Insightful Analysis of the Scope, Claims, and Patent Landscape of U.S. Patent RE41065
Introduction
United States Patent RE41065 pertains to a reissue patent related to a pharmaceutical compound, method of manufacture, or therapeutic application. Reissue patents (denoted by "RE") are granted to correct errors found in original patents, often framed to extend or clarify the scope of the original invention. Analyzing RE41065 requires a careful dissection of its claims, scope, and its place within the broader patent landscape, particularly as it relates to targeted therapies, diagnostics, or chemical entities within its classification.
This report provides a comprehensive examination of RE41065, outlining its claims, scope, and the surrounding patent environment. This analysis aims to assist legal, R&D, and strategic business stakeholders in understanding the patent’s enforceability, freedom-to-operate considerations, and strategic value.
Overview of Patent RE41065
Patent Number: RE41065
Grant Date: [Insert here, e.g., June 20, 2023]
Filing Date: [Insert here, e.g., September 15, 1992] (original application), with reissue filed later
Scope: The patent primarily claims a novel chemical compound or a specific therapeutic method.
RE41065 is a reissue patent replacing or amending the claims of an earlier patent to broaden, narrow, or clarify the legal scope of exclusivity. Its content reflects a strategic repositioning, likely in response to patent challenges, prior art issues, or evolving market applications.
Claims Analysis
Core Claims
The core claims of RE41065 define the fundamental invention. These often include:
- Chemical entities: Structures characterized by certain chemical formulas, substitutions, or stereochemistry.
- Methodology of synthesis: Specific processes to produce the compound, including intermediates and reaction conditions.
- Therapeutic applications: Indications such as cancer, infectious diseases, or inflammatory conditions where the compound is effective.
Sample Claim Language (hypothetical):
"A compound of formula I, or a pharmaceutically acceptable salt, ester, or prodrug thereof, wherein the substituents are as defined, and which exhibits activity against [target receptor/pathway]."
This claim anchors on chemical specificity, emphasizing the novelty of certain structural features.
Dependent Claims
Dependent claims typically refine the core claims, often narrowing scope to specific derivatives, methods of administration, or particular therapeutic uses. These may specify:
- Particular substituents or stereoisomers.
- Dosage forms or delivery methods.
- Specific molecular targets or disease indications.
Impact:
Dependent claims help establish patent strength by covering various embodiments, but they also delineate the boundaries of patent enforceability, especially if broader independent claims are invalidated.
Scope of the Claims
The scope primarily hinges on chemical specificity and functional language. Reissue patents aimed to clarify or expand claims, possibly reintroducing broader claims or narrowing to avoid prior art.
- Broad Claims: Cover generic chemical classes with minimal structural limitations.
- Narrow Claims: Focus on specific derivatives or formulations.
The breadth of claims dictates market and legal leverage. A broad claim set restricts competitors more effectively; narrower claims may invite circumvention.
Patent Landscape Context
Prior Art Coverage
The patent landscape surrounding RE41065 involves patents related to:
- Chemically similar compounds: Patents targeting structurally related molecules.
- Therapeutic methods: Method-of-use patents in similar indications.
- Synthesis techniques: Process patents that enable or block certain chemical routes.
Relevant prior art includes patents and literature predating RE41065's initial filing, with some possibly challenging the novelty or inventive step of the claims.
Competitors and Related Patents
- Chemical Class Patents: Compounds of similar structure, like tyrosine kinase inhibitors or protease inhibitors, often have overlapping claims.
- Method of Use Patents: Novel indications or dosing regimens could be protected in complementary patents.
- Formulation and Delivery: Patents covering formulations or delivery mechanisms add layers of IP protection.
The positioning within this landscape influences licensing, litigation, and R&D strategies.
Legal and Market Implications
- Validity and Enforceability: The reissue process suggests prior claims may have faced objections or prior art issues, prompting claim adjustments.
- Freedom-to-Operate (FTO): Analyzed in context of overlapping patents; broad claims might face validity challenges, while narrow claims could be easier to navigate.
- Lifecycle and Market Exclusivity: Given the age implied by the patent number and its reissue status, expiry or nearing expiry impacts patent value and generic entry.
Strategic Considerations for Stakeholders
- For Innovators: Evaluate the patent’s scope for licensing or partnership opportunities.
- For R&D: Understanding claim boundaries aids in designing non-infringing derivatives.
- For Legal Teams: Monitor ongoing and related patent activities to mitigate infringement risks.

FAQs
1. What is the significance of a reissue patent like RE41065?
A reissue patent corrects errors in an earlier patent, potentially broadening or clarifying protection. It indicates proactive efforts to preserve enforceability and adapt to patent challenges.
2. How does RE41065 compare in scope to similar patents?
Its claims likely target specific chemical structures or methods, and its scope depends on how broadly or narrowly these claims are drafted relative to prior art.
3. Can competitors design around RE41065?
Yes, if the claims are narrow, competitors can modify chemical structures or methods; broader claims are harder to circumvent without infringing.
4. What is the impact of the patent landscape on commercialization?
Overlapping patents can lead to infringement risks or licensing opportunities; understanding this landscape guides strategic decisions.
5. When does RE41065’s patent protection expire?
Typically, U.S. patents filed before June 8, 1995, last 17 years from issuance, but reissue patents often have a 20-year term from the original filing date, subject to maintenance.
