Intellectual Property

The operating entities evaluate on a case-by-case basis how best to use patents, trademarks, copyrights, trade secrets, and other available intellectual property protection in order to protect their products and our critical investments in R&D, manufacturing, and marketing. The operating entities focus on securing and maintaining patents for certain inventions such as equipment used in the production of activated carbon and generation of biomass electricity, while maintaining other inventions such as process improvements as trade secrets, derived from their market-based business model, in an effort to maximize the value of their product portfolio and manufacturing capabilities and reinforce their competitive advantage. The operating entities’ policy is to seek appropriate intellectual property protection for significant product and process developments in the major areas where the relevant products are manufactured or sold. Patents may cover products, processes, intermediate products and product uses. Patents extend for varying periods in accordance with the date of patent application filing and the legal life of patents in the various countries in which the patents are registered. The protection afforded, which may also vary from country to country, depends upon the type of subject matter covered by the patent and the scope of the claims of the patent. The operating entities maintain appropriate information security policies and procedures reasonably designed to ensure the safeguarding of confidential information including, where appropriate, data encryption, access controls, and employee awareness training.
