Our patent application was approved back on Aug 12. I didn't find out until today. Dynamic legal database providing historical and current versions of bodies of law It's patent number 7412463. Laws change on a daily basis, but law books are only published periodically, typically annually. If you are charged with a violation because of actions that occured on a particular date, your lawyer would be interested to know what the law was on that date along with knowing what other relevant laws were. We invented a way to database the laws so that that you can view the entire legal code as it would have appeared had it been published on that day.
