COOPERATIVE PATENT CLASSIFICATION
​​
D04B
KNITTING [2019-01]
NOTES

  • In this subclass, the groups designating machines, apparatus, devices, or implements include processes characterised by, or dependent on, their use and the products of such processes
  • Knitted products, i.e. fabrics, articles, are classified in this subclass only if they have constructional features which are of interest from the knitting aspect
  • In this subclass, further classification in indexing scheme D10B for aspects relating to textiles is required.
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.
