PatentAssist.ai
PatentAssist.ai is a browser-based AI workspace for patent professionals, in-house IP teams, startups and inventors. It turns invention disclosures into claim sets first, then drafts complete or provisional patent specifications, abstracts and figure descriptions in USPTO, EPO, DPMA and IP India formats. Users can review and edit drafts with an AI copilot and export to DOCX. The platform searches more than 20 million US, European and Indian patent records using natural-language and field queries, and prepares patentability search reports. Its drawing tool builds figures and reference numerals from claims and generates patent illustrations. Patent search is available without an account; drafting plans include a seven-day trial. The interface supports English, German, Spanish and French. Customer invention content is not used to train models, and AI processing runs through Azure OpenAI in EU regions.

ClaimHit
ClaimHit is an AI-powered agentic platform for patent infringement intelligence, designed for patent owners, IP attorneys, and corporate IP teams to perform initial infringement screenings in about 60 seconds. Its key innovation is the multi-model consensus engine. Instead of depending on a single AI model, ClaimHit runs nine advanced AI models concurrently - Claude Sonnet, Haiku (Anthropic), GPT-4o, GPT-4o Mini (OpenAI), Gemini 2.5 Flash Lite (Google), DeepSeek, Mistral, and Perplexity Sonar - each working independently without knowing the others' outputs. The results are then combined using a unique four-factor scoring system.
The platform is versatile across all domains, supports team collaboration, offers a purely consumption-based pricing model, and provides MCP server integration. You can order either AI Charts, which takes about 90 seconds to generate, or request manually vetted charts right from the platform.
