In this paper, I presented a standard of judgment to be considered including of well-known technologies and wrote the considerations on software appraisal. The well-known technologies are generally used to prove a invalidity in the patents. However, it is difficult to ignore their creativity or technical contributions in software programming, since the well-known technologies are not recognized as the advances in the patents. Therefore, I clearly wrote the concepts of well-known technologies in the patents, and suggested the standards of the similarity of software programming when they are found to be well known technologies in the copyrights. I also presented some examples to considered the similarities if the well-known technologies are included. Furthermore, I have been suggested the considerations for determining copyright infringement.
