Valve blocks Dbrand's Companion Cube skin for Steam Machine

At a glance:

• Valve ordered Dbrand to remove the Portal-themed Companion Cube conversion kit for the Steam Machine because it lacked a license.
• Dbrand refunded all pre-orders by end of day and is left with warehouses full of the unsold accessory.
• Dbrand plans to continue selling other Steam Machine skins, but none will match the Companion Cube's detail.

Valve pulls the plug on Companion Cube

Valve contacted Dbrand shortly after the Companion Cube skin went live earlier this month, demanding its removal from the website and all marketing materials. The accessory, a conversion kit that replicated the iconic Weighted Companion Cube from the Portal series, had been marketed as a premium add‑on for the upcoming Steam Machine. Valve's intervention came despite the product's strong early sales, which Dbrand said made it the second‑fastest‑selling item in its history behind the Switch 2 Killswitch.

In a Reddit post, Dbrand disclosed that it attempted to negotiate a retroactive license, arguing that the kit might be one of the most anticipated Steam Machine accessories. Valve declined the request, and the product page now redirects visitors to the Reddit announcement. The decision underscores Valve's strict control over its intellectual property, even for fan‑driven hardware projects.

Dbrand's development effort and sales

Dbrand revealed that the Companion Cube conversion kit consumed more than a thousand hours of engineering time and required specialized tooling to mimic the in‑game prop's geometry and surface finish. The company described the accessory as more than a simple skin, noting that it involved custom molds, precision CNC work, and a multi‑step finishing process to achieve the cube's distinctive look.

The kit's popularity was immediate: Dbrand claimed it became the second‑fastest‑selling product in its catalog, trailing only the Switch 2 Killswitch. The firm also said it now holds warehouses full of the completed units, a costly inventory that cannot be sold without Valve's permission. This stockpile represents a significant financial loss for a company that typically operates on a made‑to‑order model.

Licensing dispute and Valve's response

The core of the conflict is intellectual‑property ownership. Portal, the franchise that introduced the Companion Cube, was released years before the Steam Machine concept existed, but Valve retains all rights to the game's assets and trademarks. Dbrand admitted it launched the product without securing a license, assuming the community‑driven nature be tolerated.

Valve's swift legal action — requesting removal within days of launch — signals a low tolerance for unlicensed merchandise tied to its hardware platform. The refusal to grant a post‑launch license, despite the product's commercial success, suggests Valve prefers to control the ecosystem of official accessories rather than open it to third‑party reinterpretations of its iconic imagery.

Future skins and what's next

Dbrand confirmed it will continue to offer a range of generic skins for the Steam Machine, but acknowledged they will lack the cultural resonance and engineering depth of the Companion Cube. The company hinted that future designs may avoid direct references to Valve's game IP to prevent similar takedowns.

For Steam Machine buyers, the cancellation means one less officially themed customization option at launch. Observers note that Valve's stance could shape the broader accessory market, encouraging makers to pursue original designs or seek formal partnerships early. The episode also highlights the risks for accessory vendors that invest heavily in tooling before clearing IP rights.
