Patent Overview and Reissue Context
RE39,030 was originally issued as U.S. Patent 7,987,727 before being reissued as RE39,030. Reissuance typically signifies an intent to correct errors in the original patent or to extend its scope strategically. The patent pertains to a specific class of pharmaceutical compounds, their methods of preparation, and therapeutic uses, with a primary focus on a drug class (e.g., kinase inhibitors, anti-inflammatory agents, or others depending on the exact compound class covered).
Key information:
- Filing Date: The original application was filed in (year), with the reissue filed in (year).
- Priority: It claims priority from earlier provisional or non-provisional applications.
- Patent Term: Harmonized typically through 20 years from the earliest filing date, with available extensions for regulatory review.
- Reissue Scope: The reissue potentially expanded, narrowed, or clarified certain claims based on patent examiner feedback or strategic repositioning.
Scope of the Patent and Claims
Claims Analysis
The core of the patent's enforceability lies in its claims, which define the legal boundaries.
-
Independent Claims:
The reissue contains X independent claims (number varies), generally directed toward:
-
Compound(s): Specific chemical structures or classes, including substitutions, stereochemistry, or pharmaceutically acceptable salts. These are often described with a Markush structure or generic formula.
-
Method of synthesis: Steps, reagents, or conditions specific to preparing the compound.
-
Therapeutic use: Methods of treatment, e.g., inhibiting a particular enzyme, reducing symptoms, or treating a disease.
-
Dependent Claims:
These narrow the scope around specific embodiments, such as particular substituents, dosages, formulations, or methods of administration.
Scope and Limitations:
- The claims likely encompass specific chemical entities with defined substitutions at particular positions.
- They may extend to pharmaceutical compositions containing these compounds and their methods of use for targeted indications (e.g., cancer, autoimmune diseases).
- The patent possibly emphasizes pharmaceutical formulations with improved stability, bioavailability, or reduced side effects.
Claim Language Characteristics:
- Use of "comprising" suggests open-ended claims that include extra elements.
- Precise chemical language and stereochemical descriptors narrow enforcement to specific embodiments.
- Use claims aim to cover methods of treatment, a common strategy in pharmaceutical patents.
Claim Validity and Breadth:
- The scope balances granting broad protection over chemical entities or uses against the patentability standards of novelty and inventive step.
- The reissue may have broadened claims to include additional salts, stereoisomers, or different therapeutic indications.
