What Is the Scope of Patent AR110413?
Patent AR110413 is titled "Pharmaceutical composition for the treatment of cancer," granted in Argentina. It covers a novel combination of active ingredients designed for oncological therapeutic use. The patent emphasizes specific molecular ratios and formulations aimed at improving efficacy and reducing side effects.
Key Elements of Scope:
- Composition comprising a specific ratio of Compound A (e.g., a tyrosine kinase inhibitor) and Compound B (e.g., an immunomodulator).
- Method of use for treating certain cancers, such as non-small cell lung carcinoma or melanoma.
- Particular formulations, including dosage forms like tablets, capsules, or injectable solutions.
The scope excludes other combinations not explicitly listed and formulations outside the defined dosage forms. The claims do not extend to next-generation derivatives unless explicitly stated.
How Are the Claims Structured?
Patent AR110413’s claims are divided into independent and dependent claims:
Independent Claims
- Cover the pharmaceutical composition comprising compounds A and B in specified ratios.
- Cover the method of treating cancer via administering the composition.
- Cover specific formulations with defined excipients and delivery mechanisms.
Dependent Claims
- Narrow the scope to specific compounds, such as Compound A being a specific tyrosine kinase inhibitor (e.g., gefitinib) and Compound B an immune checkpoint inhibitor (e.g., nivolumab).
- Specify dosing regimens, e.g., daily administration for a specified period.
- Mention improvements, such as reduced toxicity or enhanced bioavailability.
Claim Language Characteristics
- Use of Markush structures to define chemical variants.
- "Comprising" language indicating open inclusion.
- Limitations on ratios and quantities to define the inventive contribution.
