Portfolio overview

Shiraishi Kogyo Kaisha, Ltd. has been granted 10 US utility patents between 2015 and 2024, placing Shiraishi Kogyo Kaisha, Ltd. at rank #27,344 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.4 claims per patent with primary concentration in C08K (Use of inorganic or non-macromolecular organic substances as compounding ingredients). As a Foreign Corporation, Shiraishi Kogyo Kaisha, Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shiraishi sits between Shenzhen VMAX NEW Energy Co., Ltd. (10 patents, rank #27,340) and Sightline Innovation Inc. (10 patents, rank #27,348) - the closest US assignees by grant volume. The composite Innovation Score of 28.1/100 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 7 grants, compared with 3 in the 2015–2019 window, a +133% 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. Shiraishi Kogyo Kaisha, Ltd.'s 5.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shiraishi Kogyo Kaisha, Ltd. against peers pursuing similar technology classes.
