Oeneo successfully defends super-critical challenge

Oeneo, manufacturer of technical closure DIAM, successfully defended a challenge to its patented super-critical technology in the European Office of the Patent in München yesterday.

The challenge was filed by cork producers against Oeneo and the Government owned French Atomic Agency CEA, which jointly own the exclusive rights to the patented DIAM super-critical CO2 process. Objectors had challenged DIAM’s rights to the super-critical technology.

“This recent challenge is yet another positive validation of the Diamant process, and of the DIAM closure in itself, highlighting the inferior nature of other cork based closure solutions," DIAM commercial director Dean Banister said.

"As custodians of the Diamant process we are exploring opportunities to share the technology with selected industry partners. That said, of utmost importance to Oeneo is the integrity of the Diamant process – we need to ensure the technology is used in a responsible manner to continue to deliver efficient closure solutions to the global wine industry," he said.

The Diamant process, which has been scientifically proven to eradicate detectable levels of TCA and other undesirable compounds, has been used since 2003 to produce and sell nearly 800m DIAM closures that are not only TCA free but also offer varying levels of Oxygen Transmission Rates (OTR) and a mechanical sealing guarantee of a minimum of two, five or ten years.
