Claims Analysis
The claims section of the patent is crucial as it defines the legal boundaries of the invention.
Independent Claims
Independent claims are the broadest claims in a patent and define the overall scope of the invention. For US9815835B2, these claims typically include the general structure of the compounds and their use in treating viral infections.
Dependent Claims
Dependent claims narrow down the scope by adding specific limitations to the independent claims. These might include specific substituent groups, dosages, or methods of administration.
Claim Coverage and Scope Concepts
To understand the full coverage of the patent, it is helpful to use tools like a Claim Coverage Matrix and scope concepts.
- Claim Coverage Matrix: This tool helps in identifying which patents and claims are actively protecting the intellectual property. It categorizes claims by their scope concepts, making it easier to filter and analyze large numbers of patent claims[3].
- Scope Concepts: These are overarching categories that link claims on similar patents. For US9815835B2, scope concepts might include the type of substituent groups, the specific antiviral activities, and the methods of use.
Patent Landscape
Understanding the broader patent landscape is essential for assessing the value and potential of the patent.
Related Patents
The patent landscape includes other patents related to antiviral compounds, particularly those targeting the influenza virus. Tools like the Global Dossier and the Common Citation Document (CCD) can help in identifying related applications and prior art cited by various patent offices[1].
Competitors and Market
Analyzing the patent landscape also involves identifying competitors who may hold similar patents. This can be done through patent analytics services that track patents by claims and scope concepts, helping to identify gaps or opportunities in the market[3].
International Considerations
Since intellectual property protection is not limited to the United States, it is important to consider international patent filings and protections.
- International Patent Offices: Databases such as those provided by the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO) can be used to search for similar patents filed in other countries[1].
Practical Applications and Future Directions
The practical applications of the patent include the development of new antiviral drugs targeting the influenza virus. Future directions might involve further research into the efficacy and safety of these compounds, as well as exploring other potential uses.
