Subject:  Drill-Down Reports Contained in Compressed Files Having a ".zip" File Extension



The compressed ".zip" files in this directory, 

http://www.uspto.gov/web/offices/ac/ido/oeip/taf/data/misc/drill_dn/YYYY, 

where YYYY is the year reported,
contain drill down report sets in compressed, archive
files. Each set of reports is contained in 
a single compressed ".zip" file as described, below.

The files contained in each compressed ".zip" file 
can be copied to separate, preferably empty directories on 
a PC and where they then can be accessed using a web browser. 
A contents or index file in each compressed file includes links 
to each of the report pages in the compressed file. The name 
of the contents or index file within each of the compressed files 
is as follows:

"asgstc_11.zip" and "asgstca_11.zip" files - start with the "regions.htm" file
"clsstc_11.zip" and "clsstca_11.zip" files - start with the "stc_cl_gd.htm" file
"tecasg_11.zip" and "tecasga_11.zip" files - start with the "classes.htm" file
"tecstc_11.zip" and "tecstca_11.zip" files - start with the "clstc_gd.htm" file

A free program for extracting the report files from the 
compressed archive ".zip" files is available by following
