Real-Life Patent Infringement Cases:

A bra can be covered by a design patent or a utility patent. A design patent is concerned by how an invention looks and feels, whereas a utility patent, on the other hand, will protect any unique functions that the invention may have.

Design Patent Infringement Case: Lululemon vs. Under Armour

On July 7th, 2017, Lululemon Athletica, the sports and leisurewear company, filed a patent infringement suit against Under Armour. Lululemon alleged that three of Under Armour’s sports bras had infringed upon design Lululemon’s design patents. In Particular, Lululemon declared that the interwoven bra strap design of the Under Armour sports bra’s in question was highly similar to the designs that were already protected by patents that Lululemon had filed back in 2014 and 2016.

According to the filing, Lululemon sought injunctive relief to stop Under Armour from further infringing on the design patents, damages or disgorgement of Under Armour’s profits from its infringing activities, prejudgment interest, and costs and attorneys’ fees.

The filing stated that:

“[A]n ordinary observer will perceive the overall appearance of the designs of the infringing products to be substantially the same as the overall appearance of the designs of the patent-in-suit.”

According to Retail Dive, the online outlet for retail news and trends, Under Armour’s response to the claims was:

“Under Armour as a leading brand in the sports performance market takes the intellectual property rights of others very seriously.”

In October of 2017, both companies jointly asked a judge to dismiss the lawsuit in a federal court in Delaware, no financial or settlement details were disclosed.

Lululemon has limited opportunities to attack competitors in court as it doesn’t own any patents in the technology, fabrics, or processes that make its products. Lululemon’s design patents are its strongest asset.

Lululemon has amassed a total of 31 design patents on various athletic apparel items. The company appears to be using the protection to deflect rivals by threatening and proceeding with patent litigation.

Utility Patent Infringement Case: Stretchline Intellectual Properties Ltd. vs. H & M Hennes & Mauritz LP

Stretchline won against H&M after they stole a patented invention of a component of their bras. The legal battle lasted for four years.

Stretchline created a technology that stopped bra underwiring from piercing through bra material. It was later discovered that H&M had stolen this patented invention and had used it in their bras. In fact, the technology called Fortitube was found to have been used in twelve of H&M’s ranges following test purchases in 2011.

H&M did not have a license to use the patented invention, so Stretchline issued a lawsuit. The case was settled the very same year, and an agreement was put in place so that H&M could no longer sell garments that infringed upon the UK patent.
