Portfolio overview

Mahle International Gmbh has been granted 1,224 US utility patents between 2015 and 2025, placing Mahle International Gmbh at rank #353 across all assignees tracked by PlainPatent. This portfolio spans 176 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.7 claims per patent with primary concentration in F28F (DETAILS OF HEAT-EXCHANGE AND HEAT-TRANSFER APPARATUS, OF GENERAL APPLICATION). As a Foreign Corporation, Mahle International Gmbh is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Mahle sits between HKC Corporation Limited (1,232 patents, rank #349) and Pixart Imaging Inc. (1,212 patents, rank #357) - the closest US assignees by grant volume. The composite Innovation Score of 64.3/100 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 550 grants, compared with 674 in the 2015–2019 window, a -18% 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. Mahle International Gmbh's 16.7 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a diversified footprint across 100+ CPC subclasses spreads risk across many technology fronts. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Mahle International Gmbh 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.
