No.  Steve Ward indeed DID "invent" the ISSTC.  I am pretty sure Mark Barton
didn't have a series tank cap, which is the MAIN difference between an ISSTC
and any normal interrupted tesla coil.  It might be good for you to do an
exhaustive search,  but all you have to do is read Steve's website for a
second and see that he indeed did design and compile the ideas which I would
say was inventing.

Not to mention how he used quotation marks around "invent" which might
suggest that's not exactly what he meant.
