The story of success of the iENA

Tradition and Future: iENA celebrates its 65th anniversary - and can look back on a long, successful history. It started off small, and in the first years essentially represented a showcase for bizarre and whimsical ideas. Today, it is the most important international trade fair for the inventor community, and Germany's only inventor fair with a true global image.

The huge amount of interest from inventors, associations and organizations associated with inventions of all types and the new cooperation with the START Messe Bavaria, which will take place for the first time in collaboration with iENA, certainly point to a strong anniversary fair.

"Inventors are tinkerers. They are like Gyro Gearloose and things just do not turn out as intended at times." However, inventors have long left this image behind. We just could not do without many of their inventions in our modern day life anymore. Think about trolleys, for example, or the folding bicycle, inline skates, the snow board or retractable dog leads. 

These products, which meanwhile add up to 25 000 inventions, all started their success at the iENA – International Trade Fair “Ideas – Inventions – New Products” at Nuremberg.
