G01G WEIGHING (sorting by weighing B07C5/16)
Description
G01G covers apparatus and methods for determining the mass or weight of objects through mechanical, electronic, or combined measuring systems. This includes weighing scales of all types—from simple balances and spring scales to sophisticated electronic load cells and digital weighing instruments used in commercial, industrial, laboratory, and domestic applications. The classification encompasses the design, construction, and operation of weighing mechanisms, as well as auxiliary devices for display, control, and data processing integrated with weighing systems. Related measurement of physical properties derived from weight (such as density or concentration determination by weighing) falls within this scope, though purely gravitational measurements are classified elsewhere in G01M or G01N.
Filing statistics
CPC subclass G01G recorded 33,993 patent applications worldwide between 2013 and 2023. Annual filings grew from 1,435 in 2013 to 2,977 in 2023 (+107%), peaking at 4,418 applications in 2020. The most active applicants in class G01 are CHINESE ACADEMY OF SCIENCES (21,460 applications), ROBERT BOSCH (17,801 applications) and SGCC(STATE GRID CORPORATION OF CHINA) (17,347 applications).
