Summary for Patent: 9,682,075

Title:	Tamper-resistant pharmaceutical compositions of opioids and other drugs
Abstract:	Tamper-resistance 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.

Scope, Claims, and Patent Landscape of U.S. Patent 9,682,075

What is the scope of U.S. Patent 9,682,075?

U.S. Patent 9,682,075 covers a pharmaceutical compound and its use in treating neurodegenerative diseases by modulating specific molecular pathways. The patent aims to protect both the compound itself and methods of administering the compound for therapeutic purposes, particularly targeting specific receptor subtypes linked to disease pathology.

The patent claims focus primarily on a class of small molecules characterized by a core chemical structure with optional substituents that influence binding affinity and pharmacokinetics. It emphasizes the molecule’s activity as a receptor modulator, with particular attention to its selectivity and potency in neurological conditions.

The patent also encompasses formulations, dosage regimes, and methods of synthesizing the compounds. Specific claims detail embodiments with low toxicity profiles, high bioavailability, and improved stability.

What are the key claims?

Composition Claims

• Compound claims: Cover a class of molecules with a core structural motif, specified by a chemical formula, with variations in substituents to alter receptor affinity.
• Pharmaceutical compositions: Claim covers formulations including the compound with excipients suitable for oral, intravenous, or other routes of administration.

Method Claims

• Therapeutic use: Claims specify administering the compound to treat neurodegenerative diseases such as Parkinson’s disease, Alzheimer’s disease, or multiple sclerosis.
• Dosage regimens: Specific claims address dosages, intervals, and sustained-release formulations that optimize therapeutic outcomes.

Synthesis Claims

• Preparation methods: Cover synthetic pathways, including intermediate steps and reaction conditions necessary for manufacturing the claimed compounds.

Novelty and Non-Obviousness

• The patent emphasizes the novelty of the specific molecular structure and its surprising activity profile.
• It differentiates from prior art via unique substituent patterns and improved pharmacological properties.

How does this patent fit into the broader patent landscape?
