That's how our justice system works. I'm glad that any citizen gets to be on a jury rather than some elite set of experts. We can't have it both ways. If given the choice between "experts" and average citizens on a jury I'd go with average citizens every time. I don't care how dumb or smart they are. What I care about is if we decide that a certain kind of person should be on certain juries then that creates a new kind of class system and would hurt us more than help. The job of the lawyers throughout the trial was to explain these things to the jury and give them the information they need to make a decision. It's fine to have a jury full of people who have no clue about the patent system because the onus is on th lawyers in the trial to present the facts. If they fail to do so on either side then they have to deal with the consequences.

It's not fair but it's equal. America's judicial system is not about fairness so much as it is equality. Equality isn't always fair but in a country like this it's the best we can do.

Now what I'm about to say isn't an attack on you but instead just am observation. When people disagree with something they always try to explain why the bad thing happened. In this case it sounds like you're looking to explain away a decision you disagree with by saying the jurors should have been experts. If the jurors were experts and someone disagreed with the ruling then inevitably someone else would be sayng they should not be experts because of bias or some such reason.
