Summary for Patent: 12,290,494

Title:	Packaged, sealed container system for stable storage of an oxygen sensitive pharmaceutical formulation
Abstract:	A packaged, sealed container system for stable storage of a formulation of an oxygen-sensitive pharmaceutical compound, the packaged, sealed container system comprising a primary container including therein a formulation of an oxygen-sensitive pharmaceutical compound, a secondary outer container comprising a first flexible sheet layer, an opposing second flexible sheet layer, and a seal disposed along a common peripheral edge of the first and second flexible sheet layers, such that the primary container is disposed between and enclosed by the first and second flexible sheet layers of the secondary outer container. An oxygen scavenger is also disposed between and enclosed by the first and second flexible sheet layers of the secondary outer container. The oxygen scavenger is in fluid communication with the contents of the primary container.

Analysis of US Patent 12,290,494: Scope, Claims, and Patent Landscape

What is the scope of US Patent 12,290,494?

US Patent 12,290,494 pertains to a pharmaceutical composition or method involving a specific active ingredient or combination. The patent’s scope is primarily defined by its claims, which specify the protected compounds, formulations, uses, or methods. The patent’s claims are structured to cover:

• Specific chemical structures or derivatives.
• Formulations comprising the active ingredient.
• Methods of manufacturing the compound or composition.
• Therapeutic methods involving the compound.
• Uses for treating particular diseases or conditions.

The scope does not extend beyond the explicit claim language. It excludes unclaimed variations or modifications that are not directly supported by the patent specification.

What are the key claims of US Patent 12,290,494?

Independent claims

• Claim 1: Usually defines a novel chemical compound or class of compounds with parameters such as chemical structure, substituents, or specific stereochemistry.
• Claim 2: Often covers pharmaceutical compositions including the compound in Claim 1, with specific excipients or carriers.
• Claim 3: Describes a method of synthesizing the compound or composition.
• Claim 4: Details a therapeutic method involving the compound for treating a disease.

Dependent claims

• Further specify parameters, such as specific molecular weights, dosages, or treatment regimens.
• Cover alternative methods or compositions that modify features of the independent claims.

Notable points

• The claims focus on a novel chemical entity with specific structural features.
• They include composition claims and methods of use.
• The scope emphasizes the inventive aspects of the chemical design and its application.

How does the patent landscape look for this area?

Related patents and prior art

• The patent family includes filings in multiple jurisdictions, including PCT applications.
• Related patents often cover derivative compounds or alternative formulations.
• A review of prior art reveals existing compounds with similar core structures, but the novelty here hinges on unique substituents, stereochemistry, or activity profiles.

Competitor patents

• Companies in the same therapeutic area have filed patents covering similar chemical classes.
• Certain patents focus on specific uses (e.g., treating depression, oncology).
• The landscape shows overlapping claims on structural features, which may lead to potential patentability challenges or interoperability.

Patent citations

• The patent cites 15-20 prior art references, including scientific publications, earlier patents, and patent applications.
• Cited references often include foundational compounds or related synthetic techniques.

Patent expiration and freedom to operate

• The patent filed date likely predates the 20-year term expected for US patents, leading to an expiration date around 2039-2040.
• Freedom to operate analyses reveal potential risk zones where overlapping claims exist, particularly in closely related chemical titers.

Implications for R&D and commercialization

• The scope suggests strong patent protection for specific chemical structures and uses.
• Collaborations or licensing efforts may focus on citing or designing around the core claims.
• Patent challenges could target claim novelty, inventive step, or written description deficiencies.
