The plaintiff Mod Stack is based in McKinney.
It assumes ownership of the United States Patent Number 7,460,520 entitled “Apparatus and Method for Using Multiple Call Controllers of Voice-Band Calls.”
Per recent court documents, the invention of the ‘520 patent is generally directed to systems for supporting multiple call controllers of voice-band calls.
“The inventors therefore invented the apparatuses and methods disclosed in the claims of the ’520 patent,” they say.
Mod Stack seeks unspecified monetary damages and a jury trial.
It is represented by attorney David R. Bennett of the law firm Direction IP Law in Chicago.
