To the first paragraph of Rule 2.4.4, add:-

Any game object produced by a business action is considered to be an item of Stock, and such items are added to the producing Corporation’s Stock upon creation.

Replace “As a business action, a Production Corporation may produce one unit of Product.”, with:-

As a business action, a Production Corporation may produce one unit of Product, prefixed by any one-word adjective, unless that Corporation already owns a unit of Product prefixed by a different one-word adjective.

And add an action:-

As a business action, a Science Corporation may change the adjective on any one unit of Product in their Stock.

A Leader of a Production Corporation may include the phrase “We unveil our new ‘XXX’ range” in comments to this post, where “XXX” is any one-word adjective. If any Corporations own any units of Product when this proposal enacts, the Product belonging to that Corporation shall be given the most recent adjective specified by the Leader of that Corporation, as per the previous sentence of this proposal. If no such adjective was specified for a Product, it shall take the adjective “Generic”.
