What I do:
I write complex technical/legal documents and argue with patent examiners over what my applications can cover. It's hard work and requires long periods of fairly intense concentration.
How much money we make:
It varies wildly. Rates charged to clients range from $100/hour to $400/hour. As a general rule of thumb, the attorney gets to keep half of that as income. But that rate of profit also varies wildly. And those hours are billable hours -- billed to a client, no money for lunch breaks, vacations, etc. 1500 hours a year is a fairly comfortable pace, while 2000 hours per year is rather difficult for patent attorneys.
Oh, and you can discount those rates by about 25% or more for patent agents relative to patent attorneys.
Meetings:
There are conferences that patent attorneys go to from time to time. Attorneys within the same firm will see each other all the time.
If you're thinking of meetings you can attend, I can look around and see what I can find that's relatively inexpensive and in the Michigan area.
Education:
You have to have some technical degree to be a patent attorney. Life sciences are good (biology, chemistry, etc.). Physics is good to. Engineering is always good. I was a computer science major. At high school and college, you should be working toward your technical degree and ignoring law school until you have your undergraduate degree. The good news is that you are free to pick a technical discipline which interests you.
I hope that helps.
Regards.
