Re: Seymour Duncan '59
I use the Dimarzio Fred and I'm pretty sure it has mis-matched coil resistance readings..

It's long expired. Besides, DiMarzio only held a patent for a certain kind of asymmetrical coils. Lots of winders do various "mismatched" coils, one being the Pearly Gates; one coil is a little hotter than the other. Some are more radical.
Heck, I'm now in love with the Custom/59 hybrid I made for my guitar. Asymmetry Heaven!!!

Ah, thanks for clearing that up, man. I'd heard that about the Pearly Gates before but I wasn't aware that anyone had confirmed it. It's only a slight mismatch, yes?

It's a trademark, not a patent. They can't patent a concept, only a specific design and process, which means they would have to patent every possible coil winding and their infinite combinations separately.
For example they can patent a 2-coil pickup where the inner coil reads 6K and the outer coil reads 5K, and when wired in series the whole pickup would read roughly 11K, but that patent would not cover the inner coil being wound to 5K and the outer coil to 6K, thus being the same pickup spec-wise.
However, they can trademark the concept of mismatched coils, provided it is recognizable by the general public as being most-commonly associated with DiMarzio (according to the regulations of trademark, which I looked up a while back for my own purposes).
I do believe they held the patent on the double-cream bobbin configuration, however. That's something that could be trademarked as well, since it was one of their defining visual characteristics that the general population would know (at least in musical circles).

Dimarzio's control over mismatched coils is a patent, not a trademark, and covers a certain type of mismatch: roughly the same number of turns of wire, with different wire types (guage, IIRC) on each coil. Thus if they were able to wind about 1000 turns of 42AWG on one coil and have it read 5k while winding about 1000 on another and have it read 6k, it would matter which coil is is inner or outer or magnetic north or magnetic south. Both would be covered by the patent.
Their lock on double creme bobbins is a trademark.
