According to SciFinder, the viewer:
Presents searchable, full text of patents with interactive indexing and annotations that inform the user’s research
Offers direct links to and from SciFinder that promote serendipitous searching and exploration
Find out more about the document viewer here: http://www.cas.org/products/scifinder/patentpak/viewer.
As I have blogged before, registered SciFinder users are currently entitled to five free samples of PatentPak content.
When you click on the PatentPak icon (that will appear in your search results) you can immediately view the full text patent document for that reference. A pop-up box tracks how many free samples are still available. If you click on the icon after all five free samples have been used, you can still link to more information about PatentPak.
The substance location information feature within the SciFinder patent display is not included in the complementary access although availability is noted in the display.

Want to recommend PatentPak for purchase?
If you take advantage of any of the free content samples and consider that adding PatentPak to our existing subscription to SciFinder would be worthwhile, please contact me at email@example.com.
