While many cross-border e-commerce sellers celebrate their best-selling products, legal complaints may already be in motion. Recent months have seen a surge in patent infringement lawsuits filed in U.S. courts targeting home goods, outdoor equipment, and personal care products, with notable brands like Dyson leading aggressive intellectual property enforcement campaigns.
For online merchants, overlooking patent considerations often results in store suspensions and frozen assets. Below are five high-risk product categories currently under intense legal scrutiny:
1. Dyson Battery Patent Cases
Dyson has intensified its patent enforcement beyond trademark protection, recently filing three lawsuits (Case Nos.: 23-cv-4401, 23-cv-4379, 23-cv-4342) targeting battery products through legal representation by GBC. The litigation focuses on structural designs of battery packs, particularly internal configurations and connection methods illustrated by solid lines in patent diagrams. Sellers offering third-party replacement batteries compatible with Dyson products must conduct thorough comparisons with patent drawings to avoid structural overlaps.
2. Pet House Design Litigation
A patent enforcement action (Case No.: 23-cv-61347) initiated by a Xiamen-based trading company has been filed in Florida federal court. These cases typically involve unique folding mechanisms or distinctive appearance patents. Merchants should carefully examine whether their product designs substantially resemble the plaintiff's patented features before listing items.
3. Corset Belt Design Patent
Hexin Holding Limited's enforcement action (Case No.: 23-cv-4746) concerning corset belts warrants attention. The case involves U.S. Design Patent USD981078S, granted in March 2023, which protects specific texture patterns, fastener arrangements, and overall silhouette characteristics. Given the rapid product iterations in this category, sellers must verify their products' design details against the patent specifications.
4. Roof Rack Crossbar Mechanism
Initiated by Xingpin Kuang (Case No.: 23-cv-4800), this lawsuit targets mechanical structures and mounting mechanisms of roof rack crossbars. Patents in this outdoor equipment category frequently focus on the engineering of connection components. Products bearing close resemblance to major brands' installation systems or cross-sectional designs face elevated infringement risks.
5. Bendable Moss Pole Technology
SIMPLY MOSSY ART INC's lawsuit (Case No.: 23-cv-6434) has drawn attention from gardening product sellers. The bendable moss pole serves as a plant support tool with DIY shaping capabilities, protected by patents covering its internal support structure's bending technique and material encapsulation method. Both functional and design patents create substantial barriers against imitation products.
Compliance Recommendations: Unlike trademark infringement, patent violations often reside in microscopic product features. Merchants should conduct professional patent searches during product selection, employing "solid line" drawing comparison methods to assess infringement potential. Upon receiving legal notices, immediate sales suspension and consultation with intellectual property attorneys are imperative. Cross-border commerce demands compliance-first operations—only through respecting intellectual property rights can businesses achieve sustainable growth.
