Tim Lee has written a nice write up for recent legal progress in rolling back the software patent madness of recent years. It's good news for those of us who spend our time coding and don't want to get wrapped up in frivolous lawsuits designed to extort money.
Now a series of decisions from lower courts is starting to bring the ruling's practical consequences into focus. And the results have been ugly for fans of software patents. By my count there have been 11 court rulings on the patentability of software since the Supreme Court's decision — including six that were decided this month. Every single one of them has led to the patent being invalidated.
