Korean Epiphone Broadway and Guild x-500 (and D-55) fretmarkers?

Why do these guitars have VERY similar (if not identical) fretmarker inlays? Excuse the duplicate pic.

The V-block inlays were Epiphone's design that pre-dated Guild. So, Guild is actually the "copy cat" here.

I did have a hunch that this may have gone back to the old guild-epiphone moment in time. I do think the design is attractive on both guitars. Thanks.
