EPO announces winners of the European Inventor Award 2021


The European Patent Office (EPO) today announced the winners of the European Inventor Award 2021, its prestigious annual innovation prize.  The individuals and teams were recognised for their innovative contributions in the fields of nasal drug delivery, DNA-based data storage, nanomaterials in dentistry, solar cells for self-charging devices, organic semiconductors, and advances in tissue engineering.

"In these challenging times, it is inspiring to see the creativity and dedication shown by these inventors in bringing innovative solutions to the world," said EPO President António Campinos. "Their achievements remind us that obstacles can be overcome by applying imagination, knowledge and ingenuity. The ability to take a new idea all the way to market also demands perseverance and a supportive environment for innovation, and the finalists and winners of the European Inventor Award 2021 are all testament to this."

This year's winners were chosen from a pool of hundreds of inventors and teams of inventors put forward for the award; they come from Austria, Germany, India, Norway, Serbia, Sweden, Switzerland, and the United States.

Now in its 15th year, the European Inventor Award is presented annually by the EPO to distinguish outstanding individuals from Europe and beyond who have made an exceptional contribution to society, technological progress and economic growth. The finalists and winners in five categories were selected by an independent international jury. They have all made use of the European patent system to protect their technologies and, in so doing, enabled other researchers and inventors to build on their innovations.

This year's Award ceremony, held for the first time as a digital event, was open to the public, who tuned in from around the world as the winners were announced.

The laureates of the European Inventor Award 2021 are:


Better nasal drug delivery

The Norwegian inventor's medical device uses the nose's natural form and the patient's own breath to improve nasal drug delivery and provide relief for various conditions. The invention helped grow a company that is now stock-exchange listed and develops innovative medical solutions - a breath of fresh air for patients.


DNA-based data storage

The Austrian and Swiss inventors developed a novel method of preserving data converted into genetic code using artificial fossilisation in tiny glass spheres. They created a storage format with the potential to protect valuable data for millennia, as well as a robust DNA barcode: when their miniscule particles are applied to products, they ensure that specific indicators - such as the origin or working conditions - are traceable throughout the supply chain. 

Non-EPO countries

Restoring smiles with nanomaterials

This researcher found that nanoclusters could be used in dentistry, resulting in robust, durable and aesthetically pleasing fillings. Her material overcomes many of the limitations of previous dental composites, which were either too weak to be used on biting surfaces, or quickly lost their polish. These tiny clusters have been used in one billion dental restorations worldwide.

Small and medium-sized enterprises (SMEs)

Flexible solar cells for portable devices

From their plant in Stockholm, the inventors produce a dye-sensitised solar cell using a new electrode material with very high conductivity that can be custom-printed in almost any shape or colour, and can even generate electricity indoors. Thanks to this versatility, the cells are being integrated into various electronics to create self-charging devices.

Lifetime achievement

Advances in organic semiconductors

The German physicist advanced organic semiconductors by improving their conductivity through a technique called doping, ushering in a new generation of highly efficient organic light-emitting diode (OLED) displays. His OLEDs provide enhanced image brightness, colour resolution and power efficiency in electronic devices. Currently, half of the world's smartphones and many types of ultralight organic solar cells incorporate his technology. He has also founded several companies in a career spanning over 30 years.

Popular Prize

Advances in tissue engineering

The Popular Prize, awarded to one of the 15 finalists through an online public vote, this year went to Serbian-American biomedical engineer Gordana Vunjak-Novakovic. She has opened new horizons in regenerative medicine by developing a way of growing new tissue ex vivo (outside the body) using the patient's own cells. The Popular Prize is designed to honour the inventor or team of inventors that have both inspired and impressed the general public with their creativity and genius.

About the European Inventor Award

The European Inventor Award is one of Europe's most prestigious innovation prizes. Launched by the EPO in 2006, it honours individual inventors and teams of inventors whose pioneering inventions provide answers to some of the biggest challenges of our times. The finalists and winners are selected by an independent jury consisting of international authorities from the fields of business, politics, science, academia and research who examine the proposals for their contribution towards technical progress, social development, economic prosperity and job creation in Europe. The Award is conferred in five categories (Industry, Research, SMEs, Non-EPO countries and Lifetime achievement). In addition, the public selects the winner of the Popular Prize from among the 15 finalists through online voting.

About the EPO

With 6 400 staff, the European Patent Office (EPO) is one of the largest public service institutions in Europe. Headquartered in Munich with offices in Berlin, Brussels, The Hague and Vienna, the EPO was founded with the aim of strengthening co-operation on patents in Europe. Through the EPO's centralised patent granting procedure, inventors are able to obtain high-quality patent protection in up to 44 countries, covering a market of some 700 million people. The EPO is also the world's leading authority in patent information and patent searching.
