After two decades, the Great Gas-Assisted Technology War is over.
Cinpres Gas Injection Ltd. of Middlewich announced Aug. 5 that it has agreed to buy all remaining patents from Gibraltar-based Melea Ltd.
Cinpres also will acquire the Melea trading name.
Melea, which owns all of the patents for gas-assisted molding marketed by Gain Technologies Inc., was placed under liquidation last Nov. 2 by the Gibraltar Supreme Court. Melea owed unpaid legal costs to Cinpres resulting from a British appeals court decision in 2008.
Cinpres Managing Director Jon Butler said the firm is acquiring all Melea patents, which he said are part of a complex web of intellectual property divided between Melea and Gain, run by Michael Ladney.
Under Ladney, Gain Technologies launched a long and often bitter war of words and patent lawsuits against Cinpres.
Ladney could not be reached for comment. The telephone number has been disconnected at Gain Technologies in Shelby Township, Mich.
Cinpres officials said the patent purchase clears the air surrounding gas-assisted technology. In gas-assisted molding, gas, usually nitrogen, gets pumped inside the mold, producing hollow parts as it pushes the melted plastic out against the mold. Gas-assist can cut resin costs, improve surface finish and reduce molded-in stresses in parts.
The positive thing is that there can now be no further confusion Cinpres will be the undisputed owner of all the appropriate gas-assisted technologies, Butler said in a news release. Customers can now buy our technologies without fear of contested claims and counter-claims between Cinpres and Melea or any other party.
Butler said Cinpres has agreed to a price and made the first payment for the Melea patents.
Cinpres gas-assisted technology is covered by more than 40 international patents, according to the company.
