COOPERATIVE PATENT CLASSIFICATION
G01D
MEASURING NOT SPECIALLY ADAPTED FOR A SPECIFIC VARIABLE; ARRANGEMENTS FOR MEASURING TWO OR MORE VARIABLES NOT COVERED IN A SINGLE OTHER SUBCLASS; TARIFF METERING APPARATUS; MEASURING OR TESTING NOT OTHERWISE PROVIDED FOR [2020-08]
NOTES

  • This subclass covers :
    • devices for indicating or recording the results of measurements, not peculiar to variables covered by a single other subclass;
    • analogous apparatus but in which the input is not a variable to be measured, e.g. a hand operation;
    • details of measuring instruments, which are of general interest;
    • measurement transducers not adapted solely for the measurement of a single specified variable and not provided for elsewhere, i.e. means for converting the output of a sensing member to another variable where the form or nature of the sensing member does not constrain the means for converting;
    • measuring or testing not otherwise provided for.
  • Attention is drawn to the Notes following the title of class G01.
WARNING

  • In this subclass non-limiting references (in the sense of paragraph 39 of the Guide to the IPC) may still be displayed in the scheme.
