I have the chance to move from my engineering career (full-stack robotics, software engineering, cloud background) to assist a law firm as a patent agent in my respective fields. Has anyone made this transition who can offer some input on how that transition played out and what they learned?
FWIW: IAAL and I also have a CS educational background but never really worked as an engineer outside of academia. I spent a few years in the middle of my legal career working primarily on patent prosecution, which is the work also done by patent agents.
I would personally not recommend patent prosecution to any lawyer or aspiring lawyer. Patent prosecutors hold a second class status within the legal profession, something I only realized when I started working in that area. The work is inherently challenging (in a bad way) in a typical law firm context resulting largely from the fact that it is generally fixed-fee work (with those fees generally having been driven down over a long period of time) in a context where lawyers have nominal billable hour expectations. You are under pressure to churn out patent applications in a relatively short period of time. I believe this is one of the main reasons for problems in patent quality seen particularly in the software space over the past two decades. The work itself is highly non-intellectual in nature.
Maybe the considerations are different for a patent agent who doesn't intend to go to law school. Some firms will pay for patent agents to go to law school part time which could be beneficial if the patent agent were to graduate and go into some other specialty (but I suspect that hardly ever happens).
Edit to add a related point: For anyone with a scientific or engineering background who goes to law school, I recommend resisting the temptation to take the USPTO's patent bar exam (this exam is also incidentally something patent agents take). It might seem to be a useful credential, but by becoming a registered patent attorney, you will get pigeonholed into a patent prosecution practice group within a law firm, which is problematic for the reasons I give above.
From my observations, I think patent litigation is pretty high up on the legal totem pole. Patent lawyers who focus on actual litigation (through federal district courts, as opposed to the USPTO PTAB (Patent Trial and Appeal Board) are responsible for cases that have legal fees at the $10M-level. But to support your point, a trial attorney who focuses on patent litigation is not necessarily a patent lawyer (though can be). There is a sort of arbitration at the PTAB for patent disputes, which does require a USPTO-registered attorney, but that's a process that is cheaper for all parties involved, so it's less money for the law firm. I assume those lawyers have less prestige at larger firms.
From my experience, patent lawyers who focus on patent prosecution bill at rate ~$300 - $500; patent litigators are $500 - $1000 (and I'm sure some litigators are much higher).
Agreed. For those who don't know, the term "patent prosecution" is US legal industry jargon referring to the process of applying for and obtaining a patent. The term is used as a shorthand to refer to a common specialty area that focuses on that kind of work and certain related non-litigation matters. Patent prosecution specialists sometimes also get involved in litigation but typically in a secondary or supporting role. This to some degree reflects the two-class system I referred to. From personal experience and anecdote it is common for patent prosecution specialists to seek to get involved in litigation because, essentially, it is "easier to make your hours" as I remember one colleague putting it, but often opportunities are limited because of the unofficial two-class system that exists.
Patent litigation is an important sub-area of litigation work and practitioners in that area are not especially likely to have STEM backgrounds (unlike patent prosecution specialists) and are not expected to be USPTO-registered. You can see evidence of the two-class system in the academic backgrounds of the lawyers involved -- patent prosecution specialists are more likely to have attended less prestigious law schools than the patent litigation specialists at a given firm. It's my sense that outside the US the equivalent of patent prosecution lawyers are typically not members of the legal profession and often work in small firms focused entirely on patent and trademark procurement grunt work.
This is accurate. Patent litigation is at the top and pulls the most fees by far.
Of course, it can also be very challenging. Setting aside troll/NPE cases, you're sometimes competing against the best attorneys at the best firms in the country, in cases where the amounts of revenue at stake vastly exceed any amount that the attorneys could reasonably bill (even at the typical rates of $500-$1500/hr).
My dad told me a story once about being paid for expert witnessing for patent expertise.
The short version was that some company's legal team was looking to hire him for expert witnessing. They knew who he was, and had a rough idea of his opinion already, and knew that he was more or less opposed to their position. So he asked them why they'd be willing to pay $?!?/hr for him to read stuff and tell them that he thought they were wrong.
They basically told him "if paying you $?!?!? allows us some insight into the opposition's potential strategy that lets us file a motion that just delays a ruling from morning until after noon recess, that will recoup all the costs we pay you". And apparently they weren't even exaggerating because in half a day they pulled over an order of magnitude more than $?!?!? in sales.
Evidently this sort of paying experts who disagree with you to help form your case strategy is just a normal thing, and it makes sense to me, I just couldn't fathom the numbers at the time. The amount of money specifically in drug patent cases is staggering. There is a long, long list of drugs that pull in over a billion dollars a year in sales.
The US's total (legal) drug market is like half a trillion dollars.
Don’t discount the nice side effect that when you hire the opposing parties’ best possible expert, they are then precluded from working for the other side.
I went from being a biomedical engineer -> M&A lawyer -> software engineer with a side legal practice.
I learned that law school was intellectually rewarding and the practice of law can be fun, but I could not stop thinking about software that I wanted to build to improve the practice of law. I took that as a sign that I needed to spend some of my working life being a software engineer.
I think what I have now is a great balance. A stable job as an engineer, with a law practice where I only take on clients that are nice to work with.
What was your route towards biomedical engineer? That’s the route that I find most interesting right now - especially as I’m getting older. Seeing lots of family in ill health and lots of new medical info we’re getting from then pandemic
> What was your route towards biomedical engineer?
These days you can do an undergrad or masters level specialization in biomed, but that hasn't been true for very long. People make there way their from all sorts of paths, including (pretty often) mid-career moves.
One thing that impacts it is you are typically working in a regulated industry, so it's easier to make the change if you have some experience in this. This can be more of a jump for people in software who may haven never seen formal engineering practices. This sounds scarier/more annoying than it is (or at least, than it has to be)
Contrary to some comments here, pay wise it seems to mostly be pretty middle of the pack. Nobody that I know of is going head-to-head with FAANG for "pure" software roles, but overall seems comparable to similar jobs.
haha yea but I have a feeling it will change in the future as the boomers age. I've looked at Bioinformatics and Genomics. Looks like a way easier route for software devs to get into the field and the pay I constantly read is that it's so low!
I see that a lot, and as a former biomedical engineer I would like to reframe this a bit.
Regardless of field of study in college, be it engineering, humanities, science, etc, you learn valuable skills that are almost certainly applicable to beyond your field of study. I for one saw many of my peers enter software engineering roles, project manager roles, or even consulting roles that all pay well, likely 80-100k+ right out of college. Speaking to my siblings who graduated a year ago, they appear to concur, and many are being paid more. Could this be a factor of where you go to college? Perhaps, but I'd argue it's also a bit about selling yourself to wherever you are trying to go.
Additionally, there are many folks that obtain further specialization in a different area of study via a graduate degree, such as a PhD like you mentioned, but also Master's level degrees. They can do biomedical engineering in undergrad, pursue other engineering master's, and succeed in their desired career. I found many peers that pursued this route especially for computer science.
To further push against the thought that biomedical engineers are without opportunity: The US Bureau of Labor Statistics states the mean annual wage of biomedical engineers is around $98,000, and the growth projections are around 6% over the next ten years, while lower than the average of 8%, is not "bad".
Would certainly like to see any other anecdotes from other biomedical engineers to refute or support my statements above; I'm no longer an engineer and thus my insight is likely limited compared to currently employed engineers.
What was your road into software engineering? I’m a lawyer now, and make pretty good money, but I can’t quit the thoughts of how much better legal tech could make it. So I’ve found myself interested in software but not wanting to drop my pay…at least for too long.
My office mate and good friend of many years is a patent agent. He was/is industrial/electronic/radio but then pursued patent agent 100% for a while.
Ultimately he came back to tech, but acts as a sort of front line patent agent for our company as well.
We have many discussions about the inanity of the whole system. I’m an idealist, he’s more of a realist about it. It exists. If nothing else, we participate from a defensive posture.
He has shared that he kind of likes the game of patents. You have an idea, which you then have to represent/express/model in a language that looks like English but isn’t exactly that has its own set of rules and idioms. Or in short, it can be seen a lot like the software we write. While he likes it as a sort of variety, he seems to like it about 20%, and when the workload goes above that much commitment, the complaining starts and the desire to get back to “the real work we do” begins to be expressed.
When I have asked him why he doesn’t do more of it, he has shared the same observation others have shared here: Agent is a great skill to have to broaden your value, attorney is what you want to do if you want to earn lots of money at it.
On that note, we both observe that the foundation of lawyering is to be in contention with someone, and generally speaking the less contention among people, the better. Someone’s gotta do it apparently, but it’s not a sphere of happiness.
Insightful post. I like the way you describe the intellectual attraction of prosecuting patents. I am not sure I understand your point about disputes being the foundation of lawyering but not patent law specifically. Patent litigation is rife, more so than in some adjacent fields (contract, privacy etc.) Most areas of law have both non-contentious and contentious aspects.
Ultimately, he went to law school because he didn't feel there was career growth as just a patent agent... you've got to be a full-on attorney if you want growth in that marketplace.
I'm recalling a little bit of his rationale, but it seems that if you're curious about the law, it's a decent way to get exposure without the total commitment of law school, and you get paid while you're learning. But don't think of it as a "career transition" unless you're going totally into the law, it's more like an experiment to see if that's a direction you'd want to take. You'd still have to go to law school and pass the bar if you want to make a career out of it.
I would agree that the real money is always in being a lawyer.
Also if you have web development & SEO skills, legal marketing is stupidly lucrative and you need to be a lawyer to actually take advantage of co-counsel fees. You could advertise personal injury on the side and outsource your case qualifying to a few big firms and just collect money by selling leads.
(I worked at a law firm doing exactly this for 3 years)
Any sources you recommend for learning more about legal marketing?
I remember reading about Cellino and Barnes and their use of TV ads and found that fascinating so would be interesting to learn more about the current state of affairs.
I don't really know that there's much written about it. Lawyers tend to keep business models close to their chest and it was very much a learn by doing kind of thing.
When I took the job there was certainly a period of "mind blown" while I learned more and more about the industry but I had the perfect position to learn the industry.
For online advertising, all of the core skills about keyword bidding and targeting apply. Terrestrial marketing is vastly more effective in the legal space though and while more expensive (TV), billboard and radio/podcast pricing has come down significantly.
Really it's all about coming up with your own effective price model and making sure you can measure the effectiveness of your campaigns. Most law firms are vastly overspending compared to what they actually need to but they're spending in places that bring in so much money that they can literally throw money away at this. If you're data driven you can make a fortune here and there's tons of existing firms (and a small but growing group of marketing consultancies) to partner with if needed.
Having technical skills and a JD will make people want to work/partner with you.
I went from electrical engineering (logic design and then aerospace) and went to law school (night school) specifically for patent law. I now have 14 years as a patent attorney writing patents. It is definitely a change of pace from designing circuits to a largely technical writing career.
However, (with a small "boutique" firm) the hours are more flexible, the work is rewarding due to always learning new technology at the bleeding edge, and you get to interact with engineers/developers in the industry. Having a strong engineering/science background helps you in getting up to speed on new technology quickly, and having a strong writing background is a required skillset (but that can be developed over time). As with many careers, having good mentor(s) does make a difference. The "lawyer" part is definitely present, but more in the background for drafting/obtaining patents (referred to as "prosecution") vs. litigation work. For prosecution, "the law" is more about learning a set of "operating rules" and applying those rules to your daily work to both comply with the requirements and to anticipate litigation issues in the future. Patent work can also encompass licensing, employment agreements, trademarks, portfolio strategy, competitor analysis - all of which vary from firm to firm on how deeply that sort of work crops up. For litigation, you are definitely more involved in traditional attorney work, sometimes courtroom work/sometimes behind the scenes.
To become a patent agent, passing the Patent Bar Exam is required, and takes a bit of studying - it is not trivial and largely learning a set of rules/procedures to practice in the field. Of course, adding the "attorney" title requires yet another more comprehensive Bar Exam (state-by-state) and most states also require attending a law school prior.
I think it really depends on which part of the industry you are working on, the stuff you describe matches my experience as an "inventor". I think there are two patent industries now:
One is writing patents for new, novel, and interesting things and doing all the other things you describe.
The other is churning out crappy patents as quickly as possible and flooding the patent office with whatever will stick.
What are your thoughts about the "two tier system" others are mentioning? I haven't heard of that before, but it seems like doing prosecution is not desirable? Some law firms offer to pay for your law school, so it doesn't seem bad doing prosecution while you attend law school, but I have no idea. The opportunity I was proposed is in patent prosecution, but it seems people transition into something else quite frequently.
If by two-tier, you refer to the prosecution (i.e. drafting) vs. litigation (i.e. lawsuit) tiers, there is a clear separation in the industry. I do prosecution exclusively, and can't answer if it is inherently desirable (inasmuch as any career path is desirable), but I don't find litigation appealing. On the litigation side of the world, you might find a faster-paced, higher-stressed, higher-compensated environment which has more significant deadlines and "stakes" especially when involved in court proceedings. However, I would also imagine that a more flexible career path is tied to such work since litigation can translate broadly to other lawyerly endeavors vs. the more specialized prosecution.
But, to stress again, the work is inherently different on prosecution vs. litigation. Prosecution also has its work deadlines, but these can be managed more flexibly in practice. Prosecution is a joy for someone like me who prefers to largely work independently (once you learn your craft sufficiently), attempt a good work-life balance, learn new tech every day, apply that knowledge to writing about it in a very specialized manner, compartmentalize tasks (each patent can have its own mental silo), and still do some limited "lawyerly" work dealing with examiners at patent office to attempt to get patents allowed in light of the prior art. Plus, depending on the firm and your ambition, you can branch into anything - litigation, licensing, contracts, etc.
I should note that you don't need to pass the patent bar exam to do litigation, but you would eventually need that for prosecution (agent, attorney). So some say that it can be harder to switch from litigation to prosecution because of that barrier.
I started to - I went to law school with the intent of switching, and ultimately cut that short to go back to tech. I just didn't enjoy working with attorneys. I'm sure some people do, so my rejection of that industry should be taken with a grain of salt... but I'd take time to get to know who your professional community would be before committing to such a change.
I'm curious. What was your experience working with attorneys? I heard an anecdote from a law student that the classmates were highly competitive about grades. Less anecdotally, there was a recent Financial Times article about corporate lawyers at one firm billing ~100 hours each week, and others sleeping only ~5 hours a night. It also reported a more accurate measurement from a survey:
"That level of exhaustion is taking a toll. In a survey of over 1,700 lawyers published in September, LawCare — a mental health charity in the sector — found almost 70 per cent had experienced ill health, either clinically or self-diagnosed, in the 12 months to January 2021, including depression and anxiety. According to the study, those aged between 26 and 35 were displaying the highest burnout scores — in part because of a lack of autonomy over their working lives. A fifth of respondents said they felt unable to cope." [0]
I'm guessing that law attracts competitive personalities who are willing to work long hours to make money, and that prospect might cause many lawyers to be high-strung.
It’s like anything else, people get into law and chase money without thinking about what they are getting into and why the pay is so high. Don’t feel sorry for them, a bunch of type-a types killing each other for sport is by it’s nature a stressful endeavor.
Even in public sector, the mental toll of dealing with criminal prosecution and defense is high. Alcoholism is rampant, all sorts of personal acting out / implosions are frequent. (High-flyer prosecutors and corp counsel people in local government are looking for money indirectly through political aspirations or access.)
It’s the price of admission to working your way into a more elite strata of society. It’s much harder than the old fashioned way.
People who find a less lucrative, but sustainable, niche are like any other professional.
Though: Software Engineering is not doing all that well on the mental health front either, as far as professions go. See [1] which I found kind of shocking, though I don't know what those numbers look like for other professions or in the general population.
Software Engineering is an appealing profession for people with several of the issues on this list (in particular: social anxiety, ADHD, spectrum disorders) so this is not surprising.
You are mixing up cause and effect; working as a developer is not causing ADHD, bi-polar disorder or spectrum disorders.
I’m a truly happy attorney! So is my wife. But it’s a client service job. I think a lot of Americans suffer from delusions of grandeur, especially more highly educated ones, and the reality of being a cog in the machine really bursts their bubble. I think of myself more like a very skilled tradesman. People need legal representation, just like they need electricians. My trade is intellectually stimulating and highly remunerative, so why shouldn’t I be happy?
Word of caution. UC Davis computer science graduates could not do patent law when I wanted to. Why? Because the dean Norman S. Matloff didn't fill out the paper work. So - "computer science" wasn't considered an engineering field at the time. It gets worse, I was the only one to make the request EVER. Make sure you research if your computer science department would be considered a valid engineering bachelors under the patent law offices. You may be able to talk to the dean to spend the time and get it done.
Yes. If you want to practice patent prosecution you need to pass the patent bar, and the patent bar is only available to a narrow and kind of weird set of engineering degrees.
Only some computer science degrees count, and only some degrees with "engineering" in the title count. The patent office is usually very strict with this and is not interested in hearing about why your degree should count.
They do offer alternative methods of qualifying based on the specific numbers of credits you have in certain classes, but that too is fairly strict.
+ extremely independent
+ lots of reading about different subjects
+ less time working on tooling or “chores”
+ admin to manage your calendar
- much higher productivity expectations than tech
- high intensity
- varied knowledge of attorneys
How useful, and how common, would a PhD in life sciences (biology/biochemistry/genetics/etc.) to become a patent agent? I anecdotally heard and read of a few people who struggled to find industry work with that degree, and were then recommended to try and become patent agents/attorneys as the PhD should allegedly give them an advantage in work applications.
From what I observed back when I was working at IP-specialty firms, it's pretty common and a credential that would be sought after. I think in the life sciences area, if you wanted to get into patent agent work and didn't have a PhD it might be difficult to get a position. By contrast, in other technical fields having a PhD is relatively uncommon among patent agents. I don't know to what degree my highly negative view of patent prosecution work carries over to the life sciences area, although I believe the "two class system" exists there as well.
Know someone with PhD in chemistry that went into to law, then onto patent law. It seemed a long road. Then it took awhile to become accepted. However, here we are 15-20 years later, and they work as much as want to work. Interesting, is that they are registered (holds bar?) In a few States and countries.
I'm in the process of attempting this. I'm taking some classes at law school, but I'm only studying towards the Bachelor of Laws, not towards the kind of university credential that you need as a prerequisite for being allowed to sit the bar exam to become a real lawyer. I'm instead using it as an opportunity to try to find ways of combining tech knowledge and legal knowledge and getting interesting work out of it that draws on both but doesn't require a bar exam.
I think there are some interesting avenues opening up there, around Legal Tech and also around the general fact that I expect that tech will become more compliance-driven in the future.
I mean: When I started out in the field, it was pretty much this unregulated wild west. When I retire, I expect that working in a tech company will feel a lot like working in a bank does today. In a bank, lawyers and law-savvy managers are hugely influential, because everyone else struggles to navigate all the nuance of the regulation that affects them, and it's not even just about money, but about potentially going to jail or not.
My dad did a transition from Mech E to patent lawyer, but super early in his career. Basically to the point where he didn't work much professionally as a mechanical engineer. My understanding is it's very different, but he really likes patent law. It requires a much greater interest in digging through legal history, and an even greater emphasis on writing than engineering does.
From my perspective (working as an engineer, growing up hearing everything about patent law):
If you like the building stuff part, stick with engineering.
If you like the debugging / analysis / almost-audit-like side of tech, and aren't scared by a giant reel of red tape (and as mentioned before like history digging and writing), then maybe patent law would be for you.
If you get good enough, you may be able to affect changes in the red tape even.
I can't really say much about the patent agent side.
a friend of mine went from working in oil extraction field engineering to being a patent agent. he does a lot of reviewing applications, finding prior art, and analysis of the inventions.
it’s interesting to him since he is always coming across curious inventions and applications but otherwise it seems like a pretty dead end career. he is particularly unambitious so i think the lack of pressure other than “review this stuff” is pretty nice for him.
I wouldn’t trade being a builder to be a paper pusher.
When was in the pharma field I worked with a patent agent who had an M.D. and a PhD. She was outstanding -- really made a huge difference to the quality of our patents. She worked for one of the major law firms.
However I can confirm what others have written: she was at the bottom of the hierarchy. They treated her as if she were a paralegal.
This wasn't about her specifically -- we had a bunch of partners and associates working on our thicket of IP over the years: men and women from all sorts of national and social backgrounds. Despite her extensive education they considered her skills as simply mechanical.
PS: they charged as much for her time as a junior associate. I doubt she got paid as much though.
As far as made-up "bullshit jobs" go in this society, patent lawyers are likely well-positioned on the compensation scale, but if you enjoy actually building something and having some fruit of your labor to show at the end of the day, it might not be a good place for an engineer.
You'll be "solving" a problem that is the result of a completely artificial and particularly badly designed system. Such jobs can get to you as you curse the stupidity of the people who came up with and run that system daily.
That said - as long as nothing changes - someone has to do the job.
I don't think I could personally make it as a lawyer in any capacity; from those I have talked to in the legal profession it seems like 100% pushing papers around.
Also, I don't agree with patents in a political sense.
It's not mindless "pushing papers around" -- that job is done by paralegals and administrative assistants.
But 50-100% of most attorneys' time is spent either "reading things," "researching things," or "writing things," if that is what you mean. That is the bread and butter of legal work these days, whether it's writing briefs, e-mails, letters or something else, and reading legal opinions, research materials, discovery, etc.
Basically most of your job as a patent litigator is to read things and occasionally depose people, then research things, then write things (not always in that order). The remainder of time is mostly spent on client communications and marketing.
Occasionally you may make it to trial or a mock trial, where you spend a lot more time on your feet and speaking (or sitting and listening while someone else speaks), but still generally around 25-50%+ of your trial time is spent reading and writing.
Its pretty mindless, even the "reading" and "researching" is extremely dull. The level of logical complexity isn't that great and its a lot of overworded nonsense.
The body of knowledge in law is vast and some areas can be intellectually stimulating as well (depending on one's interests). "Overworded nonsense" that you usually see (in contracts or legislation, I suppose) happens when less than stellar lawyers are made to write stuff upon a deadline, and is the equivalent of "spaghetti code". Usually, it's fine since nobody (I think) gives you a bonus for succinct writing when drafting a contract. But you might get in trouble for missing some "edge cases". There's also a lot of cargo culting (magic Latin incantations) and building on questionable templates (technical debt). Sometimes people intentionally write in weird illegible ways to impress people (think Perl one liners).
Anyway, when most programmers see an unfamiliar codebase for the first time, they'd probably think most of the code are "overworded nonsense" until they fully understand the "business requirements" and the special cases implemented. (This is where the adage against complete rewrites comes from.) Unless you're really an expert in the area of law, you're probably not qualified to say that some legal texts are overworded nonsense.
But yeah, there's more parallels in law and software engineering than one might think. I'm a software engineer by trade, not a lawyer, but I do have a degree in law, and I often read up on cases or occasionally do my own legal research mostly for fun and personal interest. I would contend your "extremely dull" claim. TBH I might read more legal texts than Other People's Code, the latter which I generally hate doing, and is usually more boring for me (and occasionally infuriating when I know the coders spewing writing crap instead of putting effort in making the stuff succinct and clean).
My friend group is about 60% lawyers, so I have a reasonable sense of what I'm talking about. I think a lot of software is also over-worded nonsense, and I try very hard to make sure I don't work in a place where that's encouraged. But the issue is that the law is the law and the over-worded nonsense is inescapable and very much encouraged. Now you can say only lawyers are allowed to say that, but a lot of lawyers will say that (in private anyway, not if you're paying them). A lot of the complexity comes down to the fact that its very hard to change the law. I understand your parallels with a piece of software, now imagine a piece of software built slowly over 100s of years by programmers with very divergent motivations, and which required massive amounts of consensus to make changes to. Oh and no automated testing or types or any mathematical correctness built in anywhere, which is actually the stuff that makes software elegant and powerful. That would be one truly horrific piece of software, and imo thats what legal code is.
It depends on what you are doing. Legal research and writing can be anywhere from kind of dull to fascinating. That's also true for pretty much any job, so I'm not sure what your point is.
I agree with the others who say that being a patent agent is kind of a dead end job unless you want to go be an attorney.
Even patent attorneys who do prosecution, however, are in for kind of a grind. Again as others mentioned, it's often either fixed-fee or low-billable-rate work, and the client often won't know the difference between a really great patent and a mediocre one.
To me the real fun is in patent litigation, where you sue or defend lawsuits in federal court. That is where the rubber hits the road and patents are really tested. To get a job there, you mainly need a law degree from a good or great school and excellent grades, although a tech background (or a background as a patent agent) can help.
I came very close do doing this in the early 2000's. Though my degree was in Electrical Engineering, my professional career has been all software. (Full disclosure: I was actually a double major, but was a semester shy of finishing CS and finishing EE meant I had to graduate).
As others have noted, your degree will determine whether you can actually sit for the patent bar and be a registered patent agent. Certain degrees or showing equivalent level of training are required.
geofcline's comment covers the high level differences (+ extremely independent + lots of reading about different subjects + less time working on tooling or “chores” + admin to manage your calendar - much higher productivity expectations than tech - high intensity - varied knowledge of attorneys) so I'm going to talk about the part of the process I know about.
When I applied to college, I couldn't decide between Engineering and Law. I ended up going with Engineering, but 5 years into my career it was time to change jobs, so I figured I might as well try the law route. The path I chose was to become a Technology Specialist (or similarly worded role) at a big law firm.
A Technology Specialist was someone with an Engineering degrees who helped the actual patent attorneys evaluate and draft patents. The law firm would pay a salary (only about 5% than my Engineering salary at the time) and would both pay for law school and guarantee you a job after school. At the time, starting attorney salary was about 50% more than my current salary, so that was quite a deal.
I sent out 5 resumes, got 3 interviews, and one job offer. I joined a firm and was one of about 25 Technology Specialists. Here's where it got interesting. I was very unique in that I had a) actual experience b) a degree that wasn't biology or chemistry and c) the only one with _only_ a master's degree. Every other "tech spec" was a PhD that noped out of post-doc life of long hours and low pay for long hours and high pay. I later found out that CS/EE types were a harder sell because they typically had to take a pay cut to join.
While I saw some cool and innovative tech, and got to meet some names that anyone in tech at the time would know, I saw just as much bogus business process and software patent work. I had a beautiful office with city views and an amazing secretary (patent secretary itself is a skilled, well-paying role), and billed out at $250/hour. The job itself was fairly boring, though. I worked mostly by myself and was creating nothing. After a year I went back to tech and joined a startup.
FWIW, the life of an attorney doing patent prosecution seemed much more chill than those doing litigation. I think part of the reason is that there are only so many people with advanced engineering degrees required to be understand and write patents who also want to be lawyers. For myself, I showed up at 7am to take a couple hours to study for the LSAT, and I generally stayed until 5:30pm to take advantage of free dinner in the cafeteria. The office (and this was early 2000's, so not a ton of WFH tech) was generally empty before 9 and after 6.
In my role as researcher and engineer, I've engaged with a lot of corporate lawyers in the patent process. The best interactions I've had have been with those that transitioned to their role from engineering.
I would personally not recommend patent prosecution to any lawyer or aspiring lawyer. Patent prosecutors hold a second class status within the legal profession, something I only realized when I started working in that area. The work is inherently challenging (in a bad way) in a typical law firm context resulting largely from the fact that it is generally fixed-fee work (with those fees generally having been driven down over a long period of time) in a context where lawyers have nominal billable hour expectations. You are under pressure to churn out patent applications in a relatively short period of time. I believe this is one of the main reasons for problems in patent quality seen particularly in the software space over the past two decades. The work itself is highly non-intellectual in nature.
Maybe the considerations are different for a patent agent who doesn't intend to go to law school. Some firms will pay for patent agents to go to law school part time which could be beneficial if the patent agent were to graduate and go into some other specialty (but I suspect that hardly ever happens).
Edit to add a related point: For anyone with a scientific or engineering background who goes to law school, I recommend resisting the temptation to take the USPTO's patent bar exam (this exam is also incidentally something patent agents take). It might seem to be a useful credential, but by becoming a registered patent attorney, you will get pigeonholed into a patent prosecution practice group within a law firm, which is problematic for the reasons I give above.
