CLAIMS^®/U.S. Patents Reloaded and Enhanced with Pre-Grant Published Applications

Several enhancements and the addition of pre-grant published applications occurred during the recent reload of CLAIMS/U.S. Patents files (Files 340,341).

• CLAIMS/U.S. Patents files now contain the annual updates to the U.S. Classification codes assigned to existing patents to match classification changes made by the United States Patent and Trademark Office (USPTO) during 2001 and 2000.
  
  
• U.S. application number searching has been enhanced. Dialog users may now search application filing numbers including the series code, following the format of application filing numbers on the front page of the patent.
  
  

?E AN=09-308663 Ref Items Index-term E1 1 AN=09-308661 E2 1 AN=09-308662 E3 1 *AN=09-308663 E4 1 AN=09-308664 E5 1 AN=09-308666 E6 1 AN=09-308668 E7 1 AN=09-308669 E8 1 AN=09-30867 E9 1 AN=09-308673 E10 1 AN=09-308674 E11 1 AN=09-308675 E12 1 AN=09-308676 Enter P or PAGE for more ?S E3 S1 1 AN="09-308663"


Application numbers are also searchable including the Country Code, e.g., S AN=US 09-308663. Note: You can also EXPAND the application numbers to see the year code at the end of the number, a handy feature when only the number is known but not the year or series.


• Pre-grant published applications are searchable using the Patent Number (PN=) field and are published each Thursday. File 340 is now updated two times a week. Granted patents are published each Tuesday, and published applications each Thursday.
  
  Since File 340 now has two updates, Alerts are processed twice a week, the first containing information from the Tuesday update and the second with records from the Thursday update. The weekly Alert profile price will not increase, and only one profile charge per week will be applied even though two updates are received.
  
  
• Subject searches may be restricted using the Document Type (DT=) field. (See Figure 1.)

• Chemical pre-grant applications have also been enhanced with IFI's UNITERM® indexing in Files 341 and 942. Indexing that historically did not appear until several months after the publication of a granted patent is now added before grant through the pre-grant published application.
  
  
• An additional enhancement includes the formatting of Foreign References Cited (CT=) in standard Dialog format to be able to identify the correct item quickly and easily. (See Figure 2.)
  
  

Information on searching class codes is available in the Dialog seminar, Developing Patent Research Expertise, Part 1. The manual is available on the Dialog Web site at http://support.dialog.com/training/.
