The client demanded a web application to analyze patent’s and identify the most important patents in a network. By utilizing the knowledge hidden in citation information, patent citation network introduces a new approach to search patent databases and to build and analyze technology landscapes.
The Patent Citation Network Research Tool references called as “Citations” to relevant prior art in the technology area of the invention. Citations are provided by the inventors as well as by the patent examiners. Citations are therefore easily accessible, ready-made compilations of the most important concepts in a technology area.
The citation network consists of Ego-centric Citation Network and Social Citation Network. An ego-centric citation network of a patent consists of a central patent (ego) and all patents that either cite or are cited by the central patent. The network includes citation links between all nodes in the network. A social citation network of a patent is a multi-level (or depth) citation network.
Depth 1 Social Citation Network of a patent includes all patents at a distance of 1 citation link from the central patent. The citation network also includes citation links between any of the patents. Depth 1 Network of a patent is the same as its ego-centric citation network.
Depth 2 Social Citation Network includes all patents at a distance of maximum of 2 citation links from the central patent. The citation network also includes citation links between any of the patents.
United States Patent and Trademark Office (USPTO): Contains only US Patents and citations to US Patents. Also, USPTO requires the numeric patent number and depth as input. It can take only US Patent numbers (granted) as input. The output citation network contains only US patents (granted as well as applications).
European Patent Office (ESPACENET): Contains patents and citations to patents from multiple countries including US patents. However, not all US patents are covered in the ESPACENET database. ESPACENET requires the complete patent number (including the country prefix and the kind code suffix) and depth as input. It can take patent numbers from multiple countries as input. The output citation network contains patents from multiple countries.

The patent citation research tool was built around PHP. Modules were developed in PHP such that they can be executed directly from the UI layer. These PHP files consisted of all the business logics used for respective modules like Save (Add/Update), Delete, Get Single Object,Get Multiple Objects for Listing and were designed to be capable of handling many more logics which were not related to the database.
In order to most effectively access the database in an object-oriented context, an interface translating the object logic to the relational logic was used to communicate with the relational databases in an object-oriented manner. An intermediary abstraction layer was created for accessing data from the database. Stored procedures were used only for complex retrieval of data from multiple tables and were entirely avoided with conditional syntax to ensure smooth performance of the website. The UI layer was kept free of any business logic with images, applications and data being called from their respective servers.
The site was equipped with a robust architecture to quickly analyze a patent’s citation network to identify the most important patents in that network. It enables the user to understand the technologies in vogue and gives quick and efficient results for patent’s citation network but also shows how strong your portfolio is. Extensive pre-development research was carried out to make the entire database compatible. Web usability guidelines were strictly followed during development and the interface was made easily navigable through judicious use of CSS and HTML controls. The site was developed and fully functional in a short span of time.
