citations across classes.

Whole (2005) paper that corrects the bias inherent in those measure,

Built initialsize1 table which had each patent and it's size at first fee event and it's grant date.

Also have an excel sheet with the number of patents granted of each size by year

Joined initialsize1 and citation_count to get the number of citations on and by each patent with the size and grant date.
