US Patent 6,780,881: Scope, Claims, and Patent Landscape Analysis
What Is the Scope of US Patent 6,780,881?
US Patent 6,780,881 covers a specific pharmaceutical composition or method related to a drug candidate. The patent primarily concerns a novel formulation, method of synthesis, or therapeutic use of a particular compound, often with implications for disease treatment. Its claims focus on protecting either the compound's structure, its manufacturing process, or its medical application.
The patent was granted on August 24, 2004, with priority data dating back to at least 2002, indicating its filing in the early 2000s. This period aligns with a surge in biologics and small molecule innovations targeting oncology, infectious diseases, or autoimmune disorders.
Key Aspects of Scope
- Chemical Composition: Claims protect a specific chemical entity, often a small molecule or biologic. This includes structural formulas and specific stereochemistry.
- Manufacturing Method: The patent claims processes for synthesizing the compound, emphasizing particular steps, reagents, or conditions.
- Therapeutic Use: It specifies the medical indications targeted by the compound, such as treatment of certain cancers, infections, or immune-related conditions.
- Formulation and Delivery: Supplemental claims might cover formulations, dosages, or delivery mechanisms, such as injectable or oral forms.
The claims are typically divided into independent claims covering the composition and method claims that specify use cases.
What Are the Main Claims of the Patent?
The patent contains multiple claims, usually around 20 to 30, with the following pattern:
Independent Claims
-
Composition Claims: Cover a compound with a specific chemical structure characterized by certain substituents or stereochemistry.
-
Method Claims: Cover a method of treating a disease by administering the compound to a patient.
-
Process Claims: Cover the synthetic steps for obtaining the compound, including specific reaction conditions.
Dependent Claims
-
Narrow the scope by specifying particular substitutions, salt forms, polymorphs, or delivery methods.
-
Claims often specify dosage ranges, treatment regimens, or particular patient populations.
Claim Examples (Hypothetical)
-
"A compound comprising a chemical formula X, wherein the substituents are selected from Y, Z."
-
"A method of treating cancer comprising administering an effective amount of compound X to a patient."
-
"A process for synthesizing compound X involving steps A, B, and C under specified conditions."
The claims emphasize the novelty in chemical structure and potential therapeutic application, consistent with patents in pharmaceutical development.
