Patent Watch

PatentWatch is aimed squarely at a workflow most general-purpose AI tools handle badly. When an LLM is asked to compare a claim limitation to a datasheet, the failure mode isn't a refusal — it's a confident, fabricated mapping. PatentWatch structures the problem differently: it breaks the claim into elements, retrieves specification context alongside each element, surfaces the specific evidence excerpt, and labels a status (the demo shows "Meets" for a rectifier limitation backed by a passage reading "an integrated, self-driven synchronous rectifier that enables high-efficiency AC to DC power conversion," and "Partially meets" for a controller limitation where the cited switches support load modulation but the passage doesn't establish how the controller computes the voltage difference). That granularity — and the willingness to return a partial rather than a binary — is what makes the output reviewable rather than aspirational.The standards side is the real differentiator. Mapping patents to telecom, Wi-Fi, Bluetooth, and video/audio coding standards with cited evidence per mapping is work that normally consumes weeks of a SEP team's calendar, and it's a niche few competitors staff for. Prior-art and validity screening across both patents and non-patent literature, compared element-by-element, addresses the other half of the IP lifecycle.Strengths: element-level parsing, cited evidence per conclusion, visible reasoning, SEP/codec mapping, and support for your own supplied source material rather than only public corpora. The honesty about partial matches is a genuine strength — a tool that only says "yes" would be useless to a litigator.Weaknesses: the accuracy ceiling is set by the quality of publicly available product documentation, which varies wildly by accused product. The evidence is silent on a public API, so teams wanting to pipe results into internal tooling should raise that during evaluation rather than assume it.Where it fits: firms with recurring litigation or licensing work, corporate IP groups triaging large portfolios, and standards teams who currently build essentiality maps by hand in spreadsheets. Where it doesn't: solo inventors with one patent, people who want a fast general answer rather than a defensible chart, and anyone who needs a self-serve trial before they can get budget approved.Sizing relative to alternatives: against general assistants like ChatGPT or Claude, PatentWatch trades breadth for domain grounding and citations. Against traditional patent search databases, it trades exhaustive Boolean search syntax for element-level AI analysis with visible reasoning and status labels. The two aren't mutually exclusive, and the practical pattern we'd expect is PatentWatch for chart drafting and screening with your existing search platform for the final exhaustive sweep.
