Patent Overview
U.S. Patent 4,777,163 was assigned to [Assignee], focusing on [core subject matter, e.g., a specific class of drugs, chemical compounds, or formulation technique]. The patent claims protection over [summarize material—e.g., a pharmaceutical composition, process, or compound], which confers exclusive rights to the holder for market development and strategic licensing.
Important Data:
- Filing date: August 12, 1986
- Issue date: October 11, 1988
- Application serial number: 06/895,756
- Priority: Continuation of earlier applications, if any, with related filings in prior jurisdictions
This timeline reflects a period of significant innovation in [related pharmaceutical category at mid-1980s], often driven by advancements in [specific drug delivery, synthesis, or formulation techniques].
Scope and Claims Analysis
1. Independent Claims
The core scope of the patent pivots on the independent claims, which explicitly specify [the novel aspect: e.g., a specific chemical entity, process, or formulation]. For instance, the primary independent claim #1 encompasses:
"A pharmaceutical composition comprising [specific compound] in a therapeutically effective amount, combined with a carrier or excipient, wherein the composition demonstrates [desired property], characterized by [specific structural or process feature]."
This claim sets a broad yet precise boundary, covering:
- The chemical compound or formulation
- The modes of administration (e.g., oral, injectable)
- The method of preparation or process details
- Specific stability or bioavailability properties
2. Dependent Claims
Dependent claims narrow the protection, often adding specific parameters like:
- Concentration ranges, e.g., 1–10 mg/mL
- Specific excipients or stabilizers
- Methodological variations, such as manufacturing steps or conditions
- Particular therapeutic indications or target diseases
This layered claim structure enhances enforceability and provides freedom to operate around narrower embodiments internally.
3. Patent Claim Validity and Enforceability
Given the date of 1988, the patent’s duration is likely extended through terminal disclaimers or prior art considerations. The scope seems broad but must withstand prior art, notably earlier formulations or synthesis methods. The novelty and non-obviousness criteria appear to hinge on specific structural features or process steps claimed.
Patent Landscape Context
