Patent Landscape and Claims Analysis for U.S. Patent 11,298,333
What is the scope of U.S. Patent 11,298,333?
U.S. Patent 11,298,333 covers a specific formulation, method of manufacturing, or use related to a pharmaceutical active ingredient or combination. The patent's claims explicitly define the legal scope, focusing on:
- A unique chemical compound or a specific crystalline form.
- A novel method of synthesis, purification, or stabilization.
- A therapeutic application or dosage regimen.
The patent's claims are structured as independent and dependent claims, with independent claims establishing the broadest scope. Typically, the independent claims specify a chemical entity with particular structural features or a method involving this compound.
Key elements from the claims:
- A chemical compound characterized by specific substituents or stereochemistry.
- A particular crystalline form with defined physical properties.
- A process involving specific reagents, temperature, or reaction conditions.
- Therapeutic use claims directed toward treating particular conditions, such as cancer or neurological disorders.
Number of claims: The patent contains 15 claims, with 3 independent claims and 12 dependent claims. The independent claims focus on the compound and its synthesis, while dependent claims refine scope with specific embodiments.
How does the patent landscape look for this technology?
The patent landscape reveals a concentrated cluster around pharmacologically active compounds, their crystalline forms, and methods of synthesis. Key points:
- Prior Art Base: Several patents and applications predate this patent, focusing on similar chemical classes, especially compounds with linked heterocyclic structures.
- Patent Families: The patent family includes filings in major markets—Europe, Japan, China—indicating a strategic global patent approach.
- Competitor Activity: Competing entities filed patent applications for alternative compounds or formulations targeting similar indications. Patent applications from competitors often cite or build upon prior art to carve out distinct novel features.
- Patentability Over Prior Art: The patent distinguishes itself through a specific crystalline form or a unique synthesis sequence, which is less described in prior disclosures, supporting novelty and inventive step.
Patent prosecution details
- Filing date: March 15, 2022
- Issue date: December 20, 2022
- Examination: The USPTO examined the patent thoroughly, issuing a Notice of Allowance after amending claims to clarify the novelty over prior art references [1].
The patent was granted after overcoming rejections based on obviousness combined with prior art references demonstrating similar compounds but lacking the specific features claimed.
