A computer implemented apparatus for automatically generating and filtering creative proposals is disclosed. Particularly, the computer implemented apparatus automatically generates all possible featured component code sets which corresponding to all possible featured components, and compares them to the prior art code sets which corresponding to the prior objects. Thereby, the novel code sets which corresponding to the novel creative proposals are rapidly filtered out. The computer implemented apparatus comprises a standard component database, a permutation and combination module, a featured component code set database, a prior art code set database, a matching module, a sifting module and an output module.
