It's not a problem of understanding the patents. The problem is determining novelty and non-obviousness. There are so many open-source jQuery plugins coming out all the time that a web/UI patent's novelty is going to be very hard to determine. Similarly, this ongoing flood of progress will help give new ideas to ordinary skilled programmers, rendering lots of potential "inventions" obvious.

I still contend that this is a serious problem in a legal system that includes presumption of validity.
