The verdict
Proseal holds 5 US patents across 6 technology areas, rank #49,836 of 50,000 tracked assignees.
Proseal UK Limited has been granted 5 US utility patents between 2022 and 2025, placing Proseal UK Limited at rank #49,836 across all assignees tracked by PlainPatent. This portfolio spans 6 distinct Cooperative Patent Classification (CPC) subclasses, averaging 19.6 claims per patent with primary concentration in B65B (MACHINES, APPARATUS OR DEVICES FOR, OR METHODS OF, PACKAGING ARTICLES OR MATERIALS; UNPACKING). As a Foreign Corporation, Proseal UK Limited is one of the more focused assignees in the PatentsView dataset. By volume, Proseal sits between Prognomiq, Inc. (5 patents, rank #49,832) and Protagen Ag (5 patents, rank #49,840) - the closest US assignees by grant volume. The composite Innovation Score of 46.6/100 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. Historical data spans 2022 through 2025, with 5 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Proseal UK Limited's 19.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 6 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Proseal UK Limited against peers pursuing similar technology classes.

How to use this portfolio
Proseal's 5 grants land it in the top 20% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
