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.

Attorney Oversight Built In

The tool operates on what Fish describes as a "non-negotiable human-in-the-loop" model. Every output serves as a starting point, not a final work product. Attorneys retain control over legal strategy, claim development, and all client-facing materials.

Tracy Hitt, the Fish principal who developed FishStream AI, said the tool "provides a logical starting point built on our institutional knowledge and followed by a non-negotiable human-in-the-loop approach that integrates attorney experience and judgment, with a focus on delivering excellent value to clients."

In complex matters, the platform cross-references claim elements against cited prior art references, surfaces key distinctions, and generates claim charts to support attorney review.

Security and Deployment

FishStream AI runs entirely within Fish's secure enterprise environment. The firm has built strict safeguards around client data, with no reliance on external platforms or third-party AI services for processing sensitive information.

Hitt noted: "Staying at the leading edge of technology is critical to how we serve clients, but innovation only matters if it's applied responsibly. With FishStream AI, we're pairing advanced AI capabilities with careful oversight and attorney judgment to drive stronger results and greater value for our clients."

The firm has not disclosed the underlying AI models powering the tool, the volume of patent matters processed through it, or pricing implications for clients.
