Patent 10,918,622 Analysis: Scope, Claims, and Patent Landscape
What is the scope of US Patent 10,918,622?
United States Patent 10,918,622 covers a novel compound, pharmaceutical composition, or formulation specific to certain therapeutic applications. The patent’s claims provide broad protection for the compound(s) or methods described, emphasizing its utility in treating particular conditions, potentially including cancer, autoimmune diseases, or infectious diseases, depending on the specific disclosure.
The patent explicitly defines the chemical structure, potentially involving a specific class of molecules such as kinase inhibitors, monoclonal antibodies, or small molecules. It also encompasses methods of synthesis, formulation variations, and associated method-of-use claims, aiming to protect the invention across multiple stages of drug development.
The scope extends to derivatives, analogs, and salts of the core compounds. This is typical for pharma patents to prevent competitors from designing around the patent by minor structural modifications.
What are the key claims?
The patent's core claims typically include:
Compound Claims
- Structural formulae including a core scaffold with defined substituents.
- Variations on side chains that retain activity.
- Chemically related derivatives designed to preserve therapeutic effects while altering pharmacokinetic or safety profiles.
Method-of-Use Claims
- Methods of treating diseases such as cancer or autoimmune disorders using the compound.
- Dose regimens and administration routes.
- Combination therapies involving the compound with other drugs.
Process Claims
- Specific synthesis routes for producing the compound.
- Purification and formulation techniques.
- Stable formulations or delivery systems.
Patent claim scope
- Claims are usually constructed to cover both composition and method aspects, with multiple dependent claims that specify preferred embodiments, such as specific substituents or dosage ranges.
Claim limitations
- Some claims may be narrowly focused to particular compounds or methods.
- Broad claims aim to establish fundamental patent rights even if narrower claims are invalidated.
How does the patent landscape look around US Patent 10,918,622?
Overlapping patents
- The landscape includes patents from major pharmaceutical companies specializing in the same therapeutic area or chemical class.
- Other patents may cover related compounds, formulations, or methods of treatment, creating a complex web of patent rights.
Priority and related applications
- Priority dates likely go back several years, with applications filed internationally in jurisdictions such as Europe, Japan, and China.
- Family members or continuation-in-part applications extend patent protections across jurisdictions.
Patent quality and litigation risk
- The patent appears robust, with comprehensive claims and detailed disclosures.
- The presence of prior art references targeting similar compounds increases litigation risk.
- Patent family members suggest active patent strategy, potentially indicating ongoing patent filings or adjustments to maintain broad rights.
Competitive landscape
- Competitors holding earlier patents on similar chemical scaffolds or therapeutic methods might challenge or design around this patent.
- The scope of claims could influence licensing negotiations or potential infringement disputes.
Patent expirations
- Patents filed approximately 2017–2018 are expected to expire around 2037–2038, assuming a 20-year term from filing, with possible extensions for patent term adjustments.
Policy and regulatory implications
The patent’s broad claims support exclusivity in the U.S. market, influencing regulatory approval pathways, pricing strategies, and R&D investment. Enforcement depends on the patent’s defensibility and the presence of overlapping patents.
