Global 3D printing patent applications continues to grow, China ranks second

If stereolithography 1984 Charles W Hull patent application as a starting point, 3D printing technology to date has been 35 years of development. In 35 years of development, 3D printing technology from earlier as a rapid prototyping technology, has become a manufacturing technology. In the process of development, scientific research institutions worldwide, 3D printing companies, manufacturing companies continue to use technology iteration, and a large number of applications and 3D printing materials, equipment, related technology patents. Especially in the last decade , the global 3D printing number of patent applications has been rapid growth, according to IPlytics patent data from 2007 to February 2019, were retrieved associated with 3D printing Patent 95 CONTROL ENGINEERING China Copyright , 302, patent family 43,418 entries. Patents filed in the United States up to Control Engineering Copyright , followed by China and Europe. As can be seen from the data IPlytics published, since 2007, the global number of patent applications related to 3D printing to grow year by year, 2018, amounted to 24,245 items.

patent filed in China in 2018 only disclosed in 3DThe number has reached 9,932 items print patents, including the application of US companies in China or European companies, such as GE, Ford, Siemens, MAN Diesel and turbine Europe AG and Airbus. In these patents, the number of Chinese invention patent 6 In 2018 CONTROL ENGINEERING China Copyright , 457. 3D printing patent relates to 3D printing equipment, materials, processes and applications. For example: the Shanghai Jiaotong University and the Laser Technology Co., Ltd. Hai Hanbang United Airlines filed “an ultrasound-assisted liquid bimetallic Direct 3D printing apparatus and a printing method”; Nanjing University of Aeronautics and application of particle reinforced situ preparation SLM self TiAl intermetallic compound method; Xi application Laid-platinum force “an aluminum matrix composite powder material and additive manufacturing equipment for a” composite material produced by this technique improves the physical properties yl solve the nano particles in the matrix reinforcement uneven distribution of technical problems; Guangzhou, the three-dimensional titanium materials Limited for a series of 3D printing orthopedic implants patents, including patents related to 3D printing artificial vertebral body that it has successfully conducted clinical applications. Coverage metrics and technology-related indicators by 3D printing market IPlytics patent, patent portfolio can be a preliminary analysis of the strengths, weaknesses and positioning.
▲ Table 1 3D print patent indicators
coverage of market value reflects the company’s strategic patent application internationalization of the global breadth and protected by law. In addition, the high coverage of market values ​​reflect the applicant’s patent high perceived value. The more countries a patent application is filed, the higher the invention has the potential international market. As shown in Table 1, the top 10 applicants Patent Patent 3D printing all compositions have a wide range of international coverage (higher than average score 1). Technology-related indicators is the number of patents cited, high-tech correlation value can be considered as the leading technology in specific market segments. As shown in Table 1, a combination of 3D printing Patent top 10 of the patent owner with high technological relevance (values ​​greater than 1, representing the above average). 10 were in the previous patent applications, the most relevant scoring technique GE, Stratasys and Harvard University. According to IPlytics data, 3D printing patent litigation between 2000 and 2018 occurred in the United StatesUp from 155 cases. Figure 5 shows the number of patent litigation in the 2007-2018. In the 155 patent litigation, patents total of 71 (45%) has been transferred (reassigned).

3D printing technology of the future will increasingly rely on proprietary technology, the development of effective patent strategy will help enterprises to cope with a sharp increase in the number of patent applications and patent litigation. In this regard, the proposed 3D printing business person in charge of patent ponder the following questions: ● 3D printing patent number continues to increase, companies should consider royalties and license fees payment; ● corporate executives should not only monitor 3D printing patents, patent should be monitored data transfer of patent litigation or data; ● senior management should monitor the patent dynamic 3D printing patent market for enterprise advocates royalties patent or patent portfolio.
