ANALOGUE COMPUTERS

Introduced: September 1968

Classification Context

Section:
PHYSICS
Class:
COMPUTING OR CALCULATING; COUNTING
Subclass:
ANALOGUE COMPUTERS

Description

G06G covers analogue computing devices and systems that process continuous physical quantities (such as voltage, current, mechanical displacement, or fluid pressure) to perform mathematical operations and solve problems. This subclass encompasses analogue computers using electronic circuits, mechanical components, or hybrid technologies for applications including differential equation solving, simulation, control systems, and scientific computation. The classification excludes digital computers (G06F) and hybrid systems primarily classified elsewhere, focusing instead on machines where the computation directly represents mathematical relationships through proportional physical phenomena.

Filing statistics

IPC subclass G06G recorded 5,173 patent applications worldwide between 2013 and 2023. Annual filings declined from 842 in 2013 to 177 in 2023 (-79%). The most active applicants in class G06 are SAMSUNG ELECTRONICS COMPANY (66,669 applications), IBM (INTERNATIONAL BUSINESS MACHINES CORPORATION) (62,313 applications) and MICROSOFT TECHNOLOGY LICENSING (41,918 applications).
