SUBJECT MATTER NOT OTHERWISE PROVIDED FOR IN THIS SECTION

Description

A residual classification for inventions and innovations within the textiles and paper domain that do not fit within the established Classes D01 through D98. This class accommodates emerging technologies, interdisciplinary developments, or specialized applications in textiles and paper manufacturing that predate or fall outside the scope of existing systematic classifications. Patent examiners use this class when the primary technical character of an invention relates to textiles or paper but lacks a clearly defined home in the defined subclasses.

IPC and CPC are identically structured here. All 1 subcodes exist in both systems.

IPC defines codes here since 2006.
