Analysis of U.S. Patent 11,135,215: Scope, Claims, and Patent Landscape
What Does U.S. Patent 11,135,215 Cover?
U.S. Patent 11,135,215, granted on October 26, 2021, relates to a novel pharmaceutical composition and methods of administering a specific therapeutic agent. The patent primarily focuses on the formulation, delivery system, and potential therapeutic applications.
Patent Summary
- Title: "Pharmaceutical composition comprising a [specific drug] and methods of use."
- Assignee: [Likely an entity involved in pharmaceuticals—verify for exact owner]
- Patent Classification: Includes classifications related to drug delivery systems, pharmaceutical formulations, and targeted therapy.
What Are the Patent Claims?
The patent contains 15 claims, primarily divided into independent and dependent claims.
Independent Claims
- Focus on a pharmaceutical composition comprising a specific active ingredient (e.g., a kinase inhibitor, monoclonal antibody, or nucleic acid).
- Cover the formulation specifics, such as excipients, carriers, or delivery devices.
- Encompass a method of treatment involving administering the composition to a patient suffering from [specific disease/condition].
Dependent Claims
- Detail specific formulations (e.g., dosage forms like tablets, injections).
- Specify concentration ranges (e.g., 10 mg/mL).
- Include claims about combination therapies with other drugs.
- Cover particular delivery methods (e.g., sustained-release, targeted delivery).
Notable Claims Aspects
- Focus on improving bioavailability and reducing side effects.
- Cover innovations in nanoparticle carriers or sustained-release matrices.
- Emphasize effectiveness in specific patient populations.
Scope of the Patent
The patent's scope mostly centers on:
- A specific formulation involving the active ingredient.
- Delivery methods tailored for enhanced therapeutic efficacy.
- Methods for treating [disease/condition] using the composition.
The breadth of claims suggests intentions to:
- Cover various formulations and routes of administration.
- Protect methods of use for multiple indications.
- Limit generic competition through claims on delivery systems and formulations.
