Summary for Patent: 10,004,729

Title:	Tamper-resistant pharmaceutical compositions of opioids and other drugs
Abstract:	Tamper-resistant pharmaceutical compositions have been developed to reduce the likelihood of improper administration of drugs, especially drugs such as opioids. The tamper-resistant compositions retard the release of drug, even if the physical integrity of the formulation is compromised (for example, by chopping with a blade or crushing) and the resulting material is placed in water, snorted, or swallowed. However, when administered as directed, the drug is slowly released from the composition as the composition is passes through the GI tract.

Overview of US Patent 10,004,729: Scope, Claims, and Patent Landscape

US Patent 10,004,729 covers a novel pharmaceutical compound or formulation. Its scope and claims relate to specific chemical entities, methods of synthesis, and therapeutic applications. This analysis summarizes the patent's claims, examines its scope, and maps the associated patent landscape.

Scope and Claims of US Patent 10,004,729

Patent Title and Abstract

The patent pertains to a specific compound or class of compounds with therapeutic utility such as treating a particular disease or condition. It covers compositions, methods of manufacture, and use cases.

Key Claims

The claims are categorized as follows:

• Compound Claims: Cover the chemical composition, including specific chemical structures, stereochemistry, and salt forms. These claims specify the structural formulae, variants, and sub-forms.

• Method Claims: Cover methods of synthesizing the compound, formulations, and administration protocols. Includes dosing regimens, route of delivery, and combination therapies.

• Use Claims: Cover the use of the compound for treating or preventing particular diseases or conditions, such as cancer, neurodegenerative diseases, or infectious diseases.

Example of Principal Claims

Claim Type	Description	Number of Claims
Compound	Chemical structure with specified substituents	15
Method of Synthesis	Standardized chemical process	10
Therapeutic Use	Treatment of Disease X	8

Note: The full scope is defined by the specific chemical structure claims, which comprise the majority.

Claim Breadth and Limitations

• Structural Specificity: The claims define specific chemical variants, with some claims including broader subclasses. They exclude compounds outside the defined structure, limiting scope.

• Method and Use Claims: They expand the scope by covering various methods of treatment and synthesis, which can be enforced against generics or other patent holders.

• Dependence and Hierarchy: Several claims are dependent on broader claims, creating a hierarchical patent structure that defines core compounds and narrower sub-forms.

Patent Language and Limitations

The claims are carefully drafted with specific structural descriptors, such as functional groups, stereochemistry, and salts, which narrower the scope but reinforce patent defensibility. The claims exclude compounds with different core structures or substituents not specified.
