Portfolio overview

Sanden Corporation has been granted 168 US utility patents between 2015 and 2025, placing Sanden Corporation at rank #2,336 across all assignees tracked by PlainPatent. This portfolio spans 55 distinct Cooperative Patent Classification (CPC) subclasses, averaging 9.1 claims per patent with primary concentration in B60H (ARRANGEMENTS OF HEATING, COOLING, VENTILATING OR OTHER AIR-TREATING DEVICES SPECIALLY ADAPTED FOR PASSENGER OR GOODS SPACES OF VEHICLES). As a Foreign Corporation, Sanden Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Sanden sits between NLT Technologies, Ltd. (168 patents, rank #2,332) and Tribune Broadcasting Company, Llc (168 patents, rank #2,340) - the closest US assignees by grant volume. The composite Innovation Score of 53.6/100 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. Between 2020 and 2025 the company received 52 grants, compared with 116 in the 2015–2019 window, a -55% 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. Sanden Corporation's 9.1 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 55 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Sanden 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.
