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 development process CONTROL ENGINEERING China Copyright , research institutions worldwide, 3D printing companies, manufacturing companies continue to use technology iteration, and a large number of applications related to 3D printing materials, equipment, technology patent. Especially in the last decade, the global number of 3D printing has been rapid growth in patent applications CONTROL ENGINEERING China Copyright , according to IPlytics patent data from 2007 to February 2019 Copyright Control Engineering were retrieved related items 3D printing Patent 95,302, 43,418 items patent family. Patents filed in the United States the most, followed by China and Europe. The number of patent technology patent applications affect the competitiveness of enterprises 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.

Figure 2 shows that the number of patents the top three are the General electric company (GE), Hewlett-Packard (HP) and United technologies Corporation (United technologies), wherein at 2,516 GE patents topped the list items as 3D printing. In the research institution, 3D printing, the number of patents in the first row of Harvard University.

According 3D science ValleyMarket analysis, patent filed in China, the number of 3D printing patent only disclosed in 2018 reached 9,932 entries , including the application of US companies in China or European companies such as GE, Ford, Siemens, MAN diesel and turbine Europe AG, Airbus and so on. In these patents, the number of Chinese invention patents amounted to 6,457 items in 2018. 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 problem uneven distribution; Guangzhou-dimensional titanium materials Limited for a number of 3D printing orthopedic implants Patent , comprising the 3D printing has successfully carry out clinical applications artificial vertebral body related patents. Patent indicators covering technical indicators and indicators related to patent IPlytics by 3D printing market, patent portfolio can be a preliminary analysis of strengths, weaknesses and positioning.

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 application, GE, StratasysTechnology and Harvard University, the highest correlation score. According to patent litigation IPlytics data, between 2000 and 2018 in the United States of 3D printing up to 155 from patent litigation. 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, developed effective patent strategy can 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.
