little digging from this post. maybe something. on july 27, 2020 mateon spun edgepoint ai into a subsidiary of mateon. probably leaving king and edgepoint to go public???? to be announced by mateon. digging further. some of these companies have trouble raising 2 million dollars. enter ptsc, with a small piggy bank to fund a merger. probably expect a reverse split. but better bankruptcy  would be final. maybe nothing who knows. again timing
