The LLM Sandbox gives you secure access to frontier AI models with every patent-specific tool and optimization you need—without the upsells, without the restrictions, without someone else deciding how you should practice law. One flexible platform. One simple pricing model. Unlimited possibilities.
Polished interfaces can't hide fundamental design flaws
Other platforms build constrained tools that oversimplify patent work. Instead of forcing you into our predetermined process, we build open-ended tools you can adapt to your needs. Your expertise should drive the tool—not the other way around.
Three core capabilities that handle the full spectrum of patent work
Section-by-section drafting with AI that learns your exact writing style. Upload examples of your work, and the system matches your voice—delivering work product indistinguishable from manual drafting.
Comprehensive analysis and response generation for 101, 102, 103, and 112 rejections. Create custom workflows or use agent mode for autonomous execution—you control the process.
Direct API access to patent databases and complete file histories. Natural language search retrieves any document—no manual downloads, no PDF extraction errors.
Stop choosing between speed and quality. The LLM Sandbox drafts patent applications 2-3x faster while maintaining complete authorship—you steer at every stage, reviewing and refining each section before moving forward. Upload your example applications, and the system learns your exact voice using section-aware style learning that understands Backgrounds should sound like backgrounds, not claim language.
Save 3-6 hours per Office Action with systematic, iterative analysis that eliminates eye strain. The LLM Sandbox gives you "reading superpowers"—analyze hundreds of pages in seconds, test amendment hypotheses against your application and cited references, and generate complete responses in your writing style. You maintain strategic control while the system handles time-consuming document review.
Stop wrestling with clunky interfaces and arcane API syntax. The LLM Sandbox gives you instant access to USPTO and EPO databases using plain English queries—no downloading, no re-uploading, no OCR errors. Search for prior art, retrieve complete prosecution histories, or find your own applications for style guidance, then send everything directly to your analysis workflow. What used to take 20-65 minutes now takes 3-6 minutes.
Transform claims, descriptions, or rough sketches into professional, editable Visio diagrams. The LLM Sandbox generates flowcharts, block diagrams, and technical schematics with proper reference numbering, USPTO-compliant margins, and professional formatting.
The LLM Sandbox integrates directly with Microsoft Word on both Windows and Mac, bringing AI-powered drafting capabilities into your favorite word editor. Draft, edit, and refine patent applications and office action responses without leaving Word.
Build your own multi-step processes or use agent mode for autonomous execution
Analyze prior art references, identify technical distinctions between your claims and cited art, develop amendment strategies that preserve claim scope, and draft complete responses with properly formatted amendments and persuasive remarks—all in your writing style.
Break down examiner's Alice/Mayo analysis, compare your claims against 140+ USPTO eligibility examples to find analogous eligible inventions, develop amendments emphasizing practical applications, and generate complete responses with MPEP citations and persuasive arguments.
For straightforward tasks following established patterns, use agent mode to execute entire workflows autonomously. Give it a high-level task and it breaks it down into logical steps, accesses relevant documents, and delivers comprehensive output—with complete transparency into its process.
Create your own multi-step processes for any repetitive task in your practice. Check for problematic language, generate claim variations, respond to specific rejection types, or anything else you do regularly. Save and reuse across cases, or share with your team.

Make changes directly in your Word document using track changes, rather than generating text in a side pane. Perfect for dispersed modifications, template population, and global document updates.
"For each claim element, add one or two sentences of additional description within the detailed description in paragraphs which relate to that claim element."
Track changes applied directly to your document
Deploy interactive chatbots for inventor engagement
Deploy interactive, context-aware chatbots for autonomous inventor engagement. Transform any custom prompt into a standalone chatbot with password protection and automatic transcription.
Conduct invention disclosure meetings asynchronously—chatbot autonomously generates questions, draws out technical details, and produces a complete transcript ready for drafting.
Built-in access to 140+ USPTO subject matter eligibility examples, complete MPEP, and Patent Cooperation Treaty resources. Query these authoritative sources conversationally with automatic citations.
Build persuasive arguments grounded in official guidance without manually searching through hundreds of pages of documentation. The system finds relevant sections and provides exact citations automatically.
Query authoritative sources conversationally
Watch real-world examples of how the LLM Sandbox transforms patent practice
Watch how the LLM Sandbox helps you overcome 101 rejections using analysis grounded in the USPTO's own subject matter eligibility guidance.
As patent practitioners ourselves, we understand confidentiality isn't optional—it's fundamental. The LLM Sandbox is built from the ground up with security as the primary design constraint.
Most AI tools work like a train—you get on and end up wherever it takes you. The LLM Sandbox works like a car—you control exactly where you're going. You make strategic decisions at every stage while the AI handles time-consuming execution.
Draft entire detailed descriptions in minutes instead of hours. Review thousands of pages of prior art with a single prompt. The LLM Sandbox gives you "reading superpowers" that dramatically reduce repetitive analysis and eye strain.
Upload 1-4 example applications and watch the system learn your exact writing style. Section-aware learning ensures backgrounds sound like the backgrounds YOU usually draft.
Do anything frontier AI models can do, plus every patent-specific optimization you need. Create custom workflows, use agent mode for autonomous execution, or build your own multi-step processes. The tool adapts to you, not the other way around.
Every detail designed by patent attorneys who use these tools daily in their own practice. You can feel the difference in the subtle details—this isn't software developers guessing what patent work requires.
As AI models improve, you automatically benefit. As model costs decrease, those savings pass directly to you. New features use the same tokens you already have—no upsells, no new "modules" to buy.
Tokens are the universal currency for all LLM Sandbox features—drafting, office action responses, searches, figure generation, everything. While usage varies based on complexity, 100k tokens typically allows you to draft 3-4 complete patent applications, or respond to 4-8 office actions, or some combination of both. The key advantage: as we add new features, they use the same token pool you already have. No upsells, no new "modules" to buy.
No, we never train on user data. We only retain data you explicitly request (like saved conversations and custom prompts), and you can delete these at any time. Everything else—uploaded documents, generated content—is automatically deleted when you sign out. We built our system so no human ever comes into contact with your content. It's fully automated processing with zero human access. Your confidential information stays confidential.
Never. The tool is explicitly designed to augment, not replace, human expertise. You make the strategic decisions—which arguments to pursue, how to amend claims, what scope to target. The AI accelerates execution of your strategy and eliminates repetitive tasks, but your professional judgment drives every meaningful decision.
We run an efficient operation with minimal overhead, and we don't play pricing games. Other platforms constantly upsell new "modules" and lock features behind paywalls. We give you one token pool that works for everything. We actually use MORE expensive models than competitors, but our efficient operations let us pass savings directly to you. It's almost the same cost as subscribing to OpenAI or Anthropic directly.
Yes! Upload 1-4 example applications and watch the tool adapt to your exact drafting preferences. Maintain different styles for different clients, specify word counts and paragraph structure, and ensure every section reflects your voice and strategic choices—not a one-size-fits-all template requiring hours of editing.
Draft 2,000+ words of quality figure descriptions in minutes instead of hours. Systematically analyze office actions and prior art without re-reading documents multiple times. The tool gives you "reading superpowers"—it can search, summarize, and extract information from lengthy documents in seconds, dramatically reducing the repetitive analysis that consumes so much of your time.
Three key differences: (1) Built by patent attorneys who use it daily, not software developers—you can feel this in the subtle details. (2) True flexibility—it's a sandbox you shape however you want, not a rigid workflow someone else designed. (3) Honest pricing—one token pool for everything, no constant upsells, about half the cost of competitors. We respect that you know your practice better than we do.
Absolutely not. The tool drafts individual sections rather than complete specifications, so you review and approve each piece. Don't like the first output? Just tell it what to change in plain language—make it longer, focus on different aspects, adjust the tone. The conversational interface lets you refine iteratively until it's exactly what you want.
Yes! Custom prompts let you encode any repetitive task specific to your practice—checking for problematic language, generating specific types of claim variations, responding to particular rejection types, or anything else you do regularly. You can even share these prompts with your team to standardize best practices across your firm.
Yes, but it's worth it. We prioritize flexibility and control over simplicity, so there's some upfront investment in learning the tool. However, practitioners who take the time to master it produce significantly better work product than they could with simpler, more automated alternatives. Think of it as learning to drive a high-performance vehicle—more effort initially, but far more capability once you know what you're doing.
