L-Numbers and Structures

The History tab displays your session activity such as search activity, databases (files) entered, and L-numbers with answers. You also have the options to analyze an answer set, edit an uploaded structure, display an L-number structure with attributes, create a Current Awareness Alert, and manage patent families:

• Displaying an L-Number: Click an L-number to bring it to the top of the session window.

• Creating a Bar Graph or Data Occurrence Matrix: Click the Analyze Results icon to create a bar graph or matrix displaying field data occurrence for a particular L-number.

• Creating a Chemscape Analysis: Visually explore patents for a structure search result set that is based on a drawn structure

• Editing a Structure: Edit an uploaded L-number structure.

• Displaying a Structure with Attributes: Display an L-number structure with attributes.

• Creating a Current Awareness (SDI) Alert: Click the Alert (bell) icon or select Create an Alert for an L-number to create an alert.

• Managing Patent Families: Select Patent Family Manager from an L-number drop-down menu to:

• Extract the first member from each patent family and create a new L-number.

  You may also choose to include non-patent answers.

   

  

• Remove one member of a twin multiple basic patent pair from CA/CAplus answer sets, based on a comparison of CAS Registry Number® indexing.

  You have the option to keep one of the following:

  • National Office Equivalents

  • Oldest Application Date

  • PCT (WO) Equivalents

  • Oldest Publication Date
    
    

  At least one CAS Registry Number must be present in the twin basic pair. This feature works with CA/CAplus answer sets only; multifile answer sets are not allowed. Answer sets containing patents without the Chemical Indexing Equivalent tag or non-patent documents will be automatically retained in the answer set created.

   

  Note: Twin multiple basics are basic patents for the same invention for which the CAS Registry Number® indexing is exactly the same. Twin basics can be identified by the inclusion of the Chemical Indexing Equivalent tag in the SO (Source) field.

• Create a customized display of patent family results.

  Enter a display format for first member of each patent family and for additional members of each patent family.
