JAMES E. MAGLEBY practices in all areas of intellectual property and complex civil and commercial litigation. Mr. Magleby’s litigation and trial experience includes cases involving trade secrets, patents, trademarks and unfair competition, the Lanham Act, trade dress, real property and real estate, construction, partnership and business dissolutions, commercial collections, securities, landlord-tenant disputes, and non-competition and non-circumvention agreements.

Mr. Magleby also has extensive experience in seeking and resisting expedited relief, particularly in intellectual property, false-advertising and trade secret cases, including temporary restraining order (TRO) and preliminary injunction hearings.

Mr. Magleby has been practicing for more than 20 years, and has obtained notable major verdicts and favorable rulings for clients in the courtroom and arbitration. For example, he represented Utah-based ClearOne Communications, Inc. in a two-and-a-half week jury trial, resulting in a verdict of approximately $10.5 million for theft of trade secrets and related claims. Shortly thereafter, he represented a number of parties in a complex business theft case, obtaining approximately $1.3 million in a bench verdict. Mr. Magleby represented a partner in La Caille Restaurant in a breach of partnership and fiduciary duty case, obtaining a $4.7 million unanimous verdict from a Salt Lake County jury. Mr. Magleby was one of two firm partners who obtained a complete dismissal of over $27 million in claims against a client, in a confidential two-week arbitration held in New York City. Mr. Magleby was co-counsel with Magleby Cataxinos & Greenwood partner Peggy A. Tomsic in a more than five-week jury trial, in which the firm won a unanimous verdict of over $133 million for the firm’s clients in a theft of trade secret, breach of Confidentiality Agreement, and breach of fiduciary duty case. The jury verdict was affirmed by the Utah Supreme Court in May 2016. Mr. Magleby secured settlement of $45 million for Utah-based ClearOne, Inc. against investment bank UBS Financial Services, Inc. after a two-week arbitration before a three-member panel, but before a decision.

Prior to forming Magleby & Greenwood, P.C., the predecessor firm to Magleby Cataxinos & Greenwood, Mr. Magleby worked for a number of Utah’s premier law firms, including Burbidge & Mitchell; Jones Waldo Holbrook & McDonough; Berman, Tomsic & Savage, and Ballard Spahr.

Mr. Magleby is A/V rated by Martindale Hubble, the highest rating available for an attorney. Mr. Magleby has been consistently voted by his peers throughout the state as one of Utah’s “Legal Elite” every year for more than a decade, as published in Utah Business Magazine.
