1. Is it a good idea to take the patent bar exam and become a patent agent to get a feel for the career before diving into law school? Is this a recommended path? I hear that most of the patent work is in prosecution which I could do as a patent agent. To me this is a good way to try the field though I do want to get into patent litigation since that sounds far more interesting that patent prosecution.
Yes. The benefits of taking the patent bar outweigh the costs. There's no real downside to taking it, other than the small cost and inconvenience of registration and studying.
Just don't quit your day job.
Given my background, how likely is it that, if I go to a top IP law school, such as Berkeley, I will be able to find a reasonable employment, given that I will have above average grades at Berkeley? By reasonable I mean >$150K in the west coast region. I will be accruing some debt by taking a few years off from the work force and need to make good money to pay that off.
What the heck does "given that I will have above average grades at Berkeley" mean? How is that given?
According to U.S. News, Berkeley is roughly the eighth/ninth best - meaning toughest - law school in the country. Its students have an average undergrad GPA that is exceptionally high. You could be a Merit Scholar, valedictorian of your high school, and a philosophy and pre-law double major, and still not be guaranteed to do better than the average Berkeley student. Remember that even the best law students (and many law professors) will concede that law school grades have a significant randomness component. And many or most "engineering students" find the "one long essay at the end of the semester with no practice" metric to be frustrating at best.
You're not even guaranteed to get into Berkeley, much less do above-average there!
Now, if you do get into Berkeley, and if you do above-average there, then yes, you will probably be able to get a good patent attorney job, and one that pays around $150k - since you seem so focused on salary (note that you are already make a very respectable amount of money). But we've already made many "what if's" along the way. You simply cannot assume that these things will happen. Period.
3. Is there anything I can do other than score high on the LSATs that could improve my chances of getting into good law schools? Would a short stint as patent agent help that cause or hurt it? This ties in to question #1.
Patent agent or clerk work would provide marginal benefit in law school applications, which will be mostly focused on GPA and LSAT, and to a lesser extent work experience (of which you already have plenty). But patent work provides another invaluable benefit: it lets you determine whether you would really enjoy working in patent law. It's irrational to leap into three years of school, and ~$150k in debt, to switch into a career that aren't sure you will love. Test the waters.
I strongly recommend that you work part time, or in an internship, doing patent law, simply to evaluate how you like it as a career. Remember that jobs paying $150k+ usually require you to work huge amounts of hours.
Here is my advice to you:
1. try to work in patent law without committing to law school or debt
2. focus more on obtaining the best financial aid (free money) package instead of obtaining the best law school pedigree (remember that pedigree matters less for patent attorneys - we're already special)
3. absolutely do not assume that you will take on debt to go to law school - in fact, do NOT take on any substantial debt.
4. look for a part time law school program that lets you keep your cushy job (or another job) - sometimes the admissions requirements are relaxed (esp. if you apply) early, but the degree is just as prestigious.
5. rid yourself of delusions about law school by reading all of the posts at

There is no reason for someone making as much as you, with your background, to take on debt to go to law school, much less the big $100-200k debt that is typical of law students.
Last thought - given your "entrepreneurial" spirit, it sounds like you are a more maverick and independent thinker, and not someone who would enjoy slaving away and taking orders for 10 years at a white shoe firm to eventually make partner. But those are the firms that will pay you salaries like $150k. Think about it.
