Viewing Patent Drawings
Thumbnail or Representative Images
Depending on the display options chosen by the user, Delphion can include representative (or “thumbnail”) images for patent documents directly in the hit list. These are usually images that appear on the patent front pages, which in turn are chosen for each publication by the applicant or examiner. By allowing images to be present on the hit list, Delphion aids users who wish to scan images for relevant content without having to load each patent document. This is especially useful to searchers in the mechanical arts.
Although exact coverage for these representative thumbnail drawings are not known, they appear to be present for some United States (US), and United Kingdom (GB) and Japanese (JP) documents. Instead of representative drawings, patent front pages are shown as thumbnails for Patent Cooperation Treaty (PCT/WO) and some German (DE) records.
Derwent records also have associated thumbnail images, which may differ from those images shown for the non-Derwent records from the same patent family. The reason is this: as part of the indexing process, Derwent indexers select the best representative image for display in the Derwent file from among the Basic document’s (first family member’s) drawings. Thus, the drawing chosen by the indexer, and the drawing chosen as the representative image by the applicant or examiner, may be two different images out of the document’s drawings. To view the Derwent-selected image for a patent office record, users must actually purchase the Derwent record for that document, from the integrated view. The cost for a Derwent record is $6 each.
Full Document Images
When viewing full text records from the integrated record view, searchers also have the opportunity to view full document images for free on Delphion. These are loaded into an Acrobat viewing window that permits single document pages to be viewed saved, or printed individually. These documents appear to be hosted on Delphion’s own servers, as opposed to being hosted by espacenet or the USPTO website.
