You forgot that besides the patents sell-off, they'll sell just anything the company owns to another company owned by them, just to lease everything back so the company can accumulate dept. In the same trend work gets sent to sub-contractors owned by them, and consultants get hired to make sure the value of the company rises because they invest in getting better at whatever.
Also, If most off these things don't happen at your company, then all value is allready extracted and only the depts will pile up until bankruptcy.
