SAN FRANCISCO — Plaintiffs attorneys netted less than half of what they hoped for in fees and costs Monday after settling a shareholder derivative suit against a maker of blood analysis technology.

U.S. District Judge Yvonne Gonzalez Rogers awarded the attorneys with Kessler Topaz Meltzer & Check and Saxena White $543,000 in fees and $36,400 in costs, a far cry from the $1.6 million in fees and $51,200 in costs requested.
