Tianjin Steel Pipe Group Co., Ltd. has been granted national authorization for two invention patents.
2010-11-23
Recently, the technology center of the group company received a written notice from the National Patent Office that two invention patents have been granted national authorization. This marks a new achievement for the group company in the protection of independent intellectual property rights.
The two patents authorized by the National Patent Office, 'Method for Flattening Transverse Impact Samples of Small Diameter Seamless Steel Pipes' and 'Heat Treatment Process Method for High Strength Toughness Steel Pipes', are technical know-how summarized and explored by the technology center's research team during the development of high-strength and high-toughness perforating gun barrels. Since some key technologies involve core secrets in the production and testing processes of high-strength and high-toughness pipes, in order to better protect the company's independent intellectual property rights and enhance the group's core competitiveness in high-end products, the technology center promptly applied for national patent protection for these two key technologies. After more than a year of rigorous review, these two technologies were found to be novel and creative, not overlapping with existing patents and technical materials, and were granted authorization by the National Patent Office.
