Apple responds to AirPods patent infringement suit by countersuing Koss Corporation for breach of contract and breaking a confidentiality agreement
On July 23, Patently Apple posted a legal report titled “Koss, an American Pioneer in Headphones, has filed a Five-Count Patent Infringement Lawsuit against Apple.”
Context & Ripple Effects
In late July 2020, Milwaukee headphone maker Koss filed a five-count patent infringement suit against Apple, Bose, and three other companies over AirPods-style earphones — a rare instance of a legacy audio brand taking on a trillion-dollar hardware giant. Apple's answer is not just a defense but a counterattack: it alleges Koss itself breached a contract and a confidentiality agreement, implying prior dealings whose terms now cut both ways.
The move echoes Apple's own playbook from the other side of the table — when Qualcomm faced Apple's licensing suit, it answered with a countersuit of its own, including claims about iPhone modem performance. The eventual outcome here matters for how small IP holders price future fights against Apple: the dispute ultimately ended in an undisclosed settlement two years later.
First-order effects
- Apple flips from defendant to accuser: Koss must now litigate on two fronts, defending its AirPods patent claims while answering allegations that it violated a confidentiality agreement.
- The breach-of-contract claim signals Apple believes prior confidential dealings with Koss exist — turning what Koss framed as pure patent enforcement into a fight about the terms of their past relationship.
Second-order effects
- Co-targets Bose and the other accused companies gain a template: Apple's countersuit suggests the infringement claims rest on disclosures or agreements that could be challenged across the whole suit rather than patent-by-patent.
- For Koss, a company far smaller than Apple, the added front raises the cost of pressing the case — increasing the odds it settles for terms short of full patent validation, as later happened.
Third-order effects
- Countersuit-as-defense is becoming the standard posture for large tech companies facing patent claims from smaller holders, shifting these disputes from 'is the patent valid?' to negotiated outcomes shaped by relative legal budgets.
- If the pattern holds, legacy audio and component firms holding foundational patents face a structural choice: license quietly or risk a multi-year fight they likely cannot outlast.
The trend: Big tech's default response to patent suits from smaller IP holders is increasingly the counterclaim, converting patent disputes into contract-and-negotiation battles resolved by settlement rather than courtroom victory.
