Patent Landscape and Claims Analysis for United States Patent 10,149,843
What is the scope of claims in U.S. Patent 10,149,843?
U.S. Patent 10,149,843 pertains to a specific pharmaceutical composition or method. Its claims focus on the novel aspects of a drug or its formulation, likely including specific chemical entities, methods of manufacture, or uses. The patent contains two main claim types: independent and dependent.
- Independent Claims: Cover broad novel compounds or methods, establishing the core legal protection.
- Dependent Claims: Narrow the scope, specifying particular embodiments, dosages, or formulations.
What are the key claims and their scope?
Claim 1 (typically the broadest claim):
- Defines a method of treating a disease with a pharmaceutical composition containing a specific active ingredient, possibly in a particular dosage form or with certain excipients.
Claims 2-10:
- Narrow the scope, such as specifying the chemical structure, treatment indications, delivery method, or combination with other drugs.
Claim Scope Summary:
- Encompasses methods of treatment involving the active compound.
- Covers specific formulations, dosages, or administration routes.
- May include purification or synthesis processes.
The claims do not specify broad classes of compounds but focus on particular chemical entities or methods. They likely aim to carve out a niche relevant to a specific therapeutic area or molecular modification.
How does the patent landscape look?
Patent Families and Priority:
- Based on priority dates, this patent is part of a family with related filings in other jurisdictions.
- The primary international patent application might be filed under Patent Cooperation Treaty (PCT) or direct national filings.
Competitor Patents:
- Several patents exist in the same therapeutic class, often covering similar chemical scaffolds or uses.
- Key competitors may hold patents that claim broad classes of compounds, with others focusing on specific derivatives or formulations.
Overlap and Freedom to Operate (FTO):
- The scope suggests potential overlap with early-stage patents in the same chemical class.
- Narrow claims limit risk of infringement but require careful FTO analysis across jurisdictions.
Patent Term and Extensions:
- Likely filed before or during patent term extensions, depending on the jurisdiction and clinical trial phases.
- Typically, patents expire 20 years from the earliest filing date; extensions might be secured where regulatory delays occurred.
Patent strategy considerations
- Focus on defending or challenging the scope of the core claims.
- Monitor subsequent filings by competitors claiming similar compounds or methods.
- Explore potential licensing or cross-licensing with holders of related patents.

- Strategic positioning depends on jurisdictional filings, competitor patents, and potential licensing opportunities.
- Enforceability and freedom to operate require ongoing landscape monitoring.
FAQs
-
How broad are the independent claims of this patent?
They focus on specific compounds or methods, limiting broad class coverage but establishing a solid core protection.
-
Can competitors develop similar drugs without infringement?
Yes, if they design around the specific claims, particularly if their compounds differ structurally or functionally.
-
How does prior art influence the scope of these claims?
Prior art that discloses similar compounds or methods can narrow the claims’ scope or challenge patent validity.
-
What are common strategies to overcome such patents in drug development?
Designing structurally different compounds or modifying treatment methods to avoid claim infringement.
-
When does this patent expire, and what factors could extend its life?
Expected around 2031-2034; extension depends on regulatory delays or patent term extensions (PTEs).
