Analysis of Scope, Claims, and Patent Landscape for US Patent 9,474,722
What is the Scope of US Patent 9,474,722?
US Patent 9,474,722 covers a pharmaceutical invention related to a specific drug compound, formulation, or method of use. The patent's scope hinges on its claims, which define the legal boundaries of the invention. The patent was granted on October 25, 2016, and the assignee is often a pharmaceutical company or research entity.
The patent encompasses claims directed toward:
- A specific chemical compound or class of compounds.
- Pharmaceutical compositions containing the compound.
- Methods of treating certain conditions or diseases using the compound.
The scope varies based on whether the claims are narrow (specific compounds or uses) or broad (covering multiple variants or methods). The patent's claims extend to:
- Chemical structure claims, including derivatives or salts.
- Pharmaceutical formulations (e.g., tablets, injections).
- Methods of treatment, including dosage regimes and administration routes.
What are the Main Claims?
An in-depth review of the claims reveals whether they are independent or dependent:
Independent Claims:
- Typically claim a key chemical compound with defined structural features.
- Cover a pharmaceutical composition comprising the compound.
- Describe a method of treatment involving administering the compound to a patient.
Dependent Claims:
- Add specific limitations or particular embodiments.
- Specify particular substituents, salts, or crystal forms.
- Cover specific formulations, doses, or treatment methods.
Example (hypothetical):
- Claim 1: A compound of formula I, where R1 and R2 are defined substituents, with pharmacological activity against a particular target.
- Claim 2: The compound of claim 1, further comprising a pharmaceutically acceptable salt.
- Claim 3: A pharmaceutical formulation comprising the compound of claim 1.
- Claim 4: A method of treating condition X by administering an effective amount of the compound of claim 1.
The breadth of these claims determines enforcement scope and infringement risks.
Patent Landscape Context

FAQs
Q1: Can the patent claims be challenged based on prior art?
A1: Yes, prior art searches in chemical and pharmaceutical databases could identify references challenging novelty or non-obviousness, potentially leading to patent invalidation.
Q2: Does the patent cover all chemical variants of the compound?
A2: Only those within the scope of the claims, which specify certain structural features. Salts, formulations, and methods are also included if covered by dependent claims.
Q3: Are methods of manufacturing included in the patent?
A3: Typically, unless specifically claimed, manufacturing methods are not covered. Analyzing the claims reveals whether production processes are protected.
Q4: How does the patent landscape affect generic entry?
A4: The scope and duration of patent protection inform the timeline for generic competitors, generally post-2034 barring challenges or patent extensions.
Q5: Can licensing be pursued for commercialization?
A5: Licensing agreements typically involve negotiations with the patent owner, who controls the rights within the patent's scope and territories.
