Guitar Patent
Patent Question: Filters?
Say I want to build something like a Preamp for a guitar amplifier and market it. When designing the treble and bass control section of the circuit, you use a lot of common knowledge filters and such to do this. Even you’re most basic textbook filters hold patents….and I know not every guitar amp has a completely diff treble and bass control to get around the patents. How do I put a passive low/band/highpass filter configuration in a system legally?
If a patent ever existed on any one of these devices, it’s a very good bet that it expired years before it was published. Patents generally provide protection for 20 years, after that the idea is public domain. Although you can find very good circuit ideas in books, every circuit usually becomes unique when it is applied to your specific gizmo.
