Advent Product Development and Triad Resources Inc PMB Said they would help me promote, market, sale and patent my invention. Pawley's Island SC

i have read all the reports that was listed on this site for the advent product development and triad resources inc pmb and was wondering if there was any type of class action law suit? my family and i was a victim of this company also back starting in 2004 which we gave them almost $30,000 and was just wondering if there is anything that i can do now. i still have all the paper work that was sent to me by this company because i was waiting to see if anything came about. if someone can just let me know if it's too late to do anything or if there is something i can do now.
