What is the duration of filing charge sheet in 380/406 and it act 66

My ex company name xyz where we have worked so, company xyz registered complaint against me and two of my friends, regarding Software leakage & Client re-direction for their own benefits & which has created financial loss of the company, under section u/s 380, 406 IPC and 66 IT act on 20th Aug 2015. But police filed a FIR on 10 Feb, 2016 for that complaint. It almost 2 months of filling FIR against us. But Police didn't file any Charge sheet yet. We have filled anticipatory to session court but Magistrate dismissed our anticipatory, coz IO tell to magistrate "we are investing". Our company director give bribe to police for assault me and my friends. I am asking how much time to file charge sheet and how much time to take by police for investigation, coz it almost 8 months to complaint and 2 months for FIR. Can you suggest me how can we come out from this case ?
