I think you have exactly the right attitude, Linda. You aren't scared off simply because someone has waved a patent in your face and claimed that you are violating it. Let MOE go to the costly expense of trying to prove that you have infringed upon their patent -- this is a pretty difficult legal standard to prove and the burden is on MOE to do so. Even if MOE wins, they can only get an injunction (that you are ordered to stop making the infringing product) and damages (which are difficult to prove, and include things like lost profits, which only accrue once the patent is public, i.e. from today on).
People who own patents sometimes use them to force others into buying licenses from them, by threatening them with legal action if you don't. I hope none of the pocket making WAHM's give into these threats (unless they are truly coping FB).
