What Is Legal Search and How Do I Use It?

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.

You can learn more about our Advanced Search here: What Are The Advanced Search Query Options?

 

Litigation

The first option is Litigation. We currently have litigation data for CN/TW/CA/US/JP/FR/GB/AU/ES patents.

  • Decision - PatSnap will search for patents where the final decision of the case contains what was inputted.

  • Legal Grounds - PatSnap will search for the legal grounds that had been cited in a case. 
  • Decision Date - PatSnap will search for patents where the date that a decision regarding re-examination/invalidation has been made for the dates inputted.

If the left-hand option is left blank then the search will be up to the date inputted on the right and if the right-hand option is left blank then the search will be from the date inputted on the left.

 

Pledge

The fifth and final option that you can search using "Legal Search" is Pledge. We currently only have pledge data for CN/US patents.
