Microsoft recently joined the Linux Foundation while still asserting its patents against the rest of the membership. As I found that odd, I tweeted some casually-calculated statistics about Microsoft’s patent revenues that seemed to me to simply be the aggregation of common knowledge. But maybe not – at least two respondents asked me to substantiate the figures. Having struck a nerve, this post is by way of explanation.
I, too, find it odd that Microsoft is now a ‘higher’ member of the Linux Foundation than, say, Red Hat, yet it still asserts its patents against various companies using Linux. It just doesn’t sit right.
