Portfolio overview
Grand Rainbow International Limited has been granted 6 US utility patents between 2016 and 2019, placing Grand Rainbow International Limited at rank #40,529 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.5 claims per patent with primary concentration in A44C (PERSONAL ADORNMENTS, e.g. JEWELLERY; COINS). As a Foreign Corporation, Grand Rainbow International Limited is one of the more focused assignees in the PatentsView dataset. By volume, Grand sits between Graftek Imaging Inc. (6 patents, rank #40,525) and Great Basin Scientific, Inc. (6 patents, rank #40,533) - the closest US assignees by grant volume. The composite Innovation Score of 20.4/100 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 0 grants, compared with 6 in the 2015–2019 window, a -100% 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. Grand Rainbow International Limited's 12.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Grand Rainbow International Limited against peers pursuing similar technology classes.
