Patent Overview and Context
The ’747 patent was granted on September 3, 2013, with inventors and assignees indicating a focus on a specific drug delivery system or a novel chemical compound. While the precise claims focus on particular compositions, methods, or formulations, understanding the patent’s scope requires an in-depth review of claim language, which delineates the boundaries of exclusivity.
This patent exists within a complex landscape marked by overlapping innovations in drug formulations, delivery methods, and therapeutic agents, with key players patenting combinations of known compounds, novel excipients, or unique administration protocols.
Claims Analysis: Scope and Purpose
The core of any patent's enforceability and commercial relevance lies in its claims, which define the proprietary rights. The ’747 patent comprises numerous claims, typically categorized as independent and dependent:
- Independent Claims: These outline broad inventions covering the key innovation, such as a specific drug formulation or delivery method.
- Dependent Claims: These narrow down the scope, adding particular features, such as specific excipients, dosage forms, or process steps.
Independent Claim Analysis
The primary independent claim (Claim 1) of the ’747 patent likely describes a composition or method involving:
- A pharmaceutical formulation comprising a specific active ingredient.
- The inclusion of particular excipients or carriers.
- A method of administration or manufacturing that enhances stability, bioavailability, or patient compliance.
For example, if Claim 1 defines a "Drug composition comprising a therapeutically effective amount of Drug X in combination with excipient Y, wherein the composition exhibits improved solubility," the scope encompasses any similar formulation meeting these criteria, regardless of the specific excipient source unless further limited.
The broadness of Claim 1 influences its strength: it can encompass multiple embodiments, thus providing extensive protection if upheld during infringement proceedings.
Dependent Claim Analysis
Dependent claims specify particular features—such as specific concentrations, formulations, or process parameters—that narrow the scope. For instance:
- Claim 2 might specify a particular dosage range.
- Claim 3 might define a specific excipient or stabilization technique.
- Claim 4 could detail specific packaging or administration protocols.
Such claims are instrumental in defending the patent's infringement and establishing specific market segments.
