Hi. I’m in a similar situation and have a related post in the Patent Agent/Lawyers Career Forum (“Do law firms adjust billable rates for degree of difficulty?”). That post got disrupted by some petty squabbling between two posters, but if you filter that out, there’s valuable info there. My background: PhD physicist, 20+ yrs in corporate R&D. Just finished 2 yrs as a patent agent in a small IP boutique. Currently deciding whether to stay a patent agent (no intention of law school) or return to R&D before my tech skills get too out of date. Sound familiar? My take.
(a) You are a patent agent trying to decide whether to go to law school or return to engineering. From a financial perspective, there can be (and usually is) a big difference in compensation between an atty and agent. So don’t base your financial decisions on your current status as an agent. Also, in terms of growth potential, again, a huge difference. As an atty, you can do litigation, licensng, etc. As an agent, you can’t (other than assisting an atty). As an atty you can become a partner. As an agent, you can’t.
(b) I took a huge cut in $. But that was to be expected, since I went from an expert to a rookie. But at least I didn’t have to shell out $$ for law school. Unless I catch a lucky break (or game the system, see below), I’ll never get back to the same $ level as I had in R&D.
(c) The compensation structure in law firms is arcane. With different billable rates, flat rates, minimum billables, and bonuses...difficult to compare compensation. Unlike in engineering, bonuses can be a substantial part of your compensation. And it’s hard again to do a proper comparision. Sometimes, bonuses are non-linear: that is if you exceed your minimum hrs by 100 hrs, you get $X, but if you exceed it by 200 hrs, you get more than $X for the second 100 hrs.
(d) As a general rule, in any job, once you stay in the same position for more than ~ 5 yrs, your salary will start to saturate; certainly after 10 yrs, you’re flat except for inflation offsets. R&D seems to saturate more gradually than line or field engineers. So, if $ is your major concern, you’ll need to move to a managerial position anyway. Some corps have started a “dual-ladder” system so engineers can advance without shifting to management. But the numbers that are promoted along that track are very low. I was fortunate enough to be on that track. From what I can gather, the learning curve as a patent agent is nearly exponential. If you’re competent, you go from newbie to 90+% proficiency in 3 yrs. Which is why so many firms post a min of 3 yrs experience. By 5 yrs, you’ve reached 99+%, and you reach saturation. There’s further expertise with additional years, but incrementally small (as far as strictly patent prosecution is concerned). No additional opportunities without becoming an atty. Very general terms. Always exceptions.
(c) How to game the same system as a patent agent: Work for a firm that does a large volume of flat rate cases for large corps who file quasi-nonsensical cases just for bragging rights. The corps that say, “We are one of the most innovative corps in the world. Hey, we filed over a 1000 patent applications last year.” They are not overly concerned with quality, because the likelihood of any of the “inventions” amounting to anything marketable is near zero. The trick here is to get all the easy ones on your docket. So, as a rough example, assume you get $2500 flat rate/case. And assume that translates to 40 billable hrs. If you do in fact knock them off at one/wk, you make $10K/mo. Not too shabby. If you get real hard ones and take 80 hrs, you make $5K/mo. NOT good. BUT, if you get cinchy ones and crank them out at 20 hrs, you make a whopping $20K/mo. That’s a lot of bucks. So now the range is quite broad: $60K - $240K/yr...before bonuses on the high end (no bonus on the low end of course).
(d) Technical satisfaction is a different story, however. If you stick to patent prosecution (and not move on to litigation), life as an atty is the same as life as an agent. Once you get past the $ issues, your life as an agent will (very soon) tell you whether IP is right for you. Here, your experience as a practicing engineer may actually hurt you. Sounds strange. But true. The way to game the system is to do the rock bottom min work to get an acceptable application. That’s how you can crank them out. If you have been a practicing engineer, you tend to be more analytical, you try to understand the material, you try to get all the technical details correct. And that all takes time, and your clock keeps ticking away. On the other hand, if you got your degree in eng, decided you didn’t like it, and went straight to law school...you won’t likely get wrapped up in technical details (or won’t know enough to catch technical issues in the first place). Hence, you can crank out those suckers. You now have to decide if you can compromise your technical standards in order to make sufficient $.
(e) The usual disclaimer...there’s a wide range of situations, and blind luck is always a factor.
