. In 1986 Sony finally agreed to pay royalties to Pavel, but only for sales in Germany, and only for a few models, and refused to acknowledge him as the inventor of the device.

In 1989, Andreas Pavel started new proceedings, this time going through the law courts in the UK. Seven years later, the case was dismissed and Pavel was left with $3.6 million dollars of debt for his court costs. Then in 2001, Pavel threatened Sony with legal suits in every country in which he had patented his invention. The corporation agreed to resume talks with Pavel and a settlement was finally reached in 2003.

The exact settlement fee is a closely guarded secret but European press accounts said that Pavel received a cash settlement for damages in excess of $10,000,000 and is now also receiving royalties on some Walkman sales. The settlement also includes a clause which will prevent Pavel from bringing future law suits. The settlement grants Pavel the recognition from Sony that he was the original inventor of the Walkman; this apparently could only be achieved after the death of Akio Morita
