Portfolio overview

Tachi-s Co., Ltd. has been granted 228 US utility patents between 2015 and 2025, placing Tachi-s Co., Ltd. at rank #1,787 across all assignees tracked by PlainPatent. This portfolio spans 29 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.6 claims per patent with primary concentration in B60N (SEATS SPECIALLY ADAPTED FOR VEHICLES; VEHICLE PASSENGER ACCOMMODATION NOT OTHERWISE PROVIDED FOR). As a Foreign Corporation, Tachi-s Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tachi-s sits between Universite De Montpellier (229 patents, rank #1,783) and Business Objects Software Ltd. (227 patents, rank #1,791) - the closest US assignees by grant volume. The composite Innovation Score of 44.1/100 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 98 grants, compared with 130 in the 2015–2019 window, a -25% 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. Tachi-s Co., Ltd.'s 7.6 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while a multi-domain presence across 29 subclasses balances depth with breadth. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tachi-s 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.
