I will admit to being an ignoramus WRT patent law Toolmaker51, but how does showing a photo or video of a patented device violate patent rights?

?
Stated "Likely" video provider gave barest glimpses to avert onslaught of patent infringements.
i.e. shorting his opportunity, possibly a patent pending.
That's minimal display of the mechanism, mounting to the body, about any feature assisting another party design, getting a product marketed before the original. A brief intro like the video is 'Kickstarter'/ GoFundMe type fishing for partners or funds.

I'd compare this to my own issues. Within my not small toolroom, envision tying in sensible courses to a select public, igniting interest in the trades. Think I have banners, descriptions and neon all over town before getting the doors open? Any one with more resources could easily ruin this plan.
