Portfolio overview

Kohjin LIFE Sciences Co., Ltd. has been granted 8 US utility patents between 2018 and 2023, placing Kohjin LIFE Sciences Co., Ltd. at rank #32,226 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.6 claims per patent with primary concentration in A23L (FOODS, FOODSTUFFS OR NON-ALCOHOLIC BEVERAGES, NOT OTHERWISE PROVIDED FOR; PREPARATION OR TREATMENT THEREOF). As a Foreign Corporation, Kohjin LIFE Sciences Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Kohjin sits between KMB Telematics, Inc. (8 patents, rank #32,222) and Kontek Industries, Inc. (8 patents, rank #32,230) - the closest US assignees by grant volume. The composite Innovation Score of 29.1/100 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 4 grants, compared with 4 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. Kohjin LIFE Sciences Co., Ltd.'s 8.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Kohjin LIFE Sciences Co., Ltd. against peers pursuing similar technology classes.

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.
