One of the Companys most valuable assets is its intellectual property including patents, trade secrets, trademarks, service marks, and copyrights. Employees must safeguard the Companys intellectual property by using it only in ways that are consistent with applicable law and by not allowing third parties to use the Companys intellectual property without appropriate legal protections approved by Acuity Brands counsel. The Company also will not permit the unauthorized use of the intellectual property rights of others. Inventions and ideas of employees, which are created by employees in connection with the Companys business, research, development, design, or manufacturing efforts, are the property of the Company.
