Portfolio overview

Karsten Manufacturing Corporation has been granted 1,177 US utility patents between 2015 and 2025, placing Karsten Manufacturing Corporation at rank #370 across all assignees tracked by PlainPatent. This portfolio spans 57 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.1 claims per patent with primary concentration in A63B (APPARATUS FOR PHYSICAL TRAINING, GYMNASTICS, SWIMMING, CLIMBING, OR FENCING; BALL GAMES; TRAINING EQUIPMENT). As a US Corporation, Karsten Manufacturing Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Karsten sits between HRL Laboratories, Llc (1,188 patents, rank #366) and Volvo Truck Corporation (1,171 patents, rank #374) - the closest US assignees by grant volume. The composite Innovation Score of 62.8/100 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 694 grants, compared with 483 in the 2015–2019 window, a +44% shift in five-year velocity. Steady filing volume suggests sustained innovation without dramatic pivots. 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. Karsten Manufacturing Corporation's 13.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 57 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Karsten Manufacturing Corporation 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.
