I don't see how they could have gotten an order under the Patriot Act. The section that deals with this is section 215, which amended section 501 of FISA.
It specifically states that such an order can be made "provided that such investigation of a United States person is not conducted solely upon the basis of activities protected by the first amendment to the Constitution".
If they have been violated, then there are a number of members of Congress and the Senate who are falling down on their job - the Attorney General must inform the Permanent Select Committee on Intelligence of the House of Representatives and the Select Committee on Intelligence of the Senate. On top of this, every 6 months the Attorney General must also provide a report to the Committee on the Judiciary of the House of Representatives and the Senate which details the total number of applications made for orders approving requests for the production of tangible things and the total number of such orders either granted, modified, or denied.
I've read and documented the USA PATRIOT Act on Wikipedia incidentally. Took me two years to read and understand the thing. Possibly things after the Patriot Act changed FISA, I wasn't going to spend any more time on writing up about this subject. I'm an Australian citizen, after all.
I should note that I'm not thrilled about the fact that the U.S. government can read my communications. Not that I have anything to hide, nor am I of any interest to them, but hardly the point.
The two parts to read on Wikipedia, incidentally are:
