King is the principal reason. . . .In [one] case . . . the company threw a ton of money and resources against us, with a large trial team . . . but Jonny simply ripped them apart with his courtroom abilities and his sharp analysis of trademark law supporting our case.  He’s so smart and really understands our business, but is also incredibly unpretentious and down-to-earth.”
