Over the last few months, since the Supreme Court‘s ruling in Alice v. CLS Bank, we‘ve been noting the good news that the courts seem to be interpreting the ruling to invalidate a ton of software patents. Even some trolls have decided to just give up after seeing how the Alice ruling is being interpreted.

A new analytical study of patents held by big tech companies, done by ktMINE, suggests that more than half of Google and Microsoft‘s patents are invalid under Alice.
