"Green" patents, or those relating to clean energy, reductions in greenhouse gas emissions, and other environmentally-driven technologies are reportedly up sharply. The number of green patents were up to 1,068 in 2007 from only 424 in 1998.
One important aspect of developing these businesses is protecting intellectual property for new ideas and processes that are created. Many of the new clean tech companies may produce intellectual property that can be protected through patents. Clean tech entrepreneurs should be mindful of the intellectual property aspects of their developing businesses and be sure to consult with the right professionals to ensure their new inventions are protected. Without this protection, the value of the business may be damaged and the ability to raise capital may be diminished.
