The VC patent application cannot affect our patent or our patented process because their priority date is 24 Feb 2017, while ours is 2010 or 2011. The PCT application has an International Search Report with two X category documents which the patent office considers invalidate many of the 143 claims of the VC patent application. They have mis-characterized our patent US9702025, claim 1 of which which uses "acid leach", not limited to HCl, nor is the acid percent limitation included in claim 1. Although I have not studied their process, it is possible VC may encounter an infringement problem with our patent.
