Portfolio overview

Purdue Research Foundation has been granted 1,690 US utility patents between 2015 and 2025, placing Purdue Research Foundation at rank #251 across all assignees tracked by PlainPatent. This portfolio spans 326 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.9 claims per patent with primary concentration in G01N (INVESTIGATING OR ANALYSING MATERIALS BY DETERMINING THEIR CHEMICAL OR PHYSICAL PROPERTIES). As a US Corporation, Purdue Research Foundation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Purdue sits between Wuhan China STAR Optoelectronics Semiconductor Display Technology Co., Ltd. (1,717 patents, rank #247) and THE Regents OF THE University OF Michigan (1,666 patents, rank #255) - the closest US assignees by grant volume. The composite Innovation Score of 67.4/100 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 1,073 grants, compared with 617 in the 2015–2019 window, a +74% shift in five-year velocity. An acceleration of this magnitude signals aggressive R&D investment and expanding technical ambition. 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. Purdue Research Foundation's 14.9 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Purdue Research Foundation against peers pursuing similar technology classes.

How to use this portfolio

Purdue's 1,690 grants land it in the top 1% 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 - Purdue ranks #251 of 50,000. Top 50 holders
  • Most of this portfolio concentrates in G01N - see who else leads that technology area. G01N 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.
