A patent is essentially a limited monopoly whereby the patent holder is granted the exclusive right to make, use, and sell the patented innovation for a limited period of time. The five primary requirements for patentability are: (1) patentable subject matter, (2) utility, (3) novelty, (4) nonobviousness, and (5) enablement. The Patent Law Treaty (PLT) aims at harmonizing national patent formalities throughout the world. It is designed to streamline and harmonize formal requirements set by national or regional Patent Offices with respect to the filing of national or regional patent applications and the maintenance of patents and certain additional requirements related to patents or patent applications, for example, communications, representation or recordation of changes concerning patents and patent applications. According to an impact assessment, the implementation of the PLT was considered to have positive impacts on users, particularly in terms of simplification of procedures.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
