Portfolio overview

C&U Company Limited. has been granted 6 US utility patents between 2024 and 2024, placing C&U Company Limited. at rank #39,285 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 8.0 claims per patent with primary concentration in F16C (SHAFTS; FLEXIBLE SHAFTS; ELEMENTS OR CRANKSHAFT MECHANISMS; ROTARY BODIES OTHER THAN GEARING ELEMENTS; BEARINGS). As a Foreign Corporation, C&U Company Limited. is one of the more focused assignees in the PatentsView dataset. By volume, C&u sits between C & J Clark International Limited (6 patents, rank #39,281) and C.r.d. Centro Ricerche Ducati Trento S.r.l. (6 patents, rank #39,289) - the closest US assignees by grant volume. The composite Innovation Score of 37.6/100 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. Historical data spans 2024 through 2024, with 6 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. C&U Company Limited.'s 8.0 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark C&U Company Limited. against peers pursuing similar technology classes.
