US Patent Attorney — Prosecution & Litigation

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
