You can find patent family information (see also Patent Family in Glossary,) including the family members’ patent numbers, titles, legal status, publication/ issue dates, application date, and their related post-grant proceeding cases.
The Legal Status column reflects the most recent status of each patent. Based on their prosecution and maintenance fee payment status in the PTO databases or the INPADOC data, the Legal Status of the US, CN, EP, JP, KR, TW, WO among 30+ PTOs include Pending (pending application,) Active (granted and maintained,) and Inactive (abandoned or lapsed due to no payment, or expired). For the rest of countries, the legal status may only reflect on either Issued or Published.
Back to the Family Prior Art tab. When clicking on the number in the box of “Backward Citation: Patent”, you can further go to the backward citation page.
On the backward citation page, you can find prior art in the family citations of the patent at issue, especially citations of its family counterparts that are foreign patent applications. The "References" column lists the family members citing the prior art reference, and:
If the family member is abandoned during application, it will be marked with "ABAN";
If the prior art reference was considered as 35 U.S.C § 102/103 prior art in the prosecution, re-Exam, IPR/CBM review or Post-grant review of the family member, it will be marked with "*/E/I/P", "102/103". (For example, "*102" for § 102 prior art in prosecution history.)
To quickly search for the prior art, enter “*102” or “*103” or even “ABAN” in the search box.
In addition to List View, Quality Insights offers Grid View with the first figure and abstract among other important patent information to facilitate a quick evaluation of relevant patents.
