Form 3520 limit is 100K per house hold or per person?

I just want to understand form 3520  100K limit is for house hold or each person? i.e. can a family of three get give up to 300K and not fill this form up ? each person 100K
If My dad wants to give us gift less than 200K. 99K my wife, 99K myself. do we need to file 3520?
