Big Players in the Earphone and Headphone Industry

The First In-Ear Headphones Patent

French engineer Ernest Mercadier was granted the patent for the first-ever in-ear headphones way back in 1891. His invention was initially designed to be used by telephonists; they even had earbuds to prevent interference from external noises.

Ernest Mercadier’s Patent: US454138A

Famous Headphone and Earphone Design Patent Infringement Case: Beats v. Yamaha

Back in February 2013, Beats Electronics, LLC (Beats) filed a lawsuit against the Yamaha Corporation of America (Yamaha), in the Central District of California, USA, claiming infringement of Beats’ design patents, along with infringing upon Beats’ trade dress protection rights.

As you may already know, here at InQuartik, we deal with patents, so it’s worth mentioning that Trade dress is legal terminology that refers to the overall appearance of a product or its packaging that exhibits its source to consumers.
As with patents, businesses can register their trade dress with the USPTO.

Registering their trade dress protection enables companies to guard their rights in federal court against trade dress infringement. In order to get this trade dress protection, the trade dress needs to be “inherently distinctive,” and the use by others must be likely to mislead or confuse buyers.

Additionally, the complaint also included a demand that the court should hand down a judgment that orders Yamaha to surrender and destroy every last one of the claimed infringing headphones. Not only that, but Beats also demanded the destruction of any materials representing the alleged infringing headphones. Furthermore, the complaint also asked for a jury trial on all matters.

The complaint stated that the attorney for Beats gave notice to Yamaha in November 2012, declaring that it believed the Yamaha Pro 300, Yamaha Pro 400, and Yamaha Pro 500 headphones infringe upon Beats’ design patents, along with infringing upon Beat’s trade dress protection rights.

The complaint also asserted that the Pro 300, Pro 400, and Pro 500 headphones were:

“Knock-offs of Beats’ world-renowned ‘Studio,’ ‘Solo,’ and ‘Wireless’ headphones.”

The complaint claimed that Yamaha had:

“Infringed Beats’ famous and distinctive trade dress and committed unfair competition.”

The design patents that Beats’ claimed were infringed upon are D632,668 and D552,077, claiming an audio listening system and a headphone, respectively.

Beats went on to claim that:

“Consumers appreciated the design, as well as the sound quality, of the Beats Headphones and began wearing the Beats Headphones around their necks as a fashion accessory even when not listening to music.”
