The Advanced Search Form is divided into four tabs, each geared towards performing a different type of search. These tabs are explained in detail below.
The Boolean Search form makes it possible to enter multiple keywords linked together with Boolean terms AND, OR, or NOT, with each term searchable across all fields or only a particular data field. By default, only one field is displayed, however more can be added by clicking one of the plus signs that appear to the right of each field. Conversely, unneeded fields can be removed by clicking on the adjacent minus sign. There is a maximum limit of eighteen (18) fields in the search form. The available data fields to search change dynamically depending on which database is selected from the dropdown "Options" menu at the bottom of the form. Only one authority database may be searched at a time when performing a Boolean Search. The following screenshot depicts the Boolean Search form.
The Number Search provides the user with a form for entering one or more publication numbers and searching them across one or more patenting authority databases within PatentAnalysis.com. Users can select any combination of the eight available databases to search across. The quantity of publication numbers that are entered appears to be unlimited. Document numbers are entered with no punctuation. If patent numbers are entered with commas, for example, the search will not return any results. When more than one database is searched, results are returned in a list broken down by database. If no results are found in a particular database, then that database won't be listed. The screenshot below shows the Patent Number Search Form.
The Form Search provides a variety of data field specific query entry fields along with a "Full text search" field for entering search keywords. Only one authority database may be searched at a time when performing a Form Search, and this is selectable from a dropdown menu at the bottom of the form. The form changes dynamically depending on which authority is selected to search. The screenshot below shows the Form Search.
PatentAnalysis.com offers a Chemical Search function that uses SMILES (Simplified Molecular Input Line Entry Specification) to allow users to search the database for chemical structures. There are two ways that a SMILES query can be entered: by entering the search string directly into the text box, or by drawing the chemical structure using the MarvinSketch structure drawing tool that is built into the PatentAnalysis.com interface.
When using the Chemical Search form, drawn structures must be converted into text SMILES queries before the query is submitted. Structures entered in SMILES format may also be converted into a drawn representation by clicking on the small, leftward pointing arrow button below the text field.
The user has four options available from the "Search using:" dropdown menu. Chemical structures may be searched by similarity score, or by substructure. When searching by similarity, users can specify a score of greater than or equal to 0.8 or 0.95. Likewise, when searching by substructure, users can choose to limit results to those with a score greater than or equal to 0.5 or 0.8. These scores represent how closely a result chemical structure must match the query structure.in order to be returned. See the MarvinSketch article for further details.
The Number Search, Quick Search, and Chemical Search are the only search forms on PatentAnalysis.com that enable the user to search multiple authorities simultaneously. The Boolean Search and Form Search only allow users to search one authority database at a time. It is somewhat unfortunate that PatentAnalysis.com does not give the user the option to search across multiple databases with all search forms.
