Since 2014, the Supreme Court’s Alice decision has fundamentally reshaped how software patents are examined. If you need to overcome Alice 101 rejections in 2026, an application that merely claims an “AI-powered system” without grounding that claim in a specific technical mechanism will fail. If your patent application describes what your software does instead of how it technically improves computer functionality, you are handing the USPTO a straightforward basis for rejection. This guide explains what examiners look for and how to strengthen your claims accordingly.
At A Glance
Most software patents fail under Alice because they claim abstract ideas without tying them to a concrete technical improvement. To overcome Alice 101 rejections in 2026, software and AI patents must clearly show how the invention improves computer functionality, not just what it does. This requires specific architectures, data flows, and technical effects grounded in real computing problems.

Why Alice Still Haunts Software Patents
If you work with software, AI, or SaaS, you have likely encountered this sentence in a USPTO office action:
Claims are rejected under 35 U.S.C. §101 as being directed to an abstract idea.
That sentence is the modern signal that a software patent application has not adequately demonstrated a concrete technical contribution.
The root cause is the Supreme Court’s Alice Corp. v. CLS Bank (2014) decision, but the enforcement landscape has shifted considerably since then. Following the USPTO’s July 2024 AI Guidance, examiners are now drawing sharper distinctions between “generic” AI implementation and genuine technical improvement. Failing to navigate these standards remains the leading reason software and AI patent applications are rejected in the US today.
This is not just legal theory. A 2024 analysis of USPTO office-action data found that the agency’s AI-focused examination group, Technical Center 2120, included a Section 101 rejection in 77% of its office actions that year — more than double the rate recorded in 2022. (This figure is drawn from Voice of IP’s 2024 analysis of USPTO examination data; readers are encouraged to consult the primary data directly for their own research.) For AI and software practitioners, that single statistic illustrates why claim drafting around technical mechanics — rather than AI terminology — has become essential.
But here is an important nuance that many founders and developers miss: Alice did not eliminate software patents. It established a higher bar for vague ones.
This article explains, in plain language:

- What examiners now look for in 2026
- How to strengthen claims using concrete technical examples
- Practical strategies to respond to Section 101 rejections

Alice Corp. v. CLS Bank Summary
What the Case Was About
Alice claimed a system for reducing settlement risk using a computer as a neutral intermediary. The Supreme Court held that the core idea — using an intermediary to manage financial risk — was a fundamental and abstract concept, and that simply implementing it on a generic computer did not make it patentable. The decision established the two-step analytical framework that every software patent application must now pass.
The Two-Step Alice Test
Every software patent application is evaluated against this framework before eligibility can be confirmed:
Step 1: Is the claim directed to an abstract idea?
Examples of abstract ideas include:
- Mathematical calculations
- Organizing human activity
- Fundamental economic practices
- Mental processes
Step 2: If yes, does it include an “inventive concept”?
This means:
- Something significantly more than the abstract idea itself
- A real technical improvement, not merely the use of a generic computer to perform a conventional task
A claim that fails either step is very likely to be rejected under Section 101.
Hypothetical Practitioner Scenario: Consider an early-stage startup building a tool that flags potentially fraudulent transactions for banks. The founding team’s first claim draft describes “a system that uses machine learning to analyze transaction data and output a fraud risk score.” Running this through the two-step test, Step 1 would likely find the claim directed to an abstract idea, since spotting suspicious patterns in financial records is a mental process that fraud analysts and auditors have performed for decades, with or without a computer. At Step 2, generically invoking “machine learning” does not add anything “significantly more,” because the application does not specify any particular model architecture, training method, or data pipeline that differs from off-the-shelf techniques. The likely result is a Section 101 rejection echoing the same abstract-idea reasoning at issue in Alice itself. An attorney familiar with post-2024 examination practice would instead push the team to identify what their system actually does differently at the infrastructure level — for example, how features are extracted from raw transaction logs, how the model is retrained as fraud patterns shift, or how inference is distributed across nodes to reduce latency — and draft claims around that mechanism.
Examples of Abstract Ideas in Patent Law (2026 Reality)
Key takeaway:
What the software does matters less than how it does it.
Why Software Patents Fail Under Alice
1. Claims Focus on Results, Not Mechanisms
One of the most common drafting errors is writing claims that describe what the system achieves rather than how it achieves it at a technical level. Consider the contrast:
Weaker approach:
A system for detecting anomalies using AI.
Stronger approach:
A system that modifies feature vector dimensionality using adaptive hashing to reduce inference latency.
The second version specifies a concrete computational mechanism — adaptive hashing applied to feature vectors — and ties it to a measurable technical outcome: reduced inference latency. Examiners are trained to look for this kind of specificity. Claims that read like product descriptions rather than technical specifications are routinely rejected at Step 1 of the Alice analysis.
2. “AI” Is Treated as a Black Box
Following the USPTO’s July 2024 AI Guidance, examiners are instructed to treat AI models as conventional components unless the application demonstrates otherwise. The practical implication is that citing “a neural network” or “a machine learning model” in a claim carries little weight on its own — these are now considered off-the-shelf tools in the same way that “a processor” or “a database” would be.
A claim structured as:
Using a neural network to classify data
is highly likely to face a Section 101 rejection on these grounds. By contrast, a claim that specifies the architecture and its technical effect — such as:
Using a sparsity-constrained neural architecture that reduces memory access cycles by 42%
gives the examiner something concrete to evaluate: a specific architectural constraint with a quantified technical outcome. This is the kind of claim language that survives closer scrutiny under current examination practice.
3. No Technical Problem, No Technical Solution
Alice analysis requires that the claimed invention address a problem rooted in computing — not merely a business or operational inconvenience. Many patent applications frame their problem statement in business terms, such as faster approvals, better targeting, or improved accuracy. While these outcomes may be commercially meaningful, they do not, on their own, satisfy the Alice framework.
The specification and claims together need to articulate a problem that exists in the computer itself, and a solution that operates at that same technical level. Examples of problems that courts and examiners have recognized as genuinely computer-centric include:
- GPU memory thrashing during batch inference
- Packet loss in distributed systems under high concurrency
- Model drift caused by non-stationary training data
When the problem and solution are framed this way — in terms of what is happening inside the machine, not what a user experiences — the application is in a much stronger position to satisfy both steps of the Alice test.

Software Patent Eligibility in 2026: What Changed
Critical Update: July 2024 AI Guidance A significant shift occurred with the USPTO’s July 2024 Guidance on Patent Subject Matter Eligibility for AI Inventions, effective July 17, 2024 and published at 89 Fed. Reg. 58,128. This guidance explicitly clarifies that simply applying AI to a conventional task is not sufficient. To withstand scrutiny, claims must recite a specific technical improvement to the computer’s functionality — such as enhancing processing speed, reducing memory usage, or improving security — rather than using AI as a generic tool. The update also introduced three new Subject Matter Eligibility Examples (47–49) for AI inventions, indicating that a claim is more likely to demonstrate a “practical application” when it: (1) ties the AI concept to a particular field of use, (2) is supported by a specification that technically explains how the invention improves the underlying technology, and (3) recites non-abstract claim limitations — such as specific data transmission steps or real-time processing constraints — that actually implement that improvement.
USPTO Examiner Trends (Observed)
Based on post-2019 USPTO guidance and patterns observed in 2025–2026 office actions:
- Examiners rely heavily on Prong 2 of Step 1 when evaluating whether a claim is “directed to” an abstract idea
- “Practical application” language carries more weight than ever, but it must be grounded in the claim language itself — not only in the specification
- Technical effects must be explicit in the claims; reciting them only in the written description is generally insufficient to overcome a Section 101 rejection
These patterns align with broader appellate data. A 2025 review of Patent Trial and Appeal Board (PTAB) decisions found that the overall affirmance rate for Section 101 appeals in 2024 was 88.6% — meaning roughly seven out of eight examiner rejections on eligibility grounds were upheld on appeal. (This figure is cited from Patent Docs’ 2025 analysis of 2024 PTAB decisions; readers should consult the primary source for full context and methodology.) In practice, this means winning a Section 101 fight at the PTAB is the exception rather than the rule — which is why amending the claims themselves (Step 3, below) matters far more than arguing the existing language is correct.
The Recentive Analytics Precedent: AI’s First Federal Circuit Test
On April 18, 2025, the Federal Circuit issued its first precedential ruling applying the Alice framework directly to machine learning patents in Recentive Analytics, Inc. v. Fox Corp., 134 F.4th 1205 (Fed. Cir. 2025). Recentive had asserted four patents covering machine-learning-generated television scheduling and network maps against Fox. The court held that claims reciting nothing more than the application of an existing, generic machine learning technique to a new data environment are ineligible under Section 101, unless the claims also disclose a specific improvement to the machine learning model or process itself. The panel rejected the argument that performing a familiar task faster or more efficiently through conventional AI is, by itself, enough to confer eligibility.
Case Application: Suppose a logistics startup applies a standard, widely available gradient-boosted machine learning model to delivery route scheduling — a task dispatchers have long performed using spreadsheets and experience. Under Recentive, a claim that simply describes “a system that uses machine learning to generate optimized delivery routes” would likely face a Section 101 rejection for the same reason Recentive’s scheduling patents failed: it claims an existing AI technique applied to a new field of use, without describing any improvement to the technique itself. To align with post-Recentive examination practice, the application would instead need to claim the specific mechanism — for example, a new feature-encoding method, a training pipeline change that reduces convergence time, or a particular model architecture modification — rather than the mere fact that machine learning is being applied to logistics.
The U.S. Supreme Court declined to review the Federal Circuit’s decision in December 2025, leaving Recentive as binding precedent for AI and machine learning patent applications heading into 2026.
What Helps in 2026
- Explicit hardware interaction
- Resource optimization with measurable technical outcomes
- Improved data structures that address a defined computational problem
- Reduced computational complexity with supporting specification detail
- System-level architecture claims that go beyond functional description
⚠️ 2026 LLM Patent Trap: The “Prompt Engineering” Rejection
Based on Patent AI Lab’s review of post-2024 Section 101 rejection patterns in AI examination units, claiming a “system that uses prompt engineering to generate outputs from an LLM” is very likely to draw a Section 101 rejection under current examination practice. Examiners treat prompt writing itself as an abstract “mental process” — a pattern consistent with the elevated AI-unit rejection rate noted above and with the Federal Circuit’s 2025 holding in Recentive Analytics that applying an existing technique (such as an off-the-shelf LLM) to a new use case does not by itself create eligibility. To build stronger claims, applicants should describe the backend architecture in specific terms — for example, vector database indexing methods, dynamic context-window optimization approaches, or particular RAG (Retrieval-Augmented Generation) data pipeline configurations — rather than the use of prompting alone.
AI and Software Patent Eligibility: A Practical Example
While AI tools can accelerate the drafting process (see our PowerPatent Review for a detailed analysis), simply relying on their raw output often produces claims that are vulnerable to Section 101 rejections.
Example: Weaker Claim Formulation
“An AI system that generates code based on user prompts.”
This is highly likely to be treated as an abstract idea. The claim describes a result — code generation — without specifying any technical mechanism. Under current examination practice, an examiner would likely find no “inventive concept” that distinguishes this from conventional software behavior.
Stronger Formulation
“A code generation system that dynamically constrains token prediction using a syntax-state machine, reducing invalid compilation paths during inference.”
This version is technically grounded for several reasons:
- It identifies a specific technical problem: invalid compilation paths that waste processing cycles during inference
- It claims a concrete computational mechanism: a syntax-state machine that actively constrains the token prediction process
- It describes how the system operates, not merely what it produces

How to Overcome Alice 101 Rejections: Step-by-Step
Step 1: Identify the Abstract Idea Yourself Before the Examiner Does
Before responding to an office action — or better yet, before filing — it is worth applying the Alice test to your own claims. Ask whether the core of what you are claiming could be performed mentally, or whether it amounts to nothing more than data processing in the abstract. If an honest reading of the claim suggests that a trained analyst could accomplish the same task using pen and paper (or a spreadsheet), the claim is likely to be characterized as directed to a mental process or mathematical concept at Step 1. This self-diagnosis is not about being pessimistic; it is about understanding where the examiner’s analysis will start, so that the response can address that starting point directly rather than arguing past it.
Step 2: Reframe the Invention Around Its Technical Improvement
Once the abstract idea has been identified, the next step is to locate the genuine technical contribution in the specification and make it prominent in the claims. A useful drafting heuristic is to construct a sentence of the form: “The invention improves computer performance by [specific mechanism].” Common categories of technical improvement that have fared well under Alice analysis include reducing memory access overhead, minimizing unnecessary network calls, improving instruction-level parallelization, or lowering the computational cost of inference at the model architecture level. The key is that the improvement must be something that happens inside the computer system — not something that a user or business experiences as an outcome downstream of the computation.
Step 3: Amend the Claims — Arguments Alone Rarely Suffice
The PTAB affirmance data cited above (88.6% of Section 101 rejections upheld on appeal in 2024) makes a clear practical point: arguing that existing claim language is already eligible is a low-probability strategy. The more effective path, in the majority of cases, is to amend the claims to introduce the technical specificity that was missing. This means adding concrete system components — specific processors, memory architectures, or network interfaces — describing the data flow steps that implement the improvement, and including technical constraints that link the claimed mechanism to a measurable outcome. Amendments of this kind give both the examiner and, if necessary, the PTAB a clear basis for finding that the claim recites ‘significantly more’ than the identified abstract idea, which is the primary mechanism to overcome Alice 101 rejections.
Comparison: Weaker vs. Stronger Software Claims
Real-World Implications for Founders and Developers
- Patents with weak technical specificity create due diligence risk for investors
- Technically grounded patents are more defensible and carry greater valuation weight
- Claims that clearly articulate a technical improvement are better positioned to withstand both examination and post-grant challenges
- How claims are drafted at the outset directly affects enforcement leverage later
The cost of weak claim drafting is not just a rejected application — it is the time, filing fees, and strategic opportunity lost during prosecution.
It is also worth noting that patents are not the only available protection strategy. If an invention faces persistent eligibility challenges under Alice, a trade secret approach may be worth exploring in parallel. Our guide Is Your SaaS Code Safe? Copyright vs. Patent & Trade Secret Strategies covers that terrain in detail.
Future Outlook: Where Software Patents Are Heading
Expected trends:
- Higher bar for AI claims, particularly those applying existing techniques to new domains
- Greater examiner focus on system-level improvements and quantifiable technical outcomes
- Continued skepticism toward claims that treat AI as a black box
- Greater importance of technical metrics and benchmarking data in the specification
Strategic Reality:
Alice is not going away, and the Federal Circuit’s 2025 Recentive Analytics decision signals no appetite to soften it for AI. But the standard is now predictable: claim the technical mechanism, not the AI label, and support that claim with specification detail that explains how the mechanism produces a technical improvement.
Final Takeaway
Alice is not anti-software. It is a framework that rewards technical precision.
A patent application that is well-positioned under Alice generally does three things well: it identifies a problem that exists in the computer system itself, it claims a concrete mechanism that solves that problem at the technical level, and it describes the how rather than just the what. These are drafting disciplines, not legal mysteries. You can successfully overcome Alice 101 rejections if you invest the time to articulate your invention at the right level of technical specificity.

FAQs
Is software patentable after Alice?
Yes. Software is patentable if it improves computer functionality and is not just an abstract idea implemented on a computer. The key is demonstrating a concrete technical mechanism, not merely a desired outcome.
Are AI patents harder to get approved?
Generally, yes. Under current USPTO examination practice, AI techniques are treated as conventional unless the application clearly demonstrates a specific technical improvement to the model, architecture, or process — not just to the business result.
What is the most common Section 101 mistake?
Claiming outcomes instead of mechanisms. An application that describes what the system produces, rather than how the system technically achieves it, is highly likely to face an eligibility rejection under Alice.
Does AI-generated code affect patent eligibility?
No, not by itself. Eligibility depends on the technical contribution the invention makes, not on the method used to generate or draft the underlying code.
Can Section 101 rejections be appealed?
Yes, but the data suggests that amending the claims is more effective than appealing on the existing language. A 2025 review found that approximately 88.6% of Section 101 rejections were affirmed on PTAB appeal in 2024.
Does the Recentive Analytics decision affect AI patent applications?
Yes. In Recentive Analytics, Inc. v. Fox Corp., 134 F.4th 1205 (Fed. Cir. 2025), the Federal Circuit held that applying an existing machine learning technique to a new field of use is not sufficient for patent eligibility unless the claims also describe a specific improvement to the underlying model or process. The Supreme Court declined to review this decision in December 2025, making it binding precedent.
