I'm not sure when that patent officially expired, but I've had the same kind of though myself. I think itmight have been good for 14 years back then.Not that I read this whole thread, but why can't Gibson trademark silver and gold covered humbuckers and stick it to Dimarzio?
Hell, why didn't Gibson sue Dimarzio for patent infringement back in the day? Wasn't that a 20 year patent?
Why can't they trademark silver/gold covered humbuckers? Because that is way more than aesthetics. The over shields from elecromagnetic interference and provide further protection to the coils. It's not just for looks.
