I can find plenty of guides on Patents, Copyright, trademarks and design rights but I cannot find a basic guide on the above. I have looked on the IPO web site but there is very little information available. As a small business I am interested in this information so I can understand how I can use this as a vehicle to enter the US market and generate some revenue.
You can find a wealth of information on how to enter the US market on the UKTI USA website including business opportunities :
I hope this helps.
