Portfolio overview
SEIKO PRECISION INC. has been granted 45 US utility patents between 2015 and 2020, placing SEIKO PRECISION INC. at rank #7,323 across all assignees tracked by PlainPatent. This portfolio spans 14 distinct Cooperative Patent Classification (CPC) subclasses, averaging 7.5 claims per patent with primary concentration in G03B (APPARATUS OR ARRANGEMENTS FOR TAKING PHOTOGRAPHS OR FOR PROJECTING OR VIEWING THEM; APPARATUS OR ARRANGEMENTS EMPLOYING ANALOGOUS TECHNIQUES USING WAVES OTHER THAN OPTICAL WAVES; ACCESSORIES THEREFOR). As a Foreign Corporation, SEIKO PRECISION INC. is one of the more focused assignees in the PatentsView dataset. The composite Innovation Score of 30.9/100 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 1 grants, compared with 44 in the 2015–2019 window — a -98% 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. SEIKO PRECISION INC.'s 7.5 average claims per patent suggests focused, narrowly drawn claims typical of single-invention filings, while concentration in 14 subclasses points to a focused technical program. Combined with portfolio volume, these signals let analysts, investors, and licensing professionals benchmark SEIKO PRECISION INC. against peers pursuing similar technology classes.

How to use this portfolio
Seiko's 45 grants land it in the top 64% by Innovation Score — but volume alone doesn't tell you where the strength sits.
- Read that count against the largest US assignees before treating it as dominance — Seiko ranks #7,323 of 50,000. Top 50 holders
- Most of this portfolio concentrates in G03B — see who else leads that technology area. G03B leaders
- Check what the four-part Innovation Score actually rewards before comparing it to another company. How the score works
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.
