For many, the perception of “patent trolls” (NPEs) remains rooted in the U.S. Eastern District of Texas—a hub for targeting Chinese tech firms going global, leveraging local courts’ patent-friendly environment to demand exorbitant settlements.

Yet few notice that these patent-driven professional players have long extended their reach into China.

Recently, Insta360’s domestic patent litigation against an NPE entity is set to formally open. This domestic imaging leader, which has dominated global markets with its panoramic cameras, spent two years battling GoPro in an ITC 337 investigation before now facing relentless harassment from overseas NPEs.

After securing a final ITC ruling to stabilize its U.S. market position, a new legal battle has emerged on home turf.

This trial involves far more than just compensation.

From Texas to China: NPEs’ Hunting Tactics Are Never Isolated

To grasp the weight of this domestic case, one must first untangle Insta360’s IP entanglements over the past two years—a natural extension of overseas hunting chains into China.

Insta360’s rise abroad is nearly a history of reactive IP battles. The earliest and most perilous hurdle came from rival GoPro’s ITC 337 investigation, a two-year tug-of-war over a potential U.S. market ban. By February 2026, the ITC’s final ruling largely eliminated the existential risk of being expelled from the U.S. market.

However, lifting the sales ban alert did not end the troubles. Parallel civil lawsuits between the two sides remain unresolved, with ongoing compensation disputes and potential appeals continuing to drain Insta360’s legal and R&D resources.

Industry patent disputes soon followed, with a leading brand suing Insta360 over six drone-related patents and six gimbal control/design patents, with a trial date also approaching.

But these were genuine patent disputes, openly awaiting court rulings. Unexpectedly, true professional hunters—NPEs—were quietly laying traps to ensnare Insta360.

Online reports reveal that U.S. NPE L4T Innovations LLC recently sued Insta360 in the Eastern District of Texas Marshall Federal Court, alleging infringement spanning GPS remote controls for X-series and Ace-series action panoramic cameras, all panoramic and action camera models, and even matching (matching) mobile and desktop editing software—effectively packaging Insta360’s entire product lineup into the lawsuit.

The plaintiff’s demands are unambiguous: a ruling of literal infringement, full compensation for losses, recognition of willful infringement, and triple punitive damages.

This is hardly Insta360’s first NPE ambush.

Prior to this, multiple NPEs—including Contour IP, Monument Peak Ventures, and Sovereign Peak Ventures—have taken turns launching lawsuits, following a typical assembly-line harassment model: as soon as one case concludes, another takes over, always finding new patent angles to spark disputes. Even if they ultimately lose, the prolonged litigation slows down the target company.

Previously, these risks were confined to overseas markets, with the domestic front relatively secure. But with this NPE lawsuit opening in China, that safety buffer has shattered. NPEs, armed with corresponding domestic patent families, are replicating their proven overseas litigation strategies locally, forcing Insta360 into a dual-front war: defending against sales bans and hefty damages abroad while safeguarding market reputation and product bans at home. Neither front allows for complacency.

Why Insta360 Became an NPE Prime Target

NPEs don’t cast their nets randomly; they systematically harvest targets along industry technology chains. Insta360’s selection aligns perfectly with their criteria.

First, the target is “ideal.”

As a leading domestic panoramic camera brand expanding globally, Insta360’s massive sales volume and hardware-to-software ecosystem make it a one-stop target: a single lawsuit can cover its entire product line, maximizing Claim (claim) bases and settlement expectations. For NPEs, suing one vertical leader yields far higher returns than targeting ten SMEs—the best ROI choice.

Second, the patents are highly universal.

Take L4T’s involved patent US11189321 (granted in 2021, with priority dating to 2017) as an example. It protects a system/method for “independent wireless remote control with real-time video recording event marking and highlight capture retrospection.” Technically, it involves external GNSS-equipped remotes tagging moments in real-time, with backend software indexing highlights via timestamps. This “remote tagging + time sync + software review” functionality is now standard across action and panoramic cameras, adopted by nearly all mainstream brands.

NPEs favor such highly universal, industry-wide patents. A single patent can sue multiple companies sequentially, amplifying its monetization leverage—one acquisition cost, multiple settlement payouts.

This “one patent, entire industry” approach is the core of NPE business models.

Third, litigation venue advantages.

In the U.S., they favor Texas’s Eastern District Marshall division—a notorious NPE stronghold known for short trial cycles, juries biased toward patent holders, and average damages far exceeding other regions, maximizing pressure on defendants. In China, NPEs similarly target courts with efficient IP case handling and relatively lenient damage awards, fully exploiting procedural advantages.

Critically, NPEs operate risk-free. Unlike companies with real businesses, NPEs avoid R&D, production, or sales—they own no products, leaving defendants no counterclaims for infringement. Targets can only passively defend, either investing heavily in patent invalidation proceedings or paying to settle.

NPEs’ only costs are patent acquisitions and legal fees. Victories yield multiples in returns; losses incur nearly no extra damage—a classic “barefoot vs. shod” asymmetry.

For entity ( entity ) companies like Insta360, which must protect markets, reputation, and product launch rhythms, this lopsided game inherently disadvantages them. They can’t afford prolonged litigation or the market losses from sales bans—exactly the leverage NPEs exploit.

Can Insta360’s Defenses Hold?

Industry analyses have long noted that Insta360 faces triple IP pressures: relentless NPE sieges, lingering ITC 337 fallout, and peer commercial patent lawsuits. Now, with domestic NPE litigation opening, the first pressure has shifted from overseas to home turf, stacking risks to unprecedented levels and straining defenses.

Previously, only international legal teams handled overseas cases; now domestic teams must fully engage. NPEs’ core strategy is attrition warfare—wave after wave of lawsuits. Each case demands technical feature comparisons, patent invalidation defenses, evidence collection, and core R&D personnel testifying, alongside hefty legal fees. Over time, legal and R&D teams’ energy is diverted, forcing resources earmarked for new product development and market expansion into litigation instead—a hidden cost far more damaging than settlement fees during Insta360’s critical global expansion phase.

With domestic NPE lawsuits now ablaze, some dismiss the impact due to lower domestic damage awards, but this optimism is misplaced.

A court ruling of infringement could trigger product sales bans, directly disrupting domestic market operations. More critically, it risks setting a precedent—if Insta360 pays to settle domestically, it signals to global NPEs that China’s market is also lucrative for litigation.

The NPE Localization Threat Is Real

This upcoming domestic trial transcends Insta360 alone. It signals a new reality for China’s tech sector: NPE exploitation has spread from overseas markets to the domestic front.

Many domestic firms once assumed “NPEs are an overseas issue; focus on domestic growth,” treating patent trolls as a foreign phenomenon. But as China strengthens IP protection and raises statutory damage caps, patent litigation’s profit potential grows, making NPEs unlikely to overlook the world’s largest consumer electronics market.

Predictably, more NPEs will enter China with acquired patent portfolios, targeting sector leaders for Batch (batch) lawsuits. Familiar with litigation rules and armed with universal patents, their highly standardized tactics pose formidable challenges to domestic firms accustomed to peer competition.

For Insta360, the optimal solution isn’t quick settlement. While seem (seemingly) expedient, it invites greater predation—one payment attracts a pack of wolves.

The true breakthrough lies in using each lawsuit to solidify core patent invalidation defenses, developing a standardized NPE response playbook, raising opponents’ litigation costs, and lowering their win expectations. When NPEs see suing you as low-ROI, they’ll pivot to easier targets.

This domestic NPE trial is both a warning and a test. It reminds all rapidly growing Chinese tech firms that IP defenses must extend beyond overseas markets—home turf requires equally robust fortifications.

After all, when a company grows into a sufficiently mighty tree, the parasites sucking its sap know no borders.
