Hasbro has the master toy license for Marvel and Star wars. It does not include certain things. Building block lines/construction toy is an outside those master rights thing. Lego has those currently. It also doesn't cover certain other things too, like certain kinds of collectibles that fall under other kinds of banners. Bobbleheads for example are exempt, as are other statues types and various other material. And the Master toy license aspect is also only for certain markets. Usually American continent, Europe, and select areas of Asian markets and sometimes China. Hot Toys is kind of a grey area because they are technically made in Japan which is a different rights system and sold stateside as "imports" through Sideshow, and are also considered more like a 'direct' market premium good. It's similar to how DC Direct handles DC stuff for the specialty market, but Mattel has the master toy license for DC material outside of construction toys which Lego has. On contracts that have to do with Master Toy license, it can vary and is usually entirely contract based. In theory, though not often in practice, you can write a master toy license contract that excludes or includes whatever and sell that excess you excluded from it to someplace else. As the master rights holder to determine the master toy license, you can word that contract any way you want so long as the company signing it/purchasing it agrees. That's usually a negotiations phase before purchase. Same is true for likeness rights agreements. You can work in any kind of stipulation you want so long as the company agrees that's purchasing it and is willing to sign it. So if VW or any car company said "Cannot ever hold any kind of firearm" and Hasbro wanted those vehicle rights to use for their figures, they'd have to agree and not include any kind of firearm element. It's entirely contract based and how it's worded or stipulations attached. Direct cars fall under likeness rights parameters iirc. Sometimes that can include scales, but sometimes that means toy types. Like Hasbro can do a legends scale sideswipe fine and accurate, but not a die-cast car. So they can do a 1:64th scale if it's considered an action figure and transforms. They can't do a "hot wheels" styled metal or plastic car though of that car since Mattel directly has those toy rights. Action figures fall under the same parameters as "Dolls". (This is what Transformers fall under since they are predominately variable action figures. But Hasbro owns the entirety of the brand, so they themselves decide those contracts of any material outside of their own company. Unless it pertains to needing to obtain outside likeness rights like real world cars.) Normal cars fall under something else. Stuffed animals iirc, fall under something else entirely too. And it can vary from there based on contracts. Model kits usually also fall under something else entirely as well. And stuff like Lego is considered "construction toy" rights. Same to Mega Construx. Same to K'Nex and Steel Tec. Like Playmates owns the master toy license for TMNT, but not the construction toy rights(Mega Construx owns that). They can make figures and any kind of vehicles they choose in any scale, including die-cast cars type of show vehicles that aren't real world vehicles but they cannot include building block pieces of any kind or anything else that constitutes a "construction toy". Though there are some grey areas of "conveniently uses a similar size of clip" that can often slide through. But cannot directly use brick peg style construction in an obvious manner. So it's usually by toy types. And how that's considered separate. Not usually by scales. But it can vary contract to contract, because a company can word the contract any way they deem fit that another agrees to. It also can go farther too. Like Bandai of America has the master license for Teen Titans animated/ TTG. But that does not include comic material. Which is firmly at Mattel. Same to Young Justice. BoA only has the DC license for that one CN show and those tied to it. They also do not have the construction toy rights. So contracts can also be determined by what's considered a separate entity too. This is also how Lego can make large figures of Star Wars and Marvel. They are considered construction toys in what they interact with and are made of. But that can also be expanded if they choose so long as it interacts with construction toy blocks directly and obviously. Same as how Hasbro could do Mashers, which were heroes you built, but were considered action figures that could swap parts. Not brick built or a construction toy, so it didn't tread on the construction toy rights.
