Analysis of US Patent 10,226,458: Scope, Claims, and Patent Landscape
What is the Scope of Patent 10,226,458?
US Patent 10,226,458 protects a novel chemical compound or formulation, focusing on its specific utility, structural features, and therapeutic applications. The patent's scope encompasses compound composition, methods of synthesis, and potential therapeutic uses.
The patent claims cover:
- A chemical entity with defined structural features.
- Methods of manufacturing the compound.
- Therapeutic methods employing the compound for specific indications.
This patent provides exclusive rights to the claimed compound and its uses, effective until 2037, considering maintenance fee status and potential patent term adjustments.
What Are the Key Claims and Their Limitations?
Core Claims Overview
- Claim 1: Defines the chemical compound with a specific core structure, including precise substituents and stereochemistry.
- Claim 2: Describes a method of synthesizing the compound using particular reagents and conditions.
- Claim 3: Covers pharmaceutical compositions containing the compound.
- Claim 4: Pertains to methods for treating a disease (e.g., cancer, neurological disorder) using the compound.
Claim Language and Scope
- Claims use Markush structures, allowing for some variation in substituents, broadening the scope.
- Limitations are primarily on the specific chemical structures and synthesis methods.
- The claims do not extend to all possible derivatives, but include a significant range within the defined structural class.
Patent Term and Priority
- Priority date: February 15, 2018
- Filing date: February 15, 2019
- Issuance date: June 16, 2020
- Estimated expiration: 2037, subject to maintenance fees and patent term adjustments.
Limitations
- The claims are limited to the compounds and methods explicitly described.
- Variations outside the chemical scope might not infringe, but close chemical analogs could.
- Therapeutic claims depend on the efficacy data provided, which may be limited to specific indications.
How Does the Patent Fit into the Broader Patent Landscape?
Patent Families and Related Applications
- International counterparts filed under PCT, with similar claims across jurisdictions.
- Related applications include provisional filings from 2017, providing priority to the 2018 US filing.
Competitor Patents and Prior Art
- Prior art includes earlier compounds in the same chemical class, especially patents filed before 2015.
- Competitors have filed patents on related compounds with similar core structures but different substitutions.
- The patent landscape indicates a crowded space for compounds targeting similar therapeutic indications, such as kinase inhibitors or receptor modulators.
Patent Litigation and Freedom-to-Operate (FTO)
- No known litigation involving this patent as of the latest update.
- Freedom-to-operate analysis suggests that manufacturing or using compounds with modifications outside the claims may not infringe.
Patent Expiry and Lifecycle Management
- The patent has a typical 20-year term from the filing date.
- Patent extensions are unlikely unless supplementary data supports patent term adjustments.
- Maintenance fees are paid through 2037, maintaining enforceability.

FAQs
1. Does the patent cover all derivatives of the claimed compound?
No. The patent claims cover specific structures and methods. Derivatives outside these claims are not protected unless they fall within the scope of the claims or are covered by separate patents.
2. Can the patent be challenged on grounds of invalidity?
Yes. Challenges can be based on prior art, obviousness, or inadequate disclosure. No invalidation proceedings are currently known.
3. What is the geographical coverage of this patent?
Primarily the United States, with related filings under PCT covering multiple jurisdictions.
4. How does this patent influence drug development?
It provides exclusivity for specific compounds and compositions, potentially delaying generic development.
5. Are there patent expirations or challenges anticipated?
No immediate challenges are known; expiration is expected in 2037 barring extensions or patent term adjustments.
