Portfolio overview
INPHI CORPORATION has been granted 491 US utility patents between 2015 and 2021, placing INPHI CORPORATION at rank #911 across all assignees tracked by PlainPatent. This portfolio spans 35 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.2 claims per patent with primary concentration in H04B (TRANSMISSION). As a US Corporation, INPHI CORPORATION is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 53.8/100 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 105 grants, compared with 386 in the 2015–2019 window — a -73% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. The US 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. INPHI CORPORATION's 19.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 35 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark INPHI CORPORATION against peers pursuing similar technology classes.
