From gpt doesn’t make a whole lot of sense
As of my last update in January 2022, I don't have specific information on all the companies Vcsy has asserted its patents against. However, Vcsy, also known as Virtual Communication Services, Inc., has been involved in various legal battles over its patents related to technologies like smart compilers and virtual communication systems. Some of the companies it has targeted in the past include major tech firms such as Microsoft and Google, among others. It's essential to check the latest news or legal filings for the most up-to-date information on any ongoing patent litigation involving Vcsy.
