Solutions

One model.
Four workflows.

Nulity is built around the moments an IP team actually needs prior art — IPR petitions, patent-owner response drafting, acquisition due diligence, and invalidity contentions in district-court litigation. The same outcome-aligned model powers all four.

001

IPR petitions

IPR petitioner · IP litigation boutique

Build invalidity grounds for an inter partes review filing. The model surfaces the prior-art universe most likely to land §102 anticipation and §103 obviousness arguments before the PTAB.

  • Outcome-aligned ranker trained on Final Written Decisions — the model learns which references actually win, not just which match.
  • Side-by-side compare for §103 obviousness combinations.
  • Save shortlisted references into a matter with status + notes; export to a Word draft as a starting point for the petition.
002

Patent-owner response

Defense counsel · patent owner

Counter a petitioner's invalidity grounds. Find the prior art they should have cited but didn't — and the distinguishing references that strengthen claim-construction arguments.

  • Forward-citation lookup flags obscure refs that lack credibility weight.
  • Inline reader with highlights to mark distinguishing language for the response brief.
  • Bulk mode runs all the asserted-claim families at once when the petition spans a portfolio.
003

Acquisition due diligence

Patent acquisition team · corporate IP

Before buying a patent or portfolio, find the references most likely to surface in a future invalidity challenge. Surface the risk before the deal closes.

  • Bulk search across an entire portfolio in one pass; per-patent risk summary.
  • Structural evidence chips (shared CPC + shared citations) flag claim families with deep prior-art neighborhoods.
  • Matters workspace groups every asset under one case for legal-team handoff.
004

Litigation invalidity contentions

Trial counsel · district-court litigation

Stand up invalidity contentions on the local-patent-rules clock. Replace weeks of manual prior-art search with a ranked, explained shortlist on day one.

  • Snippet-level attribution shows which passages of each reference earned the rank — drops directly into element-by-element charting.
  • Save references per asserted patent inside one matter; track Keep / Shortlist / Dismissed.
  • Word-doc export gives the team a structured starting point before manual claim-element alignment.

Same primitives, every workflow

Outcome-aligned ranker

Fine-tuned on the only ground truth that matters: PTAB final decisions on whether a reference invalidates.

Matters workspace

Named cases that group every search, saved reference, and note. Triage status carries across sessions.

Inline reader + highlights

Read the full patent inside Nulity. Highlight passages that prove anticipation; they persist into the matter.

Side-by-side compare

Diff two references on claims, description, shared CPC codes, and shared citations. The §103 foundation.

Forward citations

See which other patents in the corpus cite each reference — the credibility signal that distinguishes load-bearing prior art from obscure misses.

Word-doc export

One click turns a ranked result list into a .docx that drops into invalidity contentions or petition drafts.
