Portfolio overview
Plexus Holdings Plc has been granted 6 US utility patents between 2015 and 2024, placing Plexus Holdings Plc at rank #42,412 across all assignees tracked by PlainPatent. This portfolio spans 2 distinct Cooperative Patent Classification (CPC) subclasses, averaging 22.5 claims per patent with primary concentration in E21B (EARTH OR ROCK DRILLING; OBTAINING OIL, GAS, WATER, SOLUBLE OR MELTABLE MATERIALS OR A SLURRY OF MINERALS FROM WELLS). As a Foreign Corporation, Plexus Holdings Plc is one of the more focused assignees in the PatentsView dataset. By volume, Plexus sits between Plastic Safety Systems, Inc. (6 patents, rank #42,408) and Pocket Naloxone Corp. (6 patents, rank #42,416) - the closest US assignees by grant volume. The composite Innovation Score of 38.6/100 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. Between 2020 and 2025 the company received 2 grants, compared with 4 in the 2015–2019 window, a -50% 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. Plexus Holdings Plc's 22.5 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while specialization in 2 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Plexus Holdings Plc against peers pursuing similar technology classes.
