Companies will always try to scare you after you quit if they can, as a way to enforce their “intellectual property”

A former company that I worked at sent me a legal threat after I left, I had told some other engineers which company I was going to and a few decided to check it out and apply too. The company I was leaving accused me of illegally poaching their employees.

Thing is the company has the burden of proof if they want to show that I damaged them somehow. And IANAL but I think the same would apply here. They have to show that this has damaged them somehow to go after you.

If you got laid off with a severance package of some sort they might try to go after that. They may have made you sign some sort of exit paperwork. Even that though would be pretty epically petty.

But I’m not a lawyer, you might want to sit down and consult with a lawyer before you meet with them. I wouldn’t sign anything they give you in that meeting, “I need to have my lawyer review this first” is something I say to people when they want to pressure me to sign things. It’s pretty hard to argue against that, it’s a very reasonable thing and demanding you sign something you’ve just been given without having a lawyer look it over is unreasonable.

Also if you don’t work for them you don’t have to meet with them, you definitely don’t have to meet them on their terms. You can tell them you are happy to discuss with at your lawyers office. Good luck, lawyers aren’t super cheap, but they are worth every penny in protecting your rights.
