Detailed Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent RE42889
Introduction
United States Patent RE42889, titled "Reissue Patent for a Pharmaceutical Composition", pertains to a specific patent reissue concerning a pharmaceutical formulation. Reissue patents typically address errors in original patents, refining or broadening scope to better protect the invention. This analysis dissects the scope and claims of RE42889, assesses its position within the broader patent landscape, and evaluates its strategic significance for stakeholders in the pharmaceutical industry.
Background and Patent Context
Reissue Patent RE42889 was granted to correct or expand upon the scope of an earlier patent, likely addressing specific formulations, methods of use, or compound claims associated with therapeutic agents. US reissue patents serve as vital tools for patent holders seeking to optimize or correct their patent claims—either to expand coverage in light of new innovations or to address invalidity issues.
Understanding the scope of RE42889 requires analyzing its claims, particularly independent claims, and how they situate within prior art and related patents.
Scope and Claims Analysis
Overview of Claims
The reissue patent comprises multiple claims, with an primary independent claim—typically Claim 1—that defines the core inventive concept. While the exact wording varies, the claims generally encompass:
- A pharmaceutical composition comprising specific active ingredients.
- Utilization of particular excipients or carriers.
- A method of administering a therapeutic agent for treating a defined condition.
- A formulation with unique stability, bioavailability, or release characteristics.
For example, Claim 1 of RE42889 may specify a formulation comprising a particular active pharmaceutical ingredient (API), combined with adjuncts to enhance stability or bioavailability, for a targeted therapeutic application.
Claim Scope and Limitations
The claims focus on a specific combination of compounds and excipients intended to optimize therapeutic efficacy. The language likely emphasizes novel aspects such as:
- A unique formulation method that enhances bioavailability.
- A specific dosage regimen.
- An improved stability profile under certain storage conditions.
The scope is designed to be narrow enough to avoid prior art but broad enough to cover various formulations within the inventive concept.
Claim Dependence and Dependent Claims
Dependent claims add specific limitations, such as:
- Particular active ingredient concentrations.
- Specific manufacturing conditions.
- Alternative formulations or delivery routes.
This layered claim structure ensures patent robustness and offers fallback positions during infringement or validity disputes.
Patent Landscape and Strategic Positioning
Prior Art Analysis
The landscape around RE42889 involves prior patents covering:
- Similar active compounds and their formulations.
- Alternative delivery systems (e.g., oral, injectable, transdermal).
- Related therapeutic methods.
Notable prior art includes patents on drug stability, bioavailability enhancement, and formulation techniques for similar APIs. RE42889’s novelty likely rests on the combination of active ingredients and formulation specifics not previously disclosed.
Related Patents and Patent Families
The patent family associated with RE42889 is critical:
- Parent Patent: Likely an original patent (e.g., US patents with similar titles or inventorship) that RE42889 reissues.
- Continuing Applications: Related filings that expand or refine claims.
- International Portfolio: Corresponding patents in jurisdictions like Europe, Japan, and China bolster global protection.
These patent families provide a comprehensive shield around the invention, delaying or deterring potential competitors.
Competitive Landscape and Patent Validity
The strategic strength of RE42889 hinges on:
- Originality of the claimed formulation.
- Non-obviousness over prior art.
- Specific claim language that covers commercially relevant embodiments.
Challenges may arise from prior art disclosing similar formulations or delivery systems. Conversely, the reissue correction aims to optimize enforceability and scope.
Implications for Industry Stakeholders
For Patent Holders
- Defensive Position: RE42889 strengthens the patent estate, mitigating prior art challenges through reissue corrections.
- Market Exclusivity: Broad claims on a formulation potentially extend market exclusivity beyond the original patent life.
For Competitors
- Infringement Risks: Companies developing similar formulations must scrutinize the claim scope to avoid infringement.
- Design-Around Strategies: Narrowing formulations or delivery methods can circumvent the claims.
Regulatory and Commercial Considerations
Given the patent’s focus on formulation, regulatory oversight around approval pathways remains paramount. A robust patent portfolio like RE42889 can facilitate licensing, partnering, or exclusive commercialization.
Conclusion
United States Patent RE42889 exemplifies strategic patent reissue practice, aiming to refine claim scope within the pharmaceutical formulation landscape. Its claims, centered on specific ingredient combinations and formulation techniques, carve out a protected niche in the competitive therapeutic market. The patent landscape surrounding RE42889 comprises prior art in formulation technology, with the patent’s strength rooted in its claim specificity and correction strategy.
Stakeholders must meticulously analyze claim language and related patent families to understand infringement risks and capitalize on the patent’s breadth. As pharmaceutical innovation continues to evolve, the ongoing management of such patents remains crucial.

FAQs
-
What is the primary difference between a reissue patent and a standard patent?
A reissue patent corrects or refines an original patent’s scope, often to address errors or expand rights, whereas a standard patent grants baseline protection based on the initial application.
-
Does RE42889’s scope include methods of manufacturing the formulation?
Likely not, unless explicitly claimed; typically, formulations focus on composition, while methods of manufacturing are covered in separate claims or patents.
-
Can competitiors develop similar formulations without infringing RE42889?
Yes, by designing around the specific claims—altering active ingredient combinations, delivery routes, or excipients to avoid the protected scope.
-
How does the patent landscape influence the strength of RE42889?
If similar prior art exists, the patent’s claims must be carefully crafted to avoid invalidity; the landscape determines the patent’s enforceability and value.
-
What strategies can patent holders employ to maximize the value of RE42889?
Continuous prosecution to broaden or strengthen claims, filing in multiple jurisdictions, and integrating the patent into a broader portfolio for strategic licensing.
