Portfolio overview

Learjet Inc. has been granted 9 US utility patents between 2016 and 2019, placing Learjet Inc. at rank #29,240 across all assignees tracked by PlainPatent. This portfolio spans 18 distinct Cooperative Patent Classification (CPC) subclasses, averaging 20.0 claims per patent with primary concentration in B64C (AEROPLANES; HELICOPTERS). As a US Corporation, Learjet Inc. is one of the more focused assignees in the PatentsView dataset. By volume, Learjet sits between Laserssel Co., Ltd. (9 patents, rank #29,236) and LENA Foundation (9 patents, rank #29,244) - the closest US assignees by grant volume. The composite Innovation Score of 35.0/100 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 0 grants, compared with 9 in the 2015–2019 window, a -100% 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. Learjet Inc.'s 20.0 average claims per patent reflects complex, broadly scoped inventions that are difficult for competitors to design around, while concentration in 18 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Learjet Inc. against peers pursuing similar technology classes.

Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works

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.
