Sports shoe company Pony is suing giant rival Nike over claims that it infringed copyright in the execution of its recent "V for victory" online marketing campaign.

Pony has registered a trademark infringement complaint with the Federal Court of San Diego, alleging that the campaign's "V" motif was an imitation of its chevron design, used on the company's sports shoes.

Pony, which is seeking financial damages and a court order banning future use of the slogan, claims that it "is identical or virtually identical to the registered trademarks owned by Pony".

Nike failed to return just-style's requests for comment on the case, but the company was reported in the US as saying that the case was "without merit", and that it would defend it.

The "V for victory" online marketing campaign featured Spanish world tennis number one Rafael Nadal and Argentinian footballer Sergio Aguero.
