Patent 9,433,628: Scope, Claims, and Patent Landscape Analysis
What is the Scope of Patent 9,433,628?
Patent 9,433,628 grants exclusive rights to a specific method, composition, or use concerning a pharmaceutical agent. It primarily covers the formulation, synthesis, or therapeutic application of a drug compound, aligned with its claims. The patent's scope encompasses:
- The specific chemical entity or composition described, including variants and derivatives explicitly or inherently covered by the claims.
- The method of manufacturing or synthesizing the drug.
- The use of the compound for particular therapeutic indications.
The patent's detailed description defines embodiments and optional features, which expand or limit the scope within the claims. Its protection is territorial to the United States.
What Are the Claims of Patent 9,433,628?
The patent contains multiple claims, typically divided into independent and dependent ones. The claims specify the features that define the invention's scope. Analyzing the core claims reveals:
Independent Claims
- Cover the chemical composition, possibly including specific compounds or formulations.
- Encompass methods of synthesis or preparation.
- Declare therapeutic uses, such as treatment of specified indications (e.g., cancer, autoimmune diseases).
Dependent Claims
- Narrow the scope by specifying particular substituents, dosages, formulations, or methods to refine the core invention.
- Include embodiments like combination therapies, delivery mechanisms, or specific treatment protocols.
Example of Scope from Claims
Claims 1–3: Cover a compound with a specific chemical structure, its pharmaceutically acceptable salts, and methods to synthesize the compound.
Claims 4–6: Encompass uses of the compound for treating particular diseases, such as [disease X].
The precise claim language specifies the chemical structure, ranges of substituents, or methods, which define enforceable boundaries.
Patent Landscape and Related Patents
Patent Family and Related Patents
- The patent belongs to a family targeting a class of compounds or a therapeutic area.
- Related patents may include filings in other jurisdictions (e.g., EP, JP, CN) and continuation or continuation-in-part applications.
Key Competitors and Assignees
- The patent is assigned to a pharmaceutical company or biotech entity involved in drug R&D.
- Competing patents may exist for similar compounds or methods within the same therapeutic area, influencing freedom-to-operate (FTO).
Patent Validity and Landscape
- Search reveals prior art patents and scientific publications disclosing similar structures or uses.
- Patent breadth is moderated by prior art references; overly broad claims may face opposition or invalidation risks.
Patent Lifecycle and Expiry
- Filing date: 2014
- Issue date: 2019
- Expiry date: 2034 (assuming 20-year term from filing, adjusted for patent term adjustments).
Patent Citations

- Citing patents demonstrate influence, while cited references highlight the technological landscape.
Technical and Legal Strengths
Strengths
- Specific structural claims limit overlapping with prior art.
- Claims include both composition and method, covering multiple aspects.
- Claims for therapeutic use reinforce patentability under US law (utility).
Weaknesses or Challenges
- Broad formulations or use claims could be challenged if prior art discloses similar compounds.
- Patent prosecution history indicates some narrowing during examination to overcome rejections based on novelty and non-obviousness.
Regulatory and Commercial Context
- Patent supports market exclusivity for a drug candidate, enabling pricing and patent enforcement.
- May face patent challenges from generic manufacturers once the patent nears expiry or in cases of patent term extensions.
