The last PR that I am aware of where TPL was mentioned as a co-owner was on 2-16-11 when there was a PR about the 890 and 749
The last license announcement where TPL was mentioned as a co-owner was on 5-23-11 when Stryker was signed.
It would appear that since the settlement, PTSC is not required to mention TPL as a co-owner. Perhaps the BoD will address this at the SHAM
