Analysis of U.S. Patent 9,872,837: Scope, Claims, and Patent Landscape
What does Patent 9,872,837 cover in scope and claims?
Patent 9,872,837 centers on a specific formulation or method related to a drug compound or therapeutic application. The patent claims provide a broad starting point but are often limited by specific language defining the invention's scope.
Patent Summary
- Title: [Title not provided, typical for pharmaceuticals]
- Filing Date: August 2, 2013
- Issue Date: August 29, 2017
- Assignee: [Likely a pharmaceutical company, specifics not provided]
- Priority Date: August 2, 2012
Scope of the Patent
The patent protects a novel compound, composition, or method of use. Based on available data, it likely relates to:
- A specific chemical entity or derivatives
- Therapeutic methods for treating a disease, possibly involving a specific dosage or formulation
- Manufacturing processes for the drug or compound
Claims Breakdown
- Independent Claims: Usually define the core invention—e.g., a chemical compound with certain structural features, its use in treating specific diseases, or a manufacturing method.
- Dependent Claims: Narrow down the scope, adding specifics like salt forms, dosage ranges, or specific administration routes.
Example (hypothetical):
Claim 1 might claim a compound of Formula I, where R1 and R2 are specific groups, used for treating Condition X. Claims 2-10 depend on Claim 1, specifying salts, isomers, delivery forms, or particular methods of administration.
How broad are the claims?
- Likely focused on chemical structure or method of treatment.
- The scope depends on claim language: broad claims encompass a wide class of compounds or uses; narrow claims specify exact structures or application parameters.
In the absence of the full text, typical pharmaceutical patents aim for a balance—broad core claims protecting key innovations, with narrower claims securing specific embodiments.
Patent landscape surrounding 9,872,837
Key patent families and related patents
- The patent exists within a landscape of smaller patents and publications related to similar compounds or therapeutic methods.
- Filing dates and assignee networks suggest an active research area, likely competing with or building upon prior patents.
Competitive patents
Other patents likely include:
- Similar chemical entities with overlapping structures
- Method patents targeting the same indications
- Formulation patents aimed at stability, bioavailability, or delivery
Patent expiration and lifecycle
- Expiry date: August 29, 2037 (patents generally last 20 years from filing)
- Weeks into expiration: 14 years
- Opportunities for generics or biosimilars increase as the patent approaches its expiry unless extended or contested.
Analysis of patent enforceability and scope implications
- The linguistic scope and dependent claims are critical in litigation or licensing.
- Narrow claims limit the patent's enforceability but reduce design-around options.
- Broad claims provide leverage but face higher risk of invalidation through prior art.
