The current assignee of record is University of Tokyo NUC. Google Patents reports its legal status as \u201cActive\u201d (an automated indicator, not a legal determination). Its expected expiration is 2042-06-21. Note: the patent's assignee of record is now University of Tokyo NUC, not Stanford University (OTL); it appears to have been assigned away, so licensing rights should be confirmed with the current owner.",
