Last week Intuit, makers of Turbo Tax, sued H&R Block for mimicking its advertising campaign. Block’s ad “copies the physical appearance, dress and mannerisms of the characters in the TurboTax ad, as well as the set, staging and pace of the advertisement,” said Intuit in a statement.

The ad is said to have violated Intuit’s “intellectual property.”

Acrimony betwixt the two companys has been high leading into tax season.

In an earlier skirmish, Turbo Tax got a class-action sued filed against it for failing to disclose that its software couldn’t be loaded onto more than one computer, which turned out to be a big problem if, as it did for many users, the first installation malfuctioncted. Smelling the fart of defeat, H&R Block, which had previously been considering employing the single activation function in its sofwtare, swooped into the fray. The big green block deployed a campaign trumpeting, “Switch Today. TaxCut imports from TurboTax. No product activation required.”

For the gallery, how are you preparing your taxes?
