Lotus Racing has been granted full indemnity from Aerolab/Fondtech in the aerodynamic design company's ongoing court action with the Force India team.
Force India is seeking damages from Fondtech/Aerolab because it believes it copied the team's wind tunnel design model in the work it did helping out Lotus.
Aerolab/Fondtech has constantly denied claims that it passed on any data to Lotus and, although it has called on the UK-based team as a co-defendant in the case, the team has received assurances that it is not involved in the claim.
A Lotus spokesman confirmed on Tuesday that it was aware of the legal action between Aerolab/Fondtech, but confirmed his outfit was exempted from the matter.
"Lotus Racing has been joined as a co-defendant in civil proceedings which are principally between Force India and Aerolab/Fondtech," said the spokesman. "These proceedings do not allege any wrong doing on the part of Lotus Racing.
"Aerolab/Fondtech vigorously denies any wrong doing and has provided Lotus Racing with a full indemnity in relation to the claim."
