Case Overview
The Parties
⚖️ Plaintiff
A patent assertion entity (PAE) holding IP rights in network communications technology. Entities of this structure typically monetize patents through licensing and litigation rather than direct product commercialization.
🛡️ Defendant
A multinational IT services, consulting, and business solutions corporation headquartered in Mumbai, India. TCS delivers managed network services, IT infrastructure, and digital transformation solutions to enterprise clients.
Patent at Issue
This landmark case involved U.S. Patent No. 9,584,633 B2 covering methods and systems for managing network communications. Utility patents are registered with the U.S. Patent and Trademark Office (USPTO) and protect functional inventions rather than ornamental appearance.

The Verdict & Legal Analysis
Outcome
On **March 5, 2026**, Judge Gilstrap accepted the parties’ Joint Motion and Stipulation of Dismissal With Prejudice pursuant to Rule 41 of the Federal Rules of Civil Procedure. All of Calibrate Networks’ claims against TCS were dismissed with prejudice. Each party bore its own attorneys’ fees and costs. No damages were awarded, no injunctive relief was granted, and no consent judgment was entered on the public record.
Specific settlement terms, if any private agreement exists between the parties, were not disclosed in court filings.
Key Legal Issues
Because dismissal occurred before any substantive merits ruling—no claim construction order, no invalidity determination, no infringement finding—the court made no public legal findings on claim construction, validity of the asserted claims, infringement under various theories, or damages methodology.
The dismissal **with prejudice** is legally significant: Calibrate Networks is permanently barred from re-asserting the same claims of U.S. Patent No. 9,584,633 B2 against TCS based on the same accused products and conduct. This is a meaningful outcome for TCS, providing definitive closure against this particular assertion without the cost or risk of full litigation.
