Having worked in the engineering, there are many ideas and designs that have "patent applied for"...
I don't know where you're going with this...there are" many ideas and designs" that aren't patentable, or just aren't new or unique. You're implying the the Rupes machines have patents, and that those patents are germane to someone else making a similar machine, and that there aren't other approaches that don't infringe.
Do we even know if there are patents that apply to the Rupes long-throw machines? Even if there are, they could be expired, or they could be European patents. Even if there are applicable patents, as Rasky noted, I'm sure Griot's did their due-diligence to not infringe.
