This table is usually updated every Tuesday evening in US Eastern time, and is current as of August 9, 2022.

The columns are defined as follows:

  • Inventor: The name of the inventor.
  • Patents: The number of utility patents that have been issued. Only utility patents (or the international equivalent) are listed, as a utility patent is a patent for an invention. Not all patents are for inventions. Other patent types include: design patents for the ornamental design of an object; plant patents for plant varieties; and reissue patents, where a correction is made to an already granted patent. This list does not include patent applications (patents pending) as there is no guarantee that a patent application actually describes a novel invention until the patent is granted.
  • Residence: The country of inventor's residence listed in their most recent patent issuance.
  • Patent Years: The first and last year in which an inventor received a patent issuance.
  • Years: The number of years from first issuance to most recent issuance.
  • Patents / Year: The average number of patents received per year [Patents column divided by Years column, rounded].
  • Inventors / Patent: The average number of inventors listed on the inventor's most recent 50 patents as of September 7, 2021 or on the date the inventor was added to the table if later. "NA" signifies the inventor was active prior to digital records. Data is automated from the USPTO. This column requires 50 page loads per inventor, which is over 15,000 in total. Pages are not requested in parallel, wait for prior request to complete, and pause between requests to never burden the source. Therefore, it will seldom be refreshed due to automation run time and need to protect the source.
  • Majority assignment: The entity that has the most patents assigned from an inventor's portfolio. This is current and not original assignment. It is usually, but not always an indication of which company the inventor worked at for the majority of their patent activity.

Threshold for inclusion[edit]

As the average number of patents per inventor is around 3, some sources define prolific inventors as five times above the average (in terms of patents), leading to a threshold of 15 patents.[Info 4] However, this table currently has an arbitrary cut-off limit for inclusion of 200 patents. This is purely for practical reasons – there are tens of thousands of inventors with more than 15 patents. The threshold of 200 patents means that some famous prolific inventors such as Nikola Tesla are not included in this list, as Tesla had 111 patents.[Info 5][Info 6]

Significance of inventions[edit]

This table is a sortable list of the most prolific inventors as measured by utility patents granted. It does not include other types of invention, such as inventions that were never applied for nor granted, for which there is no known source. Nor does the table attempt to measure the significance of an inventor and their inventions. The significance of inventions is often not apparent until many decades after the invention has been made. For recent inventors, it is not yet possible to determine their place in history.

Various published lists[edit]

Rankings of prolific inventors have been published at various times. However, until the patent records were digitized, these lists were very tedious to prepare, as many thousands of patent records had to be checked manually. Even after digitization, it is still not a simple process. While the USPTO keeps statistics for annual rankings of inventions assigned to companies, it no longer publishes rankings of individual inventors. The last such list was published by the USPTO in 1998.[Info 7] Also, patents predating 1976 have not yet been digitized in the USPTO records. This means that patents before 1976 will not be included in a USPTO search by inventor name, and the number of patents granted before 1976 must be added to current searches.

Popular Science (1936)[edit]

In January 1936, Popular Science published a list of the "most prolific living inventors to be found in America today".

Rank Inventor U.S. Patents
1 John F. O'Connor 949
2 Elihu Thomson 696
3 Carleton Ellis 648
4 Henry A. Wise Wood 434
5 John Hays Hammond Jr. 360
6 Clyde C. Farmer 344
7 Ethan I. Dodds 321
8 Edward Weston 309

Thomas Edison was not included in the list, as he died in 1931, five years earlier.

Time Magazine (2000)[edit]

On December 4, 2000, Time Magazine published a list of the "top five inventors".

Rank Inventor U.S. Patents
1 Thomas Edison 1,093
2 Melvin De Groote 925
3 Francis H. Richards 894
4 Elihu Thomson 696
5 Jerome Lemelson 554

This list only included U.S. inventors, so omitted Canadian inventor George Albert Lyon, with 993 U.S. patents at the time of publication, Japanese inventor Shunpei Yamazaki, with 745 U.S. patents, and Béla Barényi, with 595 German patents. Also omitted were John F. O'Connor with 949 U.S. patents, and Carleton Ellis, with 753 U.S. patents at the time of publication.

USA Today (2005)[edit]

On December 13, 2005, USA Today published a list of "the top 10 living U.S. patent holders":[Info 8]

Rank Inventor U.S. Patents
1 Shunpei Yamazaki 1,432
2 Donald Weder 1,322
3 Kia Silverbrook 810
4 George Spector 723
5 Gurtej Sandhu 576
6 Warren Farnworth 547
7 Salman Akram 527
8 Mark Gardner 512
9 Heinz Focke 508
10 Joseph Straeter 477

This research was performed by ipIQ of Chicago (now "The Patent Board"[Info 9]) and 1790 Analytics[Info 10] of New Jersey. This list only considered living inventors, and thus did not include prolific inventors such as Thomas Edison, Melvin De Groote, and Elihu Thomson. This list included design patents, which are not patents for inventions.

Condé Nast Portfolio (2007)[edit]

On October 15, 2007, Condé Nast Portfolio Magazine published a list[Info 11] of "the world's most prolific inventors alive":

Rank Inventor U.S. Patents
1 Shunpei Yamazaki 1,811
2 Kia Silverbrook 1,646
3 Donald Weder 1,350
4 George Spector 722
5 Gurtej Sandhu 674
6 Leonard Forbes 671
7 Warren Farnworth 635
8 Salman Akram 612
9 Mark Gardner 515
10 Joseph Straeter 485

This research was performed by The Patent Board,[Info 9] a Chicago patent research and advisory firm. As with the USA Today list, the Portfolio list only considered living inventors, and thus did not include such prolific inventors as Thomas Edison. This list also included design patents, which are not patents for inventions.

Business Insider (2011)[edit]

On May 6, 2011, Business Insider published an article titled: "The Ten Greatest Inventors In The Modern Era"[Info 12] containing the following list:

Rank Inventor U.S. Patents
1 Kia Silverbrook 3,847
2 Shunpei Yamazaki 2,061
3 Thomas Edison 1,084
4 George Albert Lyon 993
5 Paul Lapstun 969
6 Donald Weder 951
7 John F. O'Connor 949
8 Leonard Forbes 948
9 Melvin De Groote 925
10 Francis H. Richards 894

This list included living and dead inventors, and only included granted utility patents (patents for inventions).

Strutpatent.com (2012)[edit]

Strutpatent.com publishes a list of the "Top 10 Inventors"[Info 13] listing inventors ranked by US patents (of all types) issued since 1990:

Differences between lists[edit]

Differences in patent numbers between the various lists are due to several reasons:

  • The lists were created on different dates. As many of the inventors in the lists are still active, the number of patents they hold are increasing.
  • While the U.S. Patent and Trademark Office (USPTO) is the primary source for U.S. patent information, only patents issued since 1976 can be electronically searched by the inventor's name at the USPTO website. For some of the listed inventors, such as Thomas Edison, all of their patents predate 1976, so other sources must be used.
  • Often entities list the worldwide total number of patents that they hold. This is not the same as the number of inventions, as a patent in one country may be for the same invention as a patent in another country. The set of patents covering a single invention in different countries is a Patent family.
  • The Time, USA Today and Portfolio lists show the total number of U.S. patents, including patents for designs (Design patents) as well as patents for inventions (Utility patents).
  • The annual lists from strutpatent.com list only those patents issued in the particular year to the inventor, not all of the inventor's patents.
