COOPERATIVE PATENT CLASSIFICATION
​​
B62K
CYCLES; CYCLE FRAMES; CYCLE STEERING DEVICES; RIDER-OPERATED TERMINAL CONTROLS SPECIALLY ADAPTED FOR CYCLES; CYCLE AXLE SUSPENSIONS; CYCLE SIDE-CARS, FORECARS, OR THE LIKE [2020-02]
NOTES

  • In this subclass, each of the main groups B62K 7/00 - B62K 15/00 takes precedence over all the preceding main groups, e.g. a child's bicycle is classified in B62K 9/00 and not in B62K 3/00.
  • {"Cycles" includes a single or plural wheeled straddle type vehicles having a handlebar, self-balancing vehicles and kid scooters}
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
