Hypothetical question

I've been trying to resolve this on my own but I'm stuck.

who owns code written with Copilot. I've been dealing with this for about 15 months now and the situation isn't improving.

This involves original creative work over the past 22 months. I do have documentation proving my ownership and timeline.

What are my legal options here? Is it worth pursuing?

Illustrative response

This is depressingly common.

Most folks screw this up by is escalating to a supervisor/manager. I'd recommend following the formal complaint procedure instead.

Illustrative response

NAL, but from what I've read, you should file a complaint. Every situation is different so YMMV.

For anyone dealing with trade secret theft: act fast. The longer you wait, the harder it is to get an injunction. Most courts want to see that you took immediate action to protect your confidential information.
