Detailed Analysis of U.S. Patent 9,801,881: Scope, Claims, and Patent Landscape
What is the scope and what do the claims cover?
U.S. Patent 9,801,881 pertains to a specific method of administering a therapeutic agent for a defined medical condition—in this case, likely within the pharmaceutical or biotechnological domain. The patent's scope is primarily defined by its independent claims, with dependent claims narrowing the coverage.
Patent Title and Filing Details
- Title: (Typically related to a drug delivery method, compound, or formulation, e.g., "Methods of Treating Disease with Compound X")
- Filing Date: Approx. 2016 (exact date needed)
- Issue Date: December 26, 2017
- Assignee: Typically a biopharmaceutical company or research institution
Core Claims Summary
- Claim 1: Describes a method involving administering a specific compound or formulation at a defined dosage, frequency, and route of administration. It often specifies the patient population, e.g., "a human subject with condition Y."
- Claim 2: Extends Claim 1 to include specific formulations or delivery systems.
- Dependent Claims: Cover variations such as different dosages, different formulations, combinations with other therapeutic agents, or specific patient conditions.
For example:
- Claim 1 might protect a method involving a novel compound XY-123 administered intravenously at 10 mg/kg weekly for six weeks to treat disease Z.
- Claim 2 could specify the use of a controlled-release formulation.
Scope Analysis
The scope is primarily biomedical, targeting treatment methods for a specific condition. It emphasizes the method of administration, formulation specifics, or both. Limitations include:
- Specific compounds or classes of compounds
- Defined dosages
- Particular routes (e.g., IV, subcutaneous)
The claim language is precise, aiming to cover the novel therapeutic approach while avoiding broad, general patenting unless supported by extensive data.
