Top Nanotechnology Patent Assignees at USPTO
Given the statistical data compiled by the Orbit Database, a total of 14,795 nanotechnology patents have been filed at the USPTO during the first 9 months of 2018. Reportedly, 6,409 of the patents are granted patents, while 8,386 of those are published patent applications.
The USPTO has been recognized as one of the world's leading patent offices. In view of the scores achieved for both granted patents and published patent applications, IBM, having the highest number of nanotechnology patent applications at the USPTO by the end of September 2018, has ranked first among all patent holders. This technology company, which is headquartered in Armonk, New York, operates in various fields including software and hardware, and also provides hosting and consulting services in areas ranging from mainframe computers to nanotechnology. Samsung Electronics Co., Ltd. and Samsung Display Co., Ltd., two Korean companies spun off from the Samsung Group, have taken the second and third places on the list, respectively. According to statistics, it is expected that these three companies will rank first to third considering their scores by the end of 2018, as they used to be in 2017.
Table 1 lists the top 20 patent assignees scored the highest number of nanotechnology patent applications for both granted patents and published patent applications at the USPTO during the first 9 months of 2018. The percentage of nanotechnology patents among all patents filed by each assignee is also shown in this table. Accordingly, it denotes that around 92% of the patents held by Nanotek Instruments, INC. are in the field of nanotechnology, while those of the other nineteen companies are below 40%.
