possibly, doesn't seem to be exactly like I remember but is quite possibly my memory fail. Although it's not clear in your comment where the market value comes from (e.g. is it essentially the government is the market maker? that seems like a bad idea as central authority is unlikely to understand and price everything correctly). What stops people from understating the patent value?

EDIT - I guess main point is - is the patent value declared by owner and does the value affect ability to litigate?
