everything going right for obj, page-8

I don't think you can presume that 3M are paying OBJ for the evaluation of their product. I they were OBJ would have to declare this to the market,

No they dont have to declare this to the market. OBJ made $800Kin revenues last half and I didn't see announcements that account for that $800K. As with other details, amounts are most likely being kept secret due to confidentiality agreements. One thing we know for certain, 3M have paid for previous evaluations, cant see why they wouldnt be paying this time around, in fact I'd be almost certain they are.
