CPC: for the manufacture of piezoelectric or electrostrictive resonators or networks (H03H3/08 takes precedence)

Full Title

Full titles differ between systems:

IPC:

Apparatus or processes specially adapted for the manufacture of impedance networks, resonating circuits, resonators > for the manufacture of electromechanical resonators or networks > for the manufacture of piezoelectric or electrostrictive resonators or networks

CPC:

CPC subdivides this area 8x more granularly than IPC with 7 additional codes.

7 codes are CPC-only extensions.

Note: 7 CPC extensions are marked as secondary classification only.
