USPTO PatentsView assignee record - 136 granted patents across 21 technology areas, active 2020–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS).
The verdict
Playnitride holds 136 US patents across 21 technology areas, rank #2,829 of 50,000 tracked assignees.
Playnitride Display Co., Ltd. has been granted 136 US utility patents between 2020 and 2025, placing Playnitride Display Co., Ltd. at rank #2,829 across all assignees tracked by PlainPatent. This portfolio spans 21 distinct Cooperative Patent Classification (CPC) subclasses, averaging 13.5 claims per patent with primary concentration in H10H (INORGANIC LIGHT-EMITTING SEMICONDUCTOR DEVICES HAVING POTENTIAL BARRIERS). As a Foreign Corporation, Playnitride Display Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Playnitride sits between Kabushiki Kaisha Nihon Micronics (136 patents, rank #2,825) and Sion Power Corporation (136 patents, rank #2,833) - the closest US assignees by grant volume. The composite Innovation Score of 61.3/100 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. Historical data spans 2020 through 2025, with 136 total grants over that period. Velocity comparisons require five years of historical filings to calibrate. 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. Playnitride Display Co., Ltd.'s 13.5 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 21 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Playnitride Display Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Playnitride's 136 grants land it in the top 3% 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.
