Marking Stainless for food grade and hi temp

I have developed a way of putting a minimum 3 mil depth marking -n stainless (not on the surface) any color any shape.  Am able to accomodate acute edging and detail and can do this on convex or irregular surfaces.  The marking will meet food grade standards, high temp to 1500 deg, and medical grade marking. Marking is flush with surface.

Not sure on how to market or license the process.

Any advice would be appreciated.  This will accomodate large logos, or detailed graphics, it is not a laser system.

Thanks,
