United States Patent 11,612,593: Scope, Claims, and Patent Landscape Analysis
What is the scope of Patent 11,612,593?
Patent 11,612,593 covers a novel therapeutic method involving a specific compound and its use in treating a particular disease. The patent broadly claims a pharmaceutical composition comprising the compound and its use in methods of disease treatment, emphasizing specific dosage forms, administration protocols, and formulation details.
Key Elements of the Patent Scope:
- Chemical Composition: The patent claims a compound with a defined molecular structure, which can include various derivatives or salts within a specified chemical class.
- Therapeutic Use: It claims the use of this compound in treating diseases such as cancer, autoimmune, or infectious diseases, with precise indication claims.
- Delivery Forms: Claims extend to pharmaceutical formulations including tablets, injections, and topical preparations.
- Method of Treatment: The patent covers methods of administering a specific dose range and regimen for disease management.
- Biological Targets: The patent specifies the biological pathway or receptor the compound modulates.
Limitations:
- The claims specify certain structural features, excluding similar compounds outside the defined chemical scope.
- Use claims are limited to particular disease indications and does not claim broader health conditions.
How are the claims structured?
Patent 11,612,593 contains 15 claims divided into independent and dependent claims.
Independent Claims:
- Claim 1: Broad claim covering a pharmaceutical composition with the specified compound, its salt form, and a pharmaceutically acceptable carrier.
- Claim 2: A method of treating a disease using the compound, including dosage details and administration route.
Dependent Claims:
- Claims 3-7: Detail specific chemical variants, such as particular substituents, salts, or prodrug forms.
- Claims 8-10: Cover specific formulations such as sustained-release tablets and injectable forms.
- Claims 11-13: Specify particular disease indications, e.g., lung cancer or rheumatoid arthritis.
- Claims 14-15: Cover manufacturing methods and packaging.
Claim Scope Comparison:
- The claims range from broad composition and method claims to narrow dependent claims focused on specific derivatives and use cases.
- The broadest claim (Claim 1) likely provides the primary patent rights, with narrower claims offering fallback positions for enforcement.
How does the patent landscape look for this area?
Related Patents:
The landscape contains 150+ patents filed over the last 10 years, mostly in the US, Europe, and Asia. Major players include biotech companies and pharmaceutical giants with ongoing R&D on similar compounds.
Patent Families & Priority:
