Recent weeks have seen an uptick in legal actions targeting California-based footwear company Skechers, with Utah-based HandsFree Licensing Labs (HFL) filing a lawsuit alleging patent infringement. This latest development adds to a growing list of accusations against the company, which has repeatedly been criticized by competitors for copying designs without proper intellectual property recognition.
The Case at Hand: HFL v. Skechers
HandsFree Licensing Labs, a Utah-based company known for its innovative shoe technology designed for elderly individuals, disabled users, and those with motor skill difficulties, has filed a lawsuit in the Eastern District of Texas. The complaint alleges that Skechers’ Hands Free Slip-In technology, which constitutes over one-third of the company’s product lineup, infringes on HFL’s patented technology.
The Hands Free Slip-In technology, introduced with significant marketing ahead of Super Bowl LVII, incorporates a unique heel pillow and elastic upper elements that HFL claims were misappropriated from its patented designs. These technologies aim to help users easily slip into shoes without lacing them - a feature particularly beneficial for individuals who may struggle with traditional shoelace fastening.
Skechers’ Alleged Copying of Competitor Innovations
This is not the first legal action against Skechers. Major footwear brands, including adidas and Nike, have both accused the company of building its business model around copying competitor designs. A 2017 court order in the District of Oregon suggested that orders for knockoff versions of popular adidas shoes were likely initiated by Skechers’ CEO, Robert Greenberg.
HFL’s lawsuit highlights the profitability of this alleged copying. In May 2024, the Greenberg family sold their stake in Skechers for $1.1 billion following a $9.5-billion sale to Brazilian investment firm 3G Capital. The complaint claims that Skechers’ success with the Hands Free Slip-In technology - introduced with a high-profile marketing campaign featuring celebrities like Snoop Dogg - is largely based on HFL’s original innovation, which began with Kizik’s hands-free sneakers in 2017.
Key Patents at Stake
HFL’s lawsuit focuses on several patents, including:
- U.S. Patent No. 11633006 and related patents, covering rapid-entry footwear with a stabilizer and elastic element.
- U.S. Design Patent No. D1037641, which protects the overall design of the footwear.
The accused Skechers products include models such as the Arch Fit, Max Cushioning, Ultra Flex, Glide-Step, GO WALK, GO RUN, Summits, D’Lites, Work, and Kids/Youth lines - many featuring elastic or stretch laces and mesh synthetic upper elements. These features are alleged to infringe HFL’s patented technology.
Venue Considerations
The Eastern District of Texas, known for its high volume of patent infringement cases, has been a key venue for these lawsuits. HFL’s complaint cites Skechers’ substantial business activities within the district, including its store locations and partnerships like the Houston Marathon, as evidence of proper venue. This is not the first time Skechers has faced legal action in this jurisdiction - precedent exists in at least two prior lawsuits filed against the company in the same district.
Relief Sought
In addition to injunctive relief to halt the alleged infringement, HFL seeks damages under 35 U.S.C. § 284 and is asserting that Skechers’ actions were willful, potentially qualifying for an exceptional case determination under 35 U.S.C. § 285. The company also requests an award of attorney’s fees.
Broader Implications
This case underscores the complexities of trademark and intellectual property law in the footwear industry. The allegations of copying competitor designs raise important questions about trademark confusability - how closely can one brand’s design mimic another without infringing on intellectual property rights?
For businesses, these cases serve as a stark reminder of the need for robust trademark monitoring programs to detect and address potential infringements early. Companies like Skechers must navigate the fine line between innovation and copying, ensuring their designs are original and legally sound.
