The circuit I use is only partially the same as other people's products. This product is not a pure circuit product, but has control software. The instructions of the core microprocessor are completely incompatible, and the running mode and display interface are very different. Of course, the function achieved is still similar. Is there any way to avoid each other's protection?
It is puzzling that it is very common for electronic majors to learn from each other, and most of them are the combination of basic circuits. If someone protects all the basic circuits, then no one else will be laid off.
This is a patent.
For circuit design, it can be protected by integrated circuit layout design and/or patent.
For integrated circuit protection, if your circuits have the same principle and different structures, it is impossible to infringe.
For patents, it is not simply to compare your circuit with the patented circuit. You should compare your circuit with the technical scheme recorded in the claim.
