Portfolio overview

Karl Storz Gmbh & Co. KG has been granted 322 US utility patents between 2015 and 2020, placing Karl Storz Gmbh & Co. KG at rank #1,318 across all assignees tracked by PlainPatent. This portfolio spans 42 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.7 claims per patent with primary concentration in A61B (DIAGNOSIS; SURGERY; IDENTIFICATION). As a Foreign Corporation, Karl Storz Gmbh & Co. KG is one of the more focused assignees in the PatentsView dataset. By volume, Karl sits between Trimble Inc. (323 patents, rank #1,314) and Nchain Licensing Ag (321 patents, rank #1,322) - the closest US assignees by grant volume. The composite Innovation Score of 47.5/100 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 320 in the 2015–2019 window, a -99% 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. Karl Storz Gmbh & Co. KG's 7.7 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 42 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Karl Storz Gmbh & Co. KG 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.
