The US law Apple used is only relevant if the product is sold in the USA, and the same cases on the same issues in other courts went the other way. Thus a company can avoid this complication of the US laws by simply NOT selling a product they're concerned about in the US markets.
If the 'offending' product is not sold in the US, then a US company can not use the US laws to sue them over it. If a company has concerns, they need only have the product marked for sale on their non USA website as 'not for sale in the USA' and they can't be touched. They should also include a link to a page explaining why it's not for sale in the USA.
Mind you, that won't stop US people from buying them from retailers and having them shipped to them personally.
The real crunch in this system will be with products that are useful to the US business that failure to have could affect their stand in the world markets.
