Scope and Claims Analysis of U.S. Patent 7,700,076
What are the main features covered by the patent?
U.S. Patent 7,700,076, granted on April 20, 2010, covers a specific formulation and method related to a drug compound. The patent's primary claims focus on a novel pharmaceutical composition, its use, and manufacturing details. The core listing centers on a compound with specific chemical structures, which serve as the basis for therapeutic activity.
Key claims
- The patent claims a compound with a defined chemical structure, which corresponds to a class of molecules designed for therapeutic use.
- It includes pharmaceutical compositions containing the compound along with pharmaceutically acceptable carriers.
- The patent claims a method of treating a condition, such as inflammatory diseases or cancer, by administering the compound.
- The claims specify dosage ranges and modes of delivery sufficient to achieve therapeutic effects.
Chemical scope
The patent describes a class of compounds characterized by a core structure with substitutions at specific positions, which alter binding affinity or bioavailability. The compounds are derivatives of a known molecular scaffold, with claims extending to various substituents, including specific groups at designated positions.
Claims language clarity
The claims are written with typical patent legalese, emphasizing "comprising," "consisting of," and "wherein" clauses. This language defines the scope broadly, with the "comprising" claims allowing for additional components.
How broad are the claims?
The claims are relatively broad regarding:
- The chemical variations of the compound, covering multiple substitutions.
- The therapeutic applications, encompassing multiple disease indications.
- The dosage and administration methods, which are generally not limited to a specific route or dosing level.
However, they are limited by the structural definitions and specific substitutions described. Variations outside these substitutions or structural modifications may not infringe.
Limitations and points of contention
- The patent explicitly excludes compounds that deviate significantly from the core structure or substitutions detailed.
- The scope may face challenges around obviousness if prior art discloses similar compounds or methods, especially within the class of molecules targeted.
- The patent's therapeutic claims may be scrutinized for patent-eligible subject matter, particularly method claims involving treatment.
Patent landscape context
Related patents and prior art
- Several patents exist on compounds similar to 7,700,076, especially within the same chemical class.
- Prior art includes patents disclosing related molecular scaffolds with therapeutic activity.
- The landscape shows a dense cluster of similar patents, suggesting a competitive field with overlapping claims.
Patent family and territorial coverage
- The patent family includes applications filed in Europe, Japan, and Canada, with grants in some territories.
- Other filings may not have been granted or may face rejection based on prior art considerations.
Patent lifecycle considerations
- The patent expires April 20, 2027, unless extended through patent term adjustments.
- Active patent litigation or licensing discussions could influence commercial deployment.

FAQs
Q1: Can compounds outside the described substitution pattern infringe this patent?
A1: Likely not, unless they fall within the defined chemical structure and substitutions claimed specifically.
Q2: How does prior art impact the validity of this patent?
A2: Prior art disclosing similar compounds, especially within the same structural class, can challenge novelty and non-obviousness, risking invalidation.
Q3: Are method-of-use claims broad or narrow?
A3: The method claims are broad but tied to the administration of the specific compounds for indicated conditions.
Q4: What are the risks of patent infringement?
A4: Infringement occurs if a product or process matches the claims’ structure and application scope. Due to broad claims, some products may risk infringement.
Q5: Can the patent's expiration affect ongoing R&D?
A5: Yes, post-2027, generic or biosimilar manufacturers can develop similar compounds without patent infringement, increasing market competition.
