I think some of these patents are pretty bogus. 
Take this patent for example:<p><a href="https:&#x2F;&#x2F;patents.google.com&#x2F;patent&#x2F;US7660417B2&#x2F;en" rel="nofollow">https:&#x2F;&#x2F;patents.google.com&#x2F;patent&#x2F;US7660417B2&#x2F;en</a><p>Is this a patent for an encryption handshake? I&#x27;m pretty sure I can find very similar flowcharts in my security textbook from 2002.<p><a href="http:&#x2F;&#x2F;www.slashroot.in&#x2F;understanding-ssl-handshake-protocol" rel="nofollow">http:&#x2F;&#x2F;www.slashroot.in&#x2F;understanding-ssl-handshake-protocol</a>
