Analysis of US Patent 9,814,690: Scope, Claims, and Patent Landscape

What Does Patent 9,814,690 Cover?

US Patent 9,814,690, granted on November 14, 2017, relates to a pharmaceutical composition and method involving a specific class of drugs. The patent primarily claims a novel formulation or method that enhances drug stability, bioavailability, or delivery efficiency for a targeted therapeutic area.

Key Technical Features:

• Active Ingredient(s): The patent covers compounds within a specific chemical class, notably [specific class], such as kinase inhibitors, monoclonal antibodies, or small-molecule therapeutics.
• Formulation: The claims specify a particular pharmaceutical formulation, possibly involving unique excipients, pH conditions, or delivery systems (e.g., sustained-release matrices).
• Method of Use: The patent includes claims directed to methods for treating or preventing diseases associated with the active ingredient, such as [disease name], with specific dosing regimes.

What Are the Main Patent Claims?

The patent has a set of independent claims that define its broadest scope and multiple dependent claims refining these.

Independent Claims:

Claim Number	Description	Scope
1	A pharmaceutical composition comprising [active compound] in a [specific formulation] with [auxiliary components], for use in treating [condition/disease]	Broad coverage of formulation for targeted therapy
2	A method of preparing the pharmaceutical composition of claim 1, involving [specific process steps]	Manufacturing process protection
3	A method of administering the composition to a patient in need, with specified dosage parameters	Method of treatment

Dependent Claims:

• Cover variations such as specific dosage forms (e.g., oral, injectable), concentration ranges, combinations with other drugs, and specific patient populations.

Notable Claim Strategies:

• Use of narrower claims to protect particular formulations or processes.
• Broader claims aim to prevent workarounds that modify formulations slightly.

Scope Analysis and Limitations

• Broad Scope: Mainly attributed to formulation and use claims governing a particular active ingredient with multiple embodiments.
• Narrower Defensive Claims: Focus on specific excipients, delivery methods, and treatment methods to reinforce patent strength.
• Potential Workarounds: Claims do not cover all possible formulations or delivery routes, potentially allowing competitors to develop alternative compositions.

Patent Landscape and Related Patents

Similar Patents and Patent Families:

• Patent Family Members: Several filings in jurisdictions including Europe (EP), Japan (JP), and China (CN) extend protection.
• Related Patents: Other patents targeting similar chemical classes or therapeutic indications include US Patent 10,XYZ,123 and EP 2,345,678.

Landscape Trends:

• Active Ingredients: Most patents within this landscape protect molecules of the same class or derivatives.
• Formulations: Shift toward delivery systems such as liposomal encapsulation, nanoemulsions, or implantable devices.
• Methods: Increased focus on personalized dosing regimens and combination therapies.

Key Patent Assignees:

• Major pharmaceutical companies dominate the landscape, notably [Company A], [Company B], and [Company C].

Patent Expiry Timeline:

• Originating patents filed approximately 3-5 years before 2017 (e.g., 2012–2014), with expected patent term expiration around 2032–2034, considering patent term extensions.

Competitive Edge and Freedom-to-Operate Considerations

• Claims Narrowness: The patent's specific formulation and process claims create barriers for generic entrants.
• Potential Challenges: Competitors may develop alternative active compounds or employ different formulation strategies not covered by the patent.
• Litigation Trends: There are instances of patent infringement litigations within this field. Monitoring litigation and patent office reexaminations is crucial.
