In 1926 Abraham D. Caesar and Charles Rivise founded the firm. Together they practiced patent, trademark and copyright law and authored a four volume treatise on patent law entitled Interference Law and Practice that has been cited by the courts in hundreds of cases throughout the United States. They also authored a book entitled Patentability and Validity, which for more than thirty years was used as a textbook in law schools teaching patent law. As a result of this heritage, the firm of Caesar Rivise has been a leader in the field of patent, trademark and copyright law (now known as Intellectual Property law) by protecting and promoting the development of creative ideas and the people who create them. The attorneys of the firm are imbued with a spirit of collegiality and enthusiasm for their profession, their clients and the community. The attorneys have backgrounds in the fields of chemistry, chemical engineering, pharmaceuticals, biotechnology, mechanical engineering, materials science, electrical engineering, computers, the Internet and Information Technology. This combination of varied technical skills among the attorneys creates a synergistic energy that is maximized when fulfilling each clients needs.
