FWIW: This appears to be his startup: http://www.myliferesponse.com/ and from his resume, it appears he's the business/marketing partner in this relationship.

for "Life Response" owned by Midwest Medical Alert Systems, Inc. CORPORATION ILLINOIS 269 Winding Creek Drive Naperville ILLINOIS 60565.
The weird thing is, the business using the http://www.liferesponseusa.com domain is "Life Response USA" and they're a division of CTR Alarm Systems Inc. --- a Pennsylvania Corporation. So that's odd: not the same company as the trademark holder?
More research is needed.
I would make the guess that liferesponseusa.com is not the same business, based on the different addresses you brought up. I wonder if they're looking at a similar situation with the trademark holder.
