The Owner column flags when a patent's current assignee of record is not the marketing institution (a "Third party" or "Assigned away" tag means you may not be able to license it from that university). The Expiry column reads how much exclusive patent term remains: an "Expiring soon" or "Expired" tag means little or no exclusivity is left, whatever the listing says.
