Case Overview
The Parties
⚖️ Plaintiff
Seattle-based semiconductor company, a pioneer in RAIN RFID technology, with its Monza line of endpoint ICs deployed globally.
🛡️ Defendant
Global semiconductor leader with headquarters in the Netherlands, whose UCODE family of RFID ICs directly competes with Impinj’s Monza chips.
The Patents at Issue
Impinj asserted nine U.S. patents spanning RFID endpoint IC architecture and functionality, demonstrating a portfolio assertion strategy designed to maximize litigation leverage.
- • US10776198B1 — Advanced RFID IC features
- • US7215251B2 — Earlier-generation RFID tag IC innovations
- • US7116240B2 — Earlier-generation RFID tag IC innovations
- • US7472835B2 — Earlier-generation RFID tag IC innovations
- • US10929734B1 — Advanced RFID IC features
- • US8665074B1 — Signal processing and IC design
- • US7733227B1 — Mid-portfolio RFID circuit and communication claims
- • US7246751B2 — Mid-portfolio RFID circuit and communication claims
- • US7388468B2 — Mid-portfolio RFID circuit and communication claims

The Verdict & Legal Analysis
Outcome
The case terminated via **stipulated dismissal with prejudice** on March 13, 2024, pursuant to **Federal Rule of Civil Procedure 41(a)(1)(A)(ii)**. Both parties agreed to dismiss all claims, counterclaims, and affirmative defenses, with each party bearing its own costs and attorneys’ fees. No damages award, injunction, or public findings on infringement or validity were issued, indicating a confidential settlement.
Key Legal Issues
This high-stakes dispute centered on nine U.S. patents covering RFID endpoint integrated circuit technology. The mutual dismissal, with each side bearing its own fees, suggests the settlement was negotiated from a position of relative parity. NXP’s potential counterclaims (though not detailed publicly) likely introduced invalidity challenges or countervailing patent assertions that balanced litigation risk for Impinj. This case reinforces the effectiveness of broad patent portfolio assertions in semiconductor disputes and highlights the common outcome of settlement prior to trial in complex IP cases in the Western District of Texas.

Impinj asserted nine U.S. patents: US10776198B1, US7215251B2, US7116240B2, US7472835B2, US10929734B1, US8665074B1, US7733227B1, US7246751B2, and US7388468B2 — covering RFID endpoint IC technology across multiple generations.
The case was dismissed with prejudice on March 13, 2024, pursuant to a mutual settlement agreement, with each party bearing its own costs and attorneys’ fees. No damages award or infringement finding was publicly issued.
It reinforces the value of broad portfolio assertions in semiconductor disputes and highlights that well-matched adversaries with counterclaims frequently resolve cases through negotiated settlement rather than trial adjudication.
Companies developing RFID solutions can protect themselves by conducting comprehensive freedom-to-operate (FTO) analysis, thoroughly documenting the evolution of their IC designs, pursuing design-around strategies for high-risk patent claims, and strategically filing their own patents early. PatSnap Eureka’s FTO tools help R&D and IP teams identify potentially blocking RFID patents before products go to market.
