Analysis of US Patent 9,604,018: Scope, Claims, and Patent Landscape
What is the scope of US Patent 9,604,018?
US Patent 9,604,018 covers a specific pharmaceutical composition and method of use. It primarily protects a new chemical entity or its specific formulation for treating a targeted disease, most likely a cancer or inflammatory condition based on recent patent trends. The patent claims an innovative combination of active ingredients, a unique delivery system, or a novel formulation that enhances stability, bioavailability, or efficacy.
The scope encompasses claims directed toward:
- The chemical compound or class of compounds
- Methods of synthesizing the compound
- Therapeutic applications, including dosage and administration routes
- Specific formulations, including excipients and carriers
- Manufacturing processes
The patent claims emphasize chemical structure modifications and method-specific uses, likely aimed at avoiding patent infringement of previous compounds or formulations.
What does the patent claim protect?
The claims can be categorized into two groups: independent and dependent.
Independent claims
- Cover the core chemical compound, including its chemical formula, stereochemistry, or derivatives
- Cover methods for synthesizing the compound
- Cover therapeutic applications, including specific indications and doses
Dependent claims
- Specify particular substituents or modifications
- Narrow the scope to specific formulations, such as controlled-release matrices
- Detail specific methods of administration, including dosage schedules or combination therapies
Example claim structure
- Claim 1: A chemical compound with a defined molecular structure, including possible stereoisomers
- Claim 2: A method of administering the compound for treating a disease
- Claim 3: A pharmaceutical formulation comprising the compound and a pharmaceutically acceptable carrier
The claims are constructed to maximize patent coverage while avoiding prior art by adding specific structural or procedural limitations.
What is the patent landscape surrounding US Patent 9,604,018?
Related patents and patent families
- The patent is part of a family filed in multiple jurisdictions, including Europe (EP), China (CN), and Japan (JP), with counterparts potentially filed in Canada, Australia, and other regions.
- Earlier patents in related families protect precursor compounds, methods, or formulations, indicating layered protection and potential for patent thickets.
Key competitors and licensors
- Major pharmaceutical companies with extensive oncology or inflammatory product portfolios control patents in the same class
- The patent owner may have licensing agreements with research institutions or biotech firms specializing in chemical synthesis or drug delivery systems
Patent validity and challenges
- The patent's priority date is likely 2014 or 2015, considering filing timelines
- Prior art searches include filings from 2009 to 2013, covering known chemical classes, synthetic routes, and therapeutic uses
- Potential invalidation risks include existence of prior art that discloses similar compounds or methods, particularly in literature from patent families or scientific journals
Landscape trends
- The patent fits the trend of protecting small molecules targeting specific pathways
- Increasing filings around formulation techniques indicate strategic efforts to extend patent life and defend against generics
- Focus on combination therapies could lead to future patent filings referencing this patent as a foundational element
Patent expiry considerations
- Patent life extends approximately 20 years from filing, meaning expiration could occur around 2034–2035, considering the patent's likely filing year
- Patent term adjustments or pediatric extensions are uncommon but possible

- The patent landscape includes filings in major jurisdictions, with layered protection that complicates patent challenges.
- The patent’s enforceability depends on the novelty and non-obviousness of the claimed structure relative to prior art.
- Expiry around 2034–2035 suggests a medium-term patent life, with ongoing potential for extensions or follow-up patents.
- Commercial value hinges on clinical development success and patent enforcement strategies in jurisdictions with significant markets.
FAQs
1. What are the main risks to patent validity for US Patent 9,604,018?
Risk factors include prior art disclosures that predetermine the chemical structure or therapeutic use, as well as claims that are overly broad or lack inventive step.
2. How does the patent landscape impact generic drug development?
The broad claims can delay generic entry; however, patent challenges can lead to invalidation if prior art demonstrates obviousness or lack of novelty.
3. Can the patent be extended beyond its 20-year life?
Extensions are limited mainly to pediatric or patent term adjustments, which are contingent on regulatory reviews and legal provisions.
4. What role do international filings play in the patent’s protection strategy?
They provide territorial rights, prevent parallel generic markets, and create patent thickets that defend market share globally.
5. How does the scope of claims influence potential licensing opportunities?
Broader claims attract licensing interest from biosimilar manufacturers or combination therapy developers seeking to expand patent coverage.
