USPTO PatentsView assignee record - 134 granted patents across 5 technology areas, active 2021–2025. Filing-trend and competitive-moat analysis cross-referenced to USPTO Patent Public Search. Primary class: G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS).
The verdict
Tokyo holds 134 US patents across 5 technology areas, rank #2,866 of 50,000 tracked assignees.
Tokyo Visionary Optics Co., Ltd. has been granted 134 US utility patents between 2021 and 2025, placing Tokyo Visionary Optics Co., Ltd. at rank #2,866 across all assignees tracked by PlainPatent. This portfolio spans 5 distinct Cooperative Patent Classification (CPC) subclasses, averaging 11.4 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Tokyo Visionary Optics Co., Ltd. is one of the more focused assignees in the PatentsView dataset. By volume, Tokyo sits between P-tech Co., Ltd. (134 patents, rank #2,862) and Andritz Inc. (133 patents, rank #2,870) - the closest US assignees by grant volume. The composite Innovation Score of 51.7/100 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 2021 through 2025, with 134 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. Tokyo Visionary Optics Co., Ltd.'s 11.4 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 5 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark Tokyo Visionary Optics Co., Ltd. against peers pursuing similar technology classes.

How to use this portfolio
Tokyo's 134 grants land it in the top 11% 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.
