Yes, makes sense to raise cash to pay for the legal team, consultants, court fees, Patent office fees, insurance, etc. (Re.: 10Q). Pay employees and a few others cash plus company stock. They have avoided borrowing and debt so far.
All likely to change for better by next qtr when the cash settlement (MG case) from AMZN shows up in their books and the trial decisions by AMZN (RBR case), TMUS and VZ before the year end.
