The verdict
Sparrow holds 6 US patents across 2 technology areas, rank #42,962 of 50,000 tracked assignees.
Sparrow Co., Ltd has been granted 6 US utility patents between 2019 and 2025, placing Sparrow Co., Ltd at rank #42,962 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.5 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, Sparrow Co., Ltd is one of the more focused assignees in the PatentsView dataset. By volume, Sparrow sits between Southeastern Metals Manufacturing Co. Inc. (6 patents, rank #42,958) and SPF Innovations, Llc (6 patents, rank #42,966) - the closest US assignees by grant volume. The composite Innovation Score of 21.3/100 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 3 grants, compared with 3 in the 2015–2019 window, a +0% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Sparrow Co., Ltd's 8.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sparrow Co., Ltd against peers pursuing similar technology classes.

How to use this portfolio
Sparrow's 6 grants land it in the top 92% 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.
