I don't know what their logic is for letting anything expire -- that is a good question for the CEO. Some here claim he answers emails. Others claim you can leave a phone message on the corporate phone number.
All I know is, the only existing patent expires on June 3 2014, and currently there is only one outstanding active patent application. It's in the USA. That application was initially submitted in 2009, received a final rejection on 08/13/2012, was resubmitted with a Request for Continued Examination on 02/15/2013, had the IDS filed on 02/28/2013, and nothing has happened since.
Part of the UNI agreement stated that UNI would pursue the patent applications. After that agreement was signed, the EPO patent became "withdrawn" because the renewal fee wasn't paid. Who was responsible for paying that fee? Another good question for the CEO.
CIT still has an active patent, by the way. That patent was issued in 2004, I believe.
