A quick read through the news release seems to confirm that they only sold the part of OPEL Solar that were used in conjunction with the use of it's single axis solar power tracker business (the "Business"). So it seems we still have the IP that relates to the dual axis trackers and of course the POET IP regarding solar applications since the news release states that any asset that is not used in, or related to, the "Business" is not included in the sale. We were using Boeing solar cells at the time.

"Toronto, ON and Storrs, CT, December 14, 2012 - OPEL Technologies Inc. (TSX-V: OPL and OTCQX: OPELF) (“OPEL” or “the Company”) today announced that it and its affiliate OPEL Solar, Inc. (“Solar”) have entered into a definitive agreement (the “Agreement”) with Northern States Metals through its subsidiary, Tracker Acquisition, Inc.(the “Purchaser”) to sell the non-cash assets of Solar used in connection with the operation of Solar's single axis solar power tracker business (the “Business”). The purchased assets do not include any asset of Solar that is not used in, or does not otherwise relate to, the Business and certain other non-core assets."

This is just my opinion, but it should be no problem to confirm if one thought it was important right now.
