Patent MC-20 Micro Scope aka Perceptor. This patent is for the body tube/shoulder cannon and how it was designed to keep it from breaking. (As a kid, mine ended up broken anyway sadly.) Filed 1984-10-11. Invented by Haruki Saito. JPS6167797U

Last but not least, the patent for Vortex was filed on 1985-05-14 as well. Lots of small differences from the final version, like the torso rotating, a different feet transformation, and the tail parts flipping forward in robot mode. Invented by Daishirou Shibukawa. JPS61188794U

The patent filed on 1985-05-14 for Swindle is similar to the final version, except that the connector peg to form Bruticus's arm folds out differently and does not use Swindle's head. He is shown attached to the prototype Combaticon tank torso. Invented by Daishirou Shibukawa. JPS61188795U

Three months after the patent for the early Brawl and Blast Off, patents were filed for the other three Combaticons. The Combaticon leader was originally a tank robot with a completely different transformation. Filed 1985-05-14. Invented by Daishirou Shibukawa. JPS61259688A

A patent for early versions of Blast Off and Brawl was filed 1985-02-16. They look very different from the final versions, including how they transform. The patent shows how Blast Off would peg into Superion's torso. Invented by Kohjin Ohno. JPS61139283U

Here’s the Macross Valkyrie from Fight or Flee. The other Paradronian looks rather startled by his presence! Interestingly neither Valk is the early Jetfire model (no armour) so it isn’t a case of pulling an existing model off the shelf, rather someone was deliberately inserting Macross Easter Eggs!

Patent for a Lamborghini/tank/robot triple changer! The tank mode does not look very convincing, so maybe it's mis-transformed? Filed 1985-01-31. Invented by Kaoru Matsumoto, who later went on to work on Broadside. JPS61127793U
