On July 14, 2026, the Senate Judiciary Committee held a full committee hearing titled “From Genes to Machines: the Patent Eligibility Debate." The same week, the IP Policy Institute published the first large-scale empirical study of AI patent invalidation rates — and the numbers are bad. AI patents face Section 101 challenges at 23.6% of litigated cases, versus 11.9% for non-AI patents, across 14,000 patents litigated between 2000 and 2025. Part of our Builder’s Log.
The hearing, the data, and a pending bipartisan bill called the Patent Eligibility Restoration Act (PERA) together mark a potential inflection point in US AI patent law. Whether PERA passes or not, builders who are generating novel AI systems — inference architectures, training methods, evaluation pipelines, agent frameworks — need to understand what the law permits today and how to protect work before the rules change.
The Problem: AI Patents Are Dying in Court Twice as Fast
The IP Policy Institute study, published July 13 and authored by Professor Amy Semet of the University at Buffalo School of Law, draws on 14,000 AI patents litigated from 2000 through 2025. The finding that stands out: AI patents are not failing because they are obvious or not novel. They are failing because they are abstract.
Section 101 of the patent code defines what is eligible for patent protection. The Supreme Court’s 2014 decision in Alice Corp. v. CLS Bank established a two-step test for software and AI patents:
- Is the claim directed to an abstract idea, law of nature, or natural phenomenon?
- If so, does the claim add an inventive concept that amounts to “significantly more” than the abstract idea?
The Semet study found that AI patents face lower obviousness challenge rates than non-AI patents — the technology is generally recognized as novel — but are invalidated at double the rate under Section 101 abstraction analysis. The “double hurdle” is real: AI inventions are harder to keep alive, and harder to enforce even when granted.
In April 2025, the Federal Circuit tightened this further in Recentive Analytics, Inc. v. Fox Corp. The court held that applying established machine learning techniques to a new data environment — without reciting a specific improvement to the underlying ML process — does not satisfy Section 101. The novelty of the application is not enough. The ML method itself must improve. Recentive has since petitioned the Supreme Court for certiorari (filed October 2025); as of this writing the Court has not acted on the petition, so the Federal Circuit’s holding remains controlling law.
USPTO rejection rates in AI-related Technology Center 2120 (which examines AI and simulation-modeling applications) now include a Section 101 rejection in approximately 77% of office actions, according to Voice of IP’s analysis of USPTO examination data — roughly double the rate from 2022.
The Settled Law: AI Cannot Be Named as Inventor
Before addressing what AI inventions can be patented, the threshold question: can AI be listed as the inventor?
No. In August 2022, the Federal Circuit decided Thaler v. Vidal, holding that the Patent Act requires inventors to be human beings. Computer scientist Stephen Thaler had filed applications naming his AI system DABUS as the sole inventor. The court rejected this unanimously, relying on the Patent Act’s use of “himself” and “herself” — not “itself” — to describe inventors.
The Supreme Court declined to hear an appeal in April 2023. Thaler is binding precedent.
This matters practically: if an AI system generates the core idea with minimal human direction, the patent may have no valid inventor to name, rendering it invalid from the start.
What Can Be Patented Today
The Alice/Mayo framework does not make AI patents impossible. It makes them harder. The key is whether the claim improves a technical system or merely uses AI to automate something humans already did.
Strongest candidates:
- AI systems that improve computer functionality — memory management, CPU efficiency, latency reduction, throughput improvements with measurable benchmarks
- Medical diagnostics using ML with concrete technical application — biomarker detection, imaging analysis with accuracy improvements
- Novel ML architectures solving specific technical constraints — new training methods, hardware-software co-optimization, inference efficiency on constrained hardware
- AI controlling industrial or physical processes — manufacturing optimization, predictive maintenance, quality control with sensor integration
High-risk territory:
- Generic ML applied to a new dataset without improving the ML method
- Business methods that use AI to automate existing workflows
- Pure algorithm claims without connection to hardware or measurable technical effect
- Recommendation systems that apply standard techniques to new domains (Recentive Analytics territory)
The practical line: AI that makes computers work better survives Section 101. AI that merely computerizes something abstract does not.
The Human Contribution Requirement
Even when a patent is technically eligible, the inventorship question creates risk. The USPTO’s February 2024 guidance (since superseded, see below) applied the Pannu factors to AI-assisted inventions: a human inventor must have contributed in some significant manner to the conception, made a non-insignificant qualitative contribution, and done more than explain well-known concepts.
A November 2025 revision withdrew that approach entirely. The USPTO’s reasoning, as reported by IPWatchdog: Pannu is a joint-inventorship test, and it doesn’t apply when only one human is involved with an AI tool, because an AI system isn’t a legal person and so there’s no joint-inventorship question to analyze. The new guidance states plainly that “the same legal standard for determining inventorship applies to all inventions, regardless of whether AI systems were used in the inventive process” — no separate AI-specific test. The practical effect is the same ordinary conception standard used for any invention, which increases uncertainty in the short term as practitioners and examiners work out how it applies to AI-assisted work.
What qualifies as sufficient human contribution:
- Defining the technical problem the AI should solve, including constraints
- Selecting and tuning model architecture and hyperparameters
- Recognizing the significance of the AI’s output
- Validating results against technical benchmarks
- Making the technical judgment about which outputs to implement and why
What does not qualify:
- Prompting a general-purpose AI and submitting its output
- Using an off-the-shelf tool without technical direction
- Providing training data without inventive judgment
The builder implication: an engineer who instructs Claude to generate a novel attention mechanism, validates it against throughput benchmarks, and modifies the architecture based on that evaluation is likely a valid inventor. An engineer who asks ChatGPT to “write me a recommendation algorithm” and files the output is not.
The Legislative Bet: Patent Eligibility Restoration Act
PERA — S. 1546 in the 119th Congress, sponsored by Senators Tillis (R-NC) and Coons (D-DE) — is designed to undo Alice/Mayo. The bill would eliminate the judicial exceptions to Section 101 and replace them with five specific statutory exclusions: unmodified human genes and unmodified natural material, and a narrowly defined set of abstract-idea categories (mathematical formulas not embedded in an invention, processes a human could perform, and pure mental processes).
Under PERA, AI inventions, diagnostic methods, gene editing technologies, and software innovations would be explicitly patentable if the other conditions (novelty, non-obviousness, written description) are met.
The July 14 hearing was the first time the full Judiciary Committee — not just its IP subcommittee — took up PERA, a deliberation step toward a potential committee markup. Witnesses split evenly: former USPTO Director Andrei Iancu and patient-advocate Sue Peschin testified in favor, while CCIA’s J. John Lee and pathologist Dr. Debra Leonard testified against. The case supporters make: AI breakthroughs can be patented in Europe and China, but not in the United States. Foundational AI methods are being kept as trade secrets rather than disclosed through patents, depriving the public of the knowledge.
The case opponents make: PERA could revive the vague business method patents that proliferated before Alice and expose retail, financial, and service businesses to a new wave of patent assertion litigation — an argument retail industry groups have raised in earlier PERA proceedings and that CCIA’s J. John Lee echoed at the July 14 hearing, warning that PERA’s undefined terms could “generate new litigation and uncertainty rather than resolve it."
Status as of July 14: no committee markup date set. The bill has been reintroduced multiple times — this is its fourth introduction — without passing.
The International Gap
The US is now the most restrictive major jurisdiction for AI patent eligibility.
European Patent Office: Requires “technical character” — the AI invention must solve a technical problem through technical means; the EPO’s 2026 Guidelines for Examination confirm that a claim directed to a method using technical means (e.g., a computer) or to a device has technical character as a whole and is not excluded from patentability merely for involving AI or machine learning. This is generally regarded as more permissive than the current US Alice/Mayo standard. Separately, the 2026 Guidelines also added, for the first time, a dedicated foreword section on examiners’ own use of AI tools during examination — a different topic from patent-eligibility of AI inventions.
United Kingdom: On February 11, 2026, the UK Supreme Court decided Emotional Perception AI Ltd v Comptroller General of Patents, overturning the Court of Appeal and abandoning the decades-old Aerotel test in favor of the EPO’s “any hardware” approach. AI patent applications rejected under the old UK test may now be grantable. The UK is actively becoming more AI-patent-friendly.
China: The most permissive major jurisdiction. China issued nearly four times as many AI patents annually as the US by 2023 (183,302 vs. 48,197), and a Chinese government report put China’s share of global AI patents at 60% as of late 2025. For generative AI specifically, China filed more than 38,000 patents between 2014 and 2023 — roughly six for every one filed in the US, per WIPO’s Patent Landscape Report. The Chinese strategy: dense, narrow, application-specific filings that create operational cost barriers for competitors.
The citation differential: one analysis of 2024 AI patent data found US patents cited roughly seven times more frequently than Chinese patents on average (13.18 vs. 1.90 average citations), suggesting US innovations have greater technical influence per patent. But in terms of market coverage and legal barriers, China’s lead is substantial.
What Builders Should Do Right Now
1. Document human contribution at the time of invention, not retroactively. Timestamps in version control, dated technical notes, email chains showing decision rationale — these establish the human invention record contemporaneously, which is much harder to challenge than retroactive documentation.
2. Focus patents on what survives Alice today. If your AI system improves computer performance — faster inference, lower memory footprint, reduced latency — those claims have strong survival odds. If your system applies standard ML to a new domain, patent protection is legally uncertain regardless of PERA’s passage.
3. Treat foundational methods as trade secrets for now. If you have a novel training method that does not clearly improve computer performance (under current law), a trade secret may offer more durable protection than a patent that could be invalidated in litigation. This calculus changes if PERA passes.
4. File provisionals for novel architectures. A provisional application establishes a priority date with minimal cost and gives you twelve months to decide whether to pursue a full application. If PERA passes in that window, the priority date is set before the law changes. If it does not pass, you can let the provisional expire.
5. Watch the markup calendar. A committee markup on PERA will be publicly scheduled at least a week in advance. That is the signal that a floor vote is plausible. Change your filing strategy when you see a markup date set, not after the law passes.
6. Consider non-US filings for AI methods. For core innovations that fail Alice, an EPO or UK filing may be viable today. China filings for market access are separate from the quality/influence calculus — file there if you need market coverage, not because you expect citation impact.
Bottom Line
The July 14 Senate hearing is a step toward potential patent reform, not a change in the law. Today, AI patents are invalidated at twice the rate of non-AI patents, the Alice/Mayo framework remains binding, AI cannot be listed as inventor, and the November 2025 USPTO guidance revision has created new uncertainty around what level of human contribution is sufficient. PERA would change the eligibility rules significantly, but it has not passed despite multiple sessions of introduction.
For builders, the practical answer is: patent what clearly survives Alice today (computer performance improvements), document human contribution contemporaneously for everything, use trade secrets for foundational methods that fail Alice, and file provisionals to hold priority dates if you expect PERA to change the calculus within the next twelve months.
