The search results are about "PGR" stock, which is The Progressive Corporation, an insurance company. These are not relevant to US Patent 12427372.

Since there are no PTAB proceedings, there is no estoppel landscape under 35 U.S.C. § 315(e)(2) for any potential petitioner. All prior-art grounds remain available for challenge, should a party decide to file an IPR or PGR.
The absence of PTAB activity suggests that the patent has not yet been subject to the scrutiny that often accompanies asserted patents, particularly those involved in litigation.
