On June 10 and 11 local time in the United States, DJI filed a lawsuit in the U.S. District Court for the Eastern District of Texas, accusing Innova and its affiliated companies of patent infringement. This lawsuit directly targets Innova’s Luna series handheld gimbal cameras, which debuted in the US on June 9. DJI accuses these products of infringing on two design patents and four invention patents they hold, involving core underlying technologies such as pan-tilt electromechanical control and shooting control. Faced with the lawsuit, Yingshi Innovation quickly fought back. On June 12, Innova filed a patent counterclaim against DJI in the United States, involving five invention patents covering key technologies such as gimbal stabilization algorithms, gimbal orientation control, camera smoothing and stabilization, motion data overlay, and panoramic video stabilization. At the same time, Yingshi Innovation simultaneously filed a request to invalidate related related family patents with the China National Intellectual Property Administration. This marks the first patent litigation battle between the two companies in overseas markets, following DJI’s domestic drone patent infringement lawsuit against Innova in March 2026.

I. Complete Timeline of the Litigation Event

01 May 26: DJI sent a patent notification letter in advance

DJI disclosed that as early as two weeks before Yingshi Luna’s overseas listing, it had sent a patent risk notification letter to Yingshi Innovation, listing the protection scope of six U.S. patents involved and warning that its new products clearly posed infringement risks. DJI believes that Insilicon, fully aware of the patent boundaries, still pushed ahead with mass production and global launch sales, constituting “intentional infringement” and that it has the right to claim triple punitive damages under U.S. patent law.

02 June 9: YingStone Luna series debuts in the United States

Yingshi officially launched the Luna Ultra dual-camera gimbal camera targeting the Osmo Pocket. With its lightweight body, fliptable large screen, and panoramic stabilization, it targets the Vlog creator and outdoor photography market, simultaneously opening pre-sales through both online and offline channels, positioning the US as the core overseas incremental market for the new product. Prior to this, DJI’s Osmo Pocket series had dominated the global gimbal segment for many years, marking a shift from mismatched competition to direct confrontation.

03 June 10-11: DJI submitted two independent infringement complaints

DJI and its Osmo brand are suing Insilicon Innovations and its four domestic and overseas affiliated companies in two separate cases, with case numbers 2:26-cv-00462 and 2:26-cv-00463, both handled by the U.S. Court for the Eastern District of Texas, which has extensive patent case experience. The two cases focus respectively on infringement of design patents and invention patents. Filing them separately strengthens the protection mechanism and avoids prolonged single case trials that delay injunction applications.

04 June 12: Shadowstone launches a dual counterattack

Facing legal pressure from DJI, Innova simultaneously launched two countermeasures: First, filed a patent countersuit in the same U.S. court, accusing DJI Osmo Pocket and multiple pan-tilt stabilization invention patents for multiple products on sale; Second, simultaneously filing a request to invalidate DJI’s related patent family to the China National Intellectual Property Administration, weakening DJI’s foundation for rights protection from the root cause of patent confirmation. Thus, both sides formed a dual-front battlefield of “mutual lawsuits by the U.S. and confrontation within the country.”

2. Offense and Defense: DJI accusations vs. Shadowstone’s counterattack

2.1 DJI Allegations: Two complaints, six patents

DJI used harsh wording in the complaint, claiming that the Innova Luna series cameras “blatantly and completely copied DJI’s technology and design,” and pointed out that “from appearance design to functional settings, the alleged infringing products are identical to DJI’s nearly ten years of research and patent applications for innovative handheld gimbal camera systems.”

First complaint (2:26-cv-00462): Focus on design patents

DJI accuses the Innova Luna series of “very similar” in appearance to the DJI Osmo Pocket 3—using the same proportions, the same controller with a gimbal architecture, and the same component arrangement.

Second complaint (2:26-cv-00463): Focus on invention patents

DJI accuses the Shadowstone Luna series of infringing on four of its underlying gimbal control invention patents, which cover:

A gimbal control device that can switch between follow mode and lock mode with a single control unit

Integrated subject tracking and real-time display functions, handheld gimbal without the need to connect to a separate mobile app

A gimbal control method where the target image captured by the device itself drives gimbal motor commands

A system that can operate independently to track subjects and display images on a gimbal screen

DJI believes that Innova promotes features such as the rotating screen appearance, gimbal mode switching, subject tracking technology, and camera shooting direction that follows the user’s controller movements as product differentiation advantages—but these are all innovations developed and patented over many years around the Osmo Pocket series. DJI stated in the complaint: “At the time Yingshi submitted and served this complaint, it was already aware of all the patents involved in the lawsuit and was aware that the alleged product allegedly infringed these patents.” The defendant, knowing the existence of the disputed patent, continued to import, manufacture, use, sell, and promise to sell the accused product, and induced or induced or induced users of the accused products to infringe the disputed patent through related conduct. This constitutes intentional infringement and should be subject to aggravated damages. ”

2.2 Shadowstone Counterattack: Counterclaim + Invalidation Declares dual lines in parallel

(1) U.S. counterclaim

Yingshi submitted counterclaims in the same court, claiming that several DJI gimbal and panoramic camera products on sale infringe on five of its self-developed patents, covering technologies such as multi-level pan-tilt smoothing and stabilization, panoramic video image fusion, pan-tilt dynamic control, and motion shooting data overlay.

The core function of counterclaims is to create litigation checks: even if DJI’s infringement claims are established, Yingshi’s counterclaim patents can be used as bargaining chips to reduce compensation and delay the implementation of the injunction. In global patent cross-licensing negotiations, two-way mutual litigation is the core means for companies to obtain equal negotiation status.

(2) Invalidation declaration of domestic family patents

Yingshi simultaneously filed a request with the National Intellectual Property Administration to invalidate the Chinese patent related to DJI’s patent in question. Although Chinese and U.S. patents are independent, they share the same core technology priority documents. If the National Intellectual Property Administration declares DJI’s domestic patent family patents invalid, it can be directly used in U.S. trials to defend the patent lacking novelty and inventiveness, fundamentally weakening DJI’s rights protection foundation.

3. Why did the two companies go all-in?

Before 2025, DJI and Yingshi will each hold their own territory—DJI dominates consumer-grade drones, while Yingshi reigns supreme with panoramic cameras. But in the summer of 2025, both sides simultaneously targeted each other’s territory: on July 28, Shadowstone officially announced plans to launch panoramic drones, and just three days later, DJI responded by releasing the Osmo 360. Now that Yingshi has launched the Luna series to enter the handheld gimbal camera market for the first time, DJI has immediately fought patent lawsuits, with both sides “fighting” in each other’s core territories. By 2025, DJI will rank first in the global handheld smart camera market with 62.4% of shipments, followed by Innova at 20.4%, together accounting for over 80% of the global market share. IDC data shows that by 2025, global shipments of handheld smart cameras will reach 16.65 million units, an 83% year-on-year increase, and the market size is expected to exceed 40 million units by 2030. The capital market has already reacted—as of June 15, Innova Innovation (688775. SH) is priced at 156.42 yuan per share, down more than 30% so far this year. DJI requested the court to issue a permanent injunction in the lawsuit. Once approved, the Yingshi Luna series would no longer be sold in the United States, directly impacting its overseas expansion pace.

4. Conclusion

This patent lawsuit is no longer just a commercial competition between two companies; it also reflects a major change in the domestic imaging industry: the industry has moved away from the rough phase of simply competing on production capacity and sales, and has officially entered an era of high-quality competition based on core technology competition. DJI relies on self-developed patents to build a solid technical barrier and maintain its overseas market advantage; Yingshi entered the market with a brand-new product and actively countered with counterclaims; both sides are essentially vying for core technology control and global market share. Intellectual property itself is a protective barrier for innovation. If infringement is confirmed, directly copying others’ technology would severely dampen the industry’s R&D enthusiasm and destroy the entire innovation environment; Conversely, if Yingshi is a compliant independent R&D, the market should also embrace healthy competition across different technical routes and promote overall industry progress.
