Software Patent — prior art search before patent filing

I'm dealing with a situation and need some guidance.

prior art search before patent filing. I've been dealing with this for about 16 weeks now and teh situation isn't improving.

I have already done some research online but the other party is not cooperating.

Has anyone been through something similar? What worked for you?

Have you tried reaching out to your state's legal aid society? They sometimes have free resources or mediation services haha.
