jamornini: I took and passed the exam way back when it was written, and you had to draft a real claim. Don't mean to crow (ok a little) but the pass rate was < 40% (but that included re-takers who had previously bombed). I took a 5 day course (PLI if I remember), studied the big 4 for about 10 days, 6-8 hours per day thereafter (no more), and took as many practice exams as I could get my mits on. Remember its multiple guess. Of the 4 or 5 answers you get to choose from (I don't know format), 2 or 3 will be stupid, ur down to 2 or 3. Pick the best answer, there might not be a singularly right one. When all else fails, pick "b" and move on, or flag and come back. You will not score 100%, fuggedaboutit. Standard rules for multiple guess exams apply. Watch the clock and don't let a few questions throw you. You will get some wrong and it is pass-fail. Think of it as a computer game (Objection!(R) helped me get an A+ in evidence and was a gas to play, even w/ ancient 1997 graphics).
There seems to be a split of authority here concerning whether prep courses are worth the money. I took one (paid by my employer) and passed. Could I have passed w/out it? Maybe, maybe not. We'll never know unless the USPTO institutes periodic recertification. It's a matter of math. What does the course cost? How long would you work as an agent/atty? How much $ would the money spent earn in interest over that period? How much income bump to you rationally expect if you pass the exam? Subtract the first and penultimate #s from the ultimate #, look at the result, adjust for inflation where necessary, and make a simple "economic man"decison. QED.
As other practitioners have asked other agent/attorney wannabies on all "becoming a patent agent / lawyer" threads, do you want to be an agent/atty? If yes, give urself every opportunity to suceed. Can't afford whatever they charge these days? Stick to the big 4 and take every practice exam you can. It's LSAT / GRE all over again. Not sure ur are a wannabie? Save ur $ and think it over 'till next exam. You really want to do this? Then do it, take a PLI or PRG course and give urself every advantage. Uncommitted? Stay on the porch.
