lapse_of_patent field missing?
Hello,
The us_term_of_grant file appears to be missing all data on the field "lapse_of_patent". For example, all lines in the us_term_of_grant.tsv file have no values for "lapse_of_patent".
'"uuid"\t"patent_id"\t"lapse_of_patent"\t"disclaimer_date"\t"term_disclaimer"\t"term_grant"\t"term_extension"',
'"0000hq4800wcm85ghvyz34mbe"\t"D657425"\t""\t""\t""\t"14"\t""',
'"00013ul6gy7ydcy6qi9f4sib4"\t"10323501"\t""\t""\t""\t""\t"1266"',
Is this a data error?
Thank you,
Chris
