TLS 1.0 Retirement

TLS 1.0 Retirement

On the morning of July 16, the USPTO will stop supporting TLS 1.0 on www.uspto.gov This will have very little impact on USPTO website visitors. TLS 1.0 support has already been removed from many commercial websites and is currently being removed from all U.S. government websites. It is only required by older browser versions, most of which are no longer used. TLS 1.0 was succeeded by TLS 1.1 in 2006 and then TLS 1.2--the current standard-- in 2008.
