Hi:

I am trying to extract data form the US Patent database (patents.uspto.gov).
I am using the LWP::UserAgent module to retrieve results from a search,
I then parse the resulting html for links which I then follow to download
data on the patents.  the problem i'm having is that some of the links look 
like the following (if i do view page source) 
http://patents.uspto.gov/cgi-bin/ifill4?INDEX+0+27061+1+50+166+OF+4

however when i try to extract this link the 27061 is always a different
number as is the 166 and the OF changes to a B.  so clearly when i try
to link to the page i get an error message.  

i've tried to retrieve the links by just searching the html code and
also by using extract_links and i have the same problem with both.

any thoughts?

Thanx, Angelique.
