- Gel Composition: The gel typically includes a mixture of polymers, solvents, and other excipients that facilitate the release of nitric oxide.
- Therapeutic Applications: The patent outlines various uses of the gel, such as treating acne, wounds, and other skin conditions[4].
Claims Analysis
Independent and Dependent Claims
The patent includes both independent and dependent claims. Independent claims define the broad scope of the invention, while dependent claims narrow down the scope by adding specific limitations.
Independent Claims
- Claim 1 typically defines the broadest scope of the invention, such as the composition of the topical gel and its method of use.
- For example, Claim 1 might state: "A topical gel composition comprising a nitric oxide-releasing compound, a polymer, and a solvent, wherein the composition is adapted to release nitric oxide upon application to the skin"[4].
Dependent Claims
- Dependent claims build upon the independent claims by adding specific details or limitations.
- For instance, a dependent claim might specify the type of polymer used, the concentration of the nitric oxide-releasing compound, or the method of preparing the gel[4].
Claim Scope and Concepts
To understand the full scope of the patent, it is essential to analyze the claims in conjunction with the broader scope concepts. This involves categorizing the claims not just by their individual elements but also by the overarching concepts they represent. For example:
- Scope Concepts: These could include the type of nitric oxide-releasing compound, the specific polymers used, and the therapeutic applications of the gel.
- Claim Coverage Matrix: Using tools like a Claim Coverage Matrix, one can identify which patents and claims are actively protecting the intellectual property and where gaps or opportunities exist[5].
Patent Landscape
Global Dossier and International Search
To fully understand the patent landscape, it is crucial to look beyond the U.S. patent system. Tools like the Global Dossier and international patent databases (such as those provided by the European Patent Office, Japan Patent Office, and World Intellectual Property Organization) can help identify related applications and prior art globally[1].
Common Citation Document (CCD)
The Common Citation Document (CCD) application consolidates prior art citations from multiple patent offices, providing a single point of access to citation data. This helps in visualizing the search results for the same invention produced by several offices on a single page[1].
Patent Analytics
Patent analytics tools can help in tracking patents by claims and scope concepts, providing a clear picture of the patent landscape. These tools can categorize patents by claims and scope concepts, making it easier to identify gaps in coverage and future design opportunities[5].
