25.1 Image data in patent databases
Patent databases containing images: DWPI, FRANCEPAT, FRFULL, GBFULL, EPFULL, JAPIO, KOREAPAT, PATDPA,
PATDPAFULL, PCTFULL, RDISCLOSURE, RUSSIAPAT.
In PATDPAFULL there are plans to introduce images.
All databases (except CA/CAPLUS) have an entry GI in the Field Availability (/FA) field if a record includes a patent
image:
=> S L1 AND GI/FA
The Graphics Information Size /GIS field holds the image size:
=> D 1-3 GIS
The images are displayed with the GI field or as part of a predefined display format (BIB.G, MAXG, etc.).
Patent images are stored in these formats:
Image Format File Extension
TIFF .tif
JPEG .jpg
GIF .gif
Structure Image .gra
The images can be transferred using STN Express or STN on the Web. The images are displayed in the document
context. When using STN Express the images may also be displayed in a separate window using the TIFF Viewer.
With STN Express, version 8.4 or later, the images are transferred faster than with previous versions. With STN on the
Web the transcript files with images should be saved as RTF (Rich Text Format).
25.2 CA/CAPLUS
The TIFF or GIF images of the scanned pages from the printed Chemical Abstracts of the years 1907 1966 can be
displayed in CAPLUS. The DISPLAY formats are: PAGE, PAGE.NEXT, and PAGE.PREV. It is a good idea to use STN
Express or STN on the WEB.
25.3 DWPI
The DWPI database contains patent images (technical and chemical structure drawings):
Engineering: from Derwent week (DW) 8801
Chemistry: from Derwent week (DW) 9201
Generally, a record holds no more than one patent image. It is, however, not necessarily the drawing from the title
page of the patent document. Sometimes, however, there may be more than one patent image.
Images in DWPI are scanned at 300 dpi. Images are displayed in the GI or GI.M display fields.
Additionally, there is a number of display formats that include images and where the image is displayed at
invention level: e.g. ALLG, BRIEFG, FULLG, MAXG. To obtain an image and its respective Member at publication level
the MEMBG or MEMBFG formats can be used.
