The Greenshift lawsuits have absolutely nothing to do with "the government".
Greenshift's subsidiary GS Cleantech is suing a bunch of corn-ethanol producers to force them to pay royalties over Cleantech's patent.
The lawsuit is going awry, Cleantech's patent has been found to be invalid, and, furthermore, it has now been legally established that Cleantech has hidden key information from the Patent Office in its patent application.
That means it will be difficult for Greenshift to enforce its patent until its appeals are adjudged. That is likely to take years, and cost between $1M and $2M of legal fees per year, while GS revenues stall and dwindle.
Once again, those are intellectual property lawsuits against private corporations, nothing to do with "the govt".
