USPTO PatentsView assignee record - 133 granted patents across 22 technology areas, active 2018–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES).
The verdict
DB holds 133 US patents across 22 technology areas, rank #2,876 of 50,000 tracked assignees.
DB Hitek Co., Ltd. has been granted 133 US utility patents between 2018 and 2025, placing DB Hitek Co., Ltd. at rank #2,876 across all assignees tracked by PlainPatent. This portfolio spans 22 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.3 claims per patent with primary concentration in H10D (INORGANIC ELECTRIC SEMICONDUCTOR DEVICES). As a Foreign Corporation, DB Hitek Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, DB sits between Alpha And Omega Semiconductor (cayman) Ltd. (133 patents, rank #2,872) and Hisense Visual Technology Co., Ltd. (133 patents, rank #2,880) - the closest US assignees by grant volume. The composite Innovation Score of 45.1/100 blends portfolio volume, filing velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.
Filing cadence tells the strategic story. Between 2020 and 2025 the company received 97 grants, compared with 36 in the 2015–2019 window, a +169% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. The Foreign Corporation classification further shapes interpretation, since corporate, government, and individual filers pursue patents for materially different reasons.
Claim depth and technology breadth together indicate competitive posture. DB Hitek Co., Ltd.'s 13.3 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 22 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark DB Hitek Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
DB's 133 grants land it in the top 24% by Innovation Score, but volume alone doesn't tell you where the strength sits.
Patent counts and the Innovation Score measure patenting activity, not commercial success or the legal strength of any patent. Many patents are filed defensively. Verify the status of an individual patent against official USPTO records.
