Ronald Katz has sued and won big companies over processes like "routing calls through a call center", or using a telephone to check a bank balance or transfer funds. (IVR) - Interactive Voice Response
While Katz never invented any of these technologies, he decided to patent the process, which was never patented before. He was awarded the patent, but unfortunately for the users of this technology, they were sued. Even though AT&T bell labs invented most of the telephony technology, they never patened the "Process". Unfortunately for them, Mr. Katz did.
