MEDICAL OR VETERINARY SCIENCE; HYGIENE

Description

A61 encompasses inventions and technologies in medical and veterinary diagnosis, treatment, surgery, and hygiene. This broad class includes medical devices, surgical instruments, therapeutic methods, prosthetics, dental equipment, and hygiene products for both human and animal healthcare. Related inventions in pharmaceutical formulations (A61K), physical therapy and rehabilitation (A61H), and medical diagnostic apparatus (A61B) are classified within this section, while chemical compositions themselves are typically handled in section C.

IPC and CPC are identically structured here. All 13 subcodes exist in both systems.

9 shared codes have differing titles between IPC and CPC.
