In general, there probably isn't an issue. However, it is very important that you understand anything you sign. In IP assignments the thing I am most careful about is the indemnification clause or clauses. It is fairly boilerplate to include language that says "you assert that you have the right to sign off this IP, and if someone later challenges that right you will indemnify they buyer against any infringement action brought against them."

That is what is think of as an "open ended" indemnification which is to say, you sign this over, then later someone sues them for patent infringement. Even though you had no idea somebody had patented the idea, you might be on the hook to pay the legal costs or licensing fees to make the buyer whole again.

So make sure the document doesn't say indemnify anywhere :-) And as others have said consider having a lawyer look at it.
