Shares of IP-focused investment company MDB Capital Holdings began trading on the NASDAQ last week—a development of particular interest to those following the evolution of Arizona’s Alternative Business Structure program, under which nonlawyers can own and operate law firms in that state. MDB is the corporate parent of patent database and search company PatentVest, Inc., which earlier this year received approval from Arizona’s Committee on Alternative Business Structures to become an “end-to-end law firm”.
