Inter Partes Review (IPR) Case:

The Google Patents page for US10552490 indicates: "PTAB case IPR2025-00254 filed (Pending - Instituted)". While Unified Patents Portal lists IPR2025-01254 associated with patent 12268475 and IPRs for other patents, a direct search for "IPR2025-00254" on Unified Patents did not return specific details for US10552490, but rather for patent 12268475. However, given the direct mention on the patent page itself, it is reasonable to conclude that IPR2025-00254 is related to US10552490, and its status is "Pending - Instituted." Further details like petitioner and owner are not available in the immediate search results, but Unified Patents often represents petitioners in IPRs.
