Apple countersues headphone maker Koss in patent infringement battle — Apple World Today

In a new filing with the U.S. District Court for the Northern District of California San Jose Division, Apple “one-ups” Koss’ five-count lawsuit with one containing six counts, notes AppleInsider. While the first details an alleged breach of contract, the other five each declare the tech giant didn’t infringe on each of five patents that Koss is using in its own complaint.

Apple seeks to stop Koss from using the discussions raised under the confidentiality agreement in any lawsuit, to declare Apple doesn’t infringe on the identified claims, a recovery of “reasonable attorneys’ fees,” and any other relief. A trial by jury is demanded.

Koss Corporation is an American company that designs and manufactures headphones. Headquartered in Milwaukee, Wisconsin since 1958, the company invented the first high fidelity stereophones.
