US Patent Attorney — Prosecution & Litigation

Mercor

AI Expert - Legal Contractor
United States $110 – $125/hr October 31, 2026

Job description

Client: Pearson

About the Role Mercor is partnering with a leading AI lab to train frontier models on high-quality legal reasoning data. We're hiring US patent attorneys with prosecution and/or litigation experience for a focused evaluation project. You'll review model-generated work product on patent matters, judge its quality, and mark legal, technical, factual and citation errors directly in the materials.

What You'll Do

  • Review patent-related outputs (prosecution and/or litigation work product) and assess their quality against defined dimensions

  • Annotate inline, flagging legal, technical, factual, claim-construction and citation errors

  • Provide clear, well-reasoned explanations for each judgment

  • Complete all assigned reviews within the review window

  • Attend a short onboarding session before kickoff

You're a Good Fit If You

  • Are admitted to practice in at least one US state (active bar membership)

  • Have 3+ years of US patent practice — patent prosecution (drafting/prosecuting applications before the USPTO) and/or patent litigation (infringement, validity, claim construction)

  • For prosecution work: are registered to practice before the USPTO (patent bar, registration number)

  • Hold a technical or scientific degree (engineering, computer science, life sciences, chemistry, physics or similar)

  • Hold a J.D. from an ABA-accredited law school

  • Write clearly and pay close attention to detail

Bonus Qualifications

  • USPTO registration number (patent bar)

  • Experience at an AmLaw 100 firm or a leading patent boutique

  • Federal Circuit or district-court patent clerkship

  • Prior data annotation, AI evaluation or legal-benchmark experience, including prior legal AI projects with Mercor

Role Highlights

  • Time commitment: approximately 12–15 hours total, within a defined review window

  • Immediately required

  • You must complete all required reviews, as the project design depends on every attorney finishing the full set
