I wonder if TZ has maintained its patent portfolio, which cost multi-millions of dollars to develop - or without Dickory driving it forward, has allowed the applications in progress to fall away and/or let granted patents lapse?

Remember all of the aerospace, automotive, defence, medical, industrial, transportation applications? The interesting high-tech stuff?
