* * * * * * * * * * * * * The Derwent Manual Codes are assigned to patents by Derwent抯 indexers. They are used to indicate the novel technical aspects of an invention, and also its applications. Using Manual Codes to create a detailed search strategy can significantly improve the speed and accuracy of searching. Manual codes are arranged in hierarchies where there is a broad or general code at the top of the hierarchy followed by subdivisions of the codes into more and more specific categories. For example, the manual code J07 is defined as Refrigeration; ice; gas liquefaction/solidification. The manual code is broken down into four subdivisions: J07-A – Refrigeration machines, plants, or systems, combined heating and refrigeration systems J07-B – Freezing of (semi)liquids J07-C – Refrigerators, cooling, and freezing apparatus J07-D – Gas liquefaction, solidification, or separation by pressure or cold Each of these is further broken down into more specific subdivisions. For instance, J07-B02 is specifically about ice or snow production for special purposes. When searching using the manual codes, it is important to use the asterisk truncation character. For example, searching for J07-B will yield a different set of patents than searching for J07-B*. (J07-B will find patents that have not been assigned to one of the subdivisions within the J07-B hierarchy, while J07-B* will find those patents as well as all patents within all subdivisions in the J07-B hiearchy.)
