This feature allows you to directly select the technology to which the efficacy topic is referring, allowing you to further customize your filters. This option has been added because it provides more options to specify a search based on technology and its effect. This filter works through PatSnap's AI technology that uses patent text data to train the model. Through this model, patent data is extracted and processed, and the 'Efficacy Topic" that can accurately describe the direction of the patent optimization is obtained. Please note that this field only supports the screening of Chinese patents for the time being.
To use this filter, you can click on "more" or the "Efficacy relation phrase" to open up the "Efficacy Theme Selection Panel". after selecting a topic from the left side of the popup, the efficacy phrase of this topic will be shown on the right side. You are then able to select the phrases of interest after which the patents that meet the conditions will be displayed on the search result page.
