Nintendo doesn't have a 100% record of winning patent cases, but it does win the majority. It often comfortably sees off particularly frivolous claims on broad technology patents, too - notable defeats have generally come against companies with which Nintendo has previously worked or liaised, not businesses that hoover up patents in the hopes of pay-offs.

This time around Secure Axcess has been seen off, with ten separate patent aspects that placed claims on the DS and 3DS families dismissed. Secure Axcess is a business that offers 'Patent Evaluation Services', so the outcome of the court case suggests that it was somewhat trying its luck.

This win has been announced not long after another patent case related to Nintendo handhelds was thrown out, so Nintendo's legal team is certainly earning its fees at the moment.
