Analyzing the Claims of Patent 5,855,906
To analyze the claims of Patent 5,855,906, you would typically follow these steps:
Identify Independent and Dependent Claims
Independent claims stand alone and define the invention without reference to other claims. Dependent claims, on the other hand, refer back to and further limit the independent claims[3].
Determine Claim Scope
Each claim should be examined to understand its scope. This involves identifying the key elements of the claim and how they are defined.
Evaluate Claim Language
The language used in the claims is critical. Terms such as "comprising," "consisting of," and "including" have specific legal meanings that affect the scope of the claim.
Patent Landscape Analysis
Understanding the broader patent landscape is essential for assessing the novelty and non-obviousness of an invention.
Prior Art Search
Conduct a thorough search of prior art using resources such as the USPTO's Patent Public Search, Global Dossier, and international patent databases like those provided by the European Patent Office (EPO) and the World Intellectual Property Organization (WIPO)[1][4].
Classification and Citation Data
Use tools like the Cooperative Patent Classification (CPC) database and the Common Citation Document (CCD) to identify related patents and citations. This helps in understanding how the patent fits into the existing technological landscape[1][4].
Office Actions and Patent Family
Review office actions and the patent family through services like Global Dossier to see how the patent has been treated by different patent offices and any challenges it may have faced[1].
Tools and Resources for Patent Analysis
