Patent software powered by AI has gone from novelty to necessity. Patent professionals across law firms and corporate IP departments now rely on these AI tools to speed up the patent drafting process, catch errors, and produce quality patents at scale. The current generation uses generative AI and machine learning algorithms. They can handle everything from invention disclosure intake to full application drafting as well as office action responses, litigation support and portfolio analysis.
At Solve Intelligence, we work with over 700 IP teams and speak to patent attorneys daily about the tools they use and evaluate. This guide compares the eight leading patent drafting tools in 2026.
This comparison is built from company websites, press releases, and product documentation, along with funding and certification data from sources including Crunchbase and PitchBook. It also draws on direct conversations with patent attorneys and IP teams.
Solve Intelligence is included as one of the platforms reviewed. If you notice anything inaccurate or out of date, please contact us so we can correct it.
Solve Intelligence covers every major stage of the patent lifecycle on one platform, ranking as the top IP platform in a 2026 survey of 130 leading law firms. That scope shows in how the platform is used. Over 700 IP teams across six continents use this patent drafting software for application drafting, office action responses, continuations, divisionals, invention harvesting, and claim charting. Total funding stands at $55M following a $40M Series B.
Solve Intelligence's Charts product, launched in December 2025, handles litigation, invalidity, FTO, SEP, infringement, and portfolio mapping.
Released in February 2026 (and extended to Prosecution in March 2026), Solve Review introduced structured, customizable AI-powered patent review against jurisdictional frameworks (including the MPEP and EPO Guidelines), internal style rules, and firm-specific drafting standards. Solve Assistant was introduced in June 2026, allowing complex workflows to be executed from a single chat interface.

DeepIP (originally launched as davinci in 2024) has grown into a patent drafting software platform covering invention harvesting, patentability assessment, drafting, prosecution, and portfolio strategy. The main feature is native Microsoft Word integration: the generative AI assistant sits inside Word as a sidebar, so patent attorneys can stay in their usual drafting environment.
A web-based patent drafting software platform, Patlytics covers application drafting, claim charting, invalidity analysis, FTO, infringement detection, and portfolio management, suiting firms whose work extends beyond patent preparation and prosecution into enforcement or licensing.
Patent Bots is built around automated proofreading and USPTO examiner statistics: grant rates, examiner objections data, and prosecution timelines. In early 2026, it rolled out three new generative AI features: Gen AI Chat for Drafting, Gen AI Prompts (for improving consistency across drafts), and Gen AI Review.
Word add-ins for patent work aren't new. ClaimMaster has run one for over a decade, catching filing errors that slip past manual review. It runs locally, which fits firms that prefer on-premise software. The 2026 release brought major LLM capabilities to the +Drafting tier, including GPT-5 and Claude integration via a chat interface. IP professionals use it to double check patent applications for term usage issues, antecedent basis problems, and dozens of other common errors.
Evan Zimmerman (JD, UC Berkeley) and Len Boyette (early Okta engineer) founded Edge, a Y Combinator-backed platform that runs in the browser using keyboard commands and an in-line AI assistant for claim generation, descriptions, backgrounds, and disclosure parsing. The figure editor lets patent attorneys produce technical drawings and diagrams without external draftspeople. Edge is built to reduce time on repetitive drafting tasks.
Rather than application drafting, Black Hills AI focuses on the prosecution process, docketing automation, renewals, and paralegal task automation. Its AI platform (Otto IP) uses "Guided Skills": pre-built, attorney-designed workflows for generating OA response shells, claims, and amendments. The company was founded by IP attorneys with over 30 years of collective experience. For law firms handling high-volume prosecution, it helps automate repetitive tasks.
Most AI patent drafting tools on this list run on chat-based prompts. Patentext (launched early 2025) takes a different approach, building a visual "Invention Graph" from a detailed invention disclosure (notes, papers, transcripts, drawings) that maps components, steps, relationships, and variants. Each section of the patent application is then generated from that graph. The founding team has over a decade of drafting experience, including work at Fenwick & West and for companies like Uber and Airbnb.
AI patent drafting tools use artificial intelligence, natural language processing, and machine learning to speed up patent creation. Here's how AI patent drafting works in practice: these tools can handle disclosure intake, claim generation, specification drafting, figure creation, and document review.
Today's patent drafting software does more than generate text. The best generative AI models are now part of every advanced patent drafting tool on the market. They pull in legal requirements from each patent office (i.e., USPTO, EPO, JPO, PCT) and match user-specific preferences like firm-specific style and boilerplate language. The USPTO has issued its own guidance on how AI fits into that framework.
Many can also suggest alternative definitions for technical terms to help broaden claim coverage. These AI models are trained on large datasets of published patent applications, prior art, and office actions to produce first drafts that meet jurisdictional standards.
That said, these tools assist patent professionals rather than replacing them. Professional judgment remains central to strategy, patent claim scope, and the final work product.
Some patent drafting software handles the drafting process only. Others extend into patent prosecution, claim charting, or invention harvesting. Think about which stages of the lifecycle matter to your practice.
Drafting software patents is different from chemistry or life sciences work. Make sure the tool handles chemical structures, sequence listings, or figure generation for your practice area. To learn more, read insights from our IPWatchdog Webinar on AI in life sciences patent practice.
Patent preparation involves highly sensitive information. Look for SOC 2 Type II certification, encryption, and clear policies on data retention. AI generated content should never be used to train underlying AI models.
Some tools require an enterprise sales process; others publish transparent pricing or offer free trials.
The AI patent drafting landscape looks very different in 2026 compared to a year ago. Established platforms have expanded, and new entrants have arrived. The right choice comes down to your practice. If you need full lifecycle coverage, an all-in-one platform makes sense. If you have a specific pain point (proofreading, prosecution automation, figure-heavy drafting), a purpose-built tool may fit better.
At Solve Intelligence, we build AI-powered patent software for every stage of the patenting process, with patent attorneys always at the helm. Our Patent Copilot™ spans drafting, filing, patent prosecution, office action analysis, claim charting, infringement analysis, and invention harvesting.

It depends on what you need. For end-to-end patent drafting and prosecution, Solve Intelligence has the broadest feature set on this list. Other tools here are built around narrower parts of the workflow, from Word-native drafting to proofreading to litigation support.
Yes. AI tools like Solve Intelligence can generate complete application drafts from invention disclosures. These first drafts still require attorney review, editing, and strategic refinement as technical content should always be verified by a qualified practitioner.
Pricing varies across the market. Some tools offer free trials and published pricing, while enterprise platforms like Solve Intelligence typically require a demo.
Yes. Patent offices evaluate patent applications on their technical and legal content, not the tool used to draft them. The USPTO has issued guidance on AI use in patent practice, making clear that practitioners remain responsible for accuracy and completeness. All AI generated content should be reviewed before submission.
Cloud-based platforms like Solve Intelligence hold SOC 2 Type II and ISO 27001 certifications, process data sent to third-party AI providers under zero data retention agreements, and never use customer data for model training. Always verify a tool's data security posture before uploading sensitive invention disclosures.
Some tools (including Solve Intelligence) handle chemical structures (including Markush structures), biological sequences, and experimental data. Other tools vary; check with each vendor for your specific domain.
Drafting tools help create patent applications: claims, specifications, abstracts, and figures. Prosecution tools help respond to office actions, generate claim amendments, cite case law, and manage the prosecution process with examiners. Many platforms now cover both.
No. AI patent software supports attorney expertise rather than replacing it. These tools handle repetitive tasks so attorneys can focus on strategy, claim scope, and legal arguments. The attorney remains responsible for every word in the final filing.
