Understanding the Scope and Claims of United States Patent 6,080,756
Introduction
United States Patent 6,080,756, titled "Polymorphs of the prodrug 6-N-(L-ALA-L-ALA)-trovafloxacin," is a patent that delves into the realm of pharmaceutical compositions and methods related to a specific prodrug. Here, we will analyze the scope, claims, and the broader patent landscape surrounding this invention.
Background of the Invention
The patent focuses on polymorphs of the prodrug 6-N-(L-ALA-L-ALA)-trovafloxacin, which is used in the treatment of bacterial infections. The invention includes methods of using and pharmaceutical compositions comprising these polymorphs[4].
Scope of the Invention
The scope of the invention is defined by the patent claims, which are the legal definition of the inventor's protectable invention. Here, the claims encompass various aspects of the polymorphs, including their composition, methods of preparation, and methods of use.
Claims Analysis
Independent Claims
Independent claims in a patent are standalone claims that define the invention without referencing other claims. For US Patent 6,080,756, the independent claims would typically include:
- Claims for the composition of matter, such as the specific polymorphs of the prodrug.
- Claims for methods of making these polymorphs.
- Claims for methods of using these polymorphs in pharmaceutical treatments.
For example, an independent claim might read:
"A pharmaceutical composition comprising a polymorph of 6-N-(L-ALA-L-ALA)-trovafloxacin, characterized by a specific X-ray diffraction pattern."
Dependent Claims
Dependent claims further limit the scope of the independent claims by adding additional elements or steps. These claims incorporate by reference all the limitations of the claim from which they depend. For instance:
"The pharmaceutical composition of claim 1, wherein the polymorph is used for the treatment of bacterial infections."
Patent Claims Structure
Patent claims must be written in a specific format. Each claim must start with a capital letter and end with a period. The claims must be presented on a separate sheet following the detailed description of the invention. Independent claims are self-contained, while dependent claims refer back to and further limit another claim[2].
Patent Landscape Analysis
