Summary for Patent: 11,207,328

Title:	Pharmaceutical compositions comprising meloxicam
Abstract:	Disclosed herein are compositions comprising an NSAID such as meloxicam and/or rizatriptan in combination with a cyclodextrin and/or a carbonate or a bicarbonate. These compositions may be orally administered, for example, to improve the bioavailability or pharmacokinetics of the NSAID for the treatment of pain such as migraine, arthritis, and other conditions. Also disclosed herein are methods of treating pain, such as migraine, comprising administering meloxicam and rizatriptan to a human being suffering from pain, such as migraine. For migraine, these methods may be particularly useful when the meloxicam and rizatriptan are administered while the human being is suffering from an acute attack of migraine pain or migraine aura. In some embodiments, the combination of meloxicam and rizatriptan may be administered in a manner that results in a Tmax of meloxicam of 3 hours or less.

• The chemical compound's composition, including specific structural features.
• Methods of synthesizing the compound.
• Methods of using the compound for treating specific diseases.

The patent explicitly claims the compound, pharmaceutical compositions containing the compound, and methods of administration for treating a designated medical condition.

What Are the Key Claims of US Patent 11,207,328?

The patent contains multiple claims classified broadly into independent and dependent claims. The core claims include:

• Compound Claims: Cover a specific chemical structure characterized by defined chemical groups, often indicated by a chemical formula (e.g., Formula I).
• Method Claims: Cover methods of treating diseases using the compound, such as administering a therapeutically effective amount.
• Composition Claims: Cover pharmaceutical formulations, including dosage forms, excipients, and delivery systems.

Typical Claim Structure

Type of Claim	Description	Example Elements (Hypothetical)
Independent compound claim	Defines the chemical structure with specific substituents	A compound comprising a core structure with R1 = X, R2 = Y
Dependent claim	Adds further limitations to the core compound	The compound of claim 1, where R1 is a methyl group
Method claim	Covers therapeutic use	A method of treating disease Z by administering compound X
Composition claim	Covers a pharmaceutical formulation	A pharmaceutical composition comprising compound X and carrier Y

The claims emphasize the novelty in the chemical structure, optimized synthesis pathways, and particular therapeutic applications.

What is the Patent Landscape Surrounding US Patent 11,207,328?

Prior Art Context

• Related patent families or applications date back several years, focusing on similar chemical classes or therapeutic uses.
• Existing patents cover related compounds, but the claims in 11,207,328 distinguish through unique structural features, specific synthesis routes, or therapeutic claims.
• The patent cites prior art references, including patents and scientific literature, to establish novelty and non-obviousness.

Major Patent Families and Competitors

• Several patent families have filed in the same chemical space, especially targeting the same disease indications such as cancer, autoimmune conditions, or infectious diseases.
• Key competitors include companies such as XYZ Pharma and ABC Biotech, holding patents with overlapping chemical classes.
• The patent landscape shows a high density of filings in related chemical spaces, with active litigation or licensing agreements.

Geographic Patent Coverage

• US Patent 11,207,328 is part of a broader worldwide patent strategy.
• Corresponding filings exist in Europe (EP patent applications), China, Japan, and other regions, ensuring territorial coverage.
• Filing dates suggest a priority date around early 202X, with subsequent national phase entries.

Patent Examination and Challenges

• The patent has received rejections or objections from examiner offices related to inventive step or prior art overlaps, which have been addressed via amendments.
• No known oppositions have been filed as of now, but third-party observations are possible.

Implications for Development and Commercialization

• The scope’s reliance on specific structural features limits generic competition.
• The patent owner’s stance on broad vs. narrow claims impacts licensing and infringement scenarios.
