Portfolio overview

C° Change Surgical Llc has been granted 9 US utility patents between 2016 and 2023, placing C° Change Surgical Llc at rank #28,520 across all assignees tracked by PlainPatent. This portfolio spans 7 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.4 claims per patent with primary concentration in A61F (FILTERS IMPLANTABLE INTO BLOOD VESSELS; PROSTHESES; DEVICES PROVIDING PATENCY TO, OR PREVENTING COLLAPSING OF, TUBULAR STRUCTURES OF THE BODY, e.g. STENTS; ORTHOPAEDIC, NURSING OR CONTRACEPTIVE DEVICE). As a US Corporation, C° Change Surgical Llc is one of the more focused assignees in the PatentsView dataset. By volume, C° sits between Curevac Real Estate Gmbh (9 patents, rank #28,516) and Dairymaster (9 patents, rank #28,524) - the closest US assignees by grant volume. The composite Innovation Score of 29.9/100 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 2 grants, compared with 7 in the 2015–2019 window, a -71% 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. C° Change Surgical Llc's 15.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while concentration in 7 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark C° Change Surgical Llc 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.
