Dr. Xiao was invloved in multiple civil lawsuits in the US too. Here they are:

Court: Bronx Civil Supreme
Index Number: 001374/1993
Case Name: XIAO,CHUANGUO vs. WARDEN
Case Type: Other Torts

Court: New York Civil Supreme
Index Number: 100153/2003
Case Name: XIAO, M.D., CHUAN-GUO vs. CONTINUUM HEALTH PARTNERS
Case Type: Other Torts

Court: Kings Civil Supreme
Index Number: 022422/1997
Case Name: CALI,LUCY AVELENDA & ROSS vs. XIAO,CHAUN GUO
Case Type: Motor Vehicle

Court: New York Civil Supreme
Index Number: 072143/1992
Case Name: YUAN, WEI vs. XIAO, CHUANGUO
Case Type: Contested Matrimonial

Note the first one, XIAO,CHUANGUO vs. WARDEN. It seems that Dr. Xiao did not enjoy the time behind the bar.

One more.

This one shows under what circumstance did Dr. Xao invent his procedure in the US:
http://vlex.com/vid/chuan-guo-xiao-continuum-18536135
Plaintiff alleged that LICH discriminated against him on the basis of his Chinese national origin by terminating his employment as a research director; by forcing him to work in a laboratory that was used for the storage of paint, tiles, and windows; by refusing to relocate him from a building that was closed by LICH; by not providing him with a contract; and by not paying him for work he performed in China.

I hope my posts could help you to learn more about Xiao Procedure and himself and the Beaumont trial, especially for those on this forum who are interested in the procedure and have received response from Beaumont.
