classification-symbol 

A CPC symbol made up of the following consituent parts, constrained by the cpc-symbol-type
          					
SECTION: Sections are the highest level of hierarchy of the IPC Classification. Each section is designated 
by one of the capital letters 'A' through 'H' as recommended in WIPO Standard ST.8, with the addition 
of section 'Y'.
           					CLASS: Each section is subdivided into classes which are the second hierarchical 
level of the IPC Classification. Each class symbol consists of the section symbol followed by a two-digit 
number as recommended in WIPO standard ST.8.
            					SUBCLASS: Each class comprises one or more 
subclasses which are the third hierarchical level of the IPC Classification. Each subclass symbol consists 
of the class symbol followed by a capital letter from 'A' to 'Z' as recommended in WIPO Standard ST.8.
            					
MAINGROUP: Main Group consists of one- to four-digit number (1 to 9999) as recommended in WIPO Standard 
ST.8. This field can be blank, if classification level is 'S' (classification in subclasses only)
        					
SUBGROUP: Subgroups form subdivisions under the main groups  the IPC Classification. Each subgroup consists 
of two- to six-digit number (00 to 999999) as recommended in WIPO Standard ST.8. This field can be blank, 
if classification level is 'S' (classification in subclasses only).
