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.
Review article comes in the form of systematic reviews and literature reviews and are a form of secondary literature. Systematic reviews determine an objective list of criteria, and find all previously published original research papers that meet the criteria. They then compare the results presented in these papers. Literature reviews, by contrast, provide a summary of what the authors believe are the best and most relevant prior publications.
The concept of "review article" is separate from the concept of peer-reviewed literature. It is possible for a review to be peer-reviewed, and it is possible for a review to be non-peer-reviewed.
