Fish & Richardson Launches FishStream AI for Patent Work

Fish & Richardson has launched FishStream AI, a proprietary AI tool built in-house to support patent prosecution workflows for its clients.

The launch signals a broader shift in how large IP law firms are deploying AI: not through third-party platforms, but through internally developed tools trained on firm-specific institutional knowledge. For clients managing large patent portfolios, the distinction matters because the tool reflects the firm's own legal standards rather than a generic model.

How It Works

FishStream AI targets three core tasks in patent prosecution: office action analysis, Alice rejection support, and application drafting support.

On office actions, the tool identifies claim limitations at issue, summarizes examiner rejections, flags potential weaknesses, and proposes counterarguments or amendment options for attorney review. For Alice rejections, which involve patent eligibility challenges under a specific U.S. Supreme Court framework, it applies the relevant legal test and generates draft responses. On drafting, it organizes inventor materials, summarizes inventions, suggests follow-up questions, and proposes independent claims.
