Kevin Kimberlin, Spencer Trask, and David Buswell, Immune Response

I have writen to Immune Response Biopharma and Spencer Trask several times asking if Spencer Trask or Kevin Kimberlin were involved in the financial support or creation of the Immune Response Biopharma company which is now laying claims to the research financed by the investors of Immune Response Corportation and Orchestra Therapeutics, Inc. The only response I have received back is threatening letters from David Buswell. They refuse to say if Kevin Kimberlin and Spencer Trask is involved in Immune Response BioPharma or not. I wonder what to make of that.
