The total value of Infineon’s semiconductor discrete device patents is higher than that of Texas Instruments. The total value of Infineon’s and Texas Instruments’ semiconductor discrete device patents is $573 million and $345 million, respectively. In terms of the distribution of patent value, most of the patent values of semiconductor discrete devices of the two companies are concentrated in 30,000-300,000 US dollars.
(3) Regional comparison of patent applications: the United States is the main layout area of the two
At present, Texas Instruments and Infineon’s semiconductor discrete device patent application areas are mainly concentrated in the United States, and the number of semiconductor discrete device patents they have applied for in the United States is 1647 and 1269 respectively.
Statistical caliber description: Statistics are carried out according to the deduplication rule that each application displays a public text, and the latest text on the public date is selected for calculation.
(4) Comparison of patent types: both are the most invention patents
Texas Instruments and Infineon’s semiconductor discrete device patent applications are the most invention patents. Texas Instruments and Infineon each have 1 and 5 utility model patents for semiconductor discrete devices, and the others are invention patents.
(5) Comparison of the composition of patented technologies: the first major segment of the layout of the two is inconsistent, and the focus of Infineon is more obvious
Currently, “Semiconductor devices specially adapted for rectification, amplification, oscillation or switching and having at least one potential jump barrier or surface barrier; having at least one potential jump barrier or surface barrier, such as a PN junction depletion layer or capacitors or resistors with a carrier accumulation layer; parts of semiconductor bodies or their electrodes (H01L31/00 to H01L47/00, H01L51/05 preferred; parts other than semiconductors or their electrodes into H01L23/00; by A device composed of multiple solid-state components formed in or on a common substrate (H01L27/00)[2,6]” is Infineon’s largest semiconductor discrete device technology subdivision field, and the number of patent applications is 231 items; “Methods or apparatuses specially suitable for the manufacture or processing of semiconductors or solid-state devices or their components[2,8]” is Texas Instruments’ largest semiconductor discrete device technology subdivision field, with 189 patent applications. The technical layout of other key segments of the two semiconductor discrete devices is as follows:
From the field of semiconductor discrete device patent focus, Infineon’s semiconductor discrete device patent focus field is obvious at present, which mainly focuses on semiconductors, transistors, diodes, power semiconductors and other fields.
(6) Comparison of key patent layouts: Texas Instruments has been cited more times, and Infineon has a large patent family
