Experience at Work

Drey is a corporate, intellectual property and litigation attorney, counseling and assisting businesses and individuals in a wide-variety of litigation, business/transactional, real estate, employment, risk management, governance and intellectual property matters.

Drey practices in both federal and state trial courts.  Many of his business litigation matters involve fiduciary and shareholder disputes, real estate, 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 practice, Drey assists businesses in the protection of their brands and intellectual property portfolios through trademark and copyright infringement litigation, 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 U.S. Copyright Office and negotiates intellectual property agreements (including concurrent use and coexistence agreements).

Drey also represents for-profit and non-profit businesses and individuals in commercial and high-dollar 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 exemption. Drey is the author of, a blog discussing Missouri commercial real estate tax appeals and non-profit property tax exemption issues.
