This may be a bit of old news at this point, but its still great news. Apple can now offer a defense to those developers being attacked by Lodsys. Hopefully they can defeat them, and then Lodsys will be out of business.
A sad note to come out of this is that some developers caved and started paying Lodsys. I understand the logic (saving money), but its only a short term gain. If they fought and lost, they would pay regardless. But by paying, they only funding Lodsys to go after developers like me, and that hurts the whole industry. And they also set a precedence for other patent trolls to come after small developers. Sure, its only 1% now, but when there are 50 companies asking 1% because nobody fault, then that’s a huge problem.
