Throughout history and across industries, women have been quietly shaping innovation, solving everyday problems, and leaving a legacy through patents that matter. From scientific breakthroughs to clever inventions that make our daily lives easier, here are 12 women from India and around the world whose patented ideas deserve the spotlight.
A champion of green chemistry, Dr. Poonguzhali holds a patent for the eco-friendly synthesis of Benzo[b]thiophene, a compound widely used in pharmaceuticals. Her sustainable method helps reduce environmental harm in drug manufacturing.
2. Pratibha Gai (UK, Indian-origin)
A pioneering scientist in nanotechnology, Professor Gai co-invented the Environmental Transmission Electron Microscope (ETEM). This invention enables scientists to observe chemical reactions at atomic resolution, in real time.
3. Munia Ganguli (India)
Dr. Ganguli’s patented work in non-viral gene delivery systems is helping revolutionise drug delivery for genetic conditions. Her innovations at CSIR-IGIB pave the way for safer and more targeted medical treatments.
4. Sheila Sri Prakash (India)
Architect and sustainability advocate, Sheila patented a rotationally moulded prefabricated sanitation chamber, designed to improve hygiene in underserved areas. Her design is practical, cost-effective, and easy to install.
5. Sreeja Arunkumar (India)
With over 20 patents to her name, Sreeja is a powerhouse at Robert Bosch Engineering India. Her inventions in vehicle software applications include innovations in driver assistance, safety systems, and connected technologies.
6. Ann Tsukamoto (USA)
Co-patentee of a process to isolate human stem cells, Dr. Tsukamoto's invention has had a transformative effect on regenerative medicine and cancer research — offering new possibilities in treatment and recovery.
7. Nancy Johnson (USA)
In 1843, Nancy revolutionised dessert-making by inventing the hand-cranked ice cream maker. Her simple yet clever machine paved the way for home-made ice cream — long before modern refrigeration.
8. Margaret A. Wilcox (USA)
One of the earliest female inventors in the automotive world, Margaret patented the car heater in 1893. Her invention channelled warm air from the engine to the interior — making winter drives far more bearable. Her idea became the basis for modern car heating systems.
9. Melitta Bentz (Germany)
Tired of bitter coffee and messy grounds, Melitta invented the paper coffee filter in 1908 using blotting paper and a tin can. Her patent turned into a global business, and your morning brew’s clarity owes a lot to her kitchen experiment.
10. Marie Curie (France/Poland)
More than just a Nobel laureate, Marie Curie patented her work on radium and polonium for medical applications, particularly in cancer treatment. Her discoveries not only advanced science but also laid the foundation for modern radiotherapy.
