How to do a basic search
To search this database, you need to enter various search criteria (a word or string of characters) in the search text fields and select a field, a type of mark, a status and in some cases actions for a given time frame.
You can also combine several search criteria using "Boolean" operators (OR, AND, NOT). For more flexibility, your query can also include wildcards like an asterisk (*) for a string of characters or an interrogation mark (?) for a single character.
The searching algorithm uses "Boolean" logic and ranks results based on the hit count or the number of times individual words or search criteria appear in the selected field(s).
Select search field
Twenty one (21) fields are made available for searching. Each of the fields corresponds to a specific element of information on the trademark.
The field to be queried depends on the type of information that you are looking for and your search criteria. See the section entitled Searchable fields.
When searching for a trademark name, it is recommended that you search against the field "trademark lookup", which searches trademark title, trademark description, foreign character translation, foreign character transliteration, index heading and GI translation.
Enter search text
Enter your search criteria (a full word, a word stem, string of characters, numbers, special characters, or combination thereof, using a multiple character wildcard or a single character wildcard in the search text field).
The search engine is case and accent insensitive, meaning that upper- and lower-case letters have no bearing on the search results, nor do accents. Generally, trademarks which consist of words only are all written in capital letters.
