What Is Legal Search and How Do I Use It?

Legal search is used to be able to search using specific legal parameters. Where the different categories you can search within are litigation, licensing, assignment, pledge and re-examination/invalidation. This is useful information to have because it will enable you to find out 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.

Litigation

The first option that you can search using is litigation. 

Each of the different jurisdictions has slightly different search options in terms of litigation which is due to the differences between their legal systems but they all have the same options in terms of the field search (which is the case for the other categories of legal search as well) as well as being able to search including English machine translations, as seen below, where you can find more information about these here: (What Are The Advanced Search Query Options?)

 

China

 This is an explanation of each of these different options:

  • Case Number - PatSnap will search within case numbers for what was inputted.
  • Court Name - PatSnap will search within court names for what was inputted.
  • Chief Judge - PatSnap will search within chief judge names for what was inputted.
  • Judge - PatSnap will search within judge names for what was inputted.

  • Filing Year - PatSnap will search for patents that had a case filed against them in this year.
  • Verdict Date - PatSnap will search for patents which had a verdict in a case against them between 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.
  • Trial Grade - PatSnap will allow you to search for patents that have been given a specific trial level (first instance/second instance/retrial)
  • Case Property - PatSnap will allow you to search for patents that have been given a specific case type (civil/administrative/execution/intellectual property)
  • Case Region - PatSnap will allow you to search for patents that have had cases filed against them in a specific Chinese province.
  • Title - PatSnap will search within case titles for what was inputted.
  • Fulltext - PatSnap will search within the full text of the case file for what was inputted.

  • Status - PatSnap will allow you to search for patents by the specific status that the case currently has.
  • Date of Filed - PatSnap will search for patents where the case against them is filed between the dates inputted.

  • Effective Date - PatSnap will search for patents where the date that a licensing deal for the patent has taken effect is between the dates inputted.

Pledge

The fourth option that you can search using is pledge. We currently only have pledge data for CN/US patents.

Each of these jurisdictions has slightly different search options in terms of pledge which is due to the differences between their legal systems.

China

The USA

All of these options have already been covered when discussing Chinese pledge search options, as seen above.

Re-examination/Invalidation

The fifth and final option that you can search using is re-examination/invalidation. We currently have re-examination/invalidation data for CN/US patents.

Each of these jurisdictions has slightly different search options in terms of re-examination/invalidation which is due to the differences between their legal systems.

China

This is an explanation of each of these different options:

  • Decision Number - PatSnap will search within decision numbers for what was inputted.
  • Type - PatSnap will allow you to search for patents by the type of re-examination/invalidation that has taken place or is currently taking place for the patent (re-examination/invalidation/oral hearing).
  • Petitioner - PatSnap will search within petitioner names for what was inputted.
  • 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.
  • Decision Points - PatSnap will search for patents where the main points/basis for the decision in the case contain what was inputted.   
  • Decision - PatSnap will search for patents where the final decision of the case contains what was inputted.
  • Full Decision - This may also be considered to be "full text" since this includes the case summary, the reason/the basis for the decision in the case, therefore, in this case, PatSnap will search for patents where the full text for the case contains what was inputted.

USA

    

 This is an explanation of each of these different options:

  • Decision Number - Same as for China.
  • Type - Similar as for China but different options are available here (inter partes review/covered business method review/post-grant review)
