In september 2010 Patstat data we find a 'new' IPC class, starting with G01Q.
http://v3.espacenet.com/eclasrch?classification=ecla&locale=en_gb&ECLA=g01q
example:

Such code was not previously reclassified, so, thanks to the suggestions of Emmanuelle Fortune from CEPS,
G01Q could be classified in the new Wipo35 technology classification as follows:
(G01Q# not G01Q70/12) in the number 12 "control" (that was class 7 (Technologies for Control/Measures/Analysis) in OST 30 reclassification)
G01Q70/12 in the number 22 "Micro-structure and nano-technology" (that was class 5 (semicond+nanotech) in OST 30)
You can download from this link OST30 reclassification in XLS format, updated with G01Q.
