Stephen Korniczky and Sheppard Mullin Richter & Hampton made good law for smartphone makers a year ago on the valuation of standard-essential patents. Now, they’re bringing those same arguments about fair, reasonable and non-discriminatory (FRAND) royalties to new industries: automotive technology and the industrial internet of things.

On Tuesday, Sheppard sued IP powerhouse InterDigital Inc. on behalf of u-blox, a Swiss developer of cellular modules used in automobile navigation systems and other connected devices. U-blox accuses InterDigital of demanding “exorbitant non-FRAND” royalties for patents that are essential to practicing the 2G, 3G and 4G wireless standards.
