Lawsuit Settled Over Pollution Cleaner Device : Patent: Costa Mesa’s Parker Automotive and Triangle Special Products agree to work together but decline to reveal more about their arrangement.

Parker Automotive Corp. said Friday that a patent infringement suit filed against it last year by Triangle Special Products Group has been dismissed as a result of an agreement by both firms.

The suit, filed in U.S. District Court in Los Angeles, alleged that one of Parker’s automotive pollution-cleaning machines infringed on patents held by the division of Triangle Corp. of Stamford, Conn.

With the dismissal, each party will pay its own legal costs. The costs will not have an impact on Parker’s 1990 financial performance, said Diane Parker, corporate vice president.

She said Triangle and Parker have agreed to work together but declined to reveal more about their arrangement.

In a separate announcement, Parker said it has signed an exclusive distribution agreement with a Saudi Arabian company for sales of its cleaning systems for internal combustion engines.

The Saudi Arabian distribution deal, with Diyar Corp. of Riyadh, was actually signed in July but was held up by the Aug. 2 Iraqi invasion of Kuwait and the subsequent turmoil as troops from the United States and other countries poured into Saudi Arabia to help defend it against a possible Iraqi attack.

In announcing the agreement Friday, Parker released a statement in which Diyar vice president Adnan Amin said that “events in the Mideast have more or less stabilized to the point that it is business as usual for Diyar.”

Amin was not minimizing the seriousness of the Persian Gulf crisis, Diane Parker said: “He was just saying that Diyar has determined that it can continue doing business.”

The one-year agreement, with a five-year renewal option, calls for the Saudi firm to buy at least $1 million yearly in CarbonClean products, Parker officials said.

Diyar distributes engine-related machinery and tools throughout Saudi Arabia and other Persian Gulf countries and provides maintenance services to government agencies and private companies that operate irrigation and oil field equipment, Parker said.

In his statement, Amin said he expects the CarbonClean system to be especially valuable in Saudi Arabia as a method for servicing gasoline and diesel engines in remote desert oil and irrigation stations, without having to open the engines and expose them to sand and dust.
