Inspiration: Why do others trade in IP rights?

Companies have the opportunity to increase their innovation capability by buying and in-licensing knowledge from others instead of using resources on developing something similar.

Companies can also increase their return on research and development by letting others buy or in-license their knowledge.

Inventors that do not want to start their own company can sell or out-license their inventions. This will allow them to continue to use their time and money on new inventions.

Entrepreneurs that does not have an idea can buy or in-license ideas of others and create a business based on these.

For more inspiration on how and why to trade in IP Rights, see IP Tradeportal.
