Analysis of U.S. Patent RE38919: Scope, Claims, and Patent Landscape
What Is United States Patent RE38919?
Patent RE38919 is a reissue patent granted by the United States Patent and Trademark Office (USPTO). Reissue patents address errors in original patents, typically expanding or clarifying the scope of the claims. RE38919 relates to a specific drug invention, with a focus on composition, formulation, or method of use. The reissue status indicates potential adjustments to broaden or rectify original claims.
What Is the Scope of Patent RE38919?
RE38919 covers a pharmaceutical compound, composition, or method, as indicated by its assigned claims. Its scope depends on the claims' language, which delineates the protected invention.
- Type of invention: Likely pertains to a drug formulation, a method of administration, or a specific use.
- Claims: The patent includes multiple claims, possibly both independent and dependent, defining the legal boundaries.
- Claims breadth: The independent claims specify core features, while dependent claims add specific embodiments or limitations.
- Claims example: An independent claim may cover "a pharmaceutical composition comprising X, Y, and Z," while dependent claims specify concentration ranges or dosing techniques.
What Are the Key Claims?
Without access to the exact claim language, standard practice suggests:
- Core claim: A pharmaceutical composition comprising a specified active ingredient, possibly with excipients, stabilizers, or delivery agents.
- Method claims: Use of the composition for treating a disease or condition.
- Formulation claims: Specific forms such as tablets, capsules, injections, or controlled-release systems.
The patent likely emphasizes specific chemical structures or formulations, with claims tailored to prevent others from making, using, selling, or importing similar drugs within the scope.
How Does the Patent Landscape Look?
The patent landscape surrounding RE38919 involves related patents, patent applications, and licensing agreements. Key considerations include:
Related Patents and Applications
- Parent Patent: RE38919 reissues a prior patent, which might have had narrower claims or errors now corrected.
- Prior Art: The landscape may include earlier patents on similar compounds, formulations, or therapeutic methods.
- Subsequent Patents: Ongoing innovations could include improvements or new uses stemming from the original patent.
Patent Classification and Citations
- International Patent Classification (IPC): The patent likely falls within classes related to pharmaceuticals, drug compositions, or delivery systems.
- Citations: Cited patents include prior art that defines the boundaries. Forward citations indicate potential influence on subsequent innovations.
Geographic Scope and Patent Families
- Domestic Patents: RE38919 is U.S.-specific; however, international counterparts may exist through filings under Patent Cooperation Treaty (PCT) or EuroPCT systems.
- Patent Families: Related filings across jurisdictions can extend the patent's protective scope globally.
Patent Status and Lifecycle
- Reissue Status: Indicates correction, possibly affecting enforceability or validity.
- Expiration: The patent's term typically lasted 20 years from filing; reissue patents can sometimes extend or adjust this period.
- Licensing and Litigation: The patent's strength lies in enforceability; patent litigation or licensing can influence its commercial significance.

FAQs
1. How does reissue status affect the enforceability of RE38919?
Reissue patents can clarify or broaden claims, but if alterations are significant, they might impact enforceability until the patent is examined and upheld by courts.
2. Can competitors develop similar drugs around this patent?
Potentially, if they design compounds or use methods outside the scope of claims, such as different active ingredients or alternative formulations.
3. Are there international equivalents of RE38919?
Likely, through patent families filed under PCT or regional systems. These extend protection outside the U.S. but require separate examination.
4. How does claim scope influence patent litigation risk?
Broader claims increase the risk but also provide more extensive protection; narrower claims reduce infringement risk but may be easier to design around.
5. What is the typical lifespan of a drug patent like RE38919?
Approximately 20 years from the earliest filing date, with possible adjustments depending on patent term extensions, provisional filings, or reissue status.
