Portfolio overview

Tomoegawa Corporation has been granted 47 US utility patents between 2015 and 2025, placing Tomoegawa Corporation at #7,089 of 50,000 across all assignees tracked by PlainPatent. This portfolio spans 50 distinct Cooperative Patent Classification (CPC) subclasses, averaging 10.8 claims per patent with primary concentration in G02B (OPTICAL ELEMENTS, SYSTEMS OR APPARATUS). As a Foreign Corporation, Tomoegawa Corporation is one of the broader-portfolio assignees in the PatentsView dataset. By volume, Tomoegawa sits between Trinity Industrial Corporation (47 patents, rank #7,087) and University Of Newcastle Upon Tyne (47 patents, rank #7,095) - the closest US assignees by grant volume. The composite Innovation Score of 50.2/100 blends portfolio volume, grant velocity, technology breadth, and claim depth into a single comparable measure drawn directly from USPTO PatentsView records.

Grant cadence records the difference between two grant-year windows. Between 2020 and 2024 the company received 25 grants, compared with 14 in the 2015–2019 window, a +79% shift in five-year grant velocity. Both windows cover five complete grant years; the latest PatentsView year is a partial release and is excluded from this comparison, though it still appears in the yearly table and chart below. Grant timing can lag the related application by years, so this comparison does not establish current R&D spending, strategic intent, or a company’s application activity. The Foreign Corporation classification provides context for the assignee record, not a conclusion about its business strategy.

Claim depth and technology breadth describe this aggregate record. Tomoegawa Corporation's 10.8 average claims per patent is an average count, not a measure of claim scope, legal strength, enforceability, or design-around risk. The record spans 50 CPC subclasses. Combined with portfolio volume, these figures let readers compare the documented grant records of assignees in similar technology classes.
