Portfolio overview

Yuyama Mfg. Co., Ltd. has been granted 104 US utility patents between 2015 and 2025, placing Yuyama Mfg. Co., Ltd. at rank #3,557 across all assignees tracked by PlainPatent. This portfolio spans 28 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.7 claims per patent with primary concentration in B65B (MACHINES, APPARATUS OR DEVICES FOR, OR METHODS OF, PACKAGING ARTICLES OR MATERIALS; UNPACKING). As a Foreign Corporation, Yuyama Mfg. Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Yuyama sits between Video Gaming Technologies, Inc. (104 patents, rank #3,553) and FLOS S.p.a. (103 patents, rank #3,561) - the closest US assignees by grant volume. The composite Innovation Score of 45.3/100 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 37 grants, compared with 67 in the 2015–2019 window, a -45% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Yuyama Mfg. Co., Ltd.'s 11.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 28 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Yuyama Mfg. 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.
