1. Use your spreadsheet software's concatenate function to create a list of application numbers with " OR " between each application number.  Notice that the format is "spaceORspace" between the numbers.  It won't work without the spaces!
2. Copy the last cell from Column B into your copy buffer.

1. The query you make will look like the example above.  
2. Notice the query is in the following form: APN:(5/894785 OR 15/431768 OR 11/514911...).
3. Be sure to include the parentheses around the entire set of application numbers.  This is so the APN field query applies to the entire set.

This technique works well with 1,000 or fewer document numbers.  If you need to query more than 1,000 application numbers, then break up the query into two or more APN clauses with no more than 1,000 application numbers per clause.  For example:

APN:(5/894785 OR 15/431768 OR 11/514911 OR...) OR APN:(12/720383 OR 12/675630 OR 12/560361 OR ...)

This is still one query, but it is broken down into multiple APN clauses.

Note that you can also, in your Excel worksheet, add a blank column next to the application number column, and simply add OR all the way down (except for the last application number).  Then copy both columns at the same time and insert them into the APN search's parenthesis.  This is much less clean than the above method, but does also work.

Once you have run the search, you can save your results to a Research Folder (1) from the Search Results window.

Depending on what APNs you use, you may find that the results are sparse.  Remember that AcclaimIP has access to the public data.  If the document is not yet published, AcclaimIP will not recognize the number.  In other words, the search results will only include those APNs with a corresponding published document.
