The countdown has started. When Isomorphic Labs' first AI-designed drug clears Phase 1 and files for FDA approval, it will hit a wall no algorithm has mapped: patent law requires a human inventor, the FDA has never approved a drug where AI was named as author or inventor, and no court has resolved the question. That reckoning just moved closer. Max Jaderberg, President of the DeepMind spinoff, told the WIRED Health stage in London on April 16 that Isomorphic is entering human trials for AI-designed drugs — an oncology and immunology pipeline the company has been building toward since its 2021 founding, with $600 million from Thrive Capital and GV, Alphabet's backing, and pharmaceutical partnerships with Eli Lilly and Novartis worth nearly $3 billion. The announcement did not name a drug, a trial, or a timeline. The silence is what makes it interesting.
What Isomorphic has said publicly is specific enough to matter. Its drug-design engine, IsoDDE, more than doubles AlphaFold 3 accuracy on protein-ligand binding predictions, according to benchmarks the company published in its technical report. AlphaFold itself — the model that earned Demis Hassabis and John Jumper the 2024 Nobel Prize in Chemistry — is now used by more than 2 million researchers across 190 countries. Jaderberg's pitch was that AI-designed molecules can be engineered for higher potency, letting patients take lower doses with fewer side effects. Whether those benchmarks hold in human biology is the question Isomorphic just volunteered to answer.
The competitive position is not in dispute. Isomorphic is the best-capitalized AI-drug-design outfit in the world, the most directly plugged into the model infrastructure that won a Nobel Prize, and now the first to move candidates into clinical testing. If it succeeds, Alphabet becomes the compute layer of pharmaceutical R&D. If it fails, the correction in AI-biotech valuations will be loud. The graveyard of drug discovery — twelve to fifteen years, $2 billion or more, roughly a one-in-ten chance of approval once a compound enters Phase 1 — is well documented. Computational design changes the attrition curve in theory. Human biology has been known to disagree with elegant theories.
What Isomorphic has not addressed is the intellectual property question that its clinical move now forces into focus. The legal status of AI-designed drugs is genuinely unsettled. The USPTO's revised inventorship guidance, issued in November 2025, maintains that conception — the formation of a definite and permanent idea of the complete invention — requires a human mind. The Federal Circuit has confirmed that an inventor must be a natural person under the Patent Act. No regulatory body in any jurisdiction has approved a drug where AI was listed as inventor, according to agency statements and multiple confirmed sources. When a molecule proposed by a model reaches the approval gate, the question of who owns it has no settled answer.
Isomorphic has not said publicly how it plans to handle inventorship on its pipeline compounds. It will have to eventually. The molecule will have a name, a trial number, and endpoints. The patent filing will have an inventor — or a legal dispute about why it does not. That is the story the announcement starts, not the one it tells.
What Jaderberg actually said at WIRED Health, verbatim: "We are gearing up to go into the clinic. It is going to be a very exciting moment as we go into clinical trials and start seeing the efficacy of these molecules." The excitement is earned. The skepticism is also earned. The molecules involved will eventually have names. When they do, we will know whether five years and Alphabet's money bought something real or just a very expensive preview.
Until then: watch.
