In my opinion it's only acceptable for software written during your employment directly relating to your work there. And even then it should have been in your employment contract.

Don't resign, let them fire you. They're in the wrong here. Don't do their dirty work for them.

They included the vague and ill defined "or anticipated".

It's a bad contract and shouldn't hold up in court (if the court was reasonable), even if you weren't being pressured to sign under duress.

It's certainly not standard and I would never sign something like this.

Any way, they can ask. Asking, though, might be a red flag. After all if you leave their employment they will not give you back your copyright.

i'd talk to a lawyer but from my experience, no they can't. the purpose of enumerating prior art is exactly so they *can't* claim ownership of your prior work and you can't claim ownership of work you do for them once you're working for them.

lawyers love to put things in contracts that are blatant overreach in the hopes you'll just sign it. they are used to redlines to cut out such stuff too.

Could agree to give them a perpetual non-exclusive license to the code and print them off a copy of the GPL (or BSD license or whatever)

Pretty sure a tabletop RPG management app doesn't related to your employment...

But my response would be "Well then run it through legal because I'm not signing it over."

The whole thing is bullshit, since when does an employer have a right to ANYTHING that took place before employment?

Tell them to fuck off and find a new job.

It's our job to say no.

I have had many high-level jobs and always negotiated my IP agreements.
