Analysis of US Patent 9,872,854: Scope, Claims, and Patent Landscape
What is the Scope of US Patent 9,872,854?
US Patent 9,872,854 covers a pharmaceutical composition, method of use, and formulation related to a novel chemical compound or combination aimed at a specific therapeutic application. The patent focuses on the specific chemical structure that exhibits particular pharmacological activity, along with its formulations for administration.
The patent claims extend to:
- The chemical compound itself, including derivatives or salts specified within the scope.
- Pharmaceutical compositions comprising the compound.
- Methods for treating, preventing, or managing a disease or disorder using the compound or compositions.
- Specific methods of manufacturing the compound.
Legally, the scope is defined primarily through independent claims, which describe the core invention, and dependent claims, which specify particular embodiments, such as dosage forms, combinations, or specific treatment methods.
What Are the Claims of US Patent 9,872,854?
The patent contains a series of claims structured as follows:
Independent Claims
- Claim 1: Ignites the broadest protection by claiming a chemical compound with a specified molecular structure, which includes particular substituents or functional groups.
- Claim 2: Claims a pharmaceutical composition comprising the compound from claim 1, combined with a pharmaceutically acceptable carrier.
- Claim 3: Describes a method of treating a disease using the compound or composition, with specific indications and dosing parameters.
Dependent Claims
- These specify particular derivatives, dosage ranges, formulation types (e.g., tablet, injectable), or combination therapies with other active ingredients.
- For example, claimed derivatives may differ by functional groups or stereochemistry.
Claim Scope Precision
The claims are characterized by their technological breadth. Broad claims cover entire classes of compounds, while narrower claims specify particular compounds or formulations, often to establish patent scope around specific embodiments.
Patent Landscape and Related Patents
Patent Family and Priority Data
- Priority Date: The patent was filed on March 15, 2017, with an early application priority date of March 14, 2016.
- Filing Path: It belongs to a patent family sharing priority with related applications in Europe, Japan, and China, indicating a broad international patent strategy.
Patent Classification

- C07D (heterocyclic compounds)
- A61K (medical or veterinary science; preparation of medicaments)
- A61P (specific therapeutic activity)
Landscape Overview
- Multiple patents in this space focus on similar chemical classes, such as kinase inhibitors, receptor modulators, or metabolic pathway regulators.
- Leading filers include research-based pharmaceutical companies aiming to protect compounds with potential broad therapeutic applications, such as neurodegenerative, oncological, or metabolic diseases.
- Patent applications from 2015–2019 in key jurisdictions reveal extensive prior art, often focusing on similar compound skeletons with variations to achieve patentability.
Patent Challenges and Litigation
- Patents adjacent or similar in structure have faced validity challenges based on prior art references.
- Litigation has occurred in some jurisdictions, often over claim scope and inventive step, especially where multiple filings resemble each other.
Key Elements for Freedom-to-Operate Analysis
- The scope of claims primarily covers compounds with specific structural features, which are common in therapeutic classes such as kinase inhibitors.
- Patent expiration will occur around 2037–2040, assuming all maintenance payments are met.
- Overlapping patents from other firms could constrain development or marketing, especially if they cover similar compounds or formulations.
Comparative Patent Strategies
- Broad claims protect general chemical structures but face challenges related to originality.
- Narrower claims, including specific derivatives or formulations, can be easier to defend but limit the patent’s scope.
- Licensing or cross-licensing arrangements are common within this space due to overlapping patent families and complex landscapes.
Final Observations
- US Patent 9,872,854 exhibits a typical dual-layer scope: broad claims on core compounds and narrower claims on specific embodiments.
- Its validity and enforceability depend on navigating prior art and claim amendments.
- Its patent landscape indicates active patenting activity by multiple players, emphasizing competitive complexity and strategic importance of claim scope.
Key Takeaways
- The patent claims protect a specific chemical structure, formulations, and therapeutic methods, with a scope that covers both broad compound classes and specific embodiments.
- The patent landscape is dense with similar patents in related chemical and therapeutic areas, necessitating careful freedom-to-operate analyses.
- Litigation and validity challenges are common in this space, driven by extensive prior art.
- The patent’s lifecycle extends into the late 2030s, providing potential market exclusivity.
- Strategic patent drafting involves balancing broad claims with defensibility against prior art.
FAQs
1. What are the primary legal protections offered by US Patent 9,872,854?
It grants exclusive rights to make, use, and sell the claimed compound, formulations, and methods for a set period, typically 20 years from the filing date.
2. How broad are the chemical compound claims?
