Drone law practices may finally be taking off.

After an initial flurry of activity that saw the proliferation of drone law practice groups several years ago, the anticipated steep trajectory of drone-related legal work failed to come to pass as regulations on the commercial use of the unmanned aerial vehicles restricted industry growth. But with the unmanned aerial vehicle industry continuing to evolve, law firms with drone practices are finally getting off the ground.

“There's far more work now than there was three years ago,” said Michael Drobac, a senior policy adviser at Akin Gump's emerging technologies group and director of the Small UAV Coalition—an organization whose members include Amazon.com Inc., Alphabet Inc.'s Google, Intel Corp., Verizon Communications Inc. and other manufacturers and operators of unmanned aerial vehicles. “This industry is far more complex that most people originally thought.”
