So - it seems to me GT is now filing further patents apart from POET / OPEL. Could well be that INTOP is a frame company holding the new patents. Who are the owners of INTOP? Has someone in the US access to the register of companies?

No idea which contracts POET has in place with GT or UCONN. Where is GT doing his work, performing his trials? Is there still a consultancy contract in place? Questions to be directed to the IR of POET, but I fear they will not answer...
