Jeff and All,


Two things I don't understand. Both may relate to my limited understanding of patents.

1. The published patents, Sigma's and GE's - would they be identical, and the Patent office publish both, and thus the sole distinction may be the filing date? Or, would there have to have been, or likely have been some difference in content or approach to description of the patented technology between the two patents?

2. With publication date of June 30, 2016, (it was 2016, not 2017, right?), what might have been the strategic reason for waiting until now for Sigma to release this info? Also, wouldn't this have been a matter of public record since publication occurred, and yet we all just were unaware until yesterday? GE recently released info re their patent publication, right? Did their patent publication also occur last year?


Thank you
