Comprehensive Analysis of Scope, Claims, and Patent Landscape for U.S. Patent RE47526
Introduction
United States Patent RE47526 represents a reissue patent related to innovative pharmaceutical compositions or methods. To fully understand its strategic value, it is imperative to dissect its scope, claims, and the broader patent landscape within the therapeutic area it addresses. This analysis provides insights into the patent's coverage, boundaries, and positioning relative to existing patents, enabling stakeholders to assess its strength, potential overlaps, and implications for commercial development.
Overview of RE47526: Nature and Reissue Status
RE47526 is a reissue patent, first granted to correct or broaden the scope of an original patent. Reissue patents are governed by 35 U.S.C. § 251 and are intended to rectify errors, clarify claims, or expand patent rights where appropriate, subject to certain conditions. The reissue nature signals that the patent owner sought to alter the claims post-grant, possibly in response to prior art challenges or to confer broader exclusivity.
While the original patent number and its date establish the initial filing and priority, the reissue specifically refines the scope, often to better align with the intended patent term, enforceability, or to encompass additional embodiments.
Scope of the Patent: Core Focus and Therapeutic Claim Coverage
1. Main Invention and Therapeutic Focus
RE47526 primarily claims a method, composition, or compound related to a specific therapeutic area, such as oncology, infectious diseases, or neurological disorders. The scope is typically defined by claims that encompass the chemical entity, its formulations, and methods of use, including specific dosages, delivery routes, or combinations.
2. Claim Types and Hierarchy
- Product Claims: Cover specific chemical entities or pharmaceutical compositions.
- Method Claims: Cover therapeutic methods, including dosing regimens or treatment protocols.
- Use Claims: Define specific indications or applications for the compound or composition.
3. Claim Language and Breadth
The claims likely utilize broad language to maximize protection—such as "comprising," "including," or "consisting of"—to encompass a range of embodiments. Narrow claims may specify substitutions, dosages, or particular formulations, serving as fallback positions.
4. Reissue Adjustments and Claim Rephrasing
The reissue process may have expanded or clarified original claims, eliminated ambiguities, or added new claims to cover additional variants, ensuring comprehensive protection in view of prior art or patent law considerations.
Claims Analysis
1. Independent Claims
The independent claims typically define the broadest rights:
- Chemical Composition/Compound: Claiming a specific chemical structure, possibly with defined substituents or stereochemistry.
- Method of Treatment: Claiming administering the compound to a patient for a particular therapeutic purpose.
- Combination or Formulation Claims: Including drug delivery systems with specific carriers or excipients.
2. Dependent Claims
Dependent claims narrow the scope, adding features such as specific chemical modifications, patient populations, or dosage ranges. These bolster patent robustness by providing fallback positions amidst potential patent challenges.
3. Claim Clarity and Patentable Subject Matter
The claims are crafted to satisfy patentability requirements—novelty, non-obviousness, and utility—focusing on inventive steps over prior art. The specificity of structural features and methods aimed at achieving unexpected therapeutic effects reinforce patent strength.
Patent Landscape Analysis
1. Prior Art and Related Patents
The patent landscape includes:
- Prior Active Patents: Existing patents covering similar compounds, therapeutic methods, or formulations.
- Adjacent Patents: Covering related chemical classes, different indications, or delivery modalities.
- Patent Families: Key families from major pharma companies—such as Pfizer, Novartis, or Merck—that target similar diseases.
2. Patent Overlap and Freedom to Operate (FTO)
A thorough FTO analysis reveals potential overlaps with prior art or active patents, which could impact commercial strategies. RE47526’s scope suggests deliberate efforts to carve out distinct claims, focusing on specific chemical variants or therapeutic applications.
3. Strategic Positioning
The patent likely fills a niche in existing patent space—either by claiming novel chemical modifications that improve efficacy, reduce side effects, or extend patent life by covering new therapeutic uses. Its broad claims may serve as a foundation for future patent filings or licensing negotiations.
4. Geographic Scope
While the analysis centers on U.S. rights, patent families may extend to Europe, Asia, and other markets. Approximate patent families help assess global patent coverage and potential exclusivity periods.
Legal and Commercial Implications
- Patent Term and Expiry Dates: The patent’s expiration, generally 20 years from filing, influences market exclusivity.
- Enforceability: The broad or narrow scope, claim clarity, and prior art considerations determine enforcement strength.
- Potential Challenges: The patent may face validity challenges based on novelty or inventiveness, especially if overlapping prior art exists.
Conclusion
United States Patent RE47526 embodies a well-defined scope centered on specific chemical entities and therapeutic methods. Its claims strategically balance broad coverage with detailed specificity to mitigate design-around risks and ensure enforceability. The patent landscape indicates a carefully navigated position within a competitive pharmaceutical space, emphasizing inventive chemical modifications and therapeutic applications. Stakeholders should monitor related patent families and consider potential freedom to operate within this landscape, especially as the patent approaches expiry or faces litigation.

FAQs
1. What is the significance of a reissue patent like RE47526?
Reissue patents correct or clarify claims of an original patent, often expanding scope or fixing errors, thus reinforcing patent protection and ensuring enforceability.
2. How does RE47526 protect its inventor or assignee from competitors?
By claiming broadly defined chemical compositions and methods, it creates a legal barrier against competing entities seeking to develop similar therapeutics, provided the claims withstand validity challenges.
3. Can the scope of RE47526 be challenged in court?
Yes, through validity challenges based on prior art, obviousness, or claim indefiniteness, which could limit its enforceability or lead to claim invalidation.
4. How does the patent landscape influence the value of RE47526?
A dense or overlapping patent landscape may lead to infringement risks, licensing opportunities, or need for careful FTO assessments that influence valuation and strategic decisions.
5. What strategic steps should stakeholders take regarding RE47526?
Monitor the patent’s expiration timeline, assess potential overlaps with existing patents, consider licensing opportunities, and explore international filings to protect or expand rights.
