B01 PHYSICAL OR CHEMICAL PROCESSES OR APPARATUS IN GENERAL
Description
B01 encompasses apparatus and processes for fundamental physical and chemical operations that are not restricted to a specific technical field or application. This class covers general-purpose equipment and techniques such as mixing, separating, heating, cooling, and drying, along with associated control systems and apparatus designs. Inventions classified here typically serve as building blocks across multiple industries—from pharmaceuticals to food processing to chemical manufacturing—and are inventions that cannot be adequately classified within more specialized B-subclasses dedicated to particular applications or materials. B01 excludes devices designed for highly specific technical applications, which are classified in their respective specialized subclasses (such as B02 for crushing/grinding or B05 for spraying).
IPC and CPC are identically structured here. All 5 subcodes exist in both systems.
2 shared codes have differing titles between IPC and CPC.
