Notes
-----

This custom patent data extract file includes PATENT TITLE information 
displayed on the front page of issuing U.S. patents. PATENT TITLE
information is included for:

 - utility patents (i.e., "patents for inventions") issued by 
    the U.S. Patent and Trademark Office (USPTO) from 
    1/1/1975 to 12/31/2015 and 
 - design, plant, and reissue patents, defensive publications, and statutory invention 
    registrations issued from 1/1/1977 to 12/31/2015.

See the U.S. Patent and Trademark Office Manual of Patent Examining 
Procedure for further information relating to patent titles.


    File name: PTITLE_15.TXT
    5,882,078 records, CY 2015
    File size: 372,447,063 bytes (about 372 MB)



- The "PTITLE_15.TXT" file format is as follows:

    - Columns 1-7  : Issued patent/document number that contains 
                     the patent title information (character field)
                     
    - Columns 9-263 : Patent title text (character field); this field may be truncated



The PTITLE_15.TXT file is sorted by ascending patent number (primary).

Each line is terminated with a carriage return and a line feed character (0D 0A
in hexadecimal) after the last populated data field.




- A list of the patent numbers that do not correspond to actual patents in the data extract
  file is included in the file, "WITHDRAWN_75_15_PN.TXT". Since these "withdrawn" patent 
  numbers do not correspond to valid documents, they are excluded, as patents, from the 
  data extract files.

- Issued U.S. patents that are missing from the data extract file are listed in a separate 
  file, "MISSING_PTITLE_15.TXT". In general, patent documents within the identified 
  time ranges that are missing from the data file are missing because the corresponding 
  data were omitted from the original electronic text files produced for the patents 
  issued each week. 

- A file "LASTPN_15.TXT" has been provided that displays the last patent number by year and
  patent document type.

- The data are sorted by ascending U.S. patent number.

- A small sample of the data contained in the custom extract data file, "PTITLE_15.TXT", is 
  included in a separate file, "SAMPLE_PTITLE_15.TXT".
