    Excellent. Downloaded all my old patents.

    I prefer these guys,

    So far I've accumulated about 1000 patents that interest
    me, taking 866MB of disk space. I'm sorry to say that
    I paid $3 apiece for many of them in the bad old days...

    I don't get this - the USPTO has had them online for free
    ever since I can remember the USPTO being on-line. The
    only glitch is that their images are .TIFF format, so
    you used to have to download a reader, but nowadays
    even that probably isn't necessary.

    The benefit of a pdf file is it's just one file, instead
    of one file per page. What a pain!!
  5. Page-by-page images. Yuk. It was worth $3 or $5 each to get them into
    a more useful form, though why the USPTO chose TIFFs rather than just
    putting them online in PDF format is hard to figure.

    For those patents/applications available only on USPTO, I use
    "TiffCombine" to create a single file, then convert to PDF.

    It's what you learn after you know it all that counts.

    Yes, but they only cover US patents.

    Ah. Now I understand.

    Never mind. :)

    Well, I don't remember how I did it, but I have a few patents here in a
    file folder - that's paper, in a Pendaflex - and IIRC they were trivially
    easy to print.

    But, as has been said, the USPTO only has US patents. )-;

    You hit PRINT multiple times as you displayed pages one at a time?

    Now imagine saving each to a different file, then manually combining
    them into one file somehow... Printing is easy by comparison.
  12. I use, but it isn't free (though my
    employer pays ;). For prior art searches is also

    The Europeans made 'em do it. Really. The PCT (Patent Cooperation
    Treaty) specifies the (unusual) storage format, which is .TIFF with
    CCITT Group 4 compression.

    You'd think they could offer '.PDF' conversion, but I suppose their
    servers are already severely taxed as it is...

  14. Easily batchable with wget (to fetch the subsequent TIFFs),
    tiffcp (to make one multi-page TIFF out of the single images) and
    finally tiff2pdf to create the pdf wrapper.

  15. I was supplied with a collection of electronic circuit
    diagrams the other day. The originals in their CAD
    were in PDF form, but they converted them to multipage
    TIFFs for supply to outsiders. They explained that the
    reason was legal, in that it is apparently difficult to
    modify a TIFF without leaving footprints.

    Detemining whether documents have been copied or modified
    could be important in court cases..... theft of IP, or
    assigning blame in the event of an accident, or whatever.

    PDF's can now be locked for similar reasons.

    Sounds sensible enough. Investigated, there usually are rational
    explanations for these requirements.

    The pat2pdf script (don't confuse it with the online version,
    automates that all nicely. It uses either wget or lynx (whichever you
    like) to get the tiffs, then tiff2ps on each, then gs to assemble a
    multi-page pdf. Just one command line action - "pat2pdf <pat #>".

    Obviously, you need to have either wget or lynx, plus tiff2ps, plus gs
    already, for it to work. It's just a shell script.

    Is there a "wget" that ISN'T command-line?

    Wellll....... There *is* a sort of GUI (TCL/TK) frontend (TKwget) that
    sort of makes things a bit easier. Thing is, wget was intended to be run
    in the background unattended, probably as a cron job, for mirroring sites,
    and it has a lot of configurable options. You still need the manual in
    front of you using TKwget. The usefulness of wget is largely in its being
    able to be piped into other applications, as in pat2pdf.

    You can run into real trouble if you give wget the wrong options. Not only
    will it build a replica if a site on your machine, it will follow all the
    links to other sites, and build those, too. You come in in a morning to
    find gigabytes that you didn't want.

    Pat2pdf goes to, finds the tiffs, does the conversion, saves the
    pdf and quits cold, I'm glad to say.
