The U.S. Patent
and Trademark Office
has a great deal of information available to the public concerning the
obtaining and maintenance of patents, as well as search facilities for
issued patents and published patent applications. The Office does not
offer legal advice.
If you need to download a U.S. patent or patent application
publication, a little website called pat2pdf will
make a PDF document for you as needed for free.
