Scope and Claims
Patent Abstract and Core Innovation
WO2018130723 introduces methods for modulating immune responses through compositions involving specific biological agents—primarily, peptides, antibodies, or nucleic acid constructs targeting immune regulators. The patent emphasizes selective modulation to enhance immune activity against malignancies or pathogens while minimizing adverse autoimmune responses.
Claim Structure Analysis
The patent's claims focus primarily on:
- Method of Treatment: Claims encompass administering specific biologic agents—such as antibodies targeting immune checkpoint molecules (e.g., PD-1, CTLA-4)—designed to modulate immune responses in cancer or infectious disease contexts.
- Composition Claims: Patent protection extends to pharmaceutical compositions comprising these biologic agents, possibly combined with adjuvants or delivery vectors.
- Biomarker-Linked Approaches: Claims specify identifying patient biomarkers indicative of immune status, optimizing personalized therapy.
- Manufacturing and Delivery: Claims cover methods of producing and delivering these agents to achieve targeted immune modulation.
Key aspects of the claims include:
- Specificity: The claims specify particular epitopes on immune checkpoint molecules, antibody variants, or nucleic acid sequences that encode functional modulators.
- Dosing Regimens: Several claims delineate dosage schedules optimizing therapeutic windows.
- Combination Therapies: Claims extend to combination with other immuno-oncology drugs or traditional chemotherapies.
Scope Limitations
While the claims are precise—focusing on certain biologic agents and therapeutic methods—they are sufficiently broad to encompass various embodiments of immune modulation. This breadth aims to prevent workarounds and to cover multiple therapeutic modalities within the scope of immune response regulation.
