With the implementation of various measures for environmental protection and energy conservation, new energy-saving and non-burning building materials have been widely used and become a new territory for people to start their own businesses. You can get rich by producing these energy-saving building materials or make building materials production equipment to get rich. And those who are eager to start a business, but not so much money, if they use the patents of new building materials that are ineffective, their entrepreneurial costs will be greatly reduced.
Those who have a little knowledge of patent knowledge will know that invalid patents will lose the protection of the law, and they can be used for their own purposes at a low cost, so that their value can be exerted. Those ineffective patents generally refer to the fact that the patentee has not continued to pay the patent management fee or for other reasons. In addition, some foreign patents can also be used, as long as the products produced are not sold to their patent protection scope, because many foreign patents do not apply for China's protection scope. For example, the patent for ash composite composite brick for construction, the patent for fly ash building materials, the patent for fly ash without burning steam-free building load-bearing brick, the patent for fly ash four brick-free, and the patent for non-burning hollow brick machine. Non-burning brick molding machine patents and so on. These new building materials patents are good test items.
