SAN FRANCISCO — Wielding the U.S. Supreme Court’s recent decision on fee-shifting in patent cases, Apple Inc. and Hewlett-Packard Co. are seeking a combined $3.7 million from a company they describe as a serial-filing nonpracticing entity.

“This case ‘stands out’ because—long after it was clear that Linex had no valid claim to the technology at issue in this case—Linex continued to press its weak case through serial litigation in the hopes of extracting a settlement,” the two companies argue in Linex Technolgies v. Hewlett-Packard, before U.S. District Judge Claudia Wilken.
