Abstract: The basic concepts of a patent information retrieval system are outlined and the basic features of a new system called the model of stratificational structure (MMS) are described. It comprises a general subject classification schedule having eight sections, A-H, similar to the IPC sections and a categorical subject classification schedule with sections M S and U covering, respectively, method or process, structure or function and use or action. The system is thus a type of hybrid system in which subjects of invention are classified on the first schedule and details of method, structure or use are indexed on the second schedule. The advantages of such a system over the IPC are discussed along with suggestions as to how it could be used to provide an improved IPC.
