(Followup — USPTO did the right thing and stopped publishing IP addresses. See this blog post.)
Those who read the previous posting, about the need for USPTO to implement SSL and PFS on all of its outward-facing e-commerce systems, will have heard of the suspicion that a company is eavesdropping on TESS sessions and then uses the results of the eavesdropping in emailed sales pitches. The alert reader will wonder how it is that such an eavesdropper would be able to figure out what email address to use to reach someone at an otherwise seemingly random IP address. The answer is that the US Trademark Office needs to stop publishing IP addresses linked to email addresses.
