Aspects of daily life
Industrial property rights can ensure that third persons cannot adopt your idea as their own and realize it before you have done so. You can protect an invention in a technical field for example by filing a patent for it. More detailed information can be found in the aspects of daily life "Patents, Brands, Transfer of Ideas" (Patente, Marken, Ideentransfer).
