I don't, but it's certainly possible. Most employers have no desire to sue employees, so most of these settle or get ignored, AFAIK. At least in the case of Google (literally, i have no concept of other Alphabet companies), the only cases i'm aware of where Google has claimed it owned something was when the employee sued Google first. example: A former employee suing Google over a patent developed while employed by Google, google counterclaims it owns that patent under the IP agreement.
