Title

Titles differ between systems:

IPC: using the flow of water resulting from wave movements, e.g. to drive a hydraulic motor or turbine

CPC: using the flow of water resulting from wave movements to drive a motor or turbine

Full Title

Full titles differ between systems:

IPC:

Adaptations of machines or engines for special use; Combinations of machines or engines with driving or driven apparatus; Power stations or aggregates > characterised by using wave or tide energy > using wave energy > using the flow of water resulting from wave movements, e.g. to drive a hydraulic motor or turbine

CPC:

Adaptations of machines or engines for special use; Combinations of machines or engines with driving or driven apparatus (if the apparatus aspects are predominant, see the relevant subclasses for such apparatus, e.g. H02K7/18); Power stations or aggregates (incorporating only machines or engines of positive-displacement type F03C; hydraulic engineering aspects E02B; ) > characterised by using wave or tide energy > using wave energy > using the flow of water resulting from wave movements to drive a motor or turbine
