How to Use UDRP.Tools

This section is designed to help our users understand and use our data better. It will explain how everything on UDRP.Tools works.

If you're looking for detailed information about our data, please check our Notes on Data.

Understanding Search Limits

Guest users receive five free searches per day. Registering for the site will give you a one-time bonus of 50 search credits to use whenever you want. Registered users also have the option to purchase additional search credits. Your search credits never expire and are only used when you have used up all your free daily searches.

The Search Interface (Homepage)

The homepage (Search) is the main interface our users see. There are two primary components to the search interface: Filter Cases and The Results. The Filter Cases section is on the left side and allows users to filter and search for cases meeting particular criteria. The Results are where the cases matching the criteria are found. The domain, case (link to full case details), date and decision type are returned with all results.

How to Use Search Filters

The Search filters are broken up into three tabs: Text, Parties and Domain. These group different search functionality based on the type of data that will be searched.

Text Filters

  • Keyword Search - This searches the full text of all cases in our database. Keywords must be longer than 3 characters, or they will be grouped together for an exact match. For example 'the domain' will search for "the domain" meaning there must be an exact match of for the phrase "the domain" instead of simply matching both 'the' and 'domain'. 'this domain' would search for any case containing 'this' and 'domain' but not require the words to be together because of the character restriction. Exact matches can be forced by using double quotes around the search term, "this domain" would search only for an exact match of 'this' and 'domain' being next to one another in that order.
  • Date Range - This allows users to select a start and end date that cases must be within. It is optional, left empty, it will search all dates.
  • Preset Date Range - This simply helps you quickly fill out Date Range with popular date ranges such as 'Year to Date', Last 3 Years, etc.
  • Decision - Decisions are the outcome of the case. We have two categories: General and Specific. General groups together similar classifications of outcomes. Specific uses the exact decision type which tends to be venue specific and may have nuances like 'Complaint denied with dissenting opinion'. The full information can be found in the Data section.
  • Dissent - Filters cases that contained a dissenting opinion. Only WIPO publishes dissent information in the decision type.
  • Venue - This lets you filter between the different arbitration courts. WIPO, NAF and CAC the currently supported courts. You can also filter for WIPO+NAF since they are the main players.
  • Respondent Replied - This filters only cases where the respondent replied to the case.
  • Considered RDNH - This filters cases where Reverse Domain Name Hijacking was considered. This only applies to WIPO and NAF cases.
  • Found RDNH - This is cases where Reverse Domain Name Hijacking was found. Check how we determine which cases have found RDNH in the Data section.
  • Citation Search - This uses UDRP.Tools' ID numbers to find cases which cite a particular case. If you click on the case details, grab the UDRP Tools ID from that page to use this feature.
  • Custom Frequency - This generates custom frequency filters below Filter Cases

Parties Filters

  • Panelist - This is a normalized list of all the panelists in our database you can filter by.
  • Co-Panelist - This filter can be used to filter in conjunction with the Panelist filter if you want to find cases where two panelists have ruled together. If used without a Panelist selected, it behaves like a normal single Panelist search.
  • Panel Type - This allows filtering based on single member or three member panels.
  • Complainant - This searches for the complainant. Please note complainants are not normalized or filtered in any way so you could see multiple spellings, legal names and other variations for the same organization.
  • Complainant Rep - This is the person representing the complainant. Sometimes it shows the company representing the complainant. This field is not normalized.
  • Complainant Country - Selects which country the complainant is filing from.
  • Respondent - This searches for the Respondent. Please note Respondents are not normalized or filtered in any way so you could see multiple spellings, legal names and other variations for the same organization.
  • Respondent Rep - This is the person representing the Respondent. Sometimes it shows the company representing the Respondent. This field is not normalized.
  • Respondent Country - Selects which country the Respondent is filing from.

Domain Filters

  • Keyword - This keyword search only searches for the keyword in the domain. Please note multiple domains might be involved in a case and we only show the first domain in the search view. If a case shows up that doesn't match your keyword, another domain involved in the same case should match your keyword.
  • Extension - Filters by the TLD of the domain.
  • Pattern - Advanced search tool where you can search for domains that match a pattern. The acceptable codes are L for letter, N for number, O (letter) for character, C for consonant, V for vowel and any lower case letter will search for that specific letter. For example, LLL would return all 3 letter domains. LLx would return all three letter domains that end with the letter x (eg. CVCV would return all domains matching the consonant, vowel, consonant, vowel pattern (eg.
  • Registrar - Searches for which registrar the domain is registered at. This field is not normalized and may have multiple variations for the same company.
  • Exclude Hyphens - Don't show hyphenated domains in the search results.
  • Exclude Numbers - Don't show numeric domains in the search results.
  • Include ccTLDs - ccTLDs are excluded by default since they often have different rules. If you want to include ccTLD cases in your searches, check this box.

How to Use Search Frequency (Below Filter Cases)

This section shows frequency tables about Panelists and Decisions. Custom Frequency information also appears here if selected. These results are all clickable and filter for the selection clicked and is automatically added to the current search.

There are also two clickable Reports. Show Citations Report, which shows which are the most popular cited cases for the current search. Show Outcomes Report by Panelist which is a visual representation of the distribution of decisions of the top 25 most frequent panelists in the current search.

How to Research a Panelist

Panelist Research homepage is a simple page to find a panelist. All panelists in our database are listed and searchable.

Panelist Profiles

Panelist profiles allow you to see a breakdown of the decisions of any panelist and do some basic filtering based on venue, including ccTLDs, and date range.

The report shows solo results, where the panelist was the sole panelist, and group results, where the panelist was a member of a three party panel. Our data is broken down by decision types and decision types by year for both solo and group results.

The Panelists Served With information lets you see how a panelist has interacted with other panelists in group situations based on decision outcomes.

Citations Used shows which cases the panelist most frequently cites in their decisions in both solo and group situations.

How to Use Case Citations

Citations are used throughout UDRP Tools. They can be found on specific cases, panelist profiles and special citation related pages. The special citation related pages are:

  • Most Frequently Citations - Find how many times each case is cited in descending order.
  • Self Cited Cases - This shows cases where the panelist cites a case that they themselves were involved with the decision.
  • Self Citing Panelists - This slow query shows which panelists cite their own cases most frequently including the percentage of citations that are their own cases.

How to Research Cases

Every case has a page that displays the information we have collected from the source. All data is collected from the respective venue. Some fields are normalized to a certain standard.

Some cases may have additional meta information:

  • Cited Cases - Cases mentioned in the case.
  • Panelists Citing - Panelists who most frequently cite this case
  • Cases Citing - Latest (max 25) cases that cite this case. Full search can be done with case number on main search interface using the Citation search.
