Seems as though WILN has dropped to less than half

Seems as though WILN has dropped to less than half of where it was 3 months ago. Just happened across this stock while doing my DD and considered buying in until I realized a steady decline in the pps. Can anyone tell me why this has only dropped steadily being their lawsuit has been taken care of and they have a patent license agreement with Crane? would appreciate anyone who has been following WILN over the course of this year and knows their history. Thank you-Rick
