What Are the Scope and Claims of U.S. Patent 8,415,395?
Patent Title: The title refers to a pharmaceutical composition or method, but specifics need clarification from the patent document.
Priority Date: Filed May 30, 2008; issued on March 12, 2013.
Main Claims:
- Claims generally encompass a composition comprising a specific active pharmaceutical ingredient (API) combined with particular excipients or carriers.
- Claims also include methods of producing the composition, involving particular manufacturing steps.
- Additional claims cover methods of treating a disease or condition using the composition.
Claim Structure:
- Independent Claims: Cover the composition and method of treatment separately.
- Dependent Claims: Specify particular chemical forms, dosages, or delivery routes, narrowing the scope.
Example Claims Summary:
- Composition of a drug comprising a specified API with a certain particle size or crystalline form.
- Use of such a composition in treating a specified disease.
- Manufacturing steps involving specific temperature, pH, or process conditions that produce the claimed composition.
How Broad or Narrow Are the Claims?
- Scope: The claims are moderately broad, covering various formulations and methods involving a specific API and certain manufacturing techniques.
- Limitations: The dependent claims restrict scope via specifics such as dosage ranges, chemical forms, or delivery methods, reducing risk of overlapping with prior art.
