Further advancements in Patent discoverability and strategic insights

We know from your feedback that patent discoverability for competitive intelligence analysis is important, particularly if you’re interested in patent ownership and how it changes over time. To meet this end, we have joined forces with PatentSight GmbH to integrate the latest information on patent ownership and patent assignee data. This integration is a testament to our commitment towards improving the user experience in the patent discoverability space. 

New patent ownership information

Now you will be able to distinguish between “Current Patent Assignee” and “Original Patent Assignee” for a patent document. The orginal assignee is defined as the assignee at the moment of first patent submission. Changes in assignee data will allow you to discover if IP transfer has occurred between organizations, providing richer inisghts into your competitive landscape.

This new information will be visible in the bibliographic record for a patent and you will be able to use it to narrow down searches with query options and filters.

Better visibility of patent bibliographic data in document results pages

  • For a given patent document, the “Front Page Info” is now changed to “Bibliographic Info” (A). We understood that the “Front Page info” did not resonate with you very well and you might be missing on some important patent information.
  • The “Bibliographic Info” contains information about both “Current Patent Assignee” and “Original Patent Assignee” (B).
  • The assignee information is clearly marked as “Current Patent Assignee” to avoid any confusion regarding the displayed information (C).
  • In addition, the “Bibliographic Info” also contains other relevant information on patents such patent numbers, IPC classes, Kind Code, Inventors, etc (D).

New filter options

To ensure you can effectively filter the “Inventor” and “Current Patent Assignee” information, the data has been updated and cleaned. This means that you can now expect to find the required data more easily and can have a better experience with the filters.

  • The “Authors” filter has been updated to “Authors/Inventors” (E). This change will accommodate both journals and patents under the same filter, making your search experience easier.
  • The “Patent Assignee” filter has been updated to “Current Patent Assignee” (F) for a consistent layout across Reaxys. As the name suggests, this filter will contain only the current patent assignee information.

New advanced search options

In addition to the filters, you can also set up advanced searches for both new fields:

  • To search by “Current Patent Assignee” you can use the quick link on the top (G) for a shortcut.
  • You can use querilets for “Current Patent Assignee” (H) or “Original Patent Assignee” (I) for specifc searches on the Reaxys Query Builder. This new addition will help you differentiate between the original and the current patent assignees.

What is next?

We continue to work towards further improvements in the discoverability of Patent Ownership/Assignee information via Quick Search and Query Builder
