Totals are also divided according to general category of ownership, e.g., corporate-owned, government-owned, or individual-owned. Part B of each Technology Workload Report shows the national and international corporations, government agencies and other organizations that have received the most patents during the period. It ranks these organizations in terms of total patent receipts and profiles their annual patenting activity for the most recent 14 year period. Patent grants are distributed in two ways, by year of grant and by year of patent application. (updated irregularly)

## Miscellaneous Information

Link with Technological Activity

  Most analyses of technological activity that incorporate patent data will focus on the activity of utility patents, also known as "patents for inventions." Since design patents are granted for ornamental designs and not for inventions, they are usually perceived to have a lesser relationship with technological activity. Similarly, statutory invention registrations and defensive publications do not convey patent protection to disclosed inventions and may have a lesser relationship with technological activity. Plant patents may or may not disclose an invention; however, plant patents are numerically small relative to utility patents and are usually handled and analyzed separately.

Other PTMB Reports

  For a description of other available PTMB reports, please view the PTMB Brochure.

Other Sources of USPTO Statistical Data

  Other statistical data relating to patents may be found in the Commissioner's Annual Reports / Annual Performance and Accountability Reports as well as in other documents available at the USPTO Web Site.

  Please note that data contained in the Commissioner's Annual Reports / Annual Performance and Accountability Reports are predominantly fiscal year data covering annual periods that extend from October 1 to September 30.

  The Commissioner's Annual Reports / Annual Performance and Accountability Reports as well as other patent data on the USPTO Web Site may be accessed from the U.S. Patent and Trademark Office Home Page (http://www.uspto.gov).

Statistical Data From Other Intellectual Property Offices

  For statistical data profiling patenting activity at intellectual property offices outside the United States, the web sites of those offices should be consulted. Please note that patents granted by the U.S. Patent and Trademark Office provide patent protection only within the United States.

File Formats For Viewable and Downloadable PTMB Reports

  PTMB reports that are available for downloading are either in Adobe ® Acrobat ® format (".pdf" file extension), in ASCII text format (".txt" file extension), or in HTML Hypertext format (".htm" file extension). Links to free software for viewing and printing PDF files may be obtained at the USPTO Web Site's Document Formats and Viewers page.

  Please note that table data in some of the PTMB HTML Hypertext format files can be directly imported into many newer software programs (e.g., newer spreadsheet software).

Frequency of Updating of PTMB Reports

  Updates to PTMB General Statistical Reports are usually generated in March/April of each year to incorporate data through December of the previous year. Midyear updates may be generated for some PTMB reports with the update reports containing data through June. These update reports, if generated, are generally available in late July to early August. One exception is the "U.S. Patent Statistics Report", which is fully updated in May/June of each year.

  PTMB single year reports are usually generated in February of the following year. The "Patenting By Organizations Report", however, is updated once per year in March/April.
