Chrome stopped working to download PDFs from USPTO's PAIR web site, says download "Interrupted" robertks 6/16/11 8:34 AM
I don't know whether the problem is on Google's end or on the USPTO's end, but sometime in the last week it became impossible for Google Chrome to retrieve (download) PDF documents from the USPTO's PAIR web sites.  Try to download, and the file download indicator says "Interrupted".  I have to switch over to Internet Explorer anytime I want to use PAIR and download files.

It is still possible to merely view the PDFs in Chrome (i.e., without downloading the file) but if I want to retrieve a file that way, I have to save each individual page as its own PDF file, which is a hassle.

I have an e-mail into the Patent Office on this issue, but I would appreciate some word from Google if the problem might be on their end.  The issue arose quite suddenly, after working well for years.

Google Chrome version (type about:version into the address bar): 12.0.742.91 beta-m
Operating System: Windows XP Pro
Error Message: "0.1/XX.X MB, Interrupted" (in file download bar)

Here is the official Patent Office response I received from the USPTO's Electronic Business Center:

"The google chrome is not one of browser that we support.
If this problem continue to exist then you many need to use IE or firefox instead.

Thanks

I should add that I find it interesting that the Patent Office has no interest in supporting Google Chrome despite USPTO/Google partnerships in a number of areas.

Hello - It's not a USPTO issue.  I get the response, 'interrupted,' on other site.  Using IE, the pdf downloads as expected.  Using Fiddler to monitor the traffic in both IE and Chrome, the packet sizes are the same for both responses - meaning, the pdf and it's content are delivered; however, Chrome responds with a similar '138001/0 B, Interrupted' error.  It looks like the content is available, but Chrome is having issues uncompressing the response.  I'll post back if I find the solution...

Yes, here is another thread describing an identical problem:

This is an ancient problem and it probably has to do with the way that the PTO formats its PDF downloads to look about 5 times too big. It just wasn't an issue before because you couldn't even get to the download tab in Chrome due to other bugs in PAIR.  You can use an IE Multitab extension and it will let you download properly without booting you from your session.

I have no idea what you mean by "It just wasn't an issue before because you couldn't even get to the download tab in Chrome due to other bugs in PAIR."  Chrome worked great before version 13.  Luckily, the issue has been fixed in dev 14.  http://www.chromium.org/getting-involved/dev-channel to download dev 14.

I didn't have this problem until upgrading chrome. They must have done something different to trigger this problem.

Yes, Google is aware of this problem. Please join the discussion below for updates from users like me and from the Chrome team.

A fix is available in Chrome 14 dev. You can either wait for it to become stable, which is expected to come later this year; or you can upgrade to Chrome dev or install Chrome Canary. Just remember that dev and Canary are both less stable than the stable or beta channels, so watch out for unexpected bugs.

Download Chrome Canary (PC and Mac only) (installs separately from other Chrome installations): http://tools.google.com/dlpage/chromesxs

Hope this helps!

If you are trying to view the PDF document on the USPTO site, you need a plug in for the browser.

From USPTO site...
http://patft.uspto.gov/help/images.htm#req

PTO's full-page images, nearly four terabytes overall, are stored and delivered at full 300 dots per inch (d.p.i.) resolution in an image file format called "TIFF," using CCITT Group 4 compression. This is the format which is required by the international standards to which all patent offices must conform. TIFF is also the most used lossless image format in the world. Unfortunately, due to the volume of the image data, available funding, and other technical considerations, PTO cannot convert these images to a format more popular on the Web either permanently or by converting on-the-fly as they are delivered.

As a result, you must install and use a browser plug-in -- similar to those required to access Adobe® PDF files, RealPlayer®, or Macromedia Flash® files -- on your workstation in order to view these files directly. An alternative method is to use third-party software or services to view these images either directly or after conversion to another format, such as Adobe® PDF.

The plug-in you use cannot be just any TIFF image plug-in. It must be able to specifically display TIFF files using ITU T.6 or CCITT Group 4 (G4) compression.  

The only free, unlimited time TIFF plug-ins offering full-size, unimpeded patent viewing and printing unimpeded by any advertising on Windows® x86 PCs of which we are aware are:

AlternaTIFF:  http://www.alternatiff.com/ (tested: IE, Netscape, Opera)
interneTIFF:  http://www.internetiff.com/ (tested: IE, Netscape)


Google Chrome fails to use AlternaTIFF
Some versions of Chrome, and probably also Safari, have a bug that often prevents TIFF plugins from working.

Whether the bug occurs depends on technical details, such as whether the <embed> tag included a "type" attribute. It also depends on whether the plugin's name contains the word "QuickTime".

The only known way to work around the bug is for AlternaTIFF to include "QuickTime" in its name, but doing this causes other problems. The problems are fairly minor, but we don't want all our users to have to put up with them.

So, we're offering an alternate version of AlternaTIFF for use with Chrome. If you use Chrome, we recommend installing this version:

•alternatiff-pl-w32-2.0.2-chrome.exe
http://www.alternatiff.com/distribution/alternatiff-pl-w32-2.0.2-chrome.exe


Good Luck!
