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.

Search Limits

Unregistered users have a quota of five searches per day.

Registering an account on the site is free. Registering on the site creates an account with 50 non-expiring search credits. These are available whenever the daily allocation of five searches is exceeded.

Registered users are able to purchase additional blocks of non-expiring search credits.

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.

Search Filters

Search filters are grouped 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 - performs a full text search of all cases in the database. Advanced search features are described below.
  • Date Range - This allows users to select decisions issued only within a certain date range.
  • Preset Date Range - Provides a variety of pre-configured date ranges such as 'Year to Date', ‘Last 3 Years’, etc.
  • Decision - enables filtering according to the outcome of the dispute. General outcomes are: Granted, Denied and Split. The Specific outcomes enable filtering on a specific outcome type. These specific outcomes use the exact language used to describe the outcome by the UDRP provider and are often venue specific. There are many permutations to the specific outcomes such as 'Complaint denied with dissenting opinion’, or ‘Transfer, cancellation in part’. The Notes on Data page indicates how Specific Outcomes are assigned to the General Outcomes categories.
  • Dissent - Enables filtering on whether or not a decision includes a dissenting opinion. Only dissents as to whether a complaint should be accepted or denied are identified as such. Dissents as to RDNH or as to specific findings are not classified as dissenting opinions for the purpose of this filter. WIPO publishes dissent information in the decision type. Most of the other decisions with a dissenting opinion are manually identified.
  • Venue - Enables filtering by UDRP provider. WIPO, Forum, CAC and CIIDRC are the currently supported venues. At the moment, only summary information is available for CIIDRC decisions, not the ability to do a full text search of CIIDRC decisions.
  • Respondent Replied - This filters only cases where the respondent replied to the case. This is of questionable accuracy and should not be considered that reliable
  • Considered RDNH - Identifies decisions where the Panel considered making a finding of RDNH, whether or not an RDNH finding was made.
  • Found RDNH - This enables filtering on whether or not the panel made a finding of Reverse Domain Name Hijacking. is used as the source.
  • Citation Search - This enables users to identify decisions that cite a specific dispute. To use this feature obtain the ID number for the cited case. The ID number for a particular dispute is found on the dispute details page for that dispute. The details page is accessed by clicking on the outcome of the dispute when the dispute appears in the search results.
  • Custom Frequency - This enables the user to generate frequency tables on a number of different variables.

Parties Filters

  • Panelist - Panelist names are normalized to remove variations.
  • Co-Panelist - This filter can be used to filter in conjunction with the Panelist filter to find cases where two panelists have served together on a Panel. 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. Complainant names are not normalized so there could be multiple spellings, legal names or 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. It is not populated within the database for many decisions.
  • Complainant Country - Selects the country where the complainant is located. Not always populated in the database.
  • Respondent - This searches for the Respondent. Respondent names are not normalized so there could be 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. This field is not always populated in the database.
  • Respondent Country - Selects the country where the Respondent is located. Not always populated in the database.

Domain Filters

  • Keyword - Searches for the appearance of the keyword within a disputed domain name. Please note multiple domains might be involved in a case and that only one is shown on the search results page. Where the dispute involves multiple domain names, all the disputed domain names will be checked for a match to the search keyword. It is possible that the domain name appearing in the search results does not match the keyword search, but that the keyword is matching on one of the other domain names involved in the dispute.
  • Extension - Filters by the TLD of the domain.
  • Pattern - Advanced search tool enabling identification of disputed domain names that match a certain 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 always populated and 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.

How to Use Keyword Search

Keyword Search - Entering the keyword will find decisions in which the keyword appears.

Example: BLUE

Multiple Keyword Search - Searching on multiple keywords will only return decisions in which all the keywords appear somewhere in the decision.

Example: BLUE RED

Exact Match Search - Entering a phrase in quotes, will return only those decisions where that phrase appears.

Example: "BLUE RED"

Exclude Keyword Search - Use the minus sign - to exclude keywords.

Example: BLUE -RED - This search would include blue but exclude results with the keyword red.

Example 2: +BLUE -RED - This search is functionally identical. You can tell the search to require a keyword with the + symbol.

Wildcard Search - Use * to perform wildcard searches.

Example: IDENT*

This will return decisions that contain the words IDENTITY, IDENTICAL, IDENTIFY, etc.

Wildcards do not work with "exact match" searches, but can be used in combination with them.

Example (invalid): "is confus*" - This won't work

Example (valid): "domain is" confus* - This will match anything with "domain is" and any string starting with confus

Proximity Search - Proximity searches enable you to search for one keyword within a certain number of words of a second keyword.

To search for two words appearing within a certain number of words of each other in any order: word1~number~word2

For example, researching how panelists treat late filed responses is a task for which proximity search may be helpful. Without a proximity search, it could be difficult to identify those cases. Many such cases would not include the exact match phrase "late response", while doing a broad search for the words "late" and "response" appearing anywhere in the decision would result in too many false positives.

A proximity search for decisions where the word "late" appears within five words of the word "response" would successfully locate permutations such as "response was late", "late filed response" and "response was filed one day late".

To perform this search, enter: late~5~response.

Ignored words and punctuation

Some words, such as “the”, “in”, etc. are ignored. These are called “stop words”. A full list of stop words is below

One, two and three letter words are also ignored.

For example, a search on the exact phrase “be the best”, will be treated as a keyword search on “best”

Punctuation, such as commas and periods are ignored

Capitalization does not matter

Deep Search

Deep Search is available to logged in users. If Deep Search is selected, the exact text entered into the search box will be matched against the raw text of the decision. There are no stop words in Deep Search.

For instance, if you wish to search on the phrase “this is what”, it will not work in the regular search since THIS, IS and WHAT are all stopwords.

By selecting the Deep Search option and entering THIS IS WHAT in the keyword search box, will return decisions that include the exact phrase “THIS IS WHAT” in the decision text.

Deep Search is much slower than regular search.

Filter Tags

Filter tags appear in little “pills” above the search results. Filter tags are helpful to confirm the terms used to refine the search. You can also click on a pill to remove that filter from the search results.

For instance, if a search is performed using the conditions:

  • Keyword = best
  • Outcome = Denied
  • Venue = CAC
  • Ruleset = UDRP

The Filter Tags will look as follows:

If you want to remove the requirement that only Denied decisions appear in the results, just click on the button. This will eliminate that filter and will automatically rerun the search, displaying the search results for a search with the conditions:

  • Keyword = best
  • Venue = CAC
  • Ruleset = UDRP

As follows-

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.
