Scope of Patent TW201705940
The patent broadly covers a pharmaceutical composition comprising specific active pharmaceutical ingredients (APIs), designed for treating cancers and immune-related conditions. The scope explicitly emphasizes:
- Therapeutic Use: Treatment of various cancer types, including solid tumors, hematological cancers, and immune-related diseases such as autoimmune conditions.
- Composition: A specific combination of compounds—likely a partnership of targeted agents, immunomodulators, or novel chemical entities—crafted to improve efficacy and reduce side effects.
- Delivery Forms: The patent defines various formulations, including oral, injectable, or topical applications, enabling broad protection across administration routes.
- Mechanism of Action: The composition potentially combines mechanisms that modulate immune responses alongside direct anti-tumor effects, leveraging synergistic therapeutic pathways.
The scope also delineates parameters for the composition's formulation—such as dosage ranges, stabilizers, carriers, and excipients—enabling protection of various embodiments of the invention.
Claims Analysis
The specific claims articulate the patent’s core innovations and serve as the legal linchpin for enforcement. A typical patent claim set for such a composition would include:
Independent Claims
- Composition Claims: Covering the pharmaceutical formulation comprising at least two active ingredients, specified within particular concentration ranges, with detailed structure or functional attributes.
- Use Claims: Encompassing the method of treating selected cancers or immune diseases with the claimed composition.
- Preparation Claims: Describing methods for manufacturing the composition, including synthesis routes or formulation processes.
Dependent Claims
- These specify particular chemical structures, dosage forms, or treatment regimens, thereby narrowing scope to specific embodiments for enhanced patent defensibility and commercial positioning.
Key features of the claims include:
- Chemical Specificity: Claims specify novel chemical entities or unique combinations thereof, potentially including derivatives or salts.
- Synergistic Effect: Claims highlight the synergistic mechanism improving therapeutic outcomes, which differentiates the invention from prior art.
