How Does the Claim Language Define the Patent's Scope?
Key Elements of the Claims
- Amino Acid Sequence Patterns: Typically, claims specify sequences with certain conserved motifs, e.g., "a peptide comprising an amino acid sequence having at least 80% identity to SEQ ID NO:1."
- Functional Attributes: The peptides are characterized by their ability to bind specific immune receptors (e.g., T-cell receptors, Toll-like receptors).
- Administration Protocols: Claims include methods of administration—dose, frequency, route—to achieve immune modulation.
- Therapeutic Indications: Target conditions like multiple sclerosis, rheumatoid arthritis, and transplant rejection.
Claim Scope Connotations
- The focus on specific sequences confers narrowness, defending against broad competitor innovations.
- Functional claims based on activity provide broader protection but can be challenged by prior art demonstrating similar activity with different sequences or mechanisms.
- Combination claims increase scope but may face validity challenges if the underlying components are known.

Frequently Asked Questions (FAQs)
1. How does the scope of the '572 patent compare to other immune-modulating peptides?
The '572 patent’s claims are sequence-specific, providing narrower scope compared to broader activity-based patents. However, they benefit from precision, reducing the likelihood of invalidity, particularly if technological advancements allow modifications around its claims.
2. Can a competitor design a peptide that avoids infringing on the '572 patent?
Yes. Slight alterations to amino acid sequences, such as amino acid substitutions that do not compromise activity, can potentially avoid infringement, especially if supported by evidence demonstrating the modified peptide's efficacy.
3. What are the implications of patent expiration or maintenance lapses?
Expiration or lapse of the '572 patent would permit competitors to develop and market peptides with similar sequences for immune modulation. Monitoring such events influences R&D and licensing decisions.
4. How does the patent landscape impact licensing opportunities?
The concentration of patents related to peptide sequences and immune modulation suggests potential licensing avenues for entities seeking to develop similar therapeutic agents, especially if claims overlap.
5. Are there ongoing patent prosecutions or oppositions that could affect the '572 patent?
While there are no publicly filed oppositions as of 2023, ongoing patent applications attempting to carve around the '572 patent may influence its enforceability and scope.
