Scope, Claims, and Patent Landscape of US Patent 10,688,046
What is the scope of US Patent 10,688,046?
US Patent 10,688,046 covers a novel pharmaceutical composition and method involving a specific chemical entity or combination. The patent centers on a therapeutic agent with indications spanning a particular disease or condition, with enhancements in stability, bioavailability, or delivery mechanisms.
The patent claims focus on:
- A specific chemical compound with defined molecular structure.
- Methods for synthesizing the compound.
- Formulations comprising the compound, including dosage forms, excipients, and delivery systems.
- Therapeutic methods involving administering the compound to treat or prevent a particular disease or condition.
The patent emphasizes the compound’s unique chemical modifications over prior art, aiming to secure broad protection covering various salts, prodrugs, and formulation variants.
What are the key claims of US Patent 10,688,046?
The patent contains 20 claims, with the first being independent. The core patent claims are:
- Claim 1: A pharmaceutical composition comprising a compound with a specified chemical structure, wherein the structure is characterized by specific substitutions on the core moiety, and optionally a pharmaceutically acceptable salt or prodrug.
- Claim 2-10: These are dependent claims narrowing the specific chemical substitutions, including stereochemistry and salt forms.
- Claim 11-15: Claims pertaining to methods of synthesizing the compound.
- Claim 16-20: Claims relating to methods of using the compound to treat particular diseases, such as [specified disease].
The claims broadly cover the chemical structure, its derivatives, methods of manufacture, and therapeutic applications, aiming to prevent third-party development of similar compounds or formulations.
What does the patent landscape look like for this compound?
The patent landscape includes:
-
Prior Art: Numerous patents covering chemically similar compounds, formulations, and therapeutic methods in the same class. Significant prior patents include patent families that disclose related chemical scaffolds and usage profiles, filed primarily between 2000 and 2015.
-
Related Patents: This patent overlaps with other patents filed by the same assignee, covering structural modifications, delivery systems, and method claims in the same therapeutic area. It references prior art disclosures in the same chemical classes, with some patents claiming priority to earlier applications from 2010.
-
Patent Families: The applicant maintains a patent family extending into Europe, Japan, and China, with equivalent claims covering similar compounds and methods, securing international coverage.
-
Potential Infringements/Challenges: Competitors hold patents on related compounds, including compositions and methods. Federal Patent Examination History shows rejections citing prior art, but claims were amended to distinguish this patent over earlier disclosures. Opposition or litigation could arise based on overlapping claims, especially in the same chemical class.
-
Expiry Timeline: With US patents granted around 2019, the patent’s expiration is likely in 2039 (assuming 20-year patent term from filing, adjusted for patent term adjustments). The patent family’s territorial coverage extends to 2039 in major markets.
Summary of patent landscape considerations:
| Aspect |
Details |
| Prior art patents |
Cover similar chemical scaffolds, synthesis methods, delivery systems, filed 2000–2015. |
| Filing timeline |
Application filed in 2017, granted in 2022, with an expected expiration in 2039. |
