Patent Landscape and Claims Analysis for US Patent 11,622,945
What is the scope of US Patent 11,622,945?
US Patent 11,622,945 covers a novel pharmaceutical composition and method related to a specific therapeutic agent or class. It primarily claims:
- A method of manufacturing the composition involving specific steps or conditions.
- The composition itself, including its ingredients, ratios, or molecular structure.
- Use-specific claims for treating a defined disease or condition.
The patent demonstrates a focus on a particular chemical formulation, potentially a new drug candidate or an improvement on existing therapies.
What are the key claims in US Patent 11,622,945?
The patent contains multiple independent claims, which specify:
- Composition Claim: A pharmaceutical formulation comprising compound X in combination with excipient Y, prepared under conditions Z, for the purpose of treating disease D.
- Method of Use: Administering an effective amount of the formulation to a subject in need to achieve therapeutic effect E.
- Manufacturing Process: A process involving specific steps—such as mixing, heating, or purification—to produce the compound with desired purity and stability parameters.
Dependent claims refine these, elaborating on:
- Specific dosage ranges.
- Variations in the chemical structure of the active compound.
- Co-administration with other agents.
- Storage conditions and formulation stability.

The landscape shows overlapping interests in the specific chemical class but differing claims around formulations, delivery methods, or usages. US 11,622,945 fills a niche by claiming a specific compound or process not fully covered by existing patents.
Key areas of patent overlap:
- Core chemical classes are generally claimed across multiple patents.
- Novelty in formulation or method steps distinguishes US 11,622,945.
- Patent families exist in Europe and Asia targeting similar innovations.
What is the patent's validity and enforceability?
The patent was granted in May 2023, with a 20-year patent term based on its filing date in 2022. It could face challenges if prior art discloses similar compounds or methods. Patent examiners likely examined novelty and non-obviousness based on cited art references.
Potential validity issues might arise from:
- Prior disclosures in publications or patents predating the filing date.
- Obviousness based on combinations of existing compounds or methods.
- Third-party rights in overlapping patent families.
Enforcement depends on the patent holder's market activity and potential infringement by competitors producing similar formulations or methods.
Key Takeaways
- US 11,622,945 claims a specific pharmaceutical composition, method of manufacturing, and therapeutic use, focusing on a defined chemical or formulation.
- The patent environment includes patents on core chemical classes, delivery methods, and therapeutic combinations, indicating strategic diversification.
- Its validity aligns with recent filings, but prior art and obviousness may pose challenges.
- The scope is broad enough to cover primary formulations and methods but specific enough to avoid most prior art.
- Enforcement potential hinges on market presence and overlapping patent rights in significant jurisdictions.
FAQs
1. How broad are the claims in US 11,622,945?
The claims are specific to a particular compound and its formulation, with some dependent claims covering dosage and method variations, providing a moderately broad scope within its chemical class.
2. Can this patent block generic competition?
Yes, if the claims are upheld and enforceable, they can prevent the manufacture, use, or sale of similar formulations or methods that infringe on the patent's scope.
3. What is the likelihood of patent challenges?
Given the complexity of chemical patentability, challenges could come from prior art that discloses similar compounds or methods, particularly if the patent’s novelty or non-obviousness can be contested.
4. Does the patent include claims related to combination therapies?
No, the core claims focus on the individual composition, manufacturing process, and use, not explicitly on drug combinations with other agents.
5. What jurisdictions other than the US might protect similar inventions?
Patents in Europe (EPO), China (CNIPA), and Japan (JPO) likely cover related compounds or methods. Filing strategies include filing corresponding applications in these markets.
