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. By volume, Inphi sits between Citizen Watch Co., Ltd. (494 patents, rank #907) and Biomet Manufacturing, Llc (488 patents, rank #915) - the closest US assignees by grant volume. 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.

How to use this portfolio

Inphi's 491 grants land it in the top 8% by Innovation Score, but volume alone doesn't tell you where the strength sits.

  • Read that count against the largest US assignees before treating it as dominance - Inphi ranks #911 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in H04B - see who else leads that technology area. H04B leaders
  • Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
