What can the claims of 9,600 asserted patents from the last five years tell us about building stronger portfolios? This post uncovers surprising claim drafting patterns across industries and kicks off a short series using real litigation outcomes, not intuition, to shape portfolios from the patent up.
I analyzed 9,700 asserted patents from 6,500 litigations over the last five years and compared them to a control set of 10,000 randomly selected granted patents from the same period. Here's the insights I found most interesting:
As I reflect on 2025, I think about the 2 characters that changed my entire mental model of the world: O3. Released only 8 months ago, O3 is OpenAI’s first reasoning model that can produce genuinely useful legal work. ArcPrime's features, from claim charts to continuation recommendations, only work because of reasoning models. They are what give folks “tingles” on the future of the profession.
The worst thing about patents is the SLOW feedback loop. The field doesn’t evolve quickly, bad policies and inefficiencies linger, and there’s almost no room for real experimentation. You can file something today and not learn whether it mattered until long after everyone involved has changed jobs.
Building a patent portfolio is more political than people think. The obvious answer, "patent what's valuable", is not so straightforward.
When I first got to Facebook, I was dying to know how the world’s top companies actually used patents. Up to that point, all I knew was how to write and obtain high-quality ones — the craft, not the strategy.
I'm ecstatic to share that ArcPrime has raised $5.1M 🎉 in combined seed and preseed funding, led by early Datadog-backer RTP Global and Rackhouse Venture Capital, with participation from Leonis Capital, Atria Ventures, and leaders from NVIDIA, Meta Superintelligence, Apple, and Braze.
This year, most of our team met in Chongqing, China — the multi-level cyberpunk city. In Chongqing, uptown and downtown describe altitude, not direction. We surrounded ourselves with neon lights one day and raging waterfalls in Wulong Karst the next.
People tend to overcomplicate patent strategy. But it’s really simple: nobody pushes around the person with the biggest gun.
Most advice is a Rorschach test - it means different things to different people. Take the classic: “Do one thing well.”
Great to see everyone at IPO! It was a great experience meeting new folks from all over the industry. We did 2 things:
I've seen thousands of continuation recommendations. Our AI-generated recommendation beats all of them.
Most companies don’t know which of their patents are the best. And how could they? To find out, you’d normally need outside counsel to build claim charts costing 5 or 6 figures.
Super proud of the team for what has been a monstrous July! I'm most excited about patent charts and product charts. I've long wondered how to identify the most valuable patents in a portfolio at scale. Traditionally, folks used analytics such as number of forward citations, among a few other factors. While this is useful, and we are shipping this in August, the better proxy of value is if you can find live products in the marketplace using your patents.
Most ideas aren’t obviously great. But they’re also not obviously bad. They exist in this uncomfortable middle ground. This is where companies make their worst patent filing decisions.
A partner at a law firm once looked at something I wrote and scolded, “Do you know how to write a paragraph?” I thought I was better than average given I passed the bar and did well in some college writing courses. Apparently not. I had to relearn the basics: use topic sentences and break ideas into digestible pieces.
Many attorneys are hoarders. They'd pay any fee to keep a case alive until the bitter end. Ask them why and you'll hear the same thing: "Just in case!" or "But I've spent so much money on it!" Are these strategies or habits?
We’ve grown faster than expected since launching almost two months ago! There’s real hunger for 1) AI-powered workflows that make teams more efficient and 2) a modern take on IP software.
Slightly hot take: It's a great time to be a specialist. I used to think generalists had the edge. David Epstein's Range convinced me that breadth beats depth. I even switched from patent counsel to product counsel, hoping that exposure to different legal domains as a 'mini-GC' would make me a better attorney.
If you're looking for an easy 10% performance boost, minimize the friction of getting your thoughts to an LLM. Install the desktop app, learn the shortcut, or keep the tab open - whatever gets you feedback faster.
When choosing outside counsel, pay attention to the associates. As a former associate, I learned that they don't just support the process; they critically shape it.
The first time I saw true craftsmanship was at Fish & Richardson. Seeing Hans Troesch's work was like seeing a new primary color. Hans is a once-in-a-generation craftsman who redefined "excellence" for me.
Hello, world. I've been lurking for 20 years. But the problems that excite me now won’t let me stay there.
