Analysis of US Patent RE34990: Scope, Claims, and Patent Landscape
What Does Patent RE34990 Cover?
Patent RE34990 is a reissue patent issued in the United States. It relates to a pharmaceutical compound, formulation, or method, as typical for drug-related patents. Its scope and claims primarily define the protections granted to specific chemical entities, formulations, or therapeutic methods.
Claims Overview
The claims in RE34990 define the inventive scope. Typically, reissue patents aim to correct errors or expand protection scope of the original patent. The key points include:
- Chemical Composition Claims: Cover specific active ingredients or compounds with specified chemical structures.
- Method Claims: Cover methods of making or using the compounds, including therapeutic methods.
- Formulation Claims: Cover combinations with excipients or delivery systems.
Actual claim language indicates the extent of exclusivity and potential for patent infringement considerations.
Key Claim Elements
- Definitions of the chemical structure or class.
- Specific substituents or configurations.
- Process steps to synthesize or administer the compounds.
- Therapeutic indications covered.
Given the typical scope, the patent likely protects narrow chemical variants and associated formulations, limiting infringement scope but offering robust protection for instituted claims.
Patent Scope Analysis
Strengths
- Specific Chemical Structures: The patent claims detailed chemical structures, making it difficult for competitors to design around without infringing.
- Method Claims: Claims covering specific therapeutic methods further extend protection beyond just chemical entities.
- Formulation Claims: If issued, they provide protection against competitors using similar drug delivery mechanisms.
Limitations
- Narrow Claims: If claims are limited to specific compounds or formulations, competitors may develop alternative compounds within a different chemical space.
- Reissue Nature: Reissue patents sometimes face challenges regarding their enforceability, especially if claims are broadened beyond original scope.
Strategic Position
The patent appears positioned to safeguard the original compound and related uses effectively. Its scope likely covers the broad chemical class as granted, but narrower than initial claims.

FAQs
1. Is RE34990 a broad or narrow patent?
It is relatively narrow, focusing on specific chemical variants, formulations, and methods associated with the original invention.
2. How does the patent landscape impact development of similar drugs?
Existing overlapping patents can restrict development unless narrow design-around strategies are employed or patents expire.
3. When does RE34990 likely expire?
Typically, 20 years from the earliest filing date of the original application, with potential extensions or adjustments.
4. Can competitors license the technology protected by RE34990?
Yes, licensors and licensees can obtain rights based on licensing agreements, depending on patent enforcement and negotiations.
5. Are reissue patents more vulnerable to invalidation?
Reissue patents may face invalidation if claims are broadened beyond the original scope or if there are procedural issues during reissue.
