TRANSPORTATION CODES
As part of the ongoing development of our manual coding system, extensive and detailed manual code hierarchies have been developed for sections of the mechanical Derwent Class Q, and are now being applied to patent records.
The new mechanical codes cover all areas of transportation – including automotive, aerospace, railway, and shipping technologies, and are applied consistently to relevant patents across all of the countries currently covered in Derwent World Patents Index® (DWPISM).
The addition of manual coding improves recall and precision when searching Q Classes, and also enhances any subsequent data analysis of particular subsets of a technology.
There are no plans at present to apply codes to records prior to 2006.
Examples of the new codes for the Q11 and Q14 areas are:
Q11-B05 Tyre sidewalls
Q14-C02 Inflatable occupant restraints (e.g. airbags, knee bolsters, side/curtain airbags.
