  • While viewing your search results:
    • To modify a search, click on your browser's "Back" button to return to the search screen.

Basic Search

The Basic Search screen is composed of one main search box and a few search limiters. The user can enter their search in the "Search Query" box.

The first method of limiting the search is to use the drop-down list to the right of the "Search Query" box. The user may select one of three options:

  • All of the words - This option will retrieve records that contain all of the words the user has entered in the "Search Query" box. This option uses the Boolean operator "AND."
  • Any of these words - This option will retrieve records that contain any of the words the user has entered in the "Search Query" box. This option uses the Boolean operator "OR."
  • Exact phrase only - This option will retrieve records that contain the exact phrase the user has entered in the "Search Query" box. This option uses the Boolean operator "ADJ." (Note: placing quotes around a name (e.g. "American Medical Association") or a term (e.g. "HIV infection") is the same as selecting the "Exact phrase only" operator.)
The second method of limiting the search is to use the "In:" drop-down list immediately below the "Search Query" box. The user may select "all fields" or one of the following fields:

  • Title
  • Abstract
  • Issue/Publication Date
  • Patent/Application Number
  • Application Date
  • Application Serial Number
  • Assignee Name, City, State, or Country
  • International Classification
  • Current US Classification
  • Primary Examiner
  • Assistant Examiner
  • Inventor Name, City, State, or Country
  • Government Interest
  • Attorney or Agent
  • PCT Information
  • Publication Document Kind Code(s)
  • Foreign Priority
  • Reissue Data
  • Related US App. Data
  • Referenced By
  • Foreign References
  • Other References
  • Claim(s)
  • Description/Specification

The third method of limiting the search is to specify the Issue/Publication Date Range.

Once the user has completed their search strategy, they should choose how many results per page they wish to be displayed.

When finished, the user should click the "Search" button. The DNA Patent database will process the request and display the search results.

Advanced Search

The Advanced Search screen is composed of many search boxes and a few search limiters. All of the features of the Basic Search screen appear with a few enhancements.

The first method of limiting the search is to use the drop-down lists to the right of each of the aforementioned search boxes. The user may select one of three options:

  • All of the words - This option will retrieve records that contain all of the words the user has entered in the search box. This option uses the Boolean operator "AND."
  • Any of these words - This option will retrieve records that contain any of the words the user has entered in the search box. This option uses the Boolean operator "OR."
  • Exact phrase only - This option will retrieve records that contain the exact phrase the user has entered in the search box. This option uses the Boolean operator "ADJ." (Note: placing quotes around a name (e.g. "American Medical Association") or a term (e.g. "HIV infection") is the same as selecting the "Exact phrase only" operator.)

The second method of limiting the search is to choose a field for each of the search boxes in which the user has entered search terms. The user may choose the "all fields" option or a specific field. This enhancement allows the user to limit certain search terms to one field and other search terms to another field. Please refer to the Basic Search tips section above for a list of the available fields.

The third method of limiting the search is to specify the Issue/Publication Date Range.

Once the user has completed their search strategy, they should choose how many results per page they wish to be displayed.

When finished, the user should click the "Search" button. The DNA Patent database will process the request and display the search results.

Boolean Search

The Boolean Search screen is composed of one main search box and a few search limiters. The user can enter their search in the "Search Query " box.

Database fields should be enclosed by square brackets "[ ]" when included in the search query. See the sample search below.

Sample search: hiv[ti] and vaccin+[ab]

The user is searching for the term "hiv" in the title field and all truncated forms of the term "vaccin", e.g., vaccine, vaccines, vaccination, etc., in the abstract field.

Fields available for searching include:

Field Code Field Name   Field Code Field Name
TI Title GOTX Government Interest
AB Abstract LREP Attorney or Agent
PD Issue/Publication Date PCTA PCT Information
PN Patent/Application Number PKCD Publication Document Kind Code(s)
APPD Application Date PRFR Foreign Priority
AP Application Serial Number RE Reissue Data
AS Assignee Name, City, State, or Country RLAP Related US App. Data
CIPC International Classification UREF Referenced By
ORCL Current US Classification FREF Foreign References
PEXM Primary Examiner OREF Other References
AEXM Assistant Examiner ACLM Claim(s)
INVS Inventor Name, City, State, or Country PPDB Description/Specification

The user may choose to turn "Plurals" on or off for their search. When "Plurals" is turned on, the search will look for both the singular and plural forms of the terms in the search query. For example, if the user searched for "vaccine," the database would also include any results that used the term "vaccines." When "Plurals" is turned off, the search will only look for the term exactly as the user has typed it. For example, if the user searched for "vaccine," the database would only look for the term "vaccine." It would not return any results that used the term "vaccines."

The user may also limit the search by specifying the Issue/Publication Date Range.

Once the user has completed their search strategy, they should choose how many results per page they wish to be displayed.

When finished, the user should click the "Search" button. The DNA Patent database will process the request and display the search results.

Saving Your Search Results

To save all citations within the display page, click on the "Save All" button. NOTE: Citations must be saved before going to the next page of results. For large retrieval results, set the display to the maximum number of cites (325). Retrieval results larger than 325 can be saved/printed 325 citations at a time.

Once you have clicked the "Save All" button, a file download dialog will appear. Complete the following five steps:

  1. Click the "Save" button.
  2. From the "Save in" drop-down list, choose the folder in which you wish to save your search results, e.g. C:\My Documents.
  3. In the "File name" box, type a file name that means something to you, e.g. "hiv vaccine patents.htm"
    NOTE: You must add the ".htm" to the end of your file name. This will help your computer know which program it should use to open the file, e.g. Microsoft Internet Explorer, Netscape, Mozilla, Firefox, or another HTML viewing program.
  4. In the "Save as type" box, select the "All Files" option.
  5. Finally, click the "Save" button.
