There remain traps for cranks who anthropomorphize AI (don't try to list it as an inventor!), but otherwise this guidance leaves room for the courts to assess invention where AI tools are involved. A key factor will surely be the injection of human agency at some point in the inventive process. 2/2

Al systems, including generative AI and other computational models, are instruments used by human inventors. They are analogous to laboratory equipment, computer software, research databases, or any other tool that assists in the inventive process. As the case law establishes, inventors may "use the services, ideas, and aid of others" without those sources becoming co-inventors. l The same principle applies to Al systems: they may provide services and generate ideas, but they remain tools used by the human inventor who conceived the claimed invention. When one natural person is involved in creating an invention with the assistance of Al, the inquiry is whether that person conceived the invention under the traditional conception standard set forth above in Section III.

Here's the crux of the PTO's new official guidance, out today, on AI and inventorship. It seems...fairly innocuous. 1/2 public-inspection.federalregister.gov/2025-21457.p...

The Real History of Tenure If academics want to protect the idea of tenure, they need to understand how and why it became the norm.

"Attacks on academia are fundamentally about remaking the labor practices that define higher education."

They could have done something like this in the Trump immunity case and given a chance for the special counsel to take Trump's federal election subversion charges to trial.

Expediting cases is a choice

Just a reminder of my favorite idea for a law student note: Pick an important Supreme Court case from 5-10 years ago, and see how lower courts are interpreting it. It's helpful for practitioners and courts, and something law students can research and present effectively.

Coming to America is a strange experience for someone with a complex racial, religious, ethnic and national background. These many identities get subsumed under a racial or national identity that is then hyphenated with America.

That was a serious lapse. You trusted me with your writing and time, and I responded with something that wasn't fully honest or earned. I'm sorry for that. I completely understand if this shook your trust, and if you want to step back from this.

Generative AI in the Law School Classroom – Jeremy Sheff

Last month there were allegations that some of my students may have used generative AI on my final exam. The incident led me to give some serious thought to how we are dealing with these tools in the professional education context. Here’s what I wrote to my students: jeremysheff.com/2025/06/02/g...

Neat study. I get that the copyright issues you address are keyed to pending litigation, but the hard question to my mind is how findings like this should influence our understanding of what "copying" (rather than substantial similarity) means with respect to LLM outputs.

1. A must-read thread. I'll highlight three more problems with this opinion, which is the only case to prevent people from using a class action to challenge US government renditions to El Salvador. I often write about complex litigation, with a focus on class actions involving government bodies.
