Software Patent Eligibility Post-Alice USPTO 2026

In 2026, software patent eligibility sits at the intersection of clearer doctrine and higher expectations. In the US, the USPTO has tightened inventorship around human contribution while reminding examiners to recognize genuine computer-technology improvements. In Europe, the EPO continues to center eligibility on “technical character” for computer-implemented inventions (CII). If your product roadmap relies on algorithms, ML pipelines, or embedded software, the opportunity is real—but only if your claims are specific, technical, and grounded in measurable system improvements Source: USPTO MPEP §2106 Source: EPO Guidelines G‑II 3.6.

What Changed in 2025–2026

• US inventorship reset for AI-assisted inventions. On November 28, 2025, the USPTO issued Revised Inventorship Guidance for AI-Assisted Inventions, rescinding prior leniency and reaffirming that only natural persons can be inventors, applying traditional conception standards (e.g., Pannu). AI is treated as a tool; document the specific human contributions that materially contributed to conception Source: Federal Register (Nov. 2025 Guidance).

• Examiner emphasis on holistic, tech-focused eligibility. The August 4, 2025 Kim Memo reminded examiners to apply MPEP §2106 holistically for AI/software, recognizing improvements to computer functionality and raising the bar for §101 rejections that ignore claim specificity. This has nudged outcomes toward eligibility when claims detail concrete technical solutions Source: Kim Memo (Aug. 2025) Source: USPTO MPEP §2106.

• Eligibility signals from the top. In 2026, Director-level actions, including overturning a PTAB AI ineligibility decision and signing AI/crypto patents, telegraph a pro-eligibility posture for claims that recite specific, technology-improving features (still, generic “apply ML to data” claims remain vulnerable).

• Case law pressure on generic AI. The Federal Circuit’s Recentive Analytics decision (April 2025) affirmed early §101 ineligibility for generic machine-learning claims lacking a concrete technical improvement—reinforcing that specificity in architecture, data structures, and system-level effects is pivotal.

• Faster search, steady fees. Patent Center’s AI-assisted tools are accelerating search and prosecution for digital inventions, with a meaningful share of AI-related filings now in the pipeline. No material fee changes were flagged for 2025–2026; rely on the USPTO fee schedule for current amounts Source: USPTO Patent Center Source: USPTO Fee Schedule.

• EPO alignment around technical effect. The EPO’s 2026 work plan prioritizes consistent practices for CII and AI, focusing examiners on technical character and effects (e.g., hardware efficiency, improved resource allocation), keeping the EPO’s long-standing “technical solution to a technical problem” approach stable and predictable Source: EPO Guidelines G‑II 3.6 Source: EPO 2026 Work Programme.

Bottom line for 2026: in both the US and EU, software patent eligibility turns on whether your claims describe a specific, technical improvement to computer functionality or another field of technology—and whether you can show exactly what the humans invented.

Software Patent Eligibility Frameworks, Step by Step

US: Section 101, Alice/Mayo, and Human Inventorship

• Statutory baseline. Under 35 U.S.C. § 101, claims directed to laws of nature, natural phenomena, or abstract ideas are not patentable unless the claim elements, considered as an ordered combination, amount to “significantly more.” The USPTO’s MPEP §2106 operationalizes the two-step Alice/Mayo analysis:

- Step 1 (judicial exception): Is the claim directed to an abstract idea (e.g., certain methods of organizing human activity, mathematical relationships, or mental processes)?

- Step 2 (integration): Do the claim elements integrate the exception into a practical application—e.g., a specific improvement in computer functionality, a specific data structure that improves performance, or a constrained algorithmic architecture that yields a technical benefit? Source: USPTO MPEP §2106

• Examiner playbook in 2026. Examiners are cued to evaluate claims holistically and give weight to concrete technical improvements and specific architectures, consistent with Federal Circuit patterns (e.g., claims like McRO’s that recite particular technological solutions fare better than generic, results-oriented claims). The Kim Memo reinforces this approach for AI/software claims Source: Kim Memo (Aug. 2025).

• Inventorship for AI-assisted inventions. Following the November 2025 guidance, only natural persons can be inventors. Applicants should identify the human’s material contributions to conception—e.g., identifying the problem, designing model architectures, specifying feature engineering pipelines, crafting training regimens, or defining data structures—and document those contributions in filings and inventor declarations Source: Federal Register (Nov. 2025 Guidance).

EU: CII at the EPO—Technical Character and Technical Effect

• Statutory baseline. Under EPC Art. 52(2)(c), programs for computers “as such” are excluded. However, computer-implemented inventions are patent-eligible when the claimed subject matter has technical character and contributes to a technical solution to a technical problem—often demonstrated by technical effects like reduced memory usage, improved processor throughput, enhanced security hardening, or improved control of an industrial process Source: EPO Guidelines G‑II 3.6.

• 2026 consistency drive. The EPO’s 2026 work plan emphasizes aligned practices for CII and AI, reinforcing a predictable, technical-effect-focused pathway for software claims. The more your claim ties algorithmic structure to measurable system-level improvements, the stronger your CII position Source: EPO 2026 Work Programme.

• Claim drafting posture

- Emphasize how the software interacts with hardware, data structures, sensors/actuators, or network components to deliver measurable technical gains (e.g., memory footprint reduction by X%, latency improvement by Y ms).

US–EU Comparison at a Glance

Common Pitfalls That Sink Software Patent Eligibility

• Abstract, results-only claims. Reciting “apply machine learning to data” without specifying model architecture, training regimen, data structures, or system-level performance gains invites §101/Art. 52 rejections.

• Mental-process framing. If examiners can analogize the steps to human mental activity or pen-and-paper analysis, Step 2 integration fails.

• Thin technical narrative. Failing to tie algorithmic details to tangible improvements in memory, latency, throughput, security, or control systems undermines eligibility on both sides of the Atlantic.

• Misaligned inventorship. For AI-assisted inventions, omitting documentation of the natural person’s specific conception contributions risks inventorship challenges under the 2025 guidance.

• Ignoring holistic analysis. Overlooking the Kim Memo’s holistic evaluation can depress success rates—claims that read generically, even if novel, are less likely to clear §101.

• Late, vague prosecution. Delayed or non-specific responses to §101/Art. 52 objections (e.g., no comparative performance data, no system diagrams) prolong prosecution and reduce leverage.

• Fee and deadline drift. Missing the 12-month provisional-to-non-provisional conversion, 3-month OA response window (or paid extensions), or 2-month appeal deadlines derails rights.

Strategic Recommendations for 2026 Filings

1. Lead with the technical improvement. In the specification and independent claims, explicitly state what computer-functionality improvement you achieve (e.g., 30% reduction in memory due to a compressed index; 20 ms latency reduction via pipelined inference). Map claim elements to that improvement.

1. Claim with specificity.

- US: Constrain the algorithmic architecture (e.g., model topology, feature extractors, quantization scheme, cache-aware data layout) and how it interacts with computing resources, to satisfy “significantly more.”

- EU: Highlight technical character—tie claim features to a technical effect per G‑II 3.6 (e.g., improved CPU cache utilization, fault-tolerant consensus for network nodes).

1. Draft multi-layered claims. Use system, method, and computer-readable-medium claims. Include dependent claims that lock in concrete data structures, pipeline stages, scheduler policies, and hardware interactions.

1. Document human inventorship. For AI-assisted R&D, maintain contemporaneous records: problem framing, architectural design choices, prompt engineering rationales, training/validation protocols, and decisions that materially contributed to conception. Align inventor declarations with the 2025 guidance.

1. Front-load evidence. Include comparative benchmarks, ablation results, or architectural diagrams in the specification. These support eligibility (technical improvement), non-obviousness, and smoother examiner interviews.

1. Prepare examiner interviews early. Use them to agree on the improvement story under MPEP §2106 and to identify surgical amendments that convert abstract language into grounded, technical recitations.

1. Use the PCT to stage global rights. File early under the PCT to lock priority, then tailor claims for US “significantly more” and EPO “technical effect” upon national/regional phase entry at 30/31 months. This gives time to generate data and refine claim sets for CII scrutiny Source: WIPO PCT Guide.

1. Leverage digital tools. Use Patent Center’s AI-assisted search and document tagging to tighten prior art positioning and streamline prosecution Source: USPTO Patent Center.

1. Audit your portfolio. Reassess pending and issued claims: post-2025 examiner posture favors concrete, architecture-specific claims. Consider continuation filings to capture improvements, and EPO divisionals to pursue alternative technical effects.

1. Budget with discipline. Anchor planning on the USPTO and EPO fee pages. For US small entities, expect around $456 for core non-provisional filing/search/exam (per brief). For the EPO, use the fee calculator; Euro-PCT entry commonly aggregates around €2,570 before attorney/translation costs Source: USPTO Fee Schedule Source: EPO Fee Calculator.

Putting It All Together: What Makes Software Patentable in 2026?

• In the US, software patent eligibility hinges on clearing Alice/Mayo by anchoring claims in a specific technical improvement to computer functionality or another technology domain. Holistic examiner review and 2025–2026 signals favor inventions that detail architecture, data handling, and resource-level effects—backed by evidence and precise claim language Source: USPTO MPEP §2106 Source: Kim Memo (Aug. 2025).

• At the EPO, patentable software inventions (CII) require technical character with a credible technical effect. Claims should avoid “program as such” territory by showing how the software produces hardware/network/processing improvements consistent with the Guidelines Source: EPO Guidelines G‑II 3.6 Source: EPO 2026 Work Programme.

• Cross-border strategy: Draft once, localize twice. Start from a common, improvement-centric spec; then tailor claims to US “significantly more” and EPO “technical effect,” using the PCT to preserve optionality Source: WIPO PCT Guide.
