I would like the patent numbers for patents by people who live in
Austin Texas for the last five years where the patent is not assigned
to any other entity/company.  The vast majority of patents are by
people who work for a company, and the company owns the patent-- I am
not interested in these patents.  I would like the petents only where
there is no 'assignee', or where the assignee is the same person as
the inventor. However, I am pretty sure that there will be no assignee
listed for patents where the inventor is the  assignee. I am familiar
with a couple sites that let you search patent info--- but do not know
how to obtain these specific results.  So, a reference to a site that
let's a person search patents, but would not allow these speciifc
results is not a good answer to this question. There are a large
number of patents for people in Austin for the last five years--
however, limiting to patents where there is no entity as an assignee
dramatically reduces the number.
To rephrase in differant lingo-- I would like patents where the person
who has the invention is the same person who owns the idea. Feel free
to ask clarifying question if helpful.
Thanks!

Unless I am interpreting the second comment in correctly-- this will
not answer my question. I wish to pull up **only** patents where the
assignee is the invetor, or patents where there is not assignee (for
austin inventors in the last five years) . I can easily do a serach
fot patents by Austin inventors, then open each one individually do
look at each one to see if it meets the criteria(inventor is same as
assignee, or no assignee..). Since hundreds and hundres of patents are
for austin invetors from the last five years-- it would take a very
very long time to do this....I would have to manually open every link
returned in the query to see if it is one where inventor is same as
assignee-- or no assignee. I see no way using the links provided to
return only the results I want-- not the hundreds and hundred of
austin patents in the last five years..

This is interesting, only that the actual query for getting this info
from a traditional database would be trivially easy. Assuming it's in
only one table (that would be odd though.) Assuming the columns
intuitively named:
SELECT * from 'theTable' WHERE InventorCity = 'Austin' AND Assignee IS null

But---- there databse does not allow such 'bare metal' queries, and
transforms your query-like syntax into the real SQL (query)on the back
end..

Or perhaps it can be stated as "where the inventor is the same as the
patentee (patent holder)?"

That's an easy question...

Search here by limiting the data info to the city and state you are looking for:
http://164.195.100.11/netahtml/search-bool.html

Then look to see if there are any assignment changes here:
http://assignments.uspto.gov/assignments/q

Have a great day!

Regarding your April 15, 2004 follow-up...no single database exists
that will provide you with a current listing of patents held by the
original owners sub-listed by geographic areas within a five year
period.  I would suspect that you could hire a computer "guy" to build
you a software program that could run the two steps I provided from
the 14th.

The reason that such a database listing of the sort you are seeking
does not exist is because there has never been a need.  Typically if
someone is interested in a single patent, they search that patent to
see who currently owns it.  A group by geographic region and by a
given year span!?!?!  Not a typically query.

The two links I provided are USPTO records.  That is all there is...as
of today's date.

I wish you well!
