Abstract
Training concerning prior art search of patent documents and the best practice combination of lecture, practical exercises, and discussion improves trainees' search skills, and improves self-efficacy. Taking inventive step into consideration in the early stages of experience, as well as experience, has effected tangible improvements in capabilities to perform prior art searches. In future, it is very important that those involved with intellectual property receive special training, with a particular emphasis on making practitioners aware of such points and techniques in prior art search. Ongoing investigation of efficacy in this filed is urgently required to ensure the efficiency and integrity of the patent system worldwide.
