USPTO approves too many junk patents. See https://www.eff.org/deeplinks/2015/03/eff-asks-pto-stop-issuing-abstract-software-patents
The website has some seriously outdated search system, oddly the response headers say Apache yet the URL has a .exe in it. Maybe Apache is being used to reverse-proxy to sole very old system.
It requires you to click a Logout button when done searching, and cannot be searched from public search engines like Google, or give permalinks to trademark records.
