I am trying to compute the generality index of each patent.
to set the sample of patent,
1) I only focus on Ipr_type='PI'.
2) only include the earliest success patent for each docdb_famliy_id.
According to this, when I am computing the generality index of these patents, should I exclude the cited appln_ID which not satisfy the above setting? Or the cited appln_id does not need to meet the standards for setting the sample of patent?
Thanks in advance.
