Any IP lawyers in the house?
Any thoughts on this. It seems pretty obvious as a development once you get into it and there doesn't seem to be much difference between the new patent and the expired patent. Layer adhesion is the big Achilles heel of 3D printing after all.

Not an IP lawyer, (those people are EXPENSIVE), It's perhaps less about the idea than it is about the process to get there. And yes the patent office does make mistakes at times. It's just expensive and hard to correct those mistakes because it generally takes a judge to do so. And I'm willing to bet this patent is valid in the EU also due reciprocity agreements and trade deals. It would take an EU judge to invalidate the patent, which would cost as much as doing so in the US.
One thing that I have learned over the years is that no patent is actually really valid until a judge bangs a gavel and says yea or nay to the patent, (I've held a couple). Until then, it pretty much just a piece of ass-wipe paper you can wavy around and hopefully scare off others that don't have the money or want to spend the money to challenge the patent.
