Why it matters

Patent prosecution and IP workflow management are emerging as the next major growth area for legal AI, with startups moving from beta to commercial availability and larger legal-tech incumbents entering through partnerships and product expansion. DeepIP launched its AI copilot for patent prosecution out of beta with Microsoft Word integration, while LexisNexis introduced Protégé in PatentSight+ for patent analytics and strategic decision-making. Other vendors including Solve Intelligence and PatSnap are competing in the space, and several patent-focused AI startup CEOs have disclosed ongoing partnership discussions with major legal-tech companies, though specific deal terms remain undisclosed.

The shift reflects accelerating adoption among IP professionals. Industry data shows AI tool adoption in IP practice rose from 57 percent in 2023 to 85 percent in 2025, with AI becoming standard in prior-art searching, patent landscape analysis, claim drafting, office-action responses, and prosecution-history review. The specific terms of pending partnerships between startups and incumbents have not been announced.

For patent practitioners, the consolidation matters because it signals the market is moving from experimentation to competition. Patent work combines specialized workflows with immediate productivity gains—a rare combination in legal AI—making it one of the few segments where AI vendors can demonstrate measurable ROI. Attorneys should monitor which incumbents acquire or partner with which startups, as those moves will likely determine which tools become standard in prosecution workflows. The ongoing legal uncertainty around AI and patentability across jurisdictions is also making patent strategy more complex and more valuable, which is accelerating both demand and investment in these tools.
