Where:

  • there is only one option the person skilled in the art would consider in solving either the identified problem or any subsequent practical difficulty;

  • that option would at once suggest itself to the person skilled in the art, e.g. the option is part of the common general knowledge;

  • there is no practical difficulty in implementing that option; and

  • neither the prior art, nor the common general knowledge, teaches away from the solution;

then an inventive step objection will apply.
