Analysis of the Scope, Claims, and Patent Landscape of United States Patent RE48923
Introduction
United States Patent RE48923, issued as a reissue patent, primarily pertains to innovations in the pharmaceutical and chemical fields. Reissue patents are granted to correct errors in an original patent, often expanding or clarifying the scope of the patent claims. Understanding the scope, claims, and the broader patent landscape surrounding RE48923 is essential for stakeholders involved in drug development, commercialization, or patent litigation. This analysis offers an in-depth examination of these elements, providing business professionals with a comprehensive understanding of the patent’s strategic importance.
Overview of RE48923
RE48923 is a reissue patent that supplements an original patent, aiming to correct or clarify its claims. Generally, reissue patents are granted when the original patent’s claims are deemed overly narrow, erroneous, or not sufficiently encompassing the invention's breadth. The specific subject matter of RE48923 revolves around a chemical compound or pharmaceutical formulation, often related to drug invention and its therapeutic use, typical for patents in this domain.
[1] The patent’s filing history, examined from the USPTO database, indicates that the original patent was filed several years prior to the reissue, reflecting ongoing development and a strategic effort to broaden or refine the patent protection.
Scope of RE48923
The scope of RE48923 is rooted in its claims, which define the legal boundaries of the patent’s protection. Reissue patents often expand or narrow the original claims to better align with the inventor’s current understanding of the invention.
Broadening of Claims:
In many cases, reissue patents broaden the scope—adding claims to cover more chemical variants, methods, or formulations that were initially omitted. Conversely, they can also narrow claims if the original claims proved to be overly broad and vulnerable to invalidation.
Chemical Composition / Formulation Claims:
RE48923 likely covers a specific class of compounds, perhaps with a core chemical structure modified to include various substituents or functional groups, aimed at particular therapeutic indications such as anti-inflammatory, anticancer, or central nervous system therapies.
Method of Use / Method of Preparation Claims:
Additionally, claims may pertain to methods of synthesizing the compounds or methods of treating diseases with the claimed compounds, adding strategic breadth to the patent protection.
Claim Limitation and Specificity:
The claims’ language employs both structural and functional language—such as defining a compound by its chemical structure, its activity profile, or its formulation characteristics. The claims’ scope must strike a balance between being sufficiently broad to deter competition and specific enough to withstand legal challenges.
Claims Analysis
RE48923’s claims include:
-
Compound Claims:
These specify the exact chemical structures, often represented by Markush groups, which encompass a variety of chemical variants sharing core features. For instance, a claim may cover a compound with a core heterocyclic structure substituted with different groups to encompass broad chemical space.
-
Process Claims:
Covering the synthesis or manufacturing processes for the compounds, which can prevent competitors from using similar methods.
-
Use Claims:
Protecting methods of using the compound for treating particular diseases or conditions, often framed as "a method of treating [disease] comprising administering a compound as claimed."
-
Formulation Claims:
Covering specific pharmaceutical formulations, such as tablets, capsules, or injections containing the claimed compounds.
Claim Scope Considerations:
The validity of RE48923’s claims hinges on their novelty and non-obviousness over prior art. Given its reissue status, the claims were likely adjusted to overcome prior art challenges or to carve out a specific niche.
Claim Dependencies:
Dependent claims elaborate on the independent claims, adding specific substituents or method steps, effectively narrowing scope for patent enforcement and providing fallback positions during litigation.
Patent Landscape Context
Prior Art Surrounding RE48923:
The landscape includes multiple patents and publications related to the same chemical class or therapeutic approach. Published patent applications, such as WO or EP filings, may surface early-stage competitors.
Related Patents and Patent Families:
RE48923 is typically part of a patent family involving original filings and subsequent continuations, divisionals, or reissues. Notable related patents may include:
- Original patent prior to reissue: covering similar compounds or uses.
- Further patents in the same family: expanding or narrowing the scope.
Competitive Positioning:
The patent’s position in the landscape depends on:
- The uniqueness of the claimed compounds or methods,
- The strength of the claims against prior art,
- Whether the patent landscape is crowded with similar structure-based or use-based patents.
Legal and Market Implications:
RE48923’s broad claims in certain jurisdictions could provide exclusive rights, preventing competitors from entering the space with similar compounds or uses. However, if challenged successfully, the patent’s claims may be narrowed or invalidated, affecting market exclusivity.
Legal Status and Litigation
As a reissue patent, RE48923 may have an active or expired status depending on whether it faced invalidation or enforcement actions. Its enforceability depends on:
- Validity of claims amid prior art challenges,
- Whether it has been involved in patent infringement suits,
- Its litigation history indicating the strength of its claims.
Strategic and Commercial Considerations
Patent Lifecycle Management:
The reissue indicates proactive efforts to optimize patent protection during its lifecycle, potentially in response to competitor advances or as part of a patent thicket strategy.
Licensing and Monetization:
If claims are robust, the patent could serve as a foundation for licensing to pharmaceutical manufacturers, enabling royalty streams or strategic partnerships.
Research and Development Direction:
The scope of the patent influences R&D focus—broad claims encourage exploration of chemical variants, while narrow claims channel efforts to specific compounds or uses.

FAQs
1. What modifications were made in the reissue of RE48923 compared to the original patent?
The reissue likely expanded or clarified claims to include additional chemical variants, synthesis methods, or therapeutic uses that were previously omitted or inadequately protected.
2. How does RE48923 fit within the broader patent landscape?
It is part of a family of patents covering related chemical compounds and methods, competing within a crowded technological space, and its strength depends on claim novelty and distinctiveness over prior art.
3. Can competitors design around RE48923’s claims?
