CIPO searches
search just 321/105- or -
search hierarchy!
The "search hierarchy!" link will execute this search:
((321/105 <IN> CPC) <OR> (321/106 <IN> CPC) <OR> (321/107 <IN> CPC) <OR> (321/108 <IN> CPC) <OR> (321/109 <IN> CPC) <OR> (321/110 <IN> CPC) <OR> (321/111 <IN> CPC) <OR> (321/112 <IN> CPC) <OR> (321/113 <IN> CPC) <OR> (321/114 <IN> CPC))
This will show what classes derive from the input. Ex: entering 78/35 shows the derived classes and the search that can be used to find
patents in those subclasses.
