Portfolio overview

Cooler Master Co., Ltd. has been granted 185 US utility patents between 2015 and 2025, placing Cooler Master Co., Ltd. at rank #2,128 across all assignees tracked by PlainPatent. This portfolio spans 48 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.7 claims per patent with primary concentration in H05K (PRINTED CIRCUITS; CASINGS OR CONSTRUCTIONAL DETAILS OF ELECTRIC APPARATUS; MANUFACTURE OF ASSEMBLAGES OF ELECTRICAL COMPONENTS). As a Foreign Corporation, Cooler Master Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Cooler sits between University Of Hong Kong (186 patents, rank #2,124) and Petróleo Brasileiro S.a.—petrobras (185 patents, rank #2,132) - the closest US assignees by grant volume. The composite Innovation Score of 58.7/100 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 125 grants, compared with 60 in the 2015–2019 window, a +108% 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. Cooler Master Co., Ltd.'s 13.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 48 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Cooler Master 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.
