Applicant

An applicant is a person or organisation (e.g. company, university, etc.) who/which has filed a patent application. There may be more than one applicant per application. The applicant may also be the inventor, although this is not necessarily the case.


The applicant format for a person is made up of the surname followed by the first name(s) (e.g. Smith John).

You can search for one or more words (up to a maximum of four). If you enter more than one word, only those documents will be retrieved in which all the words appear (e.g. Smith John). You do not need to type AND as it is the default operator.

The first name(s) of an applicant may often be abbreviated (e.g. Smith J.). In order to retrieve patent documents, please enter smith j for example.


The applicant format for an organisation is made up of all the words comprising the name of that organisation (e.g. British Aerospace).

You can search for one word (e.g. Aerospace) or more (up to a maximum of four).

If you enter more than one word, only those documents will be retrieved in which all the words appear (e.g. British Aerospace). You do not need to type AND as it is the default operator.


Using quotation marks (e.g. "British Aerospace" or "Smith John") will retrieve only those documents in which the exact phrase is present.

You can also use the NOT operator to exclude some words from your search query.


Apostrophes, slashes and hyphens cannot be used. Please use blanks (spaces) instead.


A patent may have been sold to another company. In the database, it is the name of the patent-holder at the date of filing which is registered, so it can be difficult to get accurate information about new patent-holders from patent databases. However, for EP and Euro-PCT documents, you can refer to the online service Register Plus (www.epoline.org).


A search with a US number of the grant will retrieve the corresponding application. A search with the assignee of the B grant will also retrieve the corresponding application (even though this has no assignee/applicant).


Note: Approximately 38.9 million documents contain the name of the applicant(s). In the case of documents published in other alphabets (Cyrillic, Greek), neither the name of the applicant nor of the inventor are searchable.


If you do not know whether the person is the applicant or the inventor, please use the Quick Search mask.
