Portfolio overview

Tenneco Automotive Operating Company Llc has been granted 266 US utility patents between 2015 and 2025, placing Tenneco Automotive Operating Company Llc at rank #1,561 across all assignees tracked by PlainPatent. This portfolio spans 56 distinct Cooperative Patent Classification (CPC) subclasses, averaging 18.6 claims per patent with primary concentration in F01N (GAS-FLOW SILENCERS OR EXHAUST APPARATUS FOR MACHINES OR ENGINES IN GENERAL; GAS-FLOW SILENCERS OR EXHAUST APPARATUS FOR INTERNAL-COMBUSTION ENGINES). As a US Corporation, Tenneco Automotive Operating Company Llc is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Tenneco sits between Biotronik SE & Co. KG (266 patents, rank #1,557) and Ledvance Gmbh (265 patents, rank #1,565) - the closest US assignees by grant volume. The composite Innovation Score of 59.3/100 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 111 grants, compared with 155 in the 2015–2019 window, a -28% 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. Tenneco Automotive Operating Company Llc's 18.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 56 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tenneco Automotive Operating Company Llc against peers pursuing similar technology classes.
