Across all tracked assignees
USPTO PatentsView assignee record - 9 granted patents across 3 technology areas, active 2015–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: F41J (TARGETS; TARGET RANGES; BULLET CATCHERS).
The verdict
Laporte holds 9 US patents across 3 technology areas, rank #29,235 of 50,000 tracked assignees.
Laporte Holding has been granted 9 US utility patents between 2015 and 2023, placing Laporte Holding at rank #29,235 across all assignees tracked by PlainPatent. This portfolio spans 3 distinct Cooperative Patent Classification (CPC) subclasses, averaging 14.2 claims per patent with primary concentration in F41J (TARGETS; TARGET RANGES; BULLET CATCHERS). As a Foreign Corporation, Laporte Holding is one of the more focused assignees in the PatentsView dataset. By volume, Laporte sits between Lamkin Corporation (9 patents, rank #29,231) and LDJ Manufacturing, Inc. (9 patents, rank #29,239) - the closest US assignees by grant volume. The composite Innovation Score of 29.3/100 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 1 grants, compared with 8 in the 2015–2019 window, a -87% 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. Laporte Holding's 14.2 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while specialization in 3 subclasses reflects a tightly scoped invention area. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Laporte Holding against peers pursuing similar technology classes.

How to use this portfolio
Laporte's 9 grants land it in the top 70% 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.
