Portfolio overview

Tamura Corporation has been granted 135 US utility patents between 2015 and 2025, placing Tamura Corporation at rank #2,854 across all assignees tracked by PlainPatent. This portfolio spans 43 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.4 claims per patent with primary concentration in H01L (SEMICONDUCTOR DEVICES NOT COVERED BY CLASS H10). As a Foreign Corporation, Tamura Corporation is one of the more focused assignees in the PatentsView dataset. By volume, Tamura sits between Sanechips Technology Co., Ltd. (135 patents, rank #2,850) and Hendrickson USA, L.l.c. (134 patents, rank #2,858) - the closest US assignees by grant volume. The composite Innovation Score of 50.8/100 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 68 grants, compared with 67 in the 2015–2019 window, a +1% 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. Tamura Corporation's 9.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 43 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tamura Corporation 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.
