If we've learned anything from the patent wars it's that lawsuits beget lawsuits, and Red and Sony's budding spat is no exception. In response to allegations that Sony's F5, F55 and F65 cameras violate a pair of Red camera patents, the Japanese manufacturer is filing a suit of its own. The company says that the Red One, Epic and Scarlet cameras infringe on seven Sony patents, and is seeking damages and a sales injunction on the offending products. Accessories like the REDMOTE are headed to the courtroom, too. Sony's demands aren't as specific as Red's, which originally sought to have its competitor's camera's destroyed -- but we'll sure things will heat up when litigation starts. Take a peek at Sony's brief statement after the break.
