Something Cool
Honestly, it sounds like you have an issue with the patent office, rather than DiMarzio.
Nobody is perfect. The issue is that companies like DiMarzio throw all kinds of crap at the wall and see what sticks. You get a weaker person in the office and it will be extremely hard (a lawsuit) to get rid of the patent or trademark. That's a business model and I don't like it.
