URI for patent is actually URI for search (not optimal)


What might a URI for a patent look like?

   http://www.uspto.gov/patents/p6678889

Note that this is globally unambiguous; better than "6678889"

Search produced this URI for search on "hypertext":

   http://patft.uspto.gov/...s1=hypertext&OS=hypertext...

Search produced this URI for search by patent number 6,678,899:

   http://patft.uspto.gov/...s1=6,678,889.WKU....

Why are these URIs different if this is the same patent?
