I was once hired to find a way around the Danley patents and yes the two appear to be the same, although there is a subtle difference. The second seems to be a generalized version of the first. The first mentions the need for specific locations along the device and the second relieves this and is more general as to placements.

My recommendation was that the second was so general that it would be very difficult to impossible to get around, although this vast generality would also IMO make it invalid.

The client was not interested in contesting the patent, so it ended there.

Thus, I agree that the patent issue would be a big problem for a mass produced device. Who is going to take on that issue for the minimal interest (and profits) that would ensue?

Bill, you may even be infringing by making the 3D models available. This is called "inducing to infringe".

It seems even an invalid patent can protect an invention

That's why so many people do it.

Oh the joys of living in a litigious society. Who needs to worry about being right when you have enough money to bury the other person in law suits.

Tom Danley himself has given Bill the go ahead before to share his designs so one could only hope they don't feel the need to do any different this time.
