Jeff, as the resident expert on patents, what is your opinion of the substance of the protection now afforded Sigma by the patents that have been issued to them?
Another patent to be issued soon. Application 16/434,577 (20190323903) was just recently made public and has already been allowed. It is titled 'OPTICAL MANUFACTURING PROCESS SENSING AND STATUS INDICATION SYSTEM' and is related to patent 10,317,294 which was issued 11-Jun-2019. Not sure how the two relate but they jumped on getting the 2nd one applied for and expedited.
