PDF Patent Documents

You need the Adobe Acrobat Reader to view these Portable Document Format files (click the link for the free software). They are large files (some over 3 Megabytes). Unless you have broadband access, you'll have to be very patient while they download (go and make a cup of tea).

If you experience difficulties viewing them in your browser, try downloading the zipped files to your hard-drive by clicking the Save icon icon.

Alternatively, you can buy the Patents CD.

Although the original format of the documents is accurately retained, the reproduction quality of some of the earlier patents leaves something to be desired. They will be replaced if better copies are obtained.
