Santa Clara county was sued successfully, but not on a federal level. State
of California has the same PD rules and this can be used only for California
state and county data.
Don't have the link available right now but it can be found in the archives
of talk-us
But still you may need to check data offered at CASIL website. It is a mix
of state and data provided by private companies. One example is Greeninfo
data which is not PD.
