Portfolio overview

Welch Allyn, Inc. has been granted 370 US utility patents between 2015 and 2025, placing Welch Allyn, Inc. at rank #1,146 across all assignees tracked by PlainPatent. This portfolio spans 58 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.4 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a US Corporation, Welch Allyn, Inc. is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Welch sits between Dentsply Sirona Inc. (370 patents, rank #1,142) and Oakley, Inc. (369 patents, rank #1,150) - the closest US assignees by grant volume. The composite Innovation Score of 57.9/100 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 174 grants, compared with 196 in the 2015–2019 window, a -11% shift in five-year velocity. A cooling filing rate may reflect portfolio consolidation, shifting priorities, or reduced R&D throughput. 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. Welch Allyn, Inc.'s 14.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 58 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Welch Allyn, Inc. 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.
