Abstract: A facility for providing a registrability analysis for a user-provided potential trademark is described. The facility receives a proposed trademark and proposed goods and/or services from the user. The facility then applies a series of comparisons and analyses to determine which trademark applications or trademark registrations in a given trademark registry may pose registration risks, weights those risks according to a relative weighting model, and obtains an overall risk analysis for the proposed mark and goods and/or services. The facility reports the risk analysis and relevant results for the proposed mark and goods and/or services.
