We have discussed the liens a few times here, part of the contract to take us on a contingency basis, as a form of colateral. It's in effect what is done by sub contractors and suppliers of product in the construction field, to file a preliminary lien notice, and give monthly releases when progress payments are made. It also assures DM in the event of a buyout, they get their 15% of the value of the patents, then release the liens to the buyer. In construction, if an owner/lender defaults, the GC, subs and suppliers file a mechanics lien on the property/building, making them a party to an Escrow when the property/building is sold.

It's just common sense smart business practice on DM's part.

I sure hope DM kicks it in gear and does not wait for the bogged down USPTO to finish the re-exams.
