3.soopat patent search
SooPat's goal is to make patent retrieval civilian, so that you can find the patent you need instantly without becoming a patent retrieval expert! SooPat website was completely free at the beginning, and it mainly relied on its own funds and donations from SOOPAT users in the early stage. Recently, SOOPAT began to try charging service, but ordinary users can still search for domestic patents for free, but many functions are restricted when searching for new world patents. SooPat now implements a fee system, and ordinary users can no longer search for international patents. In addition, there is an upper limit to the number of patents that ordinary users can browse every day.
