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The website has some seriously outdated search system, oddly the response headers say Apache yet the URL has a .exe in it.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.

Overall good, but the site search results are a mess, and is there some reason why individual sections of the MPEP link back to the main MPEP table of contents but not MPEP chapter tables of contents?

This is the official site of the United States Patent and Trademark Office, where people can apply for a patent for their products.
