Company profile

Hong Kong Lute Technology Co., Limited is a Hong Kong-incorporated company (Hong Kong company code 3069869) with a registered address at Room 02, 21/F, Hip Kwan Commercial Building, 38 Pitt Street, Yau Ma Tei, Kowloon. In the W.D. Wash. pleadings it identifies itself as a subsidiary of Shenzhen Root Technology Co., Ltd. (a/k/a Shenzhen Root Innovation Technology Co., Ltd.), the Shenzhen-based parent of the Momcozy mother-and-baby group. It is separately registered as a foreign entity in Colorado (Aurora, CO). Its CEO/Executive Director of record is Pan Junyu. The parent group was founded in 2017 and is privately held; company recruitment materials cite roughly 2,200 employees and 2024 sales of about RMB 3 billion, though those figures are self-reported and CB Insights lists the business only as private-equity backed (Aokasi Private Equity Investment Fund).

Operations. This is an operating company, not an NPE. As part of the Momcozy group it sells maternity and infant-care consumer products: wearable breast pumps, pumping and nursing bras, maternity pillows, baby monitors, bottle-washing/sterilizing appliances, sound machines and milk-storage containers, distributed through Amazon, Walmart, Target, its own site and other channels in dozens of countries. Hong Kong Lute itself acts as the regulatory-facing entity for the group, appearing in FCC equipment authorizations as the applicant for video baby monitor models (e.g., B10-HD, BM03-A).

Litigation posture. The case data show 1 tracked case as plaintiff and 0 as defendant. This is not a typical NPE pattern: the single suit is a declaratory-judgment action for non-infringement and invalidity filed pre-emptively by the Momcozy entities, and the opposing party counterclaimed for infringement — i.e., an operating brand defending against a competitor's patent assertions. Venue is the Western District of Washington (Seattle), not a plaintiff-friendly NPE district.

Notable case. Shenzhen Root Technology Co., Ltd. et al. v. Chiaro Technology, Ltd. d/b/a Elvie (W.D. Wash., No. 2:23-cv-00631-KKE, filed April 28, 2023). Elvie counterclaimed on four wearable breast-pump patents ('893, '380, '454, '381); Hong Kong Lute is one of several named plaintiffs/counterclaim defendants. The court stayed the case in April 2025 pending Elvie's Chapter 15 recognition proceeding (In re Chiaro Technology Ltd., Bankr. D. Del.). Separately, in September 2026 the USITC instituted Inv. No. 337-TA-1522 on a Willow Innovations / Willow Blossom HoldCo complaint naming Hong Kong Lute (Aurora, CO) and Shenzhen Root Innovation as respondents.

Shenzhen Root Technology Co., Ltd. et al. v. Chiaro Technology, Ltd. d/b/a Elvie

dismissed with prejudice (consent judgment of non-infringement)
Docket:
2:23-cv-00631-KKE
Filed:
2023-04-28
Terminated:
2026-01-05

Momcozy entities filed a DJ action against Chiaro/Elvie regarding the '893 patent. Elvie counterclaimed and later asserted the '893, '380, '381, and '454 patents against Momcozy's V1 and V2 products. The case was stayed due to Chiaro's bankruptcy and resolved by a consent judgment of non-infringement for Momcozy and dismissal with prejudice of Elvie's infringement counterclaims.
