DYSON unrelated

As I stumbled on an entrepreneurship and innovation note I made during class, when a substitute lecturer came in to help the class as our main teacher was away. I decided to blog my notes. He talked about large company innovation- DYSON
Dyson was/is an engineer by trade and he had tried to innovate and work around different existing products, such as the wheel barrow.
He made an already existing hoover into one domestic appliance that people today can relate his name to, he made an existing innovation better! 
He also made the see-through hoover that would help the user know when to empty it. With this; he was told by his marketing advisors that he could charge whatever price he wanted. With that being said, he charged the highest premium to customers. 
In addition, he got an 8 year patent. Meaning that others won't be able to copy his 'style' until the 8 years had run out...this gave him an advantage over his competition. 
He built a UK factory and stated that he wanted to improve and increase british manufacturing. After 8 years, his competitors copied his idea and outsourced and assembled their products with cheaper material and manpower. This was detrimental to his business as he had to reduce his prices to try and beat or compete with his competition. 
After a while he eventually and regrettably had to move his manufacturing plants outside the UK. Something he didn't ever want to do. 
The longest patent ever is said to be 25 years, patents protects the investors as it helps them recoup their money back. It also creates innovation as others will try to 'find a way around' so to speak. 
Apparently...Dyson now lives in a 'subsistence economy' where he just has enough to survive.
