have a known biological role, as well as processes and methodologies, such as tissue culture protocols or transformation methods. - Patent can be applied for if (in general): an 'invention' is not patented already, if you can demonstrate a significant novel step, and it is 'not obvious' Clearly these have definitions (and interpretations of definitions) attached to them So increasingly, if researchers make any sort of breakthrough they will tend to consider patenting to protect their intellectual property (IP). In other words, they can potentially capture value from exploiting that technology either directly, by exploiting it and preventing others from doing so, or indirectly, by licensing others to allow them to use the technology, perhaps subject to royalty payments. For commercial application, in the very broadest sense, you have to come to a written agreement with the patent holder. If anyone makes the same parent cross combination and selects a 'different' cultivar from the resulting progeny, they would equally be in infringement of the patent rights. 12 / 14
