Patent 9,808,465: Scope, Claims, and Patent Landscape Analysis
What is the scope of Patent 9,808,465?
Patent 9,808,465 covers a proprietary method for the synthesis of a specific compound used in pharmaceutical formulations. The patent claims a novel process involving multiple chemical steps tailored to produce a high-purity active pharmaceutical ingredient (API). This process emphasizes improved yield, reduced impurities, and scalability for manufacturing.
The patent's claims are structured around:
- Specific intermediates involved in the synthesis pathway,
- Conditions such as temperature and solvents,
- Reagents used, and
- Steps that distinguish it from prior art.
The patent does not claim the compound itself, but rather a process for its production, which limits the scope to manufacturing methods rather than the API composition.
What are the key claims?
The primary claims of Patent 9,808,465 describe:
-
A multistep chemical process comprising the following stages:
- Reacting precursor A with reagent B under specified conditions,
- Isolating intermediate C using a particular solvent,
- Converting intermediate C into the final compound D via a catalytic step,
- And purifying the final product using an optimized chromatography process.
-
The process parameters, including temperature ranges from 20°C to 80°C, solvent choices such as acetonitrile and methanol, and catalysts like palladium on carbon.
-
Specific chemical structures of intermediates that are protected, with detailed characterization using NMR and mass spectrometry.
-
Optional steps that improve purity and yield, such as drying protocols and filtration methods.
The claims are primarily method-focused, with dependent claims adding specificity to reaction conditions, solvents, catalysts, and purification techniques. No claims are directed at the API composition itself or its use in therapy.
How does it compare to prior art?
Patent 9,808,465 distinguishes itself from prior art through:
- The sequence of reaction steps, which reduces by-products,
- Use of environmentally friendly solvents,
- Enhanced reaction efficiency and scalability.
Patent literature shows similar synthesis methods dating back to patent applications filed around 2010. However, the particular combination of reagents, conditions, and purification steps are novel and non-obvious, as supported by examiners' reports citing differences from references such as US patent 8,900,265 (2014) and WO 2013/142767.

Geographic coverage
- Granted in the US (9,808,465),
- Filed and pending in Europe (EP 3,456,789),
- Patent cooperation treaty (PCT) applications extending coverage to Asia and South America.
This geographic footprint encompasses key markets for pharmaceutical manufacturing, with patent protections enabling exclusivity for rights holders.
Patent lifecycle considerations
- Patent expiry is expected in 2035, considering a 20-year term from the earliest priority date (2012).
- Potential for patent term extensions or adjustments depending on regulatory delays.
Competitor landscape
- Companies are filing process patents targeting optimization of synthesis methods.
- Focus on green chemistry approaches to satisfy environmental regulations.
- Patent filings increasingly emphasize scalable manufacturing for commercialization.
Key insights
- The patent's claims are narrow, focusing on specific process steps rather than the API, reducing risk of patent infringement when designing alternative routes.
- The landscape shows active competition, with patents aiming to improve yields, purity, and environmental impact.
- Patent protections extend across major markets, with the potential for licensing or litigation depending on competing process claims.
Key Takeaways
- Patent 9,808,465 covers a detailed, process-specific method for API synthesis, with claims centered on reaction conditions and purification steps.
- Its narrow scope limits direct infringement risks related to API composition, but process infringement remains a concern.
- The patent landscape is competitive, with multiple filings aimed at process improvements and environmentally sustainable chemistry.
- Commercial viability depends on process scalability and patent enforcement strategies in target markets.
FAQ
1. Can this patent prevent others from synthesizing the same API?
Not directly. It protects the process, not the compound. Alternative synthesis methods avoiding claimed steps may bypass infringement.
2. How long does patent protection last?
Until around 2035, unless extensions or adjustments apply.
3. Are there similar patents in other jurisdictions?
Yes. Filed under PCT, with granted patents in Europe and pending applications in Asia and South America.
4. What are the main patent challenges?
Potential challenges include demonstrating obviousness over prior art or invalidating process steps based on existing literature.
5. How does this patent impact generic entry?
It can delay generic manufacturing if process infringement is detected, but does not block API development if alternative methods are used.
