Sequence	Inventor	Lived	Country	Patented inventions	Main fields of invention	Remarks, Notable inventions
1	Kia Silverbrook*	1958–	Australia	4669	Printing, Digital paper, Internet, Electronics, CGI, Chemical, DNA, Lab-on-a-chip, MEMS, Mechanical, VLSI	He holds patents in a diverse set of fields, from digital music synthesis to mechanical engineering. Silverbrook notably invented Memjet, a high-speed color printing technology.
2	Shunpei Yamazaki	1942–	Japan	3525	Thin film transistors, Liquid crystal displays, Solar cells, Flash memory, OLED	His notable work is the thin-film transistor (pictured). It's a special kind of transistor made by depositing thin films of a semiconductor over a piece of glass, and it's how LCD displays work.
3	Paul Lapstun	19??–	Australia	1268	Printing, Digital paper, Internet, Electronics, CGI, VLSI	He is Kia Silverbrook's co-worker. He notably invented a system that lets someone send an email to another person only if they have that person's electronic business card.
4	Gurtej Sandhu	1960–	United States	1095	Thin film processes and materials, VLSI, Semiconductor device fabrication	Sandhu developed a method of coating microchips with titanium without exposing the metal to oxygen, which would ruin the chips.
5	Thomas Edison	1847–1931	United States	1084	Electric power, Lighting, Batteries, Phonograph, Cement, Telegraphy, Mining	He famously invented the light bulb, the phonograph, electric car, and an improved typewriter that perforated paper.
6	Leonard Forbes	1940–	United States	1055	Semiconductor Memories, CCDs, Thin film processes and materials, VLSI	Forbes  has lived quite an academic life - he's taught at University of California at Davis, University of Arkansas Fayetteville, Portland State University, and Oregon State. Notable work includes a method for stacking semiconductors in a wafer for increased performance.
7	George Albert Lyon	1882–1961	Canada	993	Automotive, Stainless steel products	He invented the automobile bumper, saving lives and minimizing damage.
8	Donald Weder	1947–	United States	992	Florist supplies	Weder's patents are all related to the floristry industry. He created various ways to wrap flowers and flower pots, and different materials to use for doing so.
9	Jun Koyama	19??–	Japan	954	Thin film transistors, Liquid crystal displays, OLED	He joined Semiconductor Energy Laboratory Co., Ltd., Atsugi, Japan, in 1992.  Since then, he has been working on the development of TFTs and circuits.
10	John F. O'Connor	1864–1938	United States	949	Railway draft gearing	His notable invention is railway draft gearing, the system used to connect a railroad locomotive to its frame.
11	Melvin De Groote	1895–1963	United States	925	Chemical de-emulsifiers	De Groote  worked as a flavorings expert at the Mellon Institute. He was rumored to have been hired by Coca Cola to re-formulate its taste. Notable inventions include de-emulsifying agents that separate crude oil from salt, sulfur and water.
12	Francis H. Richards	1850–19??	United States	894	Mechanical, automation	Notable works include the Richards Envelope Machine, which prints, folds, gums, counts, and bands 80,000 letters envelopes per day.
13	Jay Walker	1955–	United States	810	Gaming machines	He has patenting inventions in the vending machine field with the goal of revolutionizing the vending industry through enabling smart vending technology. He  developed   technologies for dozens of networked slot machines.
14	Lowell Wood	19??–	United States	808	Mosquito laser, Nuclear weapons, Geoengineering,	He was a long-time ssociate of Ede Teller's. His research contributed to the thermonuclear fusion through the use of lasers. Under his supervision. He collaborated on the development of x-ray lasers, and early-stage testing of space-based defenses against ballistic missile attack.
15	Warren Farnworth	1954–	United States	762	Semiconductor packaging	His notable  invention includes semiconductor assemblies having two or more dies. An exemplary assembly has circuitry associated with a first die front side electrically connected to circuitry associated with a second die front side.
16	Carleton Ellis	1876–1941	United States	753	Margarine, Polyester, Anti-knock gasoline, Paint stripper	He was a pioneer in the field of organic chemistry. He is the forgotten father of margarine, polyester, anti-knock gasoline, paint and varnish remover.
17	George Spector	19??–	United States	722	Gadgets, Toys	His notable  invention the motorized pot-washing tool.
18	Salman Akram	1967–	United States	707	Semiconductor packaging	He worked together with Warren Farnworth (15) and Gurtej Sandu (4) in that great mecca of American invention, Micron Technology Co. Idaho. His inventions in the field of semiconductors.
19	Hideo Ando	19??–	Japan	697	Optical recording	His notable  invention multilayer optical disk and recording.
20	Elihu Thomson	1853–1937	United States	696	Electric power, Arc lamp, Electric motors, Lightning arrester, Arc welder	His inventions founded General Electric in US and Alstom in France. His main invention is  automatically regulated three-coil dynamo and electric welding.

Top 3 most prolific Lady Inventors

The most prolific female inventor alive is biologist Gisela Lorenz (Germany), who retired six years ago from the German chemical company BASF. Lorenz has 363  patents, mostly in the realm of  “crop protection”—fertilizers and pesticides. Her prolificacy is partly because she oversaw a team of researchers and her name went on patents she worked on regardless of whether or not the main idea was hers.

 Two of the other top women are Jennifer Hillman and Olga Bandman (USA), who both worked for the U.S. biotech company Incyte and have 327 and 250 patents, respectively.
