[SEL] patent search

[Frank DeWitt]

It has been a long long time since I did a patent search but as I recall 
You could search by multiple inputs  such as subject category  (a 
number)  assignee,  and range of dates.  This what not on the Internet. I 
did it at one of the  Libraries that house patent info.  I used the one in 
Buffalo NY.  The librarians were very helpful in getting me started. I 
don't recall if the old stuff was computerized at that time.  This site 
might help you.
Patent and Trademark Depository Library Program 
(PTDLP)  http://www.uspto.gov/go/ptdl/

   I haven't tried it since.  In the other patents I have, I had the luxury 
of some one else paying for the search (and being the assignee).

BTW  if any one with a slow country connection wants a Direcway satellite 
hook up email me I have one for sale.
