Am386 was reverse engineered design, but microcode was 1:1 Intel copy :). There was no
court battle over this chip. Intel was forced into arbitration due to second source agreements, and lost.
Court battle was over 287 and later Am486. AMD announced clean-room design ... and gave their clean room engineers 386 microcode copy :]
