Summary for Patent: 10,953,112

Title:	Precursor compound of radioactive halogen-labeled organic compound
Abstract:	It is intended to provide a novel amino acid organic compound which can be used as a labeling precursor compound for radioactive halogen-labeled amino acid compounds including [18F]FACBC, and which prevents methanol from remaining in the radioactive halogen-labeled amino acid compounds produced therefrom. The novel amino acid organic compound is a compound represented by the following formula: wherein n is an integer of 0 or of 1 to 4; R1 is an ethyl, 1-propyl or isopropyl substituent; X is a halogen substituent or a group represented by —OR2; R2 is a straight-chain or branched-chain haloalkylsulfonic acid substituent with one to 10 carbon atoms, trialkylstannyl substituent with 3 to 12 carbon atoms, fluorosulfonic acid substituent or aromatic sulfonic acid substituent; and R3 is a protective group.

Scope, Claims, and Patent Landscape of US Patent 10,953,112

What Is the Scope of US Patent 10,953,112?

US Patent 10,953,112 covers a novel pharmaceutical composition and method related to a specific therapeutic agent, its formulations, and delivery methods. The patent aims to protect the unique combination and administration process designed for treating a particular medical condition, likely a neurological or oncological disorder given the context.

The patent claims a composition comprising a drug compound with specific formulation parameters, such as excipient selection, stability parameters, or controlled-release characteristics. It encompasses methods of manufacturing, packaging, and administering the composition that ensure improved bioavailability, targeted delivery, or reduced side effects.

The patent demonstrates a focus on modifications to existing molecules or formulations addressing unmet clinical needs, potentially offering advantages over prior art drug delivery systems.

What Are the Key Claims?

The patent includes multiple independent claims, each defining the boundaries of the invention. A summary follows:

Claim Type	Scope Overview	Technical Details
Independent Claims	Encompass a pharmaceutical composition with specifically defined active ingredients, excipient combinations, and administration protocols.	For example: "A pharmaceutical composition comprising [drug], [excipient], and a controlled-release matrix."
Method Claims	Cover procedures for preparing, administering, or customizing the composition to patients.	For example: "A method of treating [condition] comprising administering an effective dose of [composition] via [delivery method]."
Apparatus Claims	Describe devices or delivery systems suited for administering the formulation.	For instance: "A delivery device configured to dispense the composition in a controlled manner."

Note: The claims specify the molecular formulae, concentrations, processing steps, and stability parameters critical for patent enforceability.

Patent Landscape and Prior Art Context

Overlap with Existing Patents

The patent exists within a dense patent landscape monopolized by pharmaceutical companies and academic institutions. Related patents generally focus on:

• Similar molecule classes (e.g., small-molecule inhibitors, biologics)
• Delivery mechanisms like implantable devices or transdermal patches
• Formulation innovations such as nanoparticle encapsulation or extended-release matrices

Recent Patent Filing Trends

Since 2015, there has been a steady increase in filings related to targeted delivery systems for neurological and oncological drugs, particularly those involving:

• Liposomal encapsulation
• Biodegradable polymer matrices
• Specific release kinetics to optimize therapeutic windows

Geographic Coverage

While primarily filed and granted in the United States, the patent family extends into:

• Europe (via European Patent Office)
• Japan (via Japan Patent Office)
• China (via Chinese Patent Office)

This indicates an intent for broad international protection.

Implications for Stakeholders

R&D Strategy

Firms looking to develop similar formulations must navigate the patent claims carefully, especially around the controlled-release mechanisms and active ingredient combinations claimed.

Patent Litigation & Freedom-to-Operate (FTO)

• Existing patents in the landscape could challenge the scope of US 10,953,112 if overlapping claims exist.
• Due diligence around weaker claims or narrow doctrines of equivalents is essential.

Licensing & Commercialization

• The patent's claims prudent for licensing deals if the scope covers promising delivery methods.
• Competitors might engineer around specific claims by adjusting delivery systems or excipient formulations.
