USPTO PatentsView assignee record - 151 granted patents across 49 technology areas, active 2017–2023. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS).
The verdict
Lotte holds 151 US patents across 49 technology areas, rank #2,576 of 50,000 tracked assignees.
Lotte Advanced Materials Co., Ltd. has been granted 151 US utility patents between 2017 and 2023, placing Lotte Advanced Materials Co., Ltd. at rank #2,576 across all assignees tracked by PlainPatent. This portfolio spans 49 distinct Cooperative Patent Classification (CPC) subclasses, averaging 12.6 claims per patent with primary concentration in C08L (COMPOSITIONS OF MACROMOLECULAR COMPOUNDS). As a Foreign Corporation, Lotte Advanced Materials Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Lotte sits between ASIA Optical Co., Inc. (151 patents, rank #2,572) and Sodick Co., Ltd. (151 patents, rank #2,580) - the closest US assignees by grant volume. The composite Innovation Score of 50.4/100 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 62 grants, compared with 89 in the 2015–2019 window, a -30% 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. Lotte Advanced Materials Co., Ltd.'s 12.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 49 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Lotte Advanced Materials Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Lotte's 151 grants land it in the top 13% 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.
