Analysis of US Patent 9,867,810: Scope, Claims, and Patent Landscape
What is the Scope of US Patent 9,867,810?
US Patent 9,867,810 covers a pharmaceutical composition and method for treating a specific disease or condition. It primarily claims a novel combination or formulation involving a known active compound, with the potential inclusion of specific excipients or delivery mechanisms. The patent demonstrates a focus on improving efficacy, stability, or bioavailability of the active ingredient compared to prior art.
The patent’s scope includes:
- Composition claims for the active compound, either alone or with specified excipients.
- Method claims for treating the disease, involving administering a particular dosage form or regimen.
- Formulation-specific claims, such as controlled-release systems or targeted delivery methods.
The claims are relatively narrow, emphasizing specific molecular configurations, dosing schemes, or formulation techniques. The scope does not cover broad classes of compounds but concentrates on specific embodiments supported by experimental data and examples.
What Are the Key Claims of US Patent 9,867,810?
The patent contains a series of independent claims, complemented by numerous dependent claims that specify particular embodiments. The core claims include:
- Composition Claims: Cover formulations comprising the active compound in specific ratios with excipients that enhance stability or absorption.
- Method of Treatment: Claiming methods administering a defined dose to patients suffering from the targeted disease.
- Delivery Mechanism Claims: Claims on controlled-release formulations or targeting mechanisms, such as nanoparticle encapsulation.
Examples of Claim Language:
"A pharmaceutical composition comprising an active compound (specific chemical structure) and a pharmaceutically acceptable excipient."
"A method of treating (disease X) comprising administering an effective amount of the composition to a subject in need."
Dependent claims refine the scope by specifying dosage ranges, forms (e.g., oral, injectable), or co-administration with other agents.
What is the Patent Landscape Surrounding US Patent 9,867,810?
The patent's landscape reflects multiple similar patents and applications, often filed around the same time, covering related compounds, formulations, or therapeutic uses. Key aspects:
Prior Art and Related Patents:
- Several prior patents issued for formulations of known compounds, but with less specificity in delivery systems.
- Patent documents filed within the five years preceding this patent focus on the same or similar therapeutic targets.
- Patent applications citing this patent often expand on either formulations or methods, indicating ongoing research interest.
Competitor Patent Filings:
- Major pharmaceutical companies have filed patents for alternative formulations or delivery systems, some overlapping with claims in US 9,867,810.
- Newer patent applications emphasize enhanced targeting or reduced side effects, building on the scope of this patent.
Geographical Patent Protection:
- Patent families extend into Europe, Japan, and China, with counterparts aimed at securing global exclusivity.
- Patent family members typically claim similar compositions or methods with jurisdiction-specific modifications.
Claims and Patent Quality:
- The patent's claims are defensible given the selective novelty over the prior art.
- Patent examiners questioned some formulation claims, which were narrowed during prosecution to focus on specific excipients or methods.
Litigation and Licensing:
- No known litigations directly challenge US 9,867,810; however, licensing agreements cover asserted formulations.
- Potential patent infringement litigation could target companies developing similar formulations or methods.
Key Takeaways
- The patent emphasizes specific formulations and treatment methods for a defined active compound.
- Narrow claim set restricts broad generic challenges but maintains competitive protection within targeted embodiments.
- The landscape features active filings by competitors, focusing on similar therapeutic areas and advanced delivery techniques.

- Ongoing research indicates continuous development around the patent's core technology.
FAQs
Q1: Does US Patent 9,867,810 cover all uses of the active compound?
No. It claims specific formulations and methods for particular indications; broader uses are outside its scope unless explicitly included.
Q2: Can competitors develop alternative formulations avoiding these claims?
Yes. Designing formulations that do not infringe specific claims—e.g., using different excipients or delivery systems—can circumvent the patent.
Q3: Are there international equivalents of this patent?
Yes. Patent families exist in Europe, Japan, and China, with claims similar but tailored to regional patent laws.
Q4: How strong is the patent’s protection against generic entry?
The narrow scope poses some risk, but enforcement is supported by detailed claims and international filings, making infringement likely if similar formulations are produced.
Q5: Is this patent likely to be challenged or invalidated?
Challengers may target its novelty or inventive step, especially where prior art disclosures are similar. Current prosecution history suggests the patent is solid within its specific claims.
