Bayes theorem challenged in court | The Guardian

Bayes' theorem.

A formula for justice

Bayes' theorem is a mathematical equation used in court cases to analyse statistical evidence. But a judge has ruled it can no longer be used. Will it result in more miscarriages of justice?

Interesting note and questions on mathematical patents

I was reading about the "Automated Reduced Error Predictive Analytics" patent secured by Rice Analytics (see below) and my first question is:

How can you successfully sue competitors about using a mathematical technology?
