When reviewing search hits, TotalPatent can display all patent drawing images alongside the electronic patent full text; this feature can be found under the “Images” display when reviewing search results. According to a TotalPatent representative, drawings (clipped, inline, and other images) are available for more than half of the authorities covered in TotalPatent. However, full sets of patent drawings are only available for two of TotalPatent’s collections: US published applications and granted patents beginning in 2001, and EP published applications and granted patents from 2000. Note that full drawing images are not comprehensive; drawings may be missing for some US or EP documents that fall within these date ranges.
When full patent drawings are unavailable for a given record, the system is often able to provide at least one representative drawing image, known as a “clipped” image, for major patenting authorities. A 2010 coverage table from LexisNexis lists that clipped images are available for the following full-text authorities (the table also lists the earliest available dates for full-text and bibliographic coverage, which can be found in the Comprehensive Coverage Table):
According to data provided by a TotalPatent representative, over 40 million clipped images are available on TotalPatent, from the collections of 56 patenting authorities.
Within the Comprehensive Coverage Table, it is likely that the "other images" coverage mentioned under the "Image Availability" column is referring to clipped images.
Another benefit of TotalPatent is that the system’s data collections often will include the full patent facsimile image, with coverage at least equal to that available from Espacenet. These PDF images may be viewed through the system without the need to download the document; the Results display page offers a “PDF” option which will load the document in an Adobe viewer from within the TotalPatent system. Although viewing the patent copy does not always lend itself to quick image skimming, it is at least an alternative way to review patent drawings if necessary. PDF images of some kind ("Facsimile PDF" or "Facsimile plus front page" as listed in the coverage table) are available in 54 different authorities.
Finally, in the case where a TotalPatent record has no available drawing sets, clipped images, or PDF facsimile image, users should check the family data to determine whether the record of interest may have a TotalPatent family member fitting this date and country criteria, for which image(s) may be present. More about family data in TotalPatent is discussed in the next section.
