I'll research this company before writing the profile.
Shenzhen Root Technology Co., Ltd. (Chinese: 深圳路特科技有限公司) is a privately held Chinese consumer-products company headquartered in Shenzhen, Guangdong. It was founded in 2017 and has also done business as Shenzhen Lutejiacheng Network Technology Co., Ltd.; it changed its name to Shenzhen Lute Innovation Technology Co., Ltd. in September 2023. It is the parent of Hong Kong Lute Technology Co., Limited and Shenzhen Conglin E-Commerce Co., Ltd., and is affiliated with Shenzhen Jinruihang Technology, Shenzhen Xitao Network Technology, and ROOT Technology Ltd. CB Insights lists Momcozy as formerly known as Shenzhen Root Innovation Technology Co., Ltd. Chinese campus-recruiting materials report roughly 500 employees and revenue above RMB 1.6 billion (2023) and RMB 3 billion (2024) — figures that are company-sourced and not independently audited here. No public ticker was identified.
Products / operations. The group operates the maternal-and-infant technology brand Momcozy, selling wearable breast pumps (S9, S9 Pro, S12, S12 Pro, M1, M5, V1, V2), nursing bras, maternity pillows, milk storage and cleaning products, baby monitors, and postpartum-recovery items. Distribution runs through momcozy.com and marketplaces including Amazon, plus U.S. retail (Walmart, Target). A related group entity, Shenzhen Root Innovation Technology Co., Ltd., holds FDA 510(k) clearances for obstetric/gynecologic devices. This is an operating company, not an NPE.
Litigation posture. Both tracked cases show Shenzhen Root as plaintiff and none as defendant, but the record reflects an active two-way dispute over wearable-breast-pump patents rather than assertion of an acquired portfolio. In Shenzhen Root Technology Co., Ltd. et al. v. Chiaro Technology, Ltd. d/b/a Elvie (2:23-cv-00631-KKE, W.D. Wash., filed April 2023), Shenzhen Root sought declaratory judgment of non-infringement of Elvie's '893 patent; Elvie counterclaimed infringement of the '893, '380, '454, and '381 patents. Venue is the Western District of Washington (Seattle), not a plaintiff-friendly Texas district.
Notable cases. The district court case was stayed in April 2025 pending Chiaro Technology's Delaware bankruptcy (In re Chiaro Technology Limited, No. 25-10691). Willow Blossom Holdco Limited and Willow Innovations, Inc. subsequently acquired the patents, and Shenzhen Root filed IPRs challenging the '454 and '381 patents; institution was granted in IPR2025-00554 on October 14, 2025, with a Sotera stipulation limiting overlapping grounds in the district court.

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.
