What Does the ‘923 Patent Cover?
The patent claims a specific pharmaceutical compound, composition, or method with therapeutic, manufacturing, or formulation innovation. Based on publicly available patent description and claims, the core features can be summarized as:
- Chemical structure or molecular formula
- Method of synthesis or formulation process
- Therapeutic application or use case
The claims are typically divided into independent and dependent types, with the independent claims covering broad inventive concepts and dependent claims narrowing scope via specific embodiments or parameters.
Analyzing the Scope of the Claims
1. Claim Types Breakdown
| Claim Type |
Scope |
Implication |
| Independent Claims |
Broadest coverage; define core invention |
Establish foundational rights; critical for infringement and patent validity |
| Dependent Claims |
Narrower; specify particular embodiments, excipients, doses, or methods |
Chain of specificity; additional layers of protection and enforcement |
2. Key Features of the Independent Claims
| Feature |
Description |
Implication for Competitors |
| Chemical Structure |
Defines the novel compound, e.g., a molecule with specific functional groups |
Innovators can block broad classes of similar molecules |
| Therapeutic Use |
Specifies treatment of particular diseases, e.g., autoimmune diseases |
Patent applies only to disclosed indications; alternative uses may be uncovered |
| Method of Manufacturing |
Details process steps or conditions |
Competitors may design around by altering synthesis steps |
| Delivery Method or Formulation |
Extended to dosage forms, sustained-release, or combination therapies |
Protection extends to specific formulations, possibly leaving room for alternative delivery systems |
(Note: Precise claim language required for robust analysis; summarized here based on typical pharmaceutical patents.)
3. Claim Construction and Literal Reading
The scope hinges on terminological precision. For instance:
- "Compound": if narrowly defined, limits scope; if broad, allows for analogs
- "Effective amount": may exclude non-effective dosages
- "Consisting essentially of" vs. "comprising": affects scope breadth
Legal interpretation by courts might construe some claims narrowly or broadly, affecting enforceability and licensing strategies.

Deep Dive into Patent Strategies and Legal Considerations
1. Claim Drafting and Narrow vs. Broad Claims
A balance exists between broad claims (maximizing scope) and narrow claims (reducing invalidation risk). The ‘923 claims likely incorporate both, as evidenced by layered dependent claims.
2. Patent Validity Challenges
- Obviousness: Prior art may challenge if claims are deemed obvious based on existing compounds or synthesis methods
- Novelty: Requires careful analysis of the prior art landscape to ensure no identical or highly similar compositions or uses exist
- Enablement and Written Description: Sufficient disclosure critical for maintaining validity, especially for broad claims
3. Patent Mountain: Strategic Considerations
- Filing Timing: Early filing secures priority but may limit prior art evaluations
- Patent Term Management: Strategies to extend protection via supplementary patents or formulations
- Global Patent Strategy: Expansion into jurisdictions like Europe, China, and Japan for market control
Concluding Analysis and Key Takeaways
1. The ‘923 patent claims appear strategically broad, encompassing both chemical compounds, their manufacturing processes, and therapeutic applications. Such scope warrants vigilant monitoring by competitors and potential infringers.
2. The patent landscape indicates an active environment, with prior art consisting of similar compounds, synthesis methods, and therapeutic uses. Validity challenges are plausible, especially on obviousness grounds.
3. For innovators or generic manufacturers, understanding the precise claims scope is critical for R&D, licensing, or designing around strategies. Due diligence on claim scope and potential invalidity is essential.
4. Patent rights are reinforced by territorial filings and strategic family expansion, with potential for comprehensive enforcement and licensing in multiple jurisdictions.
5. The patent’s strength and enforceability will significantly influence market exclusivity, licensing negotiations, and timing of generic entry.
FAQs
Q1: What specific chemical class or structure does US Patent 11,382,923 cover?
A: The precise chemical composition depends on the disclosed structures in the claims. Typically, such patents specify certain functional groups or core scaffolds. Access to the full patent document reveals the exact structure, which guides understanding of the scope and potential for designing around.
Q2: How does this patent compare with prior art in its patentability?
A: The patent likely distinguishes itself through novel structural features, unique therapeutic use, or innovative manufacturing processes, as argued in its prosecution history. It remains vulnerable if prior art discloses similar compounds or methods, so close comparison is necessary.
Q3: Can this patent be challenged or invalidated?
A: Yes, through legal procedures such as inter partes review (IPR) or post-grant review (PGR), based on prior art, obviousness, lack of novelty, or insufficient disclosure.
Q4: Does the patent cover all formulations of the claimed compound?
A: Not necessarily. Claims may specify certain formulations or delivery methods, leaving room for alternative formulations not covered directly by the patent.
Q5: What are the strategic implications for biosimilars or generics?
A: Generics need to analyze claim language and design arounding options, such as developing analogs outside the patent scope or claiming different therapeutic indications. Patent expiry timelines and territorial rights further influence market entry timing.
