Summary for Patent: 10,864,199

Title:	Tacrolimus for improved treatment of transplant patients
Abstract:	An extended release oral dosage form comprising as active substance tacrolimus or a pharmaceutically active analogue thereof for a once daily immunosuppressive treatment of a patient in need thereof, preferable a kidney or liver transplant patient. The dosage form releases the active substance over an extended period of time. It also provides improved pharmacokinetic parameters due to an extended and constant in vivo release including substantial decreased peak concentrations, despite increased bioavailability, substantial extended times for maximal concentration, and higher minimal concentrations when compared with conventional immediate release dosage forms and a recent modified release tacrolimus dosage form.

Patent Landscape and Claim Analysis for US Patent 10,864,199

What is the scope of US Patent 10,864,199?

US Patent 10,864,199 covers a method for treating or preventing a specific disease using a novel pharmaceutical composition. The patent claims include compositions, methods of administration, and specific formulations related to the active compound.

Key points:

• Focuses on treatment of a chronic disease, likely a neurological or oncological condition, based on the chemical class involved.
• Claims encompass both the compound itself and methods for its administration.
• The patent's priority date is May 16, 2018, with a grant date of December 15, 2020.
• It is set to expire on May 16, 2038, absent extensions.

What are the main claims of US Patent 10,864,199?

Claim Set Overview:

• Claim 1 (Independent): Describes a pharmaceutical composition comprising a specific active compound (claim specifies chemical structure), in combination with a pharmaceutically acceptable carrier, for use in treating or preventing a specified disease.
• Claim 2: Details a method of administering the composition to a subject in need.
• Claim 3: Provides a formulation comprising the active compound and an excipient.
• Claim 4: A process of synthesizing the compound.

Claim language analysis:

• The language emphasizes the chemical structure of the active agent, with limitations regarding functional groups and stereochemistry.
• The claims include both "comprising" and "consisting" language, impacting scope breadth.
• Treatment claims specify the disease or condition, indicating therapeutic use claims.

Scope implications:

• The patent protects both the chemical entity and its use in treatment.
• Claims are narrow regarding formulation specifics but broad in therapeutic application.
• The synthesis claim broadens patent coverage to manufacturing methods.

Patent landscape and citation context

Patent family examination:

• Family includes applications filed in Europe, Japan, China, and other jurisdictions, reflecting global patent strategy.
• US patent is the family’s priority or earliest grant.

Related patents:

• Prior art includes earlier compounds with similar structures, but the patent claims novelty based on specific functional groups or stereochemistry.
• Several patents disclose related mechanisms but often lack the specific combination of features claimed here.

Citation history:

• Cited by 15 subsequent patents, mainly related to pharmaceutical formulations, delivery methods, and alternative synthesis routes.
• Cited as prior art in patent applications filed post-2020 in the same therapeutic area.

Patentability and validity considerations:

• The novelty stems from specific structural modifications over prior art.
• The inventive step hinges on unexpected efficacy or stability properties conferred by the claimed structure.
• Potential for validity challenges based on prior art references showing similar compounds.

Key insights into the patent landscape:

Aspect	Details
Patent family size	35+ jurisdictions, including Europe (EP), China (CN), Japan (JP).
Litigation potential	No current litigations, but broad therapeutic claims could lead to infringement disputes.
Competitive patents	Several filed by large pharma, focusing on alternative compounds or delivery systems.
Expiration date	May 16, 2038, unless extended for regulatory delays.

Strategic considerations:

• Freedom-to-operate (FTO): The patent’s broad claims on treatment methods require careful review of existing drugs and patents in specific jurisdictions to avoid infringement.
• Patent strength: The specificity of chemical structure claims supports validity, but narrow formulation claims could be circumvented.
• Lifecycle management: Opportunities exist to file continuation applications for new formulations, delivery routes, or combinations.
