The verdict
Bosal holds 24 US patents across 33 technology areas, rank #12,369 of 50,000 tracked assignees.
Bosal Emission Control Systems Nv has been granted 24 US utility patents between 2015 and 2023, placing Bosal Emission Control Systems Nv at rank #12,369 across all assignees tracked by PlainPatent. This portfolio spans 33 distinct Cooperative Patent Classification (CPC) subclasses, averaging 15.1 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 Foreign Corporation, Bosal Emission Control Systems Nv is one of the more focused assignees in the PatentsView dataset. By volume, Bosal sits between Birkenstock Sales Gmbh (24 patents, rank #12,365) and Bastille Networks, Inc. (24 patents, rank #12,373) - the closest US assignees by grant volume. The composite Innovation Score of 42.7/100 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 5 grants, compared with 19 in the 2015–2019 window, a -74% 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. Bosal Emission Control Systems Nv's 15.1 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 33 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Bosal Emission Control Systems Nv against peers pursuing similar technology classes.

How to use this portfolio
Bosal's 24 grants land it in the top 30% by Innovation Score, but volume alone doesn't tell you where the strength sits.
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.
