# Calendar Year Patent Statistics (January 1 to December 31) General Patent Statistics Reports Available For Viewing

Notes for Users

- PTMT reports display patent statistics and data by calendar year (1 January to 31 December).
- For most users, PTMT reports displaying utility patent statistics will be the ones of interest - utility patents are also known as “patents for inventions.”
- PTMT reports that have a PDF file extension (e.g., “topo_09.pdf”) may be viewed using free Adobe ® Acrobat ® Reader software, version 6.0 or higher. This software also permits document printing. Some reports also may be viewed with earlier versions of the Adobe ® software. In general, where both HTML and PDF versions of a report are available, the PDF version is preferable when the user wants to print the report.
- The most recently updated PTMT reports include data for patents granted through 2009.

Reports By Patented Technology

Selected Technology Reports

PTMT selected technology reports are updated periodically and consist of the following parts:

- Part A1 provides a count for utility patents (i.e., “patents for inventions”) granted during the reporting period. The utility patent grants are distributed by origin, as determined by the residence of the first-named inventor, and by year of grant. The grants also are distributed separately by the general category of ownership (e.g., corporate-owned, government-owned, or individual-owned) and by year of grant. Annual counts are displayed for each of the last 14 years.
- Part A2 displays the same breakouts as in Part A1 but with the patents distributed by the year of application.
- Part B shows the national and international corporations, government agencies, and other organizations that have received the most utility patents during the reporting period. Patent grants are distributed by year of grant and by year of application with annual counts displayed for each of the last 14 years.
