    1. Vol 1 Selling a Kit — What Changes the Day a Light Gun Is Offered for Sale The owner decisions that make licences and product rules binding, five ways a kit could be sold and which rules each one triggers, the three kinds of rights and the three kinds of rules a seller meets, where the category's other dives already cover each thread, and the findings this dive adds
    2. Vol 2 H&K's Marks and the MP7's Look — What a Kit May Carry, Show and Say The five live US registrations a light-gun kit runs into, read from the USPTO, including an MP7 registration for toy weapons; how trade dress protects a product's shape and where it stops; H&K's record of defending the look of its guns; the licensed-airsoft model; and nominative fair use applied line by line to the copy on a box
    3. Vol 3 Patents and Freedom to Operate — Which Live Patents Sit Close to a Light-Gun Kit How a patent binds a kit seller and why selling parts is no way round it; the patents found round light-gun sensing and recoil, with their claims and estimated expiry dates; Sinden's recoil patent read element by element against the category's own solenoid stage; the Wii Remote family's end; the camera maker's pointing patents; and what to ask a patent attorney before a kit is sold
    4.

    5. Vol 5 The Kit Plan — What to Ship, the Paper in the Box, Warranty and Liability, and Ten Gates Before the First Sale The recommended order of the five routes and why; what a route A box holds and the rule behind each sheet of paper in it; whether the brick ships; warranty disclosure, the mail-order rule and 'Made in USA'; liability, insurance and records; the ten gates before the first kit ships; proposed decision rows; and the questions only the owner can answer
