Some things were made permanent under subsequent laws (or at least extended). For example, financial reporting for people depositing "large" amounts of cash. I think it started out at $10k under the patriot act. Now I think it's $5k. That is a good bit of cash, but it could easily be made selling a used car or something.
90% of the Patriot Act was permanent law and is law today. A few of the most objectionable parts had "sunset" provisions in them and those (after several rounds of modifications and numerous extensions) are what has, finally, been allowed to expire. Most of the provisions of the Patriot Act are in effect today and will be until a future Congress changes them.
