Portfolio overview

TPK Touch Solutions (xiamen) Inc. has been granted 182 US utility patents between 2015 and 2024, placing TPK Touch Solutions (xiamen) Inc. at rank #2,169 across all assignees tracked by PlainPatent. This portfolio spans 30 distinct Cooperative Patent Classification (CPC) subclasses, averaging 17.4 claims per patent with primary concentration in G06F (ELECTRIC DIGITAL DATA PROCESSING). As a Foreign Corporation, TPK Touch Solutions (xiamen) Inc. is one of the more focused assignees in the PatentsView dataset. By volume, TPK sits between Koenig & Bauer Ag (182 patents, rank #2,165) and Enphase Energy, Inc. (181 patents, rank #2,173) - the closest US assignees by grant volume. The composite Innovation Score of 51.1/100 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 39 grants, compared with 143 in the 2015–2019 window, a -73% 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. TPK Touch Solutions (xiamen) Inc.'s 17.4 average claims per patent sits within the typical range for solid legal coverage without excessive prosecution cost, while a multi-domain presence across 30 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark TPK Touch Solutions (xiamen) Inc. against peers pursuing similar technology classes.
