The latest annual report fromIFI CLAIMS专利服务显示，3D打印已从2021年的2021年增长最快的技术中删除US Patent and Trademark Office（USPTO）数据。
报告编制企业、技术and countries that have received the most patents over the past year using the firm’s proprietary data platform. Just last year,3D打印被确定为IFI声明清单上的第九。
In fact, 2021 saw the “most precipitous drop” in total US patent grants in the past decade, declining seven percent from 2020. Grants went from 352,000 in 2020 to 327,329 during the past year, while published patent applications also saw a slight downtick of around one percent to 410,093.
“Last year saw the steepest decline in patent grants in the past decade,” said Mike Baycroft, CEO of IFI CLAIMS Patent Services.
“There could be many reasons for this – and clearly some are pandemic-related – but what we’re seeing is that corporations are still innovating at an impressive clip despite a challenging environment, particularly U.S. and Asia-based entities.”
3D打印的专利低迷
根据IFI的说法，专利活动可以为研究人员，分析师和投资者提供宝贵的财务指标，他们寻求对公司的研发生产力和IP战略的线索以及技术趋势以及各个行业中的竞争格局的了解。
Prior to taking ninth place last year, 3D printing was named as the第二个发展最快的技术in the 2017 edition of the report, after patent applications in the B33Y 40 (Additive Manufacturing; Auxiliary Operations or Equipment) patent classification saw a 35 percent compound annual growth rate (CAGR) between 2013 and 2017.
By contrast, IFI CLAIMS’ latest report reveals 3D printing patents with the CPC code B33Y 40 had a CAGR of just 19.6 percent for 2021, a figure that lost the technology its top 20 ranking.
确实使它进入前20位的技术包括基于生物模型的计算机系统，这是大型技术坚定者的重点，例如IBM，，，，Google，，，，Samsung，，，，Microsoftand英特尔，，，，and which saw a 54 percent CAGR increase from 2017-2021. Other fast-growing technologies in terms of patent data in 2021 included flowering plants, electrical smoking devices, quantum computing, machine learning and computer-aided design (CAD).

惠普仍然是专利图表的顶部
IFI声称的报告还显示，尽管美国的公司在2021年的专利赠款方面仍然高于国际同行，但总部位于中国的公司以比去年授予的专利高10％。
总部位于美国的公司占了USPTO在2021年授予的所有专利的一半以上，总计150,801。排名第二，是日本人的47,105，其次是韩国（21,264），中国（20,679）和德国（14,663）公司，他们占了前五名。
The enterprises with the greatest number of 3D printing 2021 published patent applications are listed as follows:
Hewlett Packard Development (HP) – 214
General Electric (GE) – 30
精工爱普生 - 28
桌面金属 - 23
碳 - 20
BothHPandGEhave maintained their rankings from last year, although both firms filed considerably fewer patent applications in 2021 compared to 2020. HP’s patent applications have more than halved from 470, while GE’s 2021 applications number just 10 percent of the 331 it filed last year.
前五名中的其他三个名字已更换Kinpo电子，，，，xyzprintingandBoeing，其中只有波音在第七名中排名前20位。值得注意的是，由于Kinpo电子和Xyzprinting都是子公司Kinpo Group，，，，2020saw the group file a total of 545 3D printing patents in 2020, which sees their omission from the top 20 this year as a particularly stark contrast.
Perhaps the trend that stands out the most from this year’s patent application figures is the sheer lack of volume compared to 2020. Between them, the top five enterprises named on IFI CLAIMS’ 2020 list published a total of 1,541 3D printing patents applications. In what appears to be a huge slump, the top five patent applicants of 2021 published just 315 between them last year.
