Hi,

As i know, the 8051 patent granted by intel had been expired last year. So it should be OK now.

Hope it helps : )

Should be no problem if you want to write 8051 core

There area lots of IC provider sell the 8051 IP so the patient should be not an issue anymore

As I know, Intel still hold the patent on 8051's I/O port structure, but that on micro-code was expired. As long as you do not make use of the same I/O port structure, it should be no patent issue.
