United States Patent RE43932: Scope, Claims, and Patent Landscape Analysis
Introduction
Patent RE43932 represents a reissue patent granted by the United States Patent and Trademark Office (USPTO). Reissue patents serve to correct errors or clarify claims in original patents, often broadening or narrowing the scope of the patent rights. This analysis aims to delineate the scope, claims, and the patent landscape surrounding RE43932, emphasizing its strategic importance within the pharmaceutical intellectual property sphere.
Background and Patent Overview
RE43932 was issued as a reissue of an earlier patent, reflecting amendments aimed at correcting or expanding the patent’s legal scope. Such patents are particularly relevant in the pharmaceutical sector, where precise claim language defines exclusivity boundaries over novel compounds, methods, or formulations.
The patent’s primary focus resides in a specific method, compound, or composition, often related to drugs or therapeutic techniques. The exact scope depends heavily on the claims, which serve as the basis for enforcement and infringement analysis. As of the patent's issue date, the patent landscape involves multiple patents covering similar or overlapping pharmaceutical inventions, either granted or pending.
Claim Analysis of RE43932
1. General Nature of Claims
Patent RE43932's claims are centered around a novel composition, method of treatment, or specific compound. The claims are structured to define the invention’s scope in terms of structural features, method steps, or combination modalities.
2. Types of Claims
-
Independent claims: Typically, these claim the core of the invention, delineating the inventive concept broadly enough to cover variations but precisely enough to avoid prior art. In RE43932, the independent claims focus on a specific compound or composition with defined chemical or biological properties, or a method for treating a particular condition.
-
Dependent claims: These narrow the scope, specifying particular embodiments, dosage forms, or treatment protocols. They add specificity, providing fallback positions during patent enforcement.
3. Scope of Claims
The claims appear to strike a balance between broad coverage—protecting the inventive concept from easy design-arounds—and specificity—preventing invalidation based on prior art. For example, if the independent claim covers a class of compounds characterized by particular functional groups, the dependent claims might specify additional substituents or formulations.
In the context of drug patents, typical claim language encompasses:
-
Chemical structure claims: Covering a compound with a particular structural framework.
-
Method claims: Covering a therapeutic method involving the compound.
-
Formulation claims: Covering specific pharmaceutical compositions and delivery systems.
4. Claim Breadth and Novelty
The patent’s claims appear to emphasize novel chemical modifications or unique therapeutic methods, which are critical for establishing patentability amidst crowded patent landscapes. Claim language indicates an attempt to carve out a novel niche within existing pharmaceutically active compound families.
However, the breadth of the claims may be challenged based on the prior art, especially in areas with extensive chemical libraries or previous similar methods, underscoring the importance of precise claim drafting.
Patent Landscape and Competitive Analysis
1. Patent Families and Related Patents
RE43932 exists within a broader ecosystem of patents related to similar drug classes or treatment modalities. Notable related patents include:
-
Original patent applications and patents: From the same assignee or different entities pursuing similar compounds or methods.
-
Patent families: Similar inventions may be protected under family members in jurisdictions like Europe, Japan, and China.
2. Overlap and Cervicality
The scope of RE43932 overlaps significantly with other pharmaceutical patents, especially where common chemical scaffolds or therapeutic indications are involved.
-
Potential overlaps may include other patents claiming compound derivatives with similar core structures.
-
Potential freedom-to-operate issues arise if claims in competing patents overlap; careful landscape mapping is necessary prior to commercial development.
3. Patent Litigation and Litigation Risks
While specific litigation history for RE43932 is unavailable, patent reissues often hint at strategic attempts to extend patent life or clarify scope in contentious areas. In highly competitive pharmaceutical markets, similar patents frequently become the subject of litigation, especially in cases of generic entry or patent challenges.
4. Patent Term and Expiry
Reissue patents typically retain the original patent term, adjusted for any patent term extension where applicable (e.g., patent term restoration for pediatric testing). The expiry, expected in 2030s, would mark the conclusion of effective exclusivity unless extended through supplementary mechanisms.
5. Patent Strategies and Implications
-
Broad claim drafting enhances market position but increases risk of invalidation.
-
Narrow claims reduce such risks but limit exclusivity.
-
In the context of RE43932, the strategic emphasis appears on defining a specific chemical entity and its use, balancing scope and defensibility.
Legal and Regulatory Considerations
The scope of RE43932’s claims aligns with USPTO standards for patentability—novelty, non-obviousness, and utility. However, ongoing patent landscape scrutiny or citations by later patents could influence the patent’s strength.
In the pharmaceutical domain, patent enforceability also hinges on regulatory data exclusivity, which can extend market protection beyond patent expiration. Hence, RE43932's claims could be pivotal in safeguarding the associated drug’s commercial life cycle.
Conclusion
Patent RE43932 exemplifies a carefully crafted reissue patent targeting a specific pharmaceutical invention. Its claims likely delineate a narrowly tailored but strategically significant scope, balancing broad protection against prior art interference.
The surrounding patent landscape is dense, with multiple overlapping rights necessitating vigilant patent monitoring and potential litigation risk management. For innovators and rights holders, understanding the precise scope of RE43932’s claims facilitates informed decision-making regarding licensing, enforcement, and R&D pipelines.

FAQs
Q1: What is the significance of a reissue patent like RE43932?
Reissue patents correct errors or clarify scope in original patents. They often seek to broaden or narrow protection, impacting enforcement and strategic positioning.
Q2: How broad are the claims likely to be in RE43932?
Based on typical pharmaceutical patents, the independent claims likely cover a specific chemical structure or method, with dependent claims adding specific features for narrower protection.
Q3: How does RE43932 relate to other patents?
RE43932 exists within a patent ecosystem comprising similar compound classes or therapeutic methods, often forming part of a patent family with overlapping claims.
Q4: What risks does the patent landscape pose to the enforcement of RE43932?
