So what does this patent mean?

From previous Greenshift filings we have this:

"While each of the competing extraction providers has copied our patent-pending extraction technologies, they have done it poorly; their average yield is about 25% of our proven yield. The competing installations that we have seen also increase the host ethanol facility's use of fossil fuel, thereby reducing the net value of the oil that they are able to extract. Conversely, we reduce the utility costs of our ethanol clients by about 10%."

"Issued patents can be expected to have significant negative consequences for unauthorized use of our technologies by third parties."
