TT Consultants has special teams of patent crunching engineers working full time on patent validity searches; these engineers are skilled in the art of patent invalidation. Searches are conducted on paid as well as non paid databases. A concise report containing the details of the search conducted, databases searched, key strings used, search strategies adapted and relevant parts of the citations is presented to the client.

We adapt the following search strategies for conducting patent validity searches (patent and non patent literature search):-

Keyword based search: The keyword based search is conducted as under:-

• Key Features of the invention are identified based on the novel aspect of the invention.
• Relevant key words and their variations are determined based on the key features and the technology domain.
• Different key strings with variable scope (broad to narrow) are formed and a search is conducted on different databases.
• Search results obtained from the search strings are analyzed and relevant patent publications are identified.
• Relevant Classes are identified and search is conducted in the relevant classes.

Citation Analysis: A citation based analysis is conducted for all the relevant publications found during the search.

Assignee/Author based search: An assignee based analysis would be conducted for all the relevant publications found during the search.

Inventor based search: An inventor based analysis would be done for all the relevant publications found during the search.

The Search reports may thereafter be examined and legally correlated by the concerned attorney in the context of the litigation.
