How to deal with property disputes?

Party to dispute (Respondent) was inam land holder (got land from Govt.) but they didnot get occupancy rights certificate from government then, thereafter sold to us via registration in 1960s/1070s [sale was registered]. We also didnot apply for occupancy certificate but before the suit we got occupancy certificate but respondent got it cancelled via suit and they got the occupancy certificate. Being a law graduate my law point is that we are in possession for min 12 years if property is pvt. and 30 years if property is govt one [adverse possession contention]. But in this dispute Telangana HC's division bench ruled in favour of respondent. Kindly tell me whether can we file a curative petition or any other to contest the division bench ruling with adverse possession argument. Tell me the proper law in this case and correct me if I am wrong dignitaries. Note: 1. We are only in possession since 1970s. 2. Suit filed by respondents after 2005 only.
