Legal search is used to assist PatSnap users to create queries using legal parameters. The results generated by a Legal Search will help you learn more about particularly litigious companies, where licensing deals or re-assignments have taken place and where a particular company's patent(s) have been made invalid or have required re-examination.
Legal Search has five different categories to select from. Litigation, re-examination/invalidation, licensing, assignment, and pledge. All of the categories have two sections of search fields: General fields and Patent fields.
Each of the different jurisdictions might have slightly different search options in terms of the "General Fields", which is due to the differences between their legal systems but they all have the same options in terms of the "Patent Fields", which use the same format as the Advanced Search.

Litigation View
In the Litigation Search section, it is also possible to select the "Litigation View". Located at the top of the text box that displays a preview of your query.
When you select Litigation View to perform your search, the query building process is exactly the same as any other search type in PatSnap, the difference is that after clicking on Search, the results page will list litigation cases instead of patents. Each case will display its title, its case No., the case's plaintiff and defendant, the verdict date, the date the case was closed, and the patent(s) involved in the case.
The Refining sidebar on the left-hand side of the screen will also display different refining options.
Normally, when you click on one of the results that were returned after doing a standard patent search, a new tab would open displaying the "Patent View", where you can inspect various sections containing relevant patent data like Abstract/Claims/Description, images, the patent's pdf, etc. When you select a result while using the "Litigation View", a new tab will be opened, but it will only display information relevant to the case. Similarly, the list of results that appear on the sidebar on the right-hand side of the screen will be made up of cases.
