Example:
Claim 1 (hypothetical) might specify a compound with a particular heterocyclic core, a specific substitution pattern, and its use in treating a defined disease. Claim 2 might narrow to a specific salt form or dosage regimen.
Key Claim Elements
- Chemical Definitions: The core chemical structure often includes a heteroaromatic ring, multiple substituents, or stereochemistry.
- Method of Use: The patent can claim methods of administering, synthesizing, or diagnosing using these compounds.
- Formulation & Composition: Claims may encompass specific pharmaceutical formulations, including excipients or delivery methods.
- Therapeutic Application: Disease or condition-specific claims—e.g., treatment of schizophrenia, depression, or metabolic syndromes.
How Broad Is the Patent’s Claim Coverage?
Claim breadth influences enforceability, freedom-to-operate assessments, and licensing.
| Aspect |
Assessment |
Implication |
| Chemical Scope |
Likely narrow if claims define specific chemical structures or substitutions |
Limits infringement to compounds explicitly claimed |
| Use Claims |
Can be broad if encompass a wide therapeutic indication |
Could allow broader licensing opportunities |
| Method Claims |
Often narrower, focusing on specific synthesis or administration steps |
More vulnerable to design-arounds |
Observation:
The patent's breadth depends on whether it claims generic chemical classes or specific molecules. Recent patent trends favor narrow claims due to patentability challenges, yet broad claims may offer greater market exclusivity.

Claim Construction and Potential Challenges
Claim Construction Strategy
Scope interpretation involves analyzing the patent's detailed description, drawings, and patent doctrine. The claims are interpreted in view of the specification, prior art, and prosecution history.
Key Challenges and Validity Risks
- Obviousness: The claims could be challenged if prior art discloses similar compounds or methods.
- Lack of Enablement: Questions may arise if the patent does not sufficiently describe how to synthesize or use the claimed invention.
- Anticipation: Prior patents or publications with matching disclosures threaten novelty.
Notable Litigation & Litigation Risks
While specific litigation references to US patent 7,799,777 are scarce publicly, similar patents faced generic challenges around obviousness, especially over references published before the patent’s priority date.

Frequently Asked Questions (FAQs)
Q1: Can this patent be infringed if a competitor develops a similar compound with slight modifications?
A: Infringement depends on claim scope. If modifications fall within patent claims' literal language or equivalents, infringement can occur. Narrow claims limit this risk.
Q2: How does the patent landscape around US 7,799,777 influence market entry?
A: The landscape’s richness in overlapping patents may restrict market entry, require licensing, or prompt development of non-infringing alternatives.
Q3: Are there any notable legal challenges or litigations connected to this patent?
A: Public records do not indicate major litigations specifically targeting this patent; however, challenges common in biotech may include validity or infringement suits.
Q4: Is there potential for patent term extension or additional protection beyond 2026?
A: If supplementary data or patents relate to pediatric extensions or supplementary protection certificates, additional protections are possible within applicable jurisdictions.
Q5: What are the key considerations when designing around this patent?
A: Focus on chemical modifications outside the scope of the claims, alternative formulations, or different therapeutic targets that do not infringe the specific claim language.
