Microsoft hasn't exactly been the best friend to FOSS, but it's hard to feel good about the company's $290 million loss to i4i. The company lost its appeal in front of the Supreme Court, which has affirmed that issued patents are presumed valid. So much for common sense.
Why is this bad news for FOSS? It's not because Microsoft has to pay a stiff fine — the software giant may not have the deepest pockets of all software companies these days, but it's not going to suffer unduly here.
