Interpretation of IPCR results
Posted: Thu Feb 16, 2017 3:26 pm
When accessing IPCR of a specific patent through OPS, I find for example such a kind of result
IPCR: G01V 15/ 00 (G01V 15/ 00 A I); G07C 9/ 00 (G07C 9/ 00 A I); H04M 11/ 04 (H04M 11/ 04 A I)
Hence, using this as a practical example, my question is:
a) which is /are the core invention class(es)
b) which is /are the advanced invention class(es)
c) which is /are the core additional class(es)
d) which is /are the advanced additional class (es)
My guess is that these classifications are related to the parenthesis and to the A I annotation.
Thank you and best regards
