Verdict

Operating-company assertion
The patent remains assigned to Six Trees Capital LLC, the original assignee and an operating company that develops and markets the MaxMyInterest financial optimization service, which embodies the claimed invention. The absence of post-issuance assignment records in the USPTO Assignment Center, combined with evidence of litigation, indicates that Six Trees Capital LLC is actively asserting its patent.
