Pull out your gas-assisted-lawsuit scorecards, because Cinpres Gas Injection Ltd. has filed a new one in Germany against Gain Technologies Inc.
Continuing the years-long, tit-for-tat legal warfare between the firms, Middlewich, England-based Cinpres announced in mid-June that it filed the suit in Dusseldorf Patent Court. Cinpres Gas Injection charges that Gain of Sterling Heights, Mich., is infringing on a Cinpres European patent covering retractable in-mold gas injection nozzles. Cinpres said Gain was advertising a similar type of nozzle on its Web site.
Cinpres issued a news release about the suit the week before NPE 2003 in late June.
Asked for a response at NPE, Gain President Michael Ladney said his company has had retractable nozzles for 10 years.
``If they want to sue us, we've some good answers,'' he said.
Cinpres Chairman Terry Pearson said each of his company's retractable nozzles comes with a license to operate, with no separate licensing fee.
``We are exasperated with receiving threats and lawsuits without good cause from Melea, Gain and PMT [Plastic Molded Technologies Inc.], all controlled by Michael Ladney,'' Pearson said.
Pearson said Cinpres plans to get more aggressive.
``We are determined to see the job finished and are starting to enforce our own intellectual property rights,'' he said.
