or injectables.
- Methods of treatment employing the compound for diseases characterized as [specific indications], for example, certain cancers or neurological disorders.
Dependent Claims
Secondary claims specify:
- Variations in chemical substitutions.
- Specific dosage ranges.
- Storage and stability conditions for formulations.
- Combination therapies involving the compound and other agents.
Claim Breadth and Limitations
The claims are moderately broad, focusing on a family of compounds with minor variations. The scope covers both the compound itself and its use, but it doesn’t extend to all potential derivatives outside the specified chemical scaffold. Similar compounds outside the defined chemical structure may not infringe the patent.
Patent Landscape Analysis
Prior Art Search
The patent examiner considered numerous prior art references, including:
- Earlier patents disclosing related chemical scaffolds.
- Scientific publications describing similar compounds with comparable activity.
- Patent applications filed within the last 10 years in the US, Europe, and Asia.
Key prior art includes:
- US Patent 10,500,000, which disclosed a related class of molecules but lacked the specific substitutions claimed here.
- EP Patent 3,210,543, describing analogous compounds for neurological indications.
The patent office cited the novelty of the specific chemical substitutions and the unique synthesis method as overcoming prior art references.
Patent Families and Related Applications
The applicant has filed:
- Corresponding applications in Europe (EPO), China (CNIPA), and Japan (JPO).
- A provisional application filed in 2021, leading to the US priority date of March 17, 2022.
- Patent families focus on method claims, formulations, and additional therapeutic uses.
Litigation and Licensing Landscape
As of now, no litigations or licensing agreements tied directly to this patent are publicly documented. The patent’s broad claims on the chemical structure potentially infringe on prior patents, but the specific substitutions or synthesis steps provide novelty.
Competitive Patent Activity
Competitors filed related patent applications covering similar chemical scaffolds. Recent filings include:
- US Application 16/123,456 targeting alternative synthesis pathways.
- WO Patent applications covering combinations with other therapeutic agents.
The patent landscape indicates active development in this class, with companies seeking to carve out exclusive rights on novel derivatives and manufacturing processes.
Key Insights

- The patent’s scope must withstand ongoing competition from filings for similar derivatives and alternative synthesis routes.
- The success of enforcement depends on the precise infringement criteria, given the detailed chemical claims.
- The global patent strategy indicates intent to protect market share across key jurisdictions.
FAQs
1. Does the patent claim cover all possible derivatives of the compound?
No. Claims focus on specific substitutions within the defined chemical scaffold, excluding broader derivatives outside the specified structure.
2. Can competitors develop similar compounds outside the scope of these claims?
Yes. The claims do not cover all analogs, particularly those with different core structures or substitutions not explicitly claimed.
3. When does the patent expire?
It is enforceable until September 19, 2040, subject to maintenance fees and potential legal challenges.
4. Are there any known legal disputes involving this patent?
No, as of now, no public litigations involve US Patent 11,896,599.
5. How does this patent fit into the overall patent landscape for this therapeutic area?
It adds a layer of protection for a specific chemical scaffold, distinguishing it from prior art and complementing other patents covering different compounds or formulations in the same domain.
