Too late (https://www.google.com/patents/WO2004095226A2?cl=en&dq=%22pa...). Dude beat you to it by several years.
It is sad this serious problem has been so poorly addressed for so long. If we are lucky in the next couple of years at least the most egregious attacks on business using a broken patent and legal system will be reduced, though even that may fail to be done :-(
Are they doing anything with this patent?
