I don't know about ya'll, but when I read through the patent rehash and amendments with the USPO and SGLB, it surely looks to me like SGLB will be getting a much better patent. The amendments seem to be very specific. It looks to me like SGLB is aiming for a lock on the patent rights for closed loop. It looks to me as though the only way around the patent is to develop a whole new way of doing IPQA. I mean how do you get around a statement that says sensors follow a path, monitor the melt-pool and provide function to make changes to the printer in such a manner as to alter the melt-pool? The sweeping amendments seem to be so encompassing that they are clearing out whole groups of USPO examiner exceptions/issues at one fell swoop. The examiner themselves even states that it looks good to go for issuance.
I think this will be a very big deal for SGLB.

All the best,
