Shareholder and Associate General Counsel

Drey A. Cooley


Experience at Work

Drey represents businesses and individuals in a wide variety of business, real estate, construction and intellectual property disputes in state and federal trial courts. Many of his business and real estate litigation matters involve fiduciary disputes, commercial fraud, construction/mechanic’s liens, unfair competition issues and contract disputes.

Drey is also an experienced appellate attorney, representing clients in civil and criminal appeals in front of a variety of state and federal appellate courts, including successfully achieving a reversal on behalf of a firm client in a widely publicized matter in front of the Missouri Supreme Court. His appellate practice is not limited to briefing and oral argument. Instead, it includes representation and/or consultation with attorneys regarding jury instructions, summary judgment briefing and post-trial motions, as well as the preparation of petitions for writs of mandamus and prohibition.

In his intellectual property litigation practice, Drey assists businesses in the protection of their intellectual property portfolios through trademark and copyright infringement litigation in state and federal courts, as well as in actions in front of the Trademark Trial and Appeal Board (TTAB). With a background in web development, Drey has a particular interest in litigation concerning domain names, e-commerce and internet-based trademark and copyright disputes. Aside from litigation, Drey also applies for, registers and prosecutes trademarks and copyrights on behalf of individuals and businesses before the United States Patent and Trademark Office (USPTO) and various state trademark offices, including Missouri.

Drey also represents for-profit and non-profit businesses and individuals in commercial and high-value residential property tax appeals in front of County Boards of Equalization and the Missouri State Tax Commission. Many of these appeals involve claims of overvaluation or, with respect to non-profit corporations, tax exemptions. Drey is the author of MissouriRealEstateTaxAppeals.com, a blog discussing Missouri commercial real estate tax appeals and non-profit property tax exemption issues.
