IPC PATENT EVALUATION METHOD AND SYSTEM USING WEIGHED AVERAGE OF REGISTRATION RATIO BASED ON IPC CODESProvided is a patent value evaluation method applying a weighted average value of a patent registration ratio for each IPC code, which comprises the steps of: (A) multiplying a present value by ...
The present study uses Dice coefficient as measure to quantify similarities between parent patent and forward citations it receives, based on International Patent Classification codes (IPCs). IPC codes are a hierarchical way of assigning the category to which every patent belongs, and may thus be ...
This report describes our comparative analysis of MeSH and the main patent classification system, the International Patent Classification (IPC). We investigate the hierarchical structures as well as the properties of the terms/classes respectively, and we compare the assignment of IPC codes to patents...

Some of the existing codes and the three classifications ensure adherence to the allowed number of defects and severity in a PCB product. The lowest PCB quality level, class 1, has a significant acceptance rate of defective aspects. However, Class 3 PCB products have a very low tolerance to ...
(FIG. 10). Thus the most significant 5 bits in the 24 bit word, after the control information, represent, in run-length coded form, the first black section of the pattern to be reproduced. The 5 bit codes are fed in parallel, in order of significance, to the counter RC where they ...
