Portfolio overview

Shanghai Tianma Am-oled Co., Ltd. has been granted 351 US utility patents between 2015 and 2023, placing Shanghai Tianma Am-oled Co., Ltd. at rank #1,209 across all assignees tracked by PlainPatent. This portfolio spans 40 distinct Cooperative Patent Classification (CPC) subclasses, averaging 16.6 claims per patent with primary concentration in H10K (ORGANIC ELECTRIC SOLID-STATE DEVICES). As a Foreign Corporation, Shanghai Tianma Am-oled Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Shanghai sits between Seiko Instruments Inc. (352 patents, rank #1,205) and Gamblit Gaming, Llc (350 patents, rank #1,213) - the closest US assignees by grant volume. The composite Innovation Score of 53.3/100 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 175 grants, compared with 176 in the 2015–2019 window, a -1% 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. Shanghai Tianma Am-oled Co., Ltd.'s 16.6 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 40 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Shanghai Tianma Am-oled Co., Ltd. against peers pursuing similar technology classes.

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.
