I was searching patents.google, and I encountered this patent:

enter image description here

I found this ambiguous, so I just wanted to seek clarification: Does this mean that the patent has indeed expired (fee related), or that it was expired (fee related), and "revived" with an adjusted expiration of 2024?

I would greatly appreciate it if people would please clarify this.

  • It would make things easier if would link to the patent page.

  • Just so you know, it’s possible to make up for a missed fee payment. I assume that is what happened here.

  • @EricShain patents.google.com/patent/US7123363B2/en?oq=7%2c123%2c363 I'm aware of this. But my point is that it says that the "status" is "Expired - Fee Related", so it's not clear to me whether or not the fee was paid and the patent revived. Apr 24, 2020 at 2:15
  • Google patents tries to be helpful, but as George White points out, you really need to consult the Public PAIR site to get authoritative information.

To get to the bottom of almost any issue with a U.S. patent go to Public PAIR. The site is fussy about the format of the application number or publication number you enter. I see the expiration due to fee nonpayment but I do not see any petition to revive so I would guess that the info panel at google patents is garbled.

  • Is the date this patent was actually expired 11-14-2014? I can't find an explanation for the "Expire Patent" transaction on PAIRS.
