Case No. 20-cv-4806 

Judge Steven C. Seeger 

Magistrate Judge Jeffrey Cole 

FILED UNDER SEAL 

SECOND AMENDED COMPLAINT

 Plaintiff Hangzhou Chic Intelligent Technology Co., Ltd. (“Chic”) and Unicorn Global, 

Inc., (“Unicorn”) bring this action against the Defendants identified in attached Schedule A 

(collectively, “Defendants”) and allege as follows: 

NATURE OF ACTION

1. This action is for patent infringement arising under the patent law of the United 

States, 35 U.S.C. § 1 et seq., including 35 U.S.C. §§ 271, 281, 283, 284, 285, and 289. 

2. Plaintiffs have filed this action to combat e-commerce store operators who trade 

upon Plaintiffs’ reputation and goodwill by making, using, offering for sale, selling and/or 

importing into the United States for subsequent sale and use of unauthorized and unlicensed 

products, namely the hoverboards shown in Exhibit 1, that infringe Plaintiffs’ patented designs 

(“Infringing Products”). Defendants create e-commerce stores operating under one or more seller 

aliases identified in Schedule A (collectively, “Defendant Internet Stores”) that are making, using, 

offering for sale, selling, and/or importing into the United States for subsequent sale or use of 

Case: 1:20-cv-04806 Document #: 37 Filed: 09/10/20 Page 1 of 19 PageID #:1784
 2 

Infringing Products to unknowing consumers. Defendant Internet Stores share unique identifiers 

establishing a logical relationship between them and Defendants’ operations, which arises out of 

the same transaction, occurrence, or series of transactions or occurrences. Defendants attempt to 

avoid and mitigate liability by operating one or more Defendant Internet Stores to conceal both 

their identities and the full scope and interworking of their operation. 

3. Plaintiffs are forced to file this action to combat Defendants’ infringement of its 

patented designs, as well as to protect unknowing consumers from purchasing Infringing Products 

over the Internet. Plaintiffs have been and continue to be irreparably damaged from the loss of its 

lawful patent rights to exclude others from making, using, selling, offering for sale, and importing 

its patented designs as a result of Defendants’ actions and seeks injunctive and monetary relief. 

JURISDICTION AND VENUE 

4. This Court has original subject matter jurisdiction over the claims in this action 

under the Patent Act, 35 U.S.C. § 1, et seq., 28 U.S.C. §§ 1331 and 1338(a)-(b). 

5. Venue is proper in this Court under 28 U.S.C. § 1391, and this Court may properly 

exercise personal jurisdiction over Defendants because each of the Defendants directly targets 

business activities toward consumers in the United States, including Illinois, through at least the 

fully interactive, e-commerce stores, operating under the Defendant Internet Stores. See Schedule 

A. Specifically, Defendants have targeted sales to Illinois residents by setting up and operating ecommerce stores that target United States consumers using one of more Defendant Internet Stores, 

offer shipping to the United States, including Illinois, accept payment in U.S. dollars and, on 

information and belief, have sold products featuring Plaintiffs’ patented designs to residents of 

Illinois. Each of the Defendants is committing tortious acts in Illinois, is engaging in interstate 

commerce, and has wrongfully caused Plaintiff substantial injury in Illinois.

THE PARTIES 

6. Plaintiff Chic is a high-tech company that manufactures and licenses hoverboard 

products for sale in the United States. Chic is supported by Zhejiang University Ministry of 

Education Computer Aided Product Innovation Design Engineering Center, the Zhejiang 

University International Design, and Zhejiang Key Laboratory of Service Robot. Chic is located 

in the Liangzhu University Science and Technology Park, Yuhang District, Hangzhou, China 

7. Chic designs, manufactures, and sells hoverboards, among other technologies, 

which incorporate Plaintiffs’ patented design (collectively, “Plaintiffs’ Products”). Chic has been 

assigned approximately 400 granted patents related to technologies associated with the products 

at issue here, four of which are the subject of this action and listed in Exhibit 2 (“Patents-in-Suit” 

or “Plaintiffs’ Designs”). Plaintiffs’ Designs are used to produce Plaintiffs’ Products. 

8. Plaintiff Unicorn is a corporation organized and existing under the laws of the State 

of California, having its principle place of business in the City of Industry, California. Unicorn is 

the exclusive U.S. distributor of Plaintiffs’ Products. Unicorn, through its affiliates and licenses, 

operates websites which promote and sell genuine Plaintiffs’ Products, and which feature 

proprietary content, images and designs exclusive to Plaintiffs. 

9. Defendants are individuals and business entities of unknown makeup who own 

and/or operate one or more Defendant Internet Stores identified in Schedule A and/or other seller 

aliases not yet known to Plaintiffs. Upon information and belief, Defendants reside and/or operate 

in the People’s Republic of China or other foreign jurisdictions with less efficient intellectual 

property enforcement systems, or redistribute products from the same or similar sources in those 

locations. Defendants have the capacity to be sued under Federal Rule of Civil Procedure 17(b). 

Case: 1:20-cv-04806 Document #: 37 Filed: 09/10/20 Page 3 of 19 PageID #:1786
 4 

10. On information and belief, Defendants either individually or jointly, operate one or 

more Defendant Internet Stores listed in Schedule A. Tactics used by Defendants to conceal their 

identities and the full scope of their operation make it virtually impossible for Plaintiffs to learn 

Defendants’ true identities and the exact interworking of their network. If Defendants provide 

additional credible information regarding their identifies, Plaintiffs will take appropriate steps to 

amend the Complaint. 

FACTUAL ALLEGATIONS 

11. Chic has been issued with several U.S. design patents relating to hoverboard 

products, including but not limited to, the Patents-in-Suit, U.S. Design Patent Nos. D737,723 (“the 

’D723 patent”), D738,256 (“the ’D256 patent”), D785,112 (“the ’D112 patent”), and D784,195

Claim Issue Date 

19. Jiawei Ying is the named inventor of the Patents-in-Suit, and he has assigned all 

rights, title, and interest to the patents to Chic. 

20. Chic has licensed enforcement rights for the Patents-in-Suit to Unicorn. 

21. Plaintiffs utilize the Patents-in-Suit when designing, manufacturing, and selling 

Plaintiffs’ Products. The Patents-in-Suit have revolutionized ornamental design for hoverboards 

that have a central support platform. 

Case: 1:20-cv-04806 Document #: 37 Filed: 09/10/20 Page 11 of 19 PageID #:1794
 12 

22. The Patents-in-Suit have streamline shapes that are appealing to United States 

customers. Specifically, the ’D723 patent and the ’D256 patent have defined the fundamental 

ornamental configurations of the hoverboard product class. The ’D112 patent features a soft edge 

between the central support platform and the fenders, and the ’D195 patent features a sharper edge. 

23. The Patents-in-Suit are stylish and modern, and are visually pleasing to the 

consumers in the United States. Plaintiffs’ Designs have become enormously popular to 

consumers of all ages, resulting in the sale of thousands of units in the United States. 

24. Plaintiffs have identified numerous e-commerce stores, including Defendant 

Internet Stores, that offer for sale and/or selling Infringing Products to consumers in this Judicial 

District and throughout the United States. E-commerce sales, including through stores like those 

of Defendants, have resulted in a sharp increase in the shipment of unauthorized products into the 

United States. See Excerpts from Fiscal Year 2018 U.S. Customs and Border Protection (“CBP”) 

Intellectual Property Seizure Statistics Report at Exhibit 3. 

25. Third party service providers like those used by Defendants do not adequately 

subject new sellers to verification and confirmation of their identities, allowing infringers to use 

untraceably identifiers, such as false names and addresses, when registering with e-commerce 

platforms. See “Combating Trafficking in Counterfeit and Pirated Goods,” prepared by the U.S. 

Dep’t of Homeland Security’s Office of Strategy, Policy, and Plans (Jan. 24, 2020) at Exhibit 4. 

26. Defendants have targeted sales to Illinois residents by setting up and operating ecommerce stores that target United States consumers using one or more Defendant Internet Stores. 

27. Upon information and belief, Defendants have sold and are selling Infringing 

Products on their e-commerce website, offered and are offering shipping to the United States, 

including Illinois, and have accepted and are accepting payment in U.S. dollars. 

Case: 1:20-cv-04806 Document #: 37 Filed: 09/10/20 Page 12 of 19 PageID #:1795
 13 

28. Defendants concurrently employ and benefit from substantially similar advertising 

and marketing strategies. For example, Defendants facilitate sales by designing the e-commerce 

stores operating the Defendant Internet Stores so that they appear to unknowing consumers to be 

authorized online retailers, outlet stores, or wholesalers. Defendant Internet Stores often include 

content and images that make it difficult for consumers to distinguish such stores from an 

authorized retailer. In addition, Defendant Internet Stores appear sophisticated and accept 

payment in U.S. dollars via credit cards, Paypal, and/or Amazon Pay, for example. 

29. Plaintiffs have not licensed the Patents-in-Suit to the Defendants and none of the 

Defendants are authorized retailers of genuine Plaintiffs’ Products. 

30. On information and belief, Defendants have engaged in fraudulent conduct when 

registering the Defendant Internet Stores by providing false, misleading and/or incomplete 

information to e-commerce platforms. 

31. On information and belief, Defendants have anonymously registered and 

maintained seller aliases to prevent one from learning their true identities and the scope of their ecommerce operation. 

32. On information and belief, Defendants regularly register or acquire new seller 

aliases for the purpose of offering for sale and selling Infringing products. Such registration 

patterns are one of the many tactics used by Defendants to conceal their identities and the 

interworking of their operations, as well as to avoid being shut down. 

33. Despite operating under multiple fictitious aliases, the Defendant Internet Stores 

often share unique identifiers, such as templates with common design elements with no contact 

information or other identifying information, keywords, advertising tactics, similarities in prices 

and quantities, same incorrect grammar and misspellings, and/or use of the same text and imagines. 

Case: 1:20-cv-04806 Document #: 37 Filed: 09/10/20 Page 13 of 19 PageID #:1796
 14 

34. Infringing Products sold by the Defendant Internet Stores bear similar irregularities 

and indicia of being unauthorized to one another, suggesting that Defendants are interrelated and 

that the Infringing Products come from and were manufactured by a common source. 

35. On information and belief, Defendants maintain off-shore accounts and regularly 

move funds from their financial accounts to off-shore bank accounts outside this Court’s 

jurisdiction to avoid payment of any monetary judgment awarded to Plaintiffs. 

36. On information and belief, Defendants are an interrelated group of infringers 

working in active concert to knowingly and willfully make, use, offer for sale, sell, and/or import 

into the United States for subsequent sale or use Infringing Products in the same transaction, 

occurrence, or series of transactions or occurrences. 

37. Defendants, without any authorization or license from Plaintiffs, have jointly and 

severally, knowingly and willfully made, used, offered for sale, sold, and/or imported into the 

United States for subsequent resale or use products that directly and/or indirectly infringe 

Plaintiffs’ Designs, irreparably harming Plaintiffs.
