Dear SO/AC leaders, To follow up on our previous message sent prior to ICANN 55, we wanted to thank all those who reached out and met with the Trademark Clearinghouse (TMCH) Independent Review Team to provide input on this study. We are continuing with outreach and stakeholder discussions, and as part of this work, Analysis Group has developed a questionnaire to assess the opinions of various groups that interact with either all or some of the TMCH services. Given that feedback from interested stakeholders is extremely valuable to this review, we would greatly appreciate your assistance in helping us promote the TMCH questionnaire. Therefore, it would be fantastic if you could share the following link (http://www.analysisgroup.com/icann-trademark-clearinghouse/) via one or more of your communication channels (website, blog, e-mail, bulletin board, newsletter etc.) and encourage your members to complete the questionnaire. As noted previously, ICANN is conducting an independent review of the TMCH, which was recommended by the Governmental Advisory Committee (GAC) in 2011 (see https://archive.icann.org/en/topics/new-gtlds/gac-comments-new-gtlds-26may11...). The purpose of this study is to assess the effectiveness of the TMCH in combination with the areas that the Governmental Advisory Committee (GAC) specified for review, which include: (1) handling of non-exact matches to trademarks, (2) extension of the Trademark Claims notifications, and (3) impacts of the Claims services on the commercial watch services market. This is intended as an informational study to support discussions on related Right Protection Mechanisms (RPMs) activities, such as the work of the Competition, Consumer Trust, and Consumer Choice Review Team (CCT-RT) and the Generic Names Supporting Organization (GNSO) review of all RPMs in all gTLDs Policy Development Process (PDP). Thank you again for taking the time to consider our request, and please let us know if you have any questions that we can help address.
