Impinj Sues NXP for Patent Infringement
The maker of passive UHF RFID transponder chips and reader chips claims NXP has improperly used its patented innovations in NXP's UCODE integrated circuits.
Jun 06, 2019—
Impinj today filed a patent-infringement lawsuit against rival RFID transponder chip maker NXP Semiconductors. The suit, filed in the Northern District of California, claims that NXP has improperly used 26 of Impinj's patented innovations in its own products.
In an interview with RFID Journal, Jeff Dossett, Impinj's executive VP of sales and marketing, said the infringement includes NXP's UCODE products, and that Impinj has tried unsuccessfully to settle the issue out of court. "We have reached out repeatedly to engage directly with NXP, and they have repeatedly refused to meet with us," he said. "We felt we had no recourse other than to file this lawsuit."
Gahan Richardson, Impinj's senior VP of platform product management and silicon sales, added that Impinj has provided specifics related to Impinj's patent-infringement claims to NXP in an attempt to get them to address the issue out of court. "All of the patents that we put in our complaint today have been communicated to them," he said.
A day after the lawsuit was filed, an NXP spokesperson sent RFID Journal this comment via email: "NXP acknowledges that Impinj filed suit against NXP on June 6 in U.S. District Court. NXP disputes the allegations made by Impinj and intends to vigorously defend its products. As a matter of policy, NXP cannot comment further on any specific aspects of the litigation."
In a blog post on Impinj's website, CEO Chris Diorio wrote: "Our more-than 250 issued and allowed patents are the hard-earned fruits of that passion and our significant investment, dedication and sheer hard work. They also are the foundation of our market leadership. As CEO, I take my responsibility to protect Impinj's inventions seriously. We simply cannot acquiesce to the misappropriation of so much of our intellectual property."
Diorio stressed that Impinj does not wish for the lawsuit to negatively impact the adoption of passive UHF RFID technology. Impinj is not seeking an injunction from the court to stop NXP from selling its UCODE 7 integrated circuits. It is merely asking the court to block NXP from selling its UCODE 8 chips, which were introduced at RFID Journal LIVE! 2017 (NXP to Release More Sensitive UHF Chip With New Functionality).
"We've made every effort to avoid disruption to the supply chains of our partners and our customers," Dossett said. "We've been very thoughtful in how we structured this lawsuit. We are seeking damages for NXP's infringement, and injunctive relief only for UCODE 8 products."
