Patent myth
“If I invented it independently, nobody else can have it patented.”
Independent invention is common and is not a defence. India is a first-to-file system: the person who filed first prevails, whatever you can prove about when you had the idea.
Simultaneous invention happens constantly, because inventions are usually responses to a problem the whole field is looking at. Your lab notebook proves you invented it. It does not give you a right, and it does not stop the other party enforcing theirs against you.
Teams delay filing because they are confident nobody else is working on it. Somebody usually is.
