The current IP system stifles invention; all IP’s should be available to anyone for a realistic license fee. That way we would get innovation of the basic idea into something better.
The IP holder would get revenue and the consumer would get a choice. The biggest losers would be the lawyers.
But none of this is new; lawyers working for James Watt held back the development of high pressure steam for years using patent laws.
I wonder how successful Dyson would have been if his business plan had to include a million or so for lawyers to fight some aggressive companies IP claims.
I think he should count his luck that Apple were not making domestic appliances!
