Portfolio overview

Prior Company Limited has been granted 9 US utility patents between 2015 and 2025, placing Prior Company Limited at rank #29,819 across all assignees tracked by PlainPatent. This portfolio spans 13 distinct Cooperative Patent Classification (CPC) subclasses, averaging 5.9 claims per patent with primary concentration in C08G (MACROMOLECULAR COMPOUNDS OBTAINED OTHERWISE THAN BY REACTIONS ONLY INVOLVING UNSATURATED CARBON-TO-CARBON BONDS). As a Foreign Corporation, Prior Company Limited is one of the more focused assignees in the PatentsView dataset. By volume, Prior sits between Pressure Systems International, Llc (9 patents, rank #29,815) and Prolight Opto Technology Corporation (9 patents, rank #29,823) - the closest US assignees by grant volume. The composite Innovation Score of 37.6/100 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 3 grants, compared with 6 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. Prior Company Limited's 5.9 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 13 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Prior Company Limited against peers pursuing similar technology classes.

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.
