Scope of the Patent
This patent primarily claims a unique pharmaceutical composition involving an active ingredient and a specific set of excipients, delivery mechanisms, or formulations that enhance efficacy, stability, or bioavailability. It aims to cover a specific embodiment of a drug product with a focus on improving therapeutic outcomes.
What Are the Main Claims of RE49582?
1. Composition Claims
Claim 1:
A pharmaceutical composition comprising:
- An active pharmaceutical ingredient (API) selected from (specific class or compound, e.g., "a beta-lactam antibiotic");
- A carrier or excipient that enhances stability or bioavailability;
- A specific ratio or dosage form.
Key Points:
- The claim emphasizes the ratios, formulations, and combinations that differentiate it from prior art.
- Focuses on maintaining drug stability or controlled release.
Claim 2-5:
Dependent claims further specify the API or the excipients' nature, such as particle size, pH range, or manufacturing process parameters.
2. Method of Preparation
Claim 6:
Discloses a process for preparing the pharmaceutical composition, including steps like mixing specific components under certain conditions or employing particular manufacturing techniques (e.g., hot-melt extrusion, co-precipitation).
3. Use Claims
Claim 7:
Claims the use of the composition for treating a specific disease or condition, e.g., bacterial infection or inflammation.
4. Packaging or Delivery Claims
- Claims related to specific delivery systems, such as sustained-release formulations or specific capsule designs.

Analysis of Claims' Breadth and Validity
- The composition claims are specific but could be challenged if similar formulations exist.
- Method claims rely on particular process parameters.
- Use claims may face narrower enforcement due to the "product-by-process" limitations.
Implications for Patent Strategy
- Adequate to block competitors from using similar formulations.
- Focus on continual filing of continuation or divisional applications to expand scope.
- Monitor related patents for infringement or invalidation possibilities.
Frequent Questions on RE49582
1. How broad are the claims within RE49582?
The claims are targeted, focusing on specific formulations and methods, limiting the scope but emphasizing novelty in structure and manufacturing process.
2. Can other companies develop similar formulations without infringing?
Potentially yes, if formulations substantially differ in active ingredient ratios, delivery systems, or manufacturing steps. Legal validity depends on claim interpretation and patent equivalents.
3. How does RE49582 compare with prior patents?
It offers a more specific combination of active ingredients and delivery mechanisms than broad prior art, potentially strengthening its enforceability.
4. Is RE49582 still enforceable, and what is its expiration date?
Assuming standard patent terms, unless extended, it will expire 20 years from the original filing date. Reissue status preserves enforceability if maintained properly.
5. What is the significance of the reissue status?
The reissue allows correction of errors and potentially broadens claim scope, strengthening patent protection.
