* Suit filed at German court where other lawsuits pending

* Porsche SE says new lawsuit "unfounded"
BERLIN, Oct 11 (Reuters) - The holding company of Germancarmaker Porsche has received a fresh lawsuit linkedto its 2008 attempt to take over Volkswagen - a213-million-euro ($275 million) claim from the family of adeceased industrialist.
The action from HWO, a firm linked to the family of AdolfMerckle, has been brought at a court in Braunschweig, northernGermany, where Porsche SE already faces damage claims exceeding4 billion euros from investor lawsuits over the same issue.
"We consider this to be unfounded and we will defendourselves," a spokesman for Porsche said on Thursday, confirmingthe lawsuit had been received. German magazine Wirtschaftswochereported the HWO suit earlier on Thursday.
In January, the Merckle family confirmed it would seekdamages from Porsche SE via conciliation proceedings, but theStuttgart-based holding company declined to pay, according tothe Porsche SE spokesman.
Billionaire Adolf Merckle committed suicide in January 2009while his business empire, including stakes in HeidelbergCementand drug wholesaler Phoenix Pharmahandel, crumbled followingbets on VW, increasing debt and a drop in the value ofHeidelbergCement stock.
Plaintiffs have accused Porsche SE of camouflaging itstakeover plans in 2008 and secretly piling up a holding in VW.
When Porsche SE disclosed its stake in October 2008, VWcommon shares surged to 1,005 euros within days, briefly makingVW the world's most valuable company as short-sellers such asMerckle raced to buy back stock they had borrowed to bet that VWshares would drop.
The Braunschweig court dismissed two minor lawsuits againstPorsche SE on Sept. 19, sending a discouraging signal toclaimants including Elliott Associates and other U.S. investmentfunds seeking damages.
