Legal Question in Business Law in Massachusetts

Quite legal, and unsurprising if one thinks through the issue. Unsolicited idea submissions are prickly things. Disney took one and lost a nasty case concerning a concept for some golf course, if I remember rightly. The only defense for big companies against claims by submitters (whose ideas might already be under independent development within the company) is to institute this kind of blanket policy. Then, of course, the question for an inventor wishing to present to the big company (here, Apple) is how to evoke an interest in the idea without giving away the chance of remuneration. The inventor has to present enough to whet the appetite but keep the key trade secrets undisclosed until an agreement different from the blanket terms can be reached. This is different if the inventor has a patent, of course, as the blanket submission terms would not be read to be a conveyance of the patent without consideration.
