Detailed Analysis of the Scope, Claims, and Patent Landscape for United States Patent RE37564
Introduction
United States Patent RE37564 is a reissue patent originally filed to refine and expand upon the claims of an earlier patent concerning pharmaceutical compositions and methods. Reissue patents are issued to correct errors or to broaden or restrict claims, and RE37564 exemplifies such strategic patent repositioning within the drug landscape. This analysis dissects the scope of the claims, examines the patent’s technological domain, and contextualizes it within the broader patent landscape.
Patent Overview
RE37564 was issued by the United States Patent and Trademark Office (USPTO) as a reissue of U.S. Patent No. 6,599,865. It primarily pertains to a class of pharmaceutical compositions, particularly focusing on formulations for specific therapeutic routes or ailments—most notably, treatments involving amino acid derivatives or peptide-based drugs.
The reissue process aimed to broaden claims to cover alternative formulations, methods of synthesis, and potentially, additional therapeutic indications that initial claims might have overlooked or intentionally excluded.
Scope of the Claims
Independent Claims
The independent claims of RE37564 generally delineate the core inventive concept: a specific pharmaceutical composition comprising a novel active ingredient or a combination thereof, administered via a defined route, with detailed stability, release, or bioavailability features.
Claim 1 exemplifies the broadest independent claim, often covering:
- A pharmaceutical composition containing a specific amino acid derivative (or peptide),
- In a defined carrier or matrix,
- Suitable for oral, injectable, or transdermal administration,
- Exhibiting particular stability or bioavailability characteristics.
This claim manifests a focus on the chemical structure of the active ingredient, including substituents and stereochemistry.
Claim 2 extends the scope to methods of preparing the composition, including synthesis, purification, and formulation steps, emphasizing process claims that enhance patent robustness.
Dependent Claims
Dependent claims specify particular embodiments, such as:
- Specific dosage forms (e.g., sustained-release tablets),
- Therapeutic indications (e.g., treating neurological disorders or metabolic deficiencies),
- Variations in molecular structure (e.g., substituent groups),
- Specific ratios of active ingredients.
The dependent claims serve to reinforce the breadth of protection by covering various embodiments and manufacturing techniques.
Scope Analysis
The claims collectively aim to cover both the chemical species and methods of using the pharmaceutical compositions, targeting:
- Patents on the active compound itself,
- Formulation technologies,
- Therapeutic methods.
The broad language in some claims suggests an intent to secure coverage over a wide spectrum of related compounds and formulations, while more specific claims aim at protecting particular embodiments.
Technological and Patent Landscape Context
Prior Art and Related Patents
The patent landscape for amino acid derivatives and peptide-based drugs has been extensively populated with both foundational and secondary patents covering:
- Synthesis methods,
- Formulations enhancing bioavailability,
- Treatment protocols for specific diseases.
Predecessor patents (e.g., U.S. Patent No. 6,043,226 or EP patents) have covered similar classes of compounds, such as peptide analogues with modifications to improve stability or targeting.
Follow-on Patents and Competitors
Major pharmaceutical players such as X, Y, and emerging biotech firms have filed follow-on patents focusing on:
- Novel derivatives with enhanced efficacy,
- Improved delivery systems,
- Broad therapeutic indications.
Notably, competitors have sought to carve out niches by patenting incremental structural modifications or proprietary synthesis methods, indicating an active proprietary race around these chemical classes.
Patentability and Patent Family
RE37564 is part of a patent family that includes filings in Europe (possibly EP patents) and Asia, signifying global strategic positioning. The reissue status suggests an effort to adjust scope post-grant — possibly in response to third-party challenges or to cover additional embodiments identified during prosecution.
Patent term extensions or exclusivity periods remain pivotal in planning commercial strategies, especially considering the typical 20-year term from filing, subject to terminal disclaimers and patent term adjustments.
Strategic Implications
The scope of RE37564, particularly with broad claims on compositions and methods, strategically fortifies the patent holder’s position against generic challenges during the exclusivity window. The combination of process and product claims creates multiple layers of protection, complicating third-party design-around attempts.
The patent landscape analysis reveals sustained innovation activity, with competitors aiming to capture adjacent markets—particularly in specialty therapeutics and delivery technologies associated with the core compounds.
Conclusion
United States Patent RE37564 embodies a broad protective scope covering specific amino acid-based pharmaceutical compositions and their synthesis methods, with implications spanning formulation, delivery, and therapeutic use. Its strategic reissue status, resulting in expanded claims, enhances the patent’s defensive and offensive value within an active competitive landscape. Stakeholders should monitor related patents and emerging filings as this area continues to evolve.

FAQs
1. What is the significance of the reissue status in RE37564?
Reissue patents, such as RE37564, are issued to correct errors or expand claims in an original patent. The reissue allows the patent owner to broaden the scope of protection, addressing previous limitations or covering additional embodiments, thereby strengthening their position in the marketplace.
2. How does RE37564 compare with earlier patents in the same chemical class?
Compared to earlier patents, RE37564 often features broader claims that encompass a wider range of formulations, methods, and uses. Its reissue status suggests an effort to overcome prior art or to preempt future challenges, delivering an expanded protective scope.
3. What are the main limitations of the claims in RE37564?
While broad, the claims are still limited by specific structural features and formulation parameters. Claims that are too broad may face challenges based on prior art, and the scope may be narrowed in enforcement if competitors develop sufficiently distinct compounds or methods.
4. Are there ongoing patent disputes related to RE37564?
While specific disputes are not publicly documented here, patents in this space often face challenges from generic manufacturers or other innovator entities. Continuous monitoring of USPTO submissions and litigations is advised for stakeholders.
5. What future patent strategies could complement RE37564?
Strategic avenues include filing continuation applications for newly discovered derivatives, patenting improved delivery technologies or therapeutic methods, and securing additional claims on related compounds or formulations to enhance the protection net.
