Enter a list of company names or patent numbers to retrieve patents in summary of application year, country, legal status, family and quality/ value etc. How do you know if the assignee's patents are active, pending or expired? Are they strong in quality and value? If they are, particularly in what markets would you like to know? To answer the above interesting questions, the Patent Listing data provides you with a detailed list of the patent portfolios with info you need, ranging from application year, to country, to legal status, to quality and value to name a few parameters. How do we do that? We include decades’ worth of global full-text databases, such as the US, China, EM/EUIPO, Japan, Korea, WIPO and so on, and keep them updated on a timely basis—as frequently as every day or week, depending on the sources. Furthermore, the data downloaded are cleansed to minimize data errors and thus search and analysis errors. For example, we standardize assignee names to enables individual patents to correspond to a single owner; logic-based corrections ensure that values are corrected based on rules. In addition, we use advanced algorithms in analyzing, selecting, and presenting the most current and accurate information from multiple available data sources. For instance, a single patent’s legal status is triangulated across different patent data for accuracy. Moreover, proprietary Quality and Value rankings put patents that are applied in the same Patent Trademark Office under equally evaluative criteria, offering subjective predictions for the patent's likelihood of validity and monetization.
