Very interesting. Thanks for posting. Didn't know about all the B&N litigation. In some sense it's a big landmark against software patents. Huge amount of blowback, and now it's much harder to get a software patent. That's a good thing.

The interesting thing is that the biggest changes to how we handle software patents came from the courts, not Congress. I suspect that eBay v. Mercexchange had a bigger impact on SCOTUS than Amazon did, but there was a ton of law review activity around the '411 patent. I must imagine this was a factor in judicial decisions around 101 eligibility.
