This case was too large and complex for a jury. It is very hard when experts on both sides disagree as to 'is this the same thing or not'. Often things are close but not exactly the same thing.
There were many infringements. This was not about one use of IP.
When I worked for Samsung, it was against the law for any Korean company to pay for IP. We copied many IC. I could get "Micro soft office" for $3.00. CAD programs ($9000.00) were $4.00. Korea now accepts patents. I believe the old way of thinking is still very common in Korea.
With out the intellectual property rights industry, new ideas are worth nothing. If I put millions into a new product and China copies it in 3 months, for thousands, and puts me out of business then I might as well stay in bed. No new ideas will be produced with out protection. I understand some people don't want to pay the inverter and his company. "Fundamentally new" and small improvements will not happen with out a way to pay an engineer. Being an engineer I live by the imperfect IP system, with its problems. Consumers, may not like $1.00 more a product costs. With out the IP system there would not be computers, toasters, pocket phones, etc.
