The patent's priority date aligns with the initial provisional application filed on August 25, 2019, which establishes its core timeline and priority rights.
Scope of Innovation
The patent claims encompass methods of modulating nucleic acid processing enzymes, notably RNA interference (RNAi) and CRISPR-based tools, for therapeutic applications. Its scope broadly covers:
- Use of specific small molecules, biologics, or nucleic acid modulators.
- Methods of administering such modulators.
- Therapeutic indications involving gene expression regulation, DNA repair, or epigenetic modifications.
The core contribution appears to be a novel combination or formulation of agents that enhance nucleic acid processing control, thereby offering refined treatment strategies for complex diseases.
Analysis of Key Claims
The patent comprises 12 claims, primarily divided into independent and dependent claims. Here are the salient aspects:
Claim 1 (Independent Claim):
- Core claim: A method of treating a disease characterized by aberrant nucleic acid processing, comprising administering an effective amount of a nucleic acid processing modulator, wherein the modulator is selected from a specific class of small molecules or biologics.
- Scope: This foundational claim sets the broadest protective boundaries, covering any modulator fitting the described class for the specified therapeutic purpose.
Claims 2–12 (Dependent Claims):
- Add particular features such as specific chemical structures, delivery methods, dosing regimens, or combinations with other therapeutics.
- Specify particular diseases, including cancer, viral infections, and genetic disorders.
- Claim 6 emphasizes a combination therapy involving a nucleic acid modulator and a chemotherapeutic agent.
Claim Language and Limitations:
- The claims are characterized by specificity in the type of modulators (e.g., small molecules with specific structural motifs) and target enzymes.
- The claims incorporate a method-of-use perspective, crucial for differentiating from composition or device patents.
Claim Scope Considerations:
- The claims are moderately broad, likely to cover a significant range of nucleic acid processing interventions.
- However, their scope depends heavily on the definitions of "modulator," "effective amount," and "disease," which are clarified in the detailed description.
