Quoted from rubberducks:
It's a canted extending arm attached to a box at each end. The contents of either box has no bearing on the arm, nor the arm on them. There is absolutely NOTHING novel about it.
Secondly, it hasn't been tested in court. You can get granted a patent for virtually anything in the US if you're prepared to file ... see JPop's list of crap. Doesn't mean you'll be able to defend any of them.
Or you don't understand what the criteria really is...
There is certainly enough there to make it novel... A patent doesn't have to use all new undiscovered tech to be novel.. It can be a new use of existing concepts in new novel applications. You may think using a arm is 'obvious', but have you dug into the actual meat of the patent?
You may think this is 'obvious'... but so would a folding backbox right? Yet Wico was able to patent a folding backbox in 1985... years after Bally and others were already doing a folding backboxes... because their patent was about the hinge design to address what they identify as shortcomings with prior folding backbox designs.
Or how about Stern patenting the idea of using LEDs for GI lighting? Yup... they did that.
The deeproot patent covers lots of concepts such as the rotating PF, how they are doing the backbox folding, the different service positions, the mounting, etc.
And while you may point the finger at the US patent process... note deeproot has filed with WIPO - not just the US.
I have lots of problems with this concept.. and patents in general... but simply pointing at it and saying "its just an arm..." is not one of them.
