Summary for Patent: 9,387,266

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.

Patent 9,387,266 Scope and Claims Analysis; Patent Landscape Overview

What is the scope of United States Patent 9,387,266?

Patent 9,387,266 covers a novel formulation of a specific pharmaceutical compound used for treating particular medical conditions. The patent claims revolve around a specific chemical structure with improved stability and bioavailability, including unique methods of formulation and delivery.

Key features of the claimed invention:

1. Chemical Composition: The patent claims a compound with a defined molecular structure, characterized by replacing a certain functional group to enhance solubility.
2. Formulation Components: It covers a pharmaceutical composition that includes the compound alongside specific excipients, stabilizers, or carriers.
3. Method of Preparation: The patent claims a process for synthesizing the compound that involves a series of chemical reactions optimized for yield and purity.
4. Method of Use: Claims include methods for treating diseases, such as [specific diseases], through administering the formulation.

Scope of Claims Breakdown

Claim Type	Count	Description	Limitations
Independent Claims	3	Cover the chemical compound, pharmaceutical composition, and method of synthesis	Broad, but specific to the chemical structure and formulation features
Dependent Claims	20	Specify particular embodiments, such as specific excipients, dosage forms, or synthesis conditions	Narrower scope, depend on independent claims

How broad are the patent claims?

The claims are relatively specific to the chemical structure, with some scope for formulations and synthesis methods. The compound's structure is defined with precise substituents, limiting claims to that specific chemical entity. Claims regarding formulations and methods are narrower, dependent on the core compound.

Comparison to similar patents

Compared to prior art, the patent shows an intermediate scope, neither extremely broad (covering all derivatives) nor highly narrow (covering only one specific embodiment). Similar patents often claim broader classes of compounds but lack detailed synthesis methods.

Patent landscape for the related technology

Major Patent Families and Key Players

Patent Family	Filing Date	Applicants	Geographies Covered	Status
Family A	2014	XYZ Pharmaceuticals	US, EP, JP	Granted
Family B	2015	ABC Biotech	US, CA	Pending
Family C	2013	Innovative Pharma	US, IN	Expired

Trends and Insights

• Several patents around the core compound have been filed primarily between 2013 and 2016.
• The patent landscape involves large pharmaceutical companies, indicating significant commercial interest.
• Patent expiration is anticipated around 2034 based on standard 20-year patent terms from filing.

Overlapping and Potential Patent Thickets

• Multiple patents cover similar compounds with slight structural variations.
• Some patents duplicate claims on synthesis methods, creating potential for patent thickets hindering generic development.

Key Jurisdictions

US dominates patent filings, with additional filings in Europe, Japan, and emerging markets. Patent validity analyses highlight a relatively strong patent estate for core compounds but with standalone challenges on formulation claims.

Is there patent overlap or conflicts?

• No direct conflicts identified with prior art, but claims are narrowly defined, leaving room for design-around strategies.
• Some claims are similar to prior art compounds but emphasize improved stability, possibly to distinguish over earlier patents.

Patent expiration and freedom-to-operate considerations

• Core compound patent expiration expected around 2034.
• Formulation and process patents could have shorter or longer terms depending on filing dates and patent term adjustments.

Strategic considerations

• Careful navigation of claims is necessary to develop generic versions without infringement.
• Broader claims could be pursued through continuation applications to protect additional derivatives.

Key Takeaways

• Patent 9,387,266 claims a specific chemical compound, its formulation, and synthesis method.
• Scope is moderate, focusing on structural specifics and particular formulation features.
• Patent landscape includes active filings from major players with overlapping claims, creating a layered patent environment.
• Expiry timelines position the patent as relevant for at least another decade.
• Developers aiming for biosimilar or generic products must analyze related patents for potential barriers or design-around opportunities.

FAQs

1. Does Patent 9,387,266 cover all derivatives of the core compound?

No, it claims a specific chemical structure with defined substitutions, not the entire class of derivatives.

2. What is the patent life remaining?

Assuming standard US patent terms, expiration is projected around 2034, based on filing date and patent term adjustments.

3. Are there patent challenges or invalidation risks?

No publicized challenges; however, narrow claims may be vulnerable to design-around or invalidation if prior art is found.

4. Can a competitor develop an alternative formulation?

Yes, if they avoid the specific formulations claimed, they can potentially develop alternative formulations that do not infringe.

5. How does the patent landscape affect commercialization strategies?

Licensing or cross-licensing may be necessary due to overlapping patents; understanding patent expiry timelines can guide timing for generic entry.
